The isolation and characterization of Vibrio strains were carried out in Yaounde (equatorial area). Well water characteristic focused on water temperature, pH, dissolved oxygen, dissolved CO2, electrical conductivity, suspended solids. Vibrio cholerae, Vibrio fluvialis, Vibrio mimicus, Vibrio parahaemolyticus and Vibrio vulnificus were identified in all four wells investigated. On 50 strains of Vibrio cholerae tested, 8 agglutinated anti O1 serum; 16% therefore belong to serogroup O1. Antimicrobial susceptibility tests showed that most of the environmental strains of Vibrio cholerae studied are sensitive to the majority of the antibiotics tested. The percentage of sensitivity for most of the antibiotics tested is above 50%. CPR (98%); CTX (94%); GM (84%); AMC (82%); DOX (72%); AMX (70%); NAL (52%). There were 34% cases of resistant to nalidixic acid, 26% to amoxicillin, 24% to chloramphenicol, and 18% to doxycycline. The percentage of sensitivity of Vibrio cholerae O1 is always greater than 50% with GM (100%); AMX and DOX (87.5%); CTX and CPR (75%); AMC and NAL (62.5%); CHL (50%). These results contribute to prevention and control of cholera in equatorial region.
