[Tropical fish salesmen's knowledge and behaviour concerning "fish tank granuloma"].
OBJECTIVE
Mycobacterium marinum is responsible for "fish tank granuloma", a chronic and sometimes disabling skin infection, which in France would be the most frequent "atypical" cutaneous mycobacteriosis. Tropical fish salesmen are concerned about this disease because they might sell contaminated fish and be infected themselves. A review of the literature indicated that one quarter of the patients were aquarium workers. This original study tested the salesmen's knowledge and behaviour regarding "fish tank granuloma".


METHODS
This national study consisted in an anonymous questionnaire with 24 questions.


RESULTS
Among forty salesmen, six of them (15 p. 100) knew this human disease well. Thirty (75 p. 100) ignored it. Among the few salesmen (22.5 p. 100) who had studied to become aquarium workers, only one third were taught about Mycobacterium marinum. Eight salesmen (20 p. 100) were concerned about the human disease: three of them were personally infected and five others had known infected colleagues or purchasers. Most of the aquarium workers immersed their hands without gloves in the fish tanks every day. Only a few destroyed all the fishes from a contaminated tank.


CONCLUSIONS
Most of the tropical fish salesmen ignored "fish tank granuloma" although 20 p. 100 of them were concerned. This chronic disease, sometimes disabling, should be better known by aquarium salesmen. The national tropical fish salesmen were informed of the results of this study.
