Bacillus anthracis, a gram-positive, non-hemolytic, and non-motile bacillus, is the etiologic agent of anthrax, an acute bacterial disease of mammals, including humans. Like all members of the genus Bacillus, under adverse conditions B. anthracis has the ability to produce spores that allow the organism to persist for long periods until the return of more favorable conditions.
Coxiella burnetii is the etiologic agent of Q fever. C. burnetii is a bacterial obligate intracellular pathogen that undergoes its developmental cycle within an acidic vacuolar compartment exhibiting many characteristics of a phagolysosome.
Blastomyces dermatitidis is a dimorphic fungal pathogen existing in nature and in laboratory cultures at room temperature as a filamentous mold with asexual spores (conidia) that are the infectious particles; these convert to large budding yeasts under the appropriate culture conditions in vitro at 37°C and in the parasitic phase in vivo in warm-blooded animals. The sexual stage is an Ascomycete with infectious ascospores.
Additional details about occupationally-acquired cases of parasitic infections, as well as recommendations for post exposure management, are provided elsewhere.1-3 Effective antimicrobial treatment is available for most parasitic infections.4 Immunocompromised persons should receive individualized counseling (specific to host and parasite factors) from their personal healthcare provider and their employer about the potential risks associated with working with live organisms.
Hantaviruses are negative sense RNA viruses belonging to the genus Hantavirus within the family Bunyaviridae. The natural hosts of hantaviruses are rodent species and they occur worldwide. Hantavirus pulmonary syndrome (HPS) is a severe disease caused by hantaviruses such as Sin Nombre virus or Andes virus whose hosts are rodents in the sub familySigmodontinae.
Seven immunologically distinct serotypes of Botulinum neurotoxin (BoNT) have been isolated (A, B, C1, D, E, F and G). Each BoNT holotoxin is a disulfide-bonded heterodimer composed of a zinc metallo-protease "light chain" (approximately 50 kD) and a receptor binding "heavy chain" (approximately 100 kD).

Planning and implementation of control practices for the prevention of laboratory-acquired infections and for the protection of the general environment are to be included in all research programs involving biohazardous agents.
The standards described provide guidance to all researchers and animal handlers administering chemical agents, whether they be pharmaceutical or non-pharmaceutical grade.
The CDC and USDA have designated certain biological agents and toxins as Select Agents, because they have the potential to pose a severe threat to public, animal or plant health, or to animal or plant products. These materials require federal registration and approval to receive, posses, or transfer them.
This letter is to advise any interested parties that the North Carolina Association of Insurance Agents is recognized as Agent of Record and has authority to quote, secure, and bind policies of property, liability, casualty, accident and health insurance for the State of North Carolina and its related agencies.
The purpose of this standard is to ensure that any proposed neuromuscular blocking drugs are properly utilized in conjunction with appropriate analgesics and anesthetics and users are aware of autonomic nervous system changes that can be indicator of pain related to an inadequate depth of anesthesia.
Transmissible spongiform encephalopathies (TSE) or prion diseases are neurodegenerative diseases which affect humans and a variety of domestic and wild animal species (Tables 1 and 2).1,2 A central biochemical feature of prion diseases is the conversion of normal prion protein (PrP) to an abnormal, misfolded, pathogenic isoform designated PrPSc (named for "scrapie," the prototypic prion disease).
Viral vectors have become a staple of the molecular biology community. As such, it is important to understand the origins of these tools and potential implications of their use. The most commonly used viral vectors are outlined below. Included is information on virology, laboratory hazards, biological safety containment procedures, Personal Protective Equipment (PPE), disinfection, and animal use procedures.
In 1979, the American Committee on Arthropod-Borne Viruses (ACAV) Subcommittee on Arbovirus Laboratory Safety (SALS) first provided biosafety recommendations for each of the 424 viruses then registered in the International Catalogue of Arboviruses, including Certain Other Viruses of Vertebrates.
