[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%. The rose Bengale and immunofluorescence tests combination permits complete detection of positive sera. These results suggest the existence of human brucellosis in Bénin and shows the necessity of a national control programme adapted to the socio-economic problems of this country.

[Fosfomycin resistance in Staphylococcus saprophyticus and other species of coagulase-negative staphylococci].

Susceptibility of 121 isolates of coagulase-negative staphylococci to two antimicrobial agents, novobiocin and fosfomycin, was determined using the agar dilution method. Isolates included 45 strains of Staphylococcus saprophyticus, 26 strains of S. cohnii and S. xylosus, 24 strains of S. epidermidis and 26 strains of S. hominis, S. capitis, S. warneri and S. auricularis . The minimal inhibitory concentration average of fosfomycin for S. saprophyticus differed (p less than 0.001) from that other for novobiocin-resistant staphylococci (S. cohnii and S. xylosus) and for S. epidermidis (p less than 0.001). Out of 45 isolates of S. saprophyticus, 42 were resistant to fosfomycin. The results were very heterogeneous with regard to fosfomycin for all of the other coagulase-negative staphylococci. Resistance to fosfomycin, like resistance to novobiocin, could be used as a presumptive test for the identification of S. saprophyticus.
