[Human brucellosis in Benin: results of a serological survey among exposed workers].

A serological survey was carried out in Bénin in order to assess the rate of brucellosis infection among exposed workers (workers in slaughtering-houses and breeders). 221 sera were tested with rose Bengale test, Wright sero-agglutination test, indirect immunofluorescence test and counter-immuno electrophoresis (brucelline). The percentage of positive sera among exposed workers is 17,7%.
