Abstract |
A total of 205 Vibrio cholerae O1 isolates from recent cholera epidemic in Senegal were analyzed by conventional methods, polymerase chain reaction (PCR) for genes encoding cholera toxin (ctx A), zonula occludens toxin (zot) and accessory cholera enterotoxin (ace), ribotyping and toxinogenotyping. Ribotyping after Bg1 I digestion of total DNA revealed that ribotype B5a, the predominant ribotype of the seventh pandemic in Africa and Asia, was not isolated. A new ribotype designated B27 in our database is predominant and was associated with a new toxinogenotype designated TB31.
