ABSTRACT

Oysters are considered a see fruit or major economical and social importance in Cartagena de Indias, due to the impact that they have in the hotel and tourism industry. However, oysters have been hold responsible as possible significant vectors for food poisoning. to test oysters (Crassostrea rhizophorae) capture in la Ciénaga de la Virgen for contamination with Vibrio, in order to put the appropriated local costumer health care authorities, under alert. 67 Oysters, belonging to 5 strategic points through the Ciénaga de la Virgen (Pantalla metálica, Mangles cielo mar sector, Espolones, Mangles airport sector y Mangles oriental sector) were analyzed, between February and April 2006. Culture mediums and Biochemical test was used for Vibrio´s isolation and identification. the predominant Vibrio´s species were V. alginolyticus (23%), V fluvialis (20%), V. parahaemolyticus (10%), V. carchariae and V mimicus (13%), V. vulnificus, cincimatiensis and V. campbelli (7%). The sampling point with the highest number of Vibrio isolation was Mangles, cielo mar sector, which also contributed with 30% of the total of all species isolated although the difference was of no statistical significance due to their homogenous distribution. 100% of the sampling points showed cloudy water due to the presence of organic matter in suspension and visible solid waste, Thus, Factors influencing Vibrios proliferation on oysters maybe related with the Ciénaga characteristics.
