Uta Nursing Microbiology Lab 2; Questions and
Answers % Correct
factors that influence biosafety levels Correct answer-infectivity, severity of disease,
transmissibility, and nature of work conducted in the lab.
microbio labs at uta are considered Correct answer-bsl-2
level 1 description Correct answer-Microbes in BSL-1 labs are not known to consistently
cause disease in healthy adults and present minimal potential hazard to lab workers and the
environment. An example of a microbe that is typically worked with at a BSL-1 is a
nonpathogenic strain of Escherichia coli.
level 2 description Correct answer-Microbes in BSL-2 labs pose moderate hazards to lab
workers and the environment. The microbes are typically indigenous and associated with
diseases of varying severity. An example of a microbe that is typically worked with at a BSL-2
laboratory is Staphylococcus aureus.
level 3 description Correct answer-Microbes in BSL-3 labs can be either indigenous or
exotic, and they can cause serious or potentially lethal disease through respiratory transmission.
Respiratory transmission is the inhalation route of exposure. One example of a microbe that is
typically worked with in a BSL-3 laboratory is Mycobacterium tuberculosis, the bacteria that
causes tuberculosis.
level 4 description Correct answer-Microbes in BSL-4 labs are dangerous and exotic,
posing a high risk of aerosol-transmitted infections. Infections caused by these microbes are
