What is the prognosis for those infected with Mycobacterium marinum?
The prognosis is excellent for a complete cure with a proper, full course of oral antibiotics and good medical follow-up with your physician. There are no long-term problems after treatment.
How do I find a specialist?
Specialists including dermatologists, infectious disease physicians, and rheumatologists may have additional expertise in the diagnosis and treatment of this rare disorder.
What are possible complications from Mycobacterium marinum?
M. marinum infections are usually localized and typically do not spread past the skin in healthy people. Most patients with a normal immune system don't experience other complications. However, undetected or untreated, the infection may progress and cause deeper and more longstanding infections. Patients with an impaired immune system (immunocompromised) may be much more prone to serious complications such as spread of infections to involve the bone marrow and internal organs.
Some rare potential problems include infection of the underlying bone called osteomyelitis, infection of the deep muscle tendons called tenosynovitis, inflammation of the joints called arthritis, and widespread bodily infections called disseminated disease.
Do fish get infected with Mycobacterium marinum?
Yes. There are probably two different types of M. marinum. One type only causes a longstanding (chronic) progressive disease in fish without affecting humans. The second type, which can infect humans, seems to cause a deadly sudden illness in fish.
