[Activities in the Senegalese National Center of Enterobacteria in 1980, 1981 and 1982].

1,589 strains of Salmonella and 192 strains of Shigella have been studied in the Senegalese National Center of Enterobacteria during 1980, 1981 and 1982. By the side of typhoid fever which remains the most frequent salmonellosis in Senegal (51.4% of human isolates), hospital-acquired salmonellosis have to be separately dealt with ( S. ordonez in 1980, S. chester in 1981, S. ibadan in 1982), characterized by high infantile mortality and constant multiple resistance to antibiotics. A country investigation showed the carriage of numerous and different serotypes in men and animals. Shigella strains isolated in Senegal keep yearly a similar antigenic distribution. On the other hand, occurrence of resistant strains (to ampicillin, tetracycline, trimethoprim -sulfamethoxazole) seems to be increasing.
