What type of infection is tuberculosis?

Tuberculosis is classified as a bacterial infection because it is caused by the bacterium Mycobacterium tuberculosis. This pathogen is known for its ability to survive in low oxygen environments, which typically characterizes the lungs and other parts of the body where it infects individuals. The infection primarily affects the respiratory system but can also spread to other areas, such as the kidneys, spine, and brain.

Understanding that tuberculosis is bacterial highlights the different treatment approaches compared to viral, fungal, or parasitic infections. For tuberculosis, the main treatment involves a lengthy course of antibiotics specifically designed to combat bacterial pathogens, underscoring the importance of recognizing the type of infection in relation to appropriate medical response and management.
