Coincubation of these two compounds in human liver microsomes yields significant inhibition of carbaryl metabolism, even at low doses. The extent to which such interactions contributed to adverse effects of Gulf War exposures and the development of Gulf War illness can not be deduced from studies of this type. But this information provides extremely useful insights into specific biochemical processes potentially involved in interactions between combinations of Gulf War exposures. Information from this research can also improve assessments that extrapolate findings on biological effects of Gulf War exposures from animal studies to humans. Scientific understanding of the specific biological effects of combinations of chemical exposures on human health is relatively limited. These studies have demonstrated diverse effects resulting from combinations of neurotoxicant exposures, which differ from those of individual chemicals. As shown, the earliest studies of this type were conducted in the middle and late 1990s, and used exposure protocols that differed in important ways from Gulf War-related exposures. These studies were important, however, for providing a first look at the potential for synergistic effects of combinations of Gulf War-related exposures on the central nervous system. Since 2001, multiple studies have used animal exposure models that provided a closer approximation to the types and levels of exposures experienced by Gulf War military personnel. Many of those studies have been conducted by Duke University investigators, and are noteworthy for two important reasons. First, the exposure models used were specifically developed to parallel exposures during the Gulf War. Second, many of the Duke studies evaluated effects that developed after an extended exposure period. Following up above study, evaluated changes in brain regions in which no disruption of blood brain barrier occurred. As a result, these studies have been extremely valuable not only for describing synergistic effects of multiple exposures, but also for characterizing central nervous system effects of single exposures, delivered orally and to the skin using a repeated dosing schedule over an extended period of time. As summarized in Table 6, these studies have produced an extensive number of detailed findings. In addition, studies utilizing Gulf War-relevant protocols have identified diverse interactions between different mixtures of cholinergic neurotoxicants and insect repellants used in the Gulf War. It is important to note that different studies have evaluated different exposure combinations and durations, and that the majority of synergistic effects reported have been identified by only one or two studies, usually from the same team of investigators. These studies are generally consistent in showing that combined exposures can produce synergistic effects. However, many of the specific effects identified can only be considered preliminary, pending additional investigation. It is also important to note that relatively few three-way interactions were identified in these studies. That is, few synergistic effects resulting from combinations of three compounds were identified that differed from those observed with only two of the compounds. This combination produced significant increases in blood brain barrier permeability in four regions-the cingulate cortex, the dentate gyrus, the thalamus, and the hypothalamus. This response was consistent with reported indicators of neuronal cell death in those regions, as well as in the cerebral cortex and hippocampus. Findings indicative of neuronal cell death in these studies have been challenged by a suggestion that the dark neurons described as indicating cell death in exposed animals may be an experimental artifact that can be produced by a number of experimental conditions. Combinations of lindane, malthion, and, permethrin have been reported to act synergistically to increase markers of oxidative stress, stimulate increased levels of antioxidant enzymes, and produce necrotic and apoptotic cell death in thymocytes. During the treadmill session, subjects watched a video depicting battle scenes from popular movies, and also performed mental arithmetic stress tests. The trial identified few differences between treatment and placebo groups on measures of neurobehavioral function, physical performance, or blood hormone levels. The study was useful in showing that brief use of these products, at levels similar to or below those directed by current military policy, does not produce acute, observable adverse effects in military personnel. These included effects on the brain and behavior, on autonomic function, and on peripheral metabolizing enzymes and muscle function. Some alterations were most pronounced two or four weeks after exposure, with values similar to unexposed controls at later time points. Most importantly, it is unknown whether time-related effects identified by some studies persisted or changed further at time points beyond those included in the study.

