Mycobacterium chelonae

Mycobacterium chelonae is a rapidly growing species of Mycobacterium that is commonly found in the environment, including soil and water. It is a member of the Mycobacterium fortuitum complex and is known to cause a variety of infections in humans, particularly in those with compromised immune systems.

Classification

Mycobacterium chelonae belongs to the genus Mycobacterium, a group of bacteria that includes over 150 species. It is part of the Mycobacterium fortuitum complex, a group of rapidly growing, non-tuberculous mycobacteria.

Epidemiology

Mycobacterium chelonae is widely distributed in the environment and can be found in soil, dust, water, and biofilms. It is not typically associated with animals, but can cause disease in humans, particularly in those with compromised immune systems.

Clinical significance

Mycobacterium chelonae is an opportunistic pathogen that can cause a variety of infections in humans. These can range from skin and soft tissue infections to more serious conditions such as lung disease and disseminated disease. Infections are often associated with trauma or surgery, and can be difficult to treat due to the organism's inherent resistance to many antibiotics.

Treatment

Treatment of Mycobacterium chelonae infections can be challenging due to the organism's resistance to many commonly used antibiotics. However, some drugs, such as clarithromycin, have been shown to be effective. Treatment often involves a combination of antibiotics and may need to be continued for several months.
