Mycobacterium tuberculosis is representative of which Risk Group?

Mycobacterium tuberculosis is classified as a Risk Group 3 pathogen. This classification is based on the potential of the organism to cause serious disease in a healthy individual, combined with the fact that it can be transmitted via the air, making it a public health concern. Risk Group 3 agents are those that can cause serious or potentially lethal disease through inhalation, and they also typically require special containment measures when being handled or studied in a laboratory setting.

In the case of Mycobacterium tuberculosis, it is known to cause tuberculosis, a significant infectious disease with a global impact. The organism's mode of transmission and the severity of the illness align it with the characteristics of Risk Group 3 pathogens. Proper biosafety procedures, including laboratory containment strategies, are essential to minimize the risk of exposure to such organisms in research and healthcare settings.