Interactions with school personnel, public health nurses, social workers, various therapists (such as speech/language therapists, occupational therapists, physical therapists), early Page - 18 childhood educators or daycare providers are a common part of pediatric practice today. Learning to interact appropriately with these individuals, and to gain from their expertise, is an important part of pediatric training. Although there is a perception that office based pediatrics is largely limited to runny noses and ear infections, in fact there is a wide realm of issues and problems that a pediatrician may become involved in. The nature of the practice will depend to some extent on the ease of availability of subspeciality care, but will also depend on personal characteristics of the pediatrician that determine the practice style he or she is most comfortable with. True/False: When caring for pediatric patients, it is always more appropriate to use pediatric subspecialists than specialists who may be primarily trained to work with adults. True/False: There is a standard for after hours accessibility that all pediatricians adhere to. True/False: There is variability in the use of pediatric subspecialty care that results from factors other than availability of specialists. If a pediatric subspecialist is not available, the pediatrician has the following choices: a. Send the patient to a pediatric subspecialist regardless of cost and inconvenience. Pediatricians may be concerned about giving after hours telephone advice to parents who call. A general surgeon practicing in a small town might be the best person to handle a suspected case of appendicitis, for example. Although some third party payors have standards written into their contracts with physicians, and the American Academy of Pediatrics has created a standard, not all pediatricians adhere to these standards. Many factors are involved, including the training of the primary care pediatrician and past experience with similar cases. She was born at 39-4/7 weeks gestation by normal spontaneous vaginal delivery without any complications. At birth, her weight was 3856 g, length 53 cm, head circumference 34 cm, and chest circumference 35. She has been breast-fed since birth, although her mother started to also use formula between one to two months of age. She is now being breast-fed once a day, given pumped breast milk in a bottle two to three times a day, and formula the rest of the time (about 16 oz or 480 ml per day). Her past medical history is otherwise significant for a vibratory heart murmur heard from the second week of life, which was thought to be innocent. Her heart murmur has resolved and the rest of her examination is otherwise normal. It is not only essential for the general pediatrician, but for other subspecialties as well. An aberration in growth patterns is often the first clue that there is something wrong with the child. Often, the growth of the child is used in conjunction with other signs and symptoms, to help the physician determine what the problem might be. An older child who is not gaining weight could be the first clue to inflammatory bowel disease. There are two age group specific growth charts, one for children from birth to 36 months of age, and another from 2 years to 20 years of age. The larger, pooled data sets used to create the revised charts eliminate the problem of differing percentiles when making the transition from recumbent length to stature height. Other new features of the new growth charts are the extension to 20 years because of sufficient data being available and its desirability for general populations, particularly for clinics dealing with endocrine disorders and congenital abnormalities (1). It should be noted that these growth charts are reflective of the population who are healthy and born at term. There are other growth charts available for children with various conditions, such as Turner, Klinefelter and Down syndromes and achondroplasia (2). Special growth charts for premature babies are also available by Babson and Benda that are based on gestational rather than chronological age, beginning at 26 weeks of gestation (3).

We believe that with early recognition of a staphylococcal toxin-related illness, hypotension may be averted by administration of fluids and antibiotics. In 1952 Eagle demonstrated a reduced efficacy of penicillin with high inoculum size (21). Erythromycin-treated mice fared better than penicillin-treated mice and untreated controls, but only if treatment was started within 2 hours. However clindamycin-treated mice had survival rates of 100%, 100%, 80%, and 70%, even if treatment was delayed for 0, 2, 6, and 16. Clindamycin suppresses synthesis of penicillin-binding proteins and it has a longer post-antibiotic effect than beta-lactams. With use of vasoconstrictors such as epinephrine, gangrene of the digits and toes often develops (10).

