QUINONES-RAMIREZ, Elsa Irma et al. Presencia de los géneros Vibrio y Salmonella, y detección de coliformes fecales en almejas del Golfo de México. Hidrobiológica [online]. 2000, vol.10, n.2, pp.131-138. ISSN 0188-8897.

In general, because the areas chosen for growing them and because the way they feed, mollusks are important vectors in the transmission of several diseases to humans. Among these diseases is cholera. In this study isolation and identification of Salmonella spp.; Vibrio cholerae, and fecal coliforms were carried in 260 clams collected during a year from the northern coast of Veracruz state, Gulf of Mexico. Baseline methods included those recommended by the Bacteriological Analytic Manual (BAM-FDA). Vibrio cholerae 01 was found in 7% of the samples, Salmonella spp. in 9%, and Vibrio no 01 in 22%. Besides, fecal coliforms were detected in all samples (100%). Summer was the time with higher presence of all the microorganisms; even they existed all year around. Pathogenic bacteria in clams make their consumption risky to public health. The detection of fecal coliforms in water shows the existence of non-well planned human settlements and activities around water reservoirs in Atlantic coast of Mexico.
