Serotypes of Vibrio cholerae Non-O1 Isolated from Water Supplies for Human Consumption in Campeche, México and their Antibiotic Susceptibility Pattern

the presence of vibrio cholerae non-o1 in water supplies for human consumption in the city of campeche and rural locality of bécal was investigated. v. cholerae non-o1 was detected in 5.9% of the samples obtained in deep pools of campeche. studies conducted in bécal and neighbourhood of morelos in campeche indicated that collected samples harbored v. cholerae non-o1 in 31.5% and 8.7% respectively. there was a particular pattern of distribution of v. cholerae non-o1 serotypes among different studied regions. accordingly, v. cholerae non-o1 serotype o14 predominated in the deep pools of campeche and together with v. cholerae non-o1, o155 were preferentially founds in samples taken from intradomiciliary faucets in the neighbourhood of morelos. samples from bécal predominantly presented the serotype o112. 60% and 53.8% of all studied strains of v. cholerae non-o1 proved to be resistant to ampicillin and carbenicillin. 3.1%, 7.7% and 6.2% presented resistant to doxycycline, trimethoprim-sulfamethoxazole and erythromycin respectively. the study showed the necessity of performing a strong epidemiologic surveillance for emergence and distribution of v. cholerae non-o1