Known as "consumption", the white plague, and the white death, tuberculosis is perhaps the earliest, documented bacterial disease of humanity. Because of its characteristic pulmonary scarring and bony changes, it has been documented in human remains as ancient and diverse as the Egyptian and Incan mummies to the sand preserved natural remains found in the Chinese deserts of Asia Minor. In the late part of the 19th and early part of the 20th century, almost all adults showed evidence of exposure and immune response to Mycobacterium tuberculosis. In a special on War on Disease, National Geographic reported that one third of humanity are now carriers of tuberculosis (1). In the United States in general, and Hawaii in specific, there has been a rapid decrease in tuberculosis because of dramatic improvement in the living conditions of city dwellers (sociologic), the recognition of the means of spread the disease (epidemiological), isolation of contagious individuals in sanatoriums, as well as the development of anti-tuberculosis chemotherapy (bacteriologic and antimicrobial). Indeed, tuberculosis was considered a vanishing disease and the medical specialists in this field and the public health resources spent on it were vanishing as well. Hawaii has always had rates of infection much higher than the rest of the country. It is also clear that most newly diagnosed cases are imported and occur in foreign-born individuals (4). In Hawaii, these are patients are from Southeast Asia and the West Pacific Islands. From these data, the highest risk individuals are foreign born and are diagnosed soon after coming to Hawaii. It can involve any organ, can range from having no symptoms to overwhelming symptoms, progress indolently or become rapidly fatal, can be local or systemic. It is to be read at 48-72 hours although a positive result can be read up to 7 days after testing. False negatives occur both with improper placement of the antigen as well as when immunity decreases or is interfered with by other disease.

Seal the bag by pressing down on the "zipper" at the end of the bag with fingers and slide along to the opposite end. Transit time may be extended and viability and recovery enhanced by incubating before mailing. This selective medium contains the antimicrobial agents vancomycin, colistin, anisomycin (V-C-A Inhibitor) and trimethoprim, to suppress the normal flora. Colistin inhibits gram-negative bacteria, including Pseudomonas species, but is not active against Proteus species. If isolated colonies are present on the agar surface of the medium, pick colonies for Gram staining, oxidase testing and for carbohydrate fermentation studies. Colonies may be selected for Gram staining, subculturing or other diagnostic procedures. Maximum recovery Diluent Intended Use Maximum Recovery Diluent is an isotonic diluent containing a low level of peptone used for maintaining the viability of organisms during dilution procedures. Standard methods for the microbiological examination of foodstuffs require sample dilution to be carried out accurately to estimate the number of microorganisms. Diluents consisting of sterile saline, phosphate buffer solutions and distilled water have all been shown to have a lethal action on a wide range of organisms. Procedure g g Consult appropriate references for dilution procedures when testing foods. Principles of the Procedure McClung Toabe Agar Base contains peptone as a source of carbon, nitrogen, vitamins and minerals. Disodium phosphate and monopotassium phosphate maintain pH balance and provide a source of phosphates. Principles of the Procedure Turbidity standards are prepared by mixing chemicals that precipitate to form a solution of reproducible turbidity. Using adequate light, compare the turbidity of a bacterial suspension to the turbidity standard by holding the tubes against a white background with contrasting horizontal black lines. Alternatively, use the turbidity standard to standardize electrometric turbidimeters. Methods for dilution antimicrobial susceptibility tests for bacteria that grow aerobically, 7th ed. Micro Inoculum Broth is used for preparing the inoculum of lactobacilli and other microorganisms used in microbiological assays of vitamins and amino acids. Solution is light to medium amber, very slightly to slightly opalescent without significant precipitate. Micro Assay Culture Agar is used for maintaining stock cultures of lactobacilli and other test microorganisms. Micro Inoculum Broth is used for cultivating lactobacilli and preparing the inoculum for microbiological assays. Precautions Great care must be taken to avoid contamination of media or glassware used in microbiological assay procedures. Subculture from a 16-24 hour stock culture of lactobacilli in Micro Assay Culture Agar into a 10 mL tube of Micro Inoculum Broth. Where applicable, adjust inoculum concentration according to limits specified in the references. Test organisms used in assay procedures must be cultured and maintained on media recommended for this purpose. The age, preparation and size of inoculum are extremely important factors in obtaining a satisfactory assay result. Although other media and methods may be used successfully for maintaining cultures and preparing inocula, uniformly good results will be obtained if the methods described are followed exactly. The use of altered or deficient media may create mutants having different nutritional requirements. Prepare stock cultures in triplicate on Micro Assay Culture Agar, inoculating tubes using a straight-wire inoculating needle.

