Each objective below describes a competency you will apply at the microbiology bench, not rote definitions in isolation.

  • Summarize BSL-1 through BSL-4 at an introductory level, including typical agent risk framing
  • Explain that biosafety practices follow institutional adoption of BMBL guidance and local risk assessment, not memorized agent lists alone
  • Recognize that routine clinical microbiology work is commonly performed at BSL-2, with escalation pathways for higher-risk agents
