Description
Water and sediment samples monthly collected from Arcachon Bay (Gironde, France) were examined during three years for the presence of marine vibrios. V. cholerae serotype 01 was never detected. On the other hand, the Eyre River and mouth contain non-agglutinating V. cholerae (127 strains) principally in water. The low temperatures slow their development down without stopping it completely. V. parahaemolyticus (257 strains) present in the same areas is particularly isolated from water when the aquatic medium temperature rises to 15 degree C. V. alginolyticus (638 strains) settles the whole Bay, except the river, in any season. The low temperatures promote growth of V. metschnikovii (203 strains) very tolerant towards salinity. V. anguillarum (46 strains) shows a similar comportment to V. parahaemolyticus . No correlation between incidence of fecal coliforms and vibrio could be detected.