Giving 5 cc every minute results in a maximum fluid administration rate of 300 cc per hour, but this is very labor intensive for parents who must do this continuously for it to work. More commonly, 30 cc (1 ounce) is given every 15 minutes which results in a maximum fluid administration rate of only 120 cc per hour. It should be noted that a major difference between the clinical utilization of oral rehydration in the U. While parents in other countries may be willing to administer 5 cc every 1 to minutes, while the child continues to have a few emesis episodes, American parents are not likely to be this persistent. Children in poorer countries do not have this option and despite sustaining greater degrees of dehydration, they are satisfactorily rehydrated via the oral route. It can be said that oral rehydration usually works for parents who are willing to persevere. Children with mild dehydration can be placed on near normal diets (avoiding fat and excessive sugar), with good results in most instances. For severe dehydration, this should be given as a rapid bolus (over less than 10 minutes), but for mild dehydration this can be given over one hour. Since fluid follows osmotic particles, the fluid volume will go, where the osmotic particles go. These ions stay within the circulating plasma and thus, the fluid volume expands the intravascular space preferentially. This might promote cellular edema under some circumstances, but at the very least, the fluid does not effectively expand the intravascular space. The 2% is determined by 400 cc divided by 20 kg (20,000 gms), or by 20 cc/kg (20 cc per 1000 cc = 2%). Another way to appreciate the truly small size of this fluid volume infusion is to equate this to soft drink cans, which are 12 ounce cans. Since 1 ounce equals 30 cc, a typical 12 ounce soft drink can contains 360 cc, which is similar to the 400 cc fluid infusion. Most 4 year olds can drink 3 or 4 soft drink cans on a hot day after a soccer game. For severe dehydration in the range of 15%, the patient would actually need 150 cc/kg to fully replace the fluid deficit. For a patient with 5% dehydration, the patient would actually need 50 cc/kg to fully replace the fluid deficit. In most instances, fully rehydrating the patient very rapidly is not necessary and this may be harmful if excessive fluid shifts occur. Once satisfactory fluid resuscitation has stabilized the patient, continued rehydration and maintenance fluids can be administered more gradually. Oral rehydration requires more work on the part of parents and some uncertainty exists as to whether it will be successful. Put yourself in the body of the child who is experiencing the vomiting and diarrhea. Imagine that you/he/she has vomited 8 times and has had 7 episodes of diarrhea beginning 8 hours ago. At this level, sufficient discomfort has been sustained by the patient and mild dehydration is likely. Most mildly dehydrated patients who are given 20 cc/kg per hour for 2 hours (total 40 cc/kg), feel much better with less nausea and fatigue. For such mild patients, they can usually be discharged from the emergency department to catch up on some rest. After a nap or overnight rest, oral rehydration attempts can resume, which are likely to be successful. Compare this to a similar oral rehydration patient, who is not permitted a nap and a period of bowel rest, and who must continue oral rehydration. However, this knowledge is generally required for medical students and pediatric residents. Fluid administration over a 24 hour period consists of deficit replacement plus maintenance administration. This is best described with the example presented in the case at the beginning of the chapter. A 12 month old male with vomiting and diarrhea is assessed to be 5% dehydrated by clinical criteria.

