What is the classification of Mycobacterium chelonae in the context of these notes?

• A. Virus
• B. Bacteria
• C. Fungus
• D. Parasite

Answer: (B)

Mycobacterium chelonae is a bacterium. It belongs to the mycobacteria, which are single-celled organisms with a waxy cell wall that makes them acid-fast. This species is a rapid-growing non-tuberculous mycobacterium and can cause skin infections if it enters through breaks in the skin, such as during tattooing or piercing. Recognizing it as bacteria (not a virus, fungus, or parasite) matters for infection control: disinfection and sterilization plans must be effective against bacteria, including mycobacteria, rather than relying on measures that only target other types of pathogens.
