''Mycobacteria'' infect many species of '''freshwater, saltwater''' and '''aquarium fish'''. The latter species  are more likely to show a higher incidence of disease due to the chronicity of the disease and increased ages of aquarium kept fish compared to commercial fish.   

''Mycobacteria'' infect many species of '''freshwater, saltwater''' and '''aquarium fish'''. The latter species  are more likely to show a higher incidence of disease due to the chronicity of the disease and increased ages of aquarium kept fish compared to commercial fish.   

Some ''mycobacteria'' found in fish species are '''zoonotic''' and '''''M. marinum''''' and '''''M. Fortuitum''''', can cause '''skin disease in humans'''.  Outbreaks have been reported from '''cutaneous abrasions''' and '''exposure to contaminated swimming pool water'''.  ''M. fortuitum'' has been cultured from patients with pulmonary disease and local abscesses (Cruz, 1938) Cruz JC, 1938. Mycobacterium fortuitum um Novo Bacilo Acidoresistente Patogenico para o Homen. Acta Medical Rio de Janeiro, 1:297.and M. chelonei has been isolated from heterograph heart-valve transplants, synovial fluid and muscle (Blacklock and Dawson, 1979; Blacklock ZM, Dawson DJ, 1979.
