A retrospective survey was carried out on the epidemiological monitoring of
the isolation incidence of Mycobacterium marinum in 21 laboratories, in an
attempt to gain an insight into the frequency of its isolation in Spain. F
rom 1991 to 1998, 39 cases (22 male and 17 female) of bacteriologically con
firmed M. marinum infection were accumulated. The majority of the cases (35
) were fish related. The clinical presentation usually suggested sporotrich
osis, with the majority of skin eruptions appearing on the hand (32 cases).
For treatment, minocycline was recommended as the drug of choice in 12 cas
es, rifampicin in eight cases and clarithromycin and ethambutol in seven ca
ses.
