• Abstract: Vibrio cholerae is a native inhabitant of aquatic ecosystems, occurring as free-living bacteria and in association with plankton, especially copepods. Pandemic cholera is traditionally caused by V. cholerae O1 and O139 and in endemics regions as India and Bangladesh, occurrence is typically seasonal. Pathogenicity of V. cholerae is related to the presence of two pathogenicity islands, CTX genetic element and VC pathogenicity island (VPI). Historically, most epidemics begin in coastal areas and the disease is acquired by ingestion of raw seafood or water containing pathogenic V. cholerae. The seventh pandemic occurred in the Americas on 1991 (Peru) and spread rapidly to neighboring countries. In Brazil, V. cholerae O1 El Tor was isolated from clinical and environmental sources during the epidemic. The V. cholerae Brazilian collection of isolates since 1978, showed that environmental isolates were V. cholerae non-O1/non-O139. Seawater (24), copepods (24), oysters (10) and ballast water (99) samples were collected and analyzed. V. cholerae O1 was found to be present in seven ballast water samples but ballast water contains very large numbers of copepods. Ballast water may transport potentially pathogenic microorganisms and could cause an increase in the population of existing pathogenic microorganisms. We present a total DNA extraction and multiplex PCR method for aquatic ecosystem samples and a method to count viable V. cholerae to estimate microbiological riskfor human health and also for the aquatic ecosystem
