The agents listed by the Centers for disease Control and Prevention (CDC) are those biological agents known to infect humans as well as select animal agents that may pose theoretical risks if inoculated into humans. In general, the four biosafety levels (BSLs) correspond directly to the four risk groups of microorganisms. The agents of minimal hazard are Biosafety Level 1 (BSL-1), with the most dangerous microorganisms at Biosafety Level 4 (BSL4). The following descriptions were taken from Biosafety in Microbiological and Biomedical Laboratories 5th Edition.
The following is a list of the biological agents used at Tusculum University along with their Biosafety Level (BSL).
BSL 1 AGENTS
BSL 2 AGENTS
Each BSL has recommended practices, barriers, equipment, and facility requirements that must be in place to be able to use these organisms. A table summarizing these requirements can be found below.
