Question

Quizplus · Accepted Answer

The bacterial load necessary to cause infection is not a criterion used to categorize biosafety levels. Biosafety levels are primarily determined by factors such as the organism's ability to cause serious illness, its mode of transmission, and the availability of treatments or vaccines, rather than the quantity of bacteria required to cause infection.
