Mycobacterium fortuitum (my-co-bac-te-ri-um for-tu-i-tum) is a nontuberculous mycobacterium (NTM), part of the Mycobacterium genus, known for causing a variety of infections in humans.

Etymology

The name Mycobacterium fortuitum is derived from the Latin mykes (fungus) and bakterion (small rod), referring to its rod-like shape, and fortuitum (accidental), indicating its opportunistic nature.

Description

Mycobacterium fortuitum is a rapidly growing mycobacterium (RGM) that is found in the environment, including water and soil. It is acid-fast, non-motile, and does not form spores. It is capable of causing a variety of infections, including skin and soft tissue infections, pulmonary infections, and disseminated disease.

Infections

Infections with Mycobacterium fortuitum can occur in both immunocompetent and immunocompromised individuals. The bacterium can enter the body through breaks in the skin, leading to localized infections. It can also cause pulmonary infections, particularly in individuals with underlying lung disease. In rare cases, it can cause disseminated disease, affecting multiple organs.

Treatment

Treatment of Mycobacterium fortuitum infections typically involves a combination of antibiotics, including macrolides, quinolones, and aminoglycosides. The specific regimen is often tailored to the individual patient, based on the severity of the infection and the patient's overall health.
