[Bacteriology of shigella isolated in a tropical zone CHU]

From 1981 to 1991, five hundred eighty one Shigella's strains were isolated in the Laboratories of the CHU Fann of Dakar. They represent 24.8 per cent of enteropathogen agents and 4.3 per cent of diarrhoeae causative agents. Shigella flexneri was predominant (71%), following by Shigella dysenteriae (14.5%), Shigella sonnei (11.4%) and Shigella boydii (2.5%). In pediatric hospital 90 per cent of strains were isolated between 1 and 5 years age; in adults, the pic was found from 20 to 30 years. Five of the 13 tested antibiotics had inhibited 89 to 96 per cent of strains. The isolation of multiresistant strains will be in rapport with the antibiotic resistant plasmide portage.
