Where is Mycobacterium Abscessus found?

Mycobacterium abscessus is a bacterium distantly related to the ones that cause tuberculosis and leprosy. It is part of a group known as rapidly growing mycobacteria and is found in water, soil, and dust. It has been known to contaminate medications and products, including medical devices.

Is Mycobacterium chelonae contagious?

Patients with M chelonae infections are not contagious and should not be isolated.

Do mycobacteria have a cell wall?

The distinguishing feature of mycobacteria, the complex cell wall, is a well-recognized drug target. The cell wall is common to all bacteria, both Gram-positive and Gram-negative, but can have vast differences in terms of the biochemical and structural features.

What does M fortuitum cause?

It is uncommon for this condition to cause lung disease, but Mycobacterium fortuitum infection can lead to skin disease, osteomyelitis (inflammation of the bone), joint infections, and eye disease .

Is Mycobacterium fortuitum aerobic or anaerobic?

Mycobacteria are aerobic, non-motile, acid-fast bacilli, in that they have the ability to retain dyes after washing of alcohol decolorization.

How does Mycobacterium chelonae spread?

Trauma or injection – Accidental or surgical trauma, particularly puncture wounds (eg, tattoos, acupuncture, injection sites) Disseminated disease – Immunosuppression, immune defects, and cytotoxic chemotherapy. Lung disease -Bronchiectasis, cystic fibrosis. Tattoo ink and contaminated skin marking solutions.

Is Mycobacterium chelonae fatal?

Mycobacterium chelonae is a rapidly growing mycobacteria that commonly affects the skin. In an immunocompromised host, the infection can disseminate haematogenously with a fatal outcome.