The addition of ferric ammonium citrate to the medium is used to detect sulfite reduction. Differential Reinforced Clostridial Medium (broth) was developed by Gibbs and Freame in 1965. Blackening of the medium is presumptive evidence for the presence of sulfite-reducing clostridia. In this method, heat-shocked tubes showing blackening are confirmatory for clostridia. Solution is light to medium amber, clear to slightly opalescent while hot; upon cooling, solution becomes light red. Inoculate samples onto the surface of agar plates using the streak plate or spread plate technique. Agar deeps may be incubated under aerobic conditions when following the Prickett tube method. Heat-shocked tubes showing blackening should be considered confirmatory for the presence of sulfite-reducing clostridia. Dubos Oleic Agar Base is used with Dubos Oleic Albumin Complex and penicillin for isolating and determining the susceptibility of M. Dubos Broth, Enriched is a prepared medium used for the cultivation of pure cultures of M. Dubos Broth, Enriched is a modified medium based on the formulation of Dubos et al. It is also used as a subculture and enrichment medium for the rapid cultivation of M. In comparative studies, Dubos Oleic Albumin Agar Medium was superior to other media studied for primary isolation. Lowenstein formulations are examples of media that contain egg; Middlebrook and Dubos formulations contain agar. Agar based media are not liquefied by contaminating proteolytic organisms but overgrowth may occur. Drugs may be added to Dubos media in exact concentrations because the medium is solidified with agar rather than by inspissation. Disodium phosphate and monopotassium phosphate are sources of phosphates and, along with calcium chloride, help maintain the pH of the medium. Magnesium sulfate, ferric ammonium sulfate, zinc sulfate and copper sulfate are sources of trace metals and sulfates. Polysorbate 80, an oleic acid ester, supplies essential fatty acids for the replication of mycobacteria. Bovine albumin acts as a protective agent by binding free fatty acids that may be toxic to mycobacteria. The albumin is heat-treated to inactivate lipase, which may release fatty acids from the polysorbate 80. Biosafety Level 2 practices, containment equipment and facilities are required for non-aerosol-producing manipulations of clinical specimens such as preparation of acid-fast smears. Biosafety Level 3 practices, containment equipment and facilities are required for laboratory activites in the propagation and manipulation of cultures of M. Aseptically add 20 mL Dubos Oleic Albumin Complex and 5,000-10,000 units of penicillin (25-50 units per mL of medium). For detailed decontamination and culturing instructions, consult an appropriate text. Six to eight weeks of incubation may be necessary for evidence of growth of many mycobacteria.

A subcutaneous reservoir can facilitate administration into the cisternal space or lateral ventricle. The role of newer azole antifungal agents, such as voriconazole and posaconazole, in treatment of coccidiomycosis has not been established. When used, these newer azoles should be administered in consultation with experts experienced with their use in treatment of coccidioidomycosis. The duration of antifungal therapy is variable and depends on the site(s) of involvement, clinical response, and mycologic and immunologic test results. Antifungal prophylaxis for solid organ transplant recipients may be considered if they reside in endemic areas and have a prior serologic test result or a history of coccidiomycosis. The overall associated mortality rate was approximately 10%, with most deaths approached 50%. Four distinct genera have been described: Alphacoronavirus, Betacoronavirus, Gammacoronavirus, and Deltacoronavirus. Whether ongoing transmission is going to continue with spread to other regions is not yet clear. Which of these modes are most important remains to be determined, and that droplet and direct contact spread are likely the most common modes of transmission, although evidence of indirect contact spread and aerosol spread also exist. There is no evidence of vertical transmission of of illness, when symptoms and respiratory viral loads are at their highest.

Specimens obtained from the upper and lower respiratory tract are the most appro- the second week of illness when symptoms and viral loads peak; serum samples are most symptoms and presumed corresponding lower viral loads seen in this age group. Any positive test result should be validated by an approved laboratory and must be for other common respiratory pathogens, and epidemiologic data. Cryptococcal meningitis, the most common and serious form of cryptococcal disease, often follows an indolent course. C gattii causes disease in immunocompetent and immunocompromised people, and cases have been reported in children. The incubation period for C neoformans is unknown but likely variable; dissemination often represents reactivation of latent disease acquired previously. In patients with cryptococcal meningitis, antigen test results can be falsely negative when antigen concentrations are low or very high (prozone effect), if infection is caused by unencapsulated strains, or if the patient is less severely immunocompromised. C gattii will grow in the presence of L-canavanine, utilizing the glycine and causing the bromothymol indicator to turn the agar blue. Alternatively, the amphotericin B deoxycholate amphotericin B can be used as a substitute for conventional amphotericin B in children a more prolonged treatment course.

