Virulence Potential

ABSTRACTThe prevalence ofVibrio vulnificuson the external surfaces of fish from the northern Gulf of Mexico was determined in this study. A collection of 242 fish comprising 28 species was analyzed during the course of 12 sampling trips over a 16-month period. The prevalence ofV. vulnificuswas 37% but increased up to 69% in summer. A positive correlation was found between the percentages ofV. vulnificus-positive fish and water temperatures, while salinity andV. vulnificus-positive fish prevalence were inversely correlated. A general lineal model (percentV. vulnificus-positive fish = 0.5930 − 0.02818 × salinity + 0.01406 × water temperature) was applied to best fit the data. Analysis of the population structure was carried out using 244 isolates recovered from fish. Ascription to 16S rRNA gene types indicated that 157 isolates were type A (62%), 72 (29%) were type B, and 22 (9%) were type AB. The percentage of type B isolates, considered to have greater virulence potential, was higher than that previously reported in oyster samples from the northern Gulf of Mexico. Amplified fragment length polymorphism (AFLP) was used to resolve the genetic diversity within the species. One hundred twenty-one unique AFLP profiles were found among all analyzed isolates, resulting in a calculated Simpson's index of diversity of 0.991. AFLP profiles were not grouped on the basis of collection date, fish species, temperature, or salinity, but isolates were clustered into two main groups that correlated precisely with 16S rRNA gene type. The population ofV. vulnificusassociated with fishes from the northern Gulf of Mexico is heterogeneous and includes strains of great virulence potential.
