The presence of Vibrio cholerae non-O1 in water supplies for human
consumption in the city of Campeche and rural locality of Becal was
investigated. V. cholerae non-O1 was detected in 5.9% of the samples
obtained in deep pools of Campeche. Studies conducted in Becal 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
Becal 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.
