“…In contrast, V. alginolyticus, V. parahaemolyticus and V. vulnificus strongly responded to increases in water temperature, and followed distinct seasonal cycles in terms of isolation frequency and abundance, corresponding to earlier observations on Vibrio ecology [19,60,61]. Water temperature ranged between 0 and 26.5°C throughout the study, and was shown to be the crucial factor governing the occurrence and abundance of these three species in the study area, both in correlation analyses and regression models.…”

The number of reported Vibrio-related wound infections associated with recreational bathing in Northern Europe has increased within the last decades. In order to study the health risk from potentially pathogenic Vibrio spp. in the central Wadden Sea, the seasonal and spatial distribution of Vibrio vulnificus, Vibrio parahaemolyticus, Vibrio alginolyticus and Vibrio cholerae were investigated at ten recreational beaches in this area over a 2-year period. V. alginolyticus and V. parahaemolyticus were found to be omnipresent all year round in the study area, while V. vulnificus occurrence was restricted to summer months in the estuaries of the rivers Ems and Weser. Multiple linear regression models revealed that water temperature is the most important determinant of Vibrio spp. occurrence in the area. Differentiated regression models showed a species-specific response to water temperature and revealed a particularly strong effect of even minor temperature increases on the probability of detecting V. vulnificus in summer. In sediments, Vibrio spp. concentrations were up to three orders of magnitude higher than in water. Also, V. alginolyticus and V. parahaemolyticus were found to be less susceptible towards winter temperatures in the benthic environment than in the water, indicating an important role of sediments for Vibrio ecology. While only a very small percentage of tested V. parahaemolyticus proved to be potentially pathogenic, the presence of V. vulnificus during the summer months should be regarded with care.

“…While an estuarine environment represents an ideal setting for the survival and persistence of V. cholerae, cholera has also become endemic in arid and inland areas of Africa [9] such as Burkina Faso [10]. V. cholerae strains of non-O1/non-O139 serotypes can cause diarrheal symptoms and extraintestinal infections in humans [11]. Therefore, environmental monitoring for the presence of V. cholerae and other Vibrio species with pathogenic potential is important, as it can identify the potential sources of infections.…”

Introduction: Vibrio cholerae is a human pathogen and natural inhabitant of aquatic environments. In this study, we surveyed the occurrence of V. cholerae in fish harvested from a reservoir that receives discharges from the population in Ouagadougou through several channels. Methodology: A total of 238 fish and 80 water samples were analyzed for the presence of V. cholerae. Results: Altogether, 13 V. cholerae strains were isolated. They were all identified as non-O1/non-O139 V. cholerae without the ctxA gene. The strains were mostly susceptible to the antimicrobials tested. Conclusion: Although no strains of epidemic V. cholerae serotypes were encountered, it is important to monitor the microbiological quality of this extensively used water resource and its fish.

“…Vibrio spp. have been demonstrated in various tissues of molluscan bivalves such as clams, oysters and mussels to levels sometimes 100 times that of the overlying water 21 . Wang et al 22 demonstrated that V. parahaemolyticus was accumulated in digestive glands, gills, adductor muscle and mantle cilia of oysters after artificial inoculation.…”

Infection by Vibrio parahaemolyticus is established if seafood contaminated with pathogenic strains of this bacterium at a sufficiently high dose is consumed. We reported recently that V. parahaemolyticus isolates from 67% of patients constituted a homogeneous population of a pathogenic strain and a heterogeneous population of V. parahaemolyticus varying in the serotype and/or the virulence gene profile found in 33% of the patients. To assess the possibility that this result was due to the dominant presence of a homogeneous strain of V. parahaemolyticus in shellfish, we enumerated and characterized V. parahaemolyticus in shellfish samples including three kinds of molluscan bivalves. Using CHROMagar Vibrio isolation medium, presumed total Vibrio strains and presumed V. parahaemolyticus in each of 52 shellfish samples were enumerated. The highest numbers of presumed total Vibrio strains and presumed V. parahaemolyticus were detected in bloody clam and mussel, respectively. There was no correlation between the number of presumed total Vibrio strains and that of presumed V. parahaemolyticus. Five to ten strains of V. parahaemolyticus isolated from each shellfish sample were characterized. Virulence genes (tdh and trh) could be detected in none of the isolated strains. Diversities in the serotype and DNA fingerprints were confirmed among the isolated strains from a single shellfish sample representing six different shellfish groups. We therefore conclude that most of the single shellfish harbour a pathogenic strain-bearing heterogeneous population of V. parahaemolyticus and the concentrations of pathogenic strains are low.
