First report of a mycolactone-producing Mycobacterium infection in fish agriculture in Belgium.

In the past few years, a mycolactone-producing subgroup of the Mycobacterium marinum complex has been identified and analyzed. These IS2404-positive species cause pathology in frogs and fish. A recently isolated mycobacterial strain from a fish in Belgium was analyzed using a variety of molecular methods and the results were identical to those obtained from a mycolactone-producing M. marinum from Israel.
