[Cutaneous mycobacteriosis of aquaria. A disease transmitted from fish to man]

The Authors refer about one case of cutaneous infection from Mycobacterium marinum transmitted to man from tropical fishes of a fish tank. The Authors describe the lesions produced by mycobacterium in man and in fish, as well as the relevant hystological findings and the microbiological enquiries carried out for isolation and typing. The possibility of direct transmission of a tubercular infection from fish to man has been demonstrated. The Authors think it to be useful a careful sanitary control on the ichthyc fauna destined to domestic fish tanks.
