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 per cent 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 per cent and 8.7 per cent 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 per cent and 53.8 per cent of all studied strains of V. cholerae non-O1 proved to be resistant to amplicillin and carbenicillin. 3.1 per cent, 7.7 per cent and 6.2 per cent presented resistant to doxycycline, trimethroprim-sulfamethoxale and erythromycin respectively. The study showed the necessity of performing a strong epidemiologic surveillance for emergence and distribution of V. cholerae non-O1.