The diagnosis of cryptosporidiosis should be considered in any solid organ transreported in solid organ transplant patients, thought to be related to altered drug metabolism in the small intestine and resulting in acute kidney injury. Oocysts are excreted in feces of an infected host and are transmitted via the fecal-oral route. Cryptosporidium hominis, which predominantly infects people, and Cryptosporidium parvum, which infects people, preweaned calves, and other mammals, are the primary Cryptosporidium species that infect humans. Cases are most frequently reported in children 1 to 4 years of age, followed by those 5 to 9 years of age.

As a result, the Gulf War and Health reports have provided little information that is directly relevant to health conditions that affect Gulf War veterans at excess rates, or their association with Gulf War exposures. Nor do they provide findings on conditions like migraines and seizures, which preliminary information suggests may affect Gulf War veterans at excess rates, in relation to Gulf War exposures. The legislation also directed that determinations be based on scientific evidence provided by both human and animal studies. Most studies that evaluate biological effects of hazardous exposures are done in animals, for ethical reasons. In recent years, a large number of animal studies have identified biological effects of Gulf War exposures and combinations of exposures that were previously unknown. The specific information included in the Gulf War and Health reports is also problematic, in that it appears to reflect a process of reporting selected results from subgroups of studies, rather than integrating and analyzing results from all available research. A very prominent example relates to the limited or complete lack of consideration, in all Gulf War and Health reports, of results from the many epidemiologic studies that have assessed associations between Gulf War exposures and Gulf War multisymptom illness. Another straightforward example comes from Volume 4, which reported the rate of multisymptom illness in Gulf War veterans from just one study, as opposed to the seven studies identified by the present report. The one Gulf War illness prevalence estimate provided was atypical, and substantially lower than all other studies. The finding did not consider basic questions about whether the statistical techniques were capable of identifying syndromes-unique or otherwise. Unfortunately, this conclusion was widely misinterpreted in media reports to indicate that there was no widespread problem associated with multisymptom illness in Gulf War veterans. These limitations are most notably reflected in the selective types of information reviewed and the lack of in-depth analysis of the research literature and scientific questions associated with the health of Gulf War veterans. The reports have particularly fallen short in advancing understanding of associations between Gulf War exposures and Gulf War illness, the most prominent health issue affecting Gulf War veterans. Special Committee and Government Reports 55 Recommendations Despite the brief duration and successful execution of the 1990-1991 Gulf War, 25-32 percent of Gulf War veterans developed the chronic multisymptom condition known as Gulf War illness as a consequence of their Gulf War service. Longitudinal studies indicate that few veterans with Gulf War illness have recovered or significantly improved with time. The Committee gives highest priority to research focused on identifying effective treatments for Gulf War illness. This research should include: Studies that identify and systematically evaluate the effectiveness of currently available treatments used for Gulf War illness or conditions with similarities to Gulf War illness. Research to identify specific pathophysiological mechanisms underlying Gulf War illness that are potentially amenable to treatment interventions. Although it is the most prevalent health problem affecting Gulf War veterans, Gulf War illness is just one of a number of important Gulf War health issues. Completion of current research comparing cancer rates in Gulf War and nondeployed era veterans, and repeated assessment of cancer rates in Gulf War era veterans at regular intervals. Provide current information on overall and cause-specific mortality rates in Gulf War veterans, and update this information, at minimum, at five year intervals. This should include information on mortality in subgroups of Gulf War veterans identified by deployment locations, branch of service, and exposures reported in the National Survey of Gulf War-era Veterans and Their Families. Because of shortcomings and limitations in many epidemiologic studies of Gulf War veterans, the Committee recommends the following principles for collecting and analyzing data on Gulf War illness and the health of Gulf War veterans in ongoing and future studies and, where indicated, for reanalyzing data in studies already completed. Studies of Gulf War veterans should use well-constructed and clearly-described case definitions for Gulf War illness and illness subgroups. The Department of Veterans Affairs has not adhered to requirements set forth by Congress in commissioning the Gulf War and Health series of reports produced by the Institute of Medicine. As a result, these reports have not addressed fundamental questions regarding Gulf War-related health conditions and their relation to Gulf War exposures. As directed by Congress, these reports should address both diagnosed and undiagnosed illnesses affecting Gulf War veterans. Conclusions should be based on findings from the full range of Gulf War epidemiologic studies, animal studies, and other research that provides information on effects of Gulf War-related exposures.

