current epidemiology of human plague in madagascar.from 1996 to 1998, 5,965 patients with suspected plague were identified in 38 districts of madagascar (40% of the total population are exposed). using standard bacteriology, 917 of them were confirmed or presumptive (c + p) cases. however, more than 2,000 plague cases could be estimated using f1 antigen assay. two out of the 711 yersinia pestis isolates tested were resistant to chloramphenicol and to ampicillin (both isolates found in the harbour of mahajanga). urban plague (mahajanga harbour an ...200010717537
