Biological Materials
BSL1- defined & well characterized strains of viable microorganism NOT known to cause disease in healthy adults. Examples: Bacillus subtilis and infectious Canine hepatitis.
BSL2 - a broad spectrum of indigenous moderate -risk agents present in the community and associated with human diseases of varying severity. With good technique, these agents can be used safely on open benchtop when potential for aerosolization or splashing is low. Examples: Hepatitis B virus, Salmonellae spp, and Toxoplasma spp. Hazards are mainly due to the potential for needlestick (autoinnoculation) or ingestion exposure.