Animals that shed virus through respiratory dissemination or dissemination in urine or feces are far more hazardous than those that do not. The described risk assessment process is also applicable to laboratory operations other than those involving the use of primary agents of human disease. It is true that microbiological studies of animal host-specific pathogens, soil, water, food, feeds, and other natural or manufactured materials, pose com paratively lower risks for the laboratory worker. Nonetheless, microbiologists and other scientists working with such materials may find the practices, containment equ ipm ent, a nd fa cility rec om me nda tions desc ribed in this publication of value in developing operational standards to meet their own a ssess ed nee ds. Some of the most imp ortan t are: t he vir ulenc e, pa thog enic ity, biolo gica l stab ility, route of spread, and communicability of the agent; the nature or function of the laboratory; the procedures and manipulations involving the a gent; the e ndem icity of the age nt; and the availability of effective vaccines or therapeutic measures. Agent summary statements in this section provide guidance for the selection of appropriate biosafety levels. Specific information on labora tory hazard s asso ciated with a particular a gent, and recommendations regarding practical safeguards that can significantly reduce the risk of laboratory-associated diseases, are included. Agent su mm ary statem ents are presen ted for ag ents which meet one or more of the following criteria: the agent is a proven hazard to laboratory personnel working with infectious mate rials. When applicable, recommendations for the use of these products are based on current recommendations of the Public Health Service Advisory Comm ittee on Immunization Practice, and are specifically targeted to at-risk laboratory personnel and others who must work in or enter laboratory areas. These specific recommendations should in no way preclude the routine use of such products as diphtheria-tetanus toxoids, poliovirus vaccine, influenza vaccin e and oth ers, bec ause o f the poten tial risk of co mm unity expos ures irres pective o f any labora tory risks. A ppropria the precautions should be taken in the administration of live 85 Recommended Biosafety Levels For Infectious Agents and Infected Animals attenuated virus vaccines in individuals with altered immunocompetence or other medical condition. Risk assessments and biosafety levels recommended in the agent summary statements presuppose a population of immunocompetent individuals.

Imm uno defic ienc y ma y be he redita ry, con gen ital, or in duc ed by a number of neoplastic or infectious diseases, by therapy, or by radiation. The risk of becoming infected or the consequence of infection may also be influenced by such factors as age, sex, race, pregnancy, surgery. These and other variables must be considered in applying the generic risk assessments of the agent summary statements to specific activities of selected individuals. The biosafety level assigned to an agent is based on the activities typically associated with the growth and manipulation of the quan tities and co ncentra tions of infe ctious ag ents req uired to acc om plish id entific ation or typin g. If ac tivities with c linical m aterials pose a lesser risk to personnel than those activities associated with manipulation of cultures, a lower biosafety level is recommended. On the other hand, if the activities involve large volumes and/or concentrated preparations ("production quantities"), or manipulations which are likely to produce aerosols or which are otherwise intrinsically hazardous, additional personnel precautions and increased levels of primary and secondary containment may be indica ted. Propagation and concentration of infectious agents, as occurs in large-scale fermentations, antigen and vaccine production, and a variety of other commercial and research activities, clearly deal with significant masses of infectious agents that are reasonably considered "production quantities. Therefore, the laboratory director must make an assessment of the activities conducted and select practices, containment equipment, and facilities appropriate to the risk, irrespective of the volume or concentration of agent involved. Occ asio ns w ill arise whe n the labor atory d irecto r sho uld select a biosafety level higher than that recommended. For example, a higher biosafety level may be indicated by the unique nature of the proposed activity. Similarly, a recommended biosafety level may be adapted to compensate for the absence of certain recommended safegu ards.

