Question

There is an outbreak of an infectious disease. This disease causes non-life-threatening diarrhea and epidemiologists determine it is from eating at a particular restaurant. Subsequent analysis concludes that it is, in fact, a foodborne infection, only transmitted by ingestion. Fortunately, this illness seems to be controlled by standard antibiotics, and the outbreak is quickly contained. Working in a clinical microbiology lab, you isolate the causative agent, a bacterium, from a stool sample. In which laboratory biosafety level would you place it? Group of answer choices

Biosafety Level 0

Biosafety Level 1

Biosafety Level 2

Biosafety Level 3

Biosafety Level 4

Biosafety Level 5

Biosafety Level A

Answer 1

Answer :

Correct choice is C

BIOSAFETY LEVEL 2

Biosafety level I - defined organism - not known to cause disease in healthy adults - eg : lactobacillus.

Biosafety level II - moderate risk agents present in community - disease of varying severity - eg: salmonella, herpes simplex etc

Biosafety level III - indigenous or exotic agents, aerosol transmission, serious potentially fatal infection. Eg: brucella, west nile fever.

Biosafety level IV - dangerous or exotic high risk agents, life threatening disease eg : ebola, marburg etc

Here organism is pathogenic. So not level 1. It causes moderate risk infection. There is treatment. So it better fits to biosafety level II.
