Question

Which biosafety level is appropriate for research with microbes or infectious agents that pose moderate risk to laboratory workers and the community, and are typically indigenous?

a) Biosafety Level 1
b) Biosafety Level 2
c) Biosafety Level 3
d) Biosafety Level 4

Answer 1

The appropriate biosafety level for research with moderate-risk microbes or infectious agents is Biosafety Level 2 (BSL-2). BSL-2 labs require additional precautions beyond BSL-1 and include restricted access and the use of PPE.

Step-by-step explanation:

The appropriate biosafety level for research with microbes or infectious agents that pose a moderate risk to laboratory workers and the community, and are typically indigenous, is Biosafety Level 2 (BSL-2). BSL-2 laboratories require additional precautions beyond those of BSL-1, including restricted access, required personal protective equipment (PPE), and the use of biological safety cabinets for procedures that may disperse agents through the air. Examples of agents classified as BSL-2 include Staphylococcus aureus, Salmonella spp., and hepatitis, mumps, and measles viruses.