Occasionally a strain will be encountered that will grow as small brown or greenish glistening colonies. A few strains of Enterobacter aerogenes may develop on this medium, forming raised, mucoid colonies. Enterobacter colonies may exhibit a silvery sheen, appreciably lighter in color than that produced by S. Some members of the coliform group that produce hydrogen sulfide may grow on the medium, giving colonies similar in appearance to S. These coliforms may be readily differentiated because they produce gas from lactose in differential media, for example, Kligler Iron Agar or Triple Sugar Iron Agar. The hydrolysis of urea, demonstrated in Urea Broth or on Urea Agar Base, may be used to identify Proteus sp. Typhi for agglutination or fermentation studies, pick characteristic black colonies from Bismuth Sulfite Agar and subculture them on MacConkey Agar. The purified colonies from MacConkey Agar may then be picked to differential tube media such as Kligler Iron Agar, Triple Sugar Iron Agar or other satisfactory differential media for partial identification. Agglutination tests may be performed from the fresh growth on the differential tube media or from the growth on nutrient agar slants inoculated from the differential media. The growth on the differential tube media may also be used for inoculating carbohydrate media for fermentation studies. Refer to appropriate references for the complete procedure when testing food samples. For additional information about specimen preparation and inoculation of clinical specimens, consult appropriate references. Colonies on Bismuth Sulfite Agar may be contaminated with other viable organisms; therefore, isolated colonies should be subcultured to a less selective medium. Typhi colonies usually develop within 24 hours; however, all plates should be incubated for a total of 48 hours to allow growth of all typhoid strains. Heating this medium for a period longer than necessary to just dissolve the ingredients destroys its selectivity. Typhi surface colony is black and surrounded by a black or brownish-black zone which may be several times the size of the colony. By reflected light, preferably daylight, this zone exhibits a distinctly characteristic metallic sheen. In these heavy growth areas, this organism frequently appears as small light green colonies. This fact emphasizes the importance of inoculating plates so that some areas are sparsely populated with discrete S. Other strains of Salmonella produce black to green colonies with little or no darkening of the surrounding medium. Blood Agar Base (Infusion Agar) Intended Use Blood Agar Base (Infusion Agar), with the addition of sterile blood, is used for the isolation, cultivation and detection of hemolytic activity of streptococci and other fastidious microorganisms. Summary and Explanation Infusion Agar is an all-purpose medium which has been used for many years as a base for the preparation of blood agars. Expected results Colonial morphology on blood agar containing 5% sheep blood is as follows: 1. Hemolytic streptococci may appear as translucent or opaque, grayish, small (1 mm), or large matte or mucoid (2-4 mm) colonies, encircled by a zone of hemolysis. Pneumococci usually appear as very flat, smooth, translucent, grayish and sometimes mucoid colonies surrounded by a narrow zone of "green" (alpha) hemolysis. Staphylococci appear as opaque, white to gold-yellow colonies with or without zones of beta hemolysis. Listeria may be distinguished by their rod shape in stains, and by motility at room temperature. Other organisms representing minimal flora and clinically significant isolates can also be expected to grow on this nonselective formulation. B Principles of the Procedure Infusion from heart muscle, casein peptone and yeast extract provide nitrogen, carbon, amino acids and vitamins in Blood Agar Base.
