Abstract

Vibrio spp are gram-negative, halophilic bacteria that naturally occur in both shallow coastal waters and parts of the deepest oceans and are a known human pathogen. There have not been extensive studies that analyze an oil spill as an environmental stressor to vibrios. If there were to be an increase in the pathogenicity of vibrios it would be a cause for human health concern. The purpose of the two studies presented was to determine changes in the pathogenicity of V. parahaemolyticus pathogenicity and the vibrio community, with respect to V. cholera, V. parahaemolyticus, and V. vulnificus. The results showed that there was an insignificant change in V. parahaemolyticus pathogenicity, and there was not a significant trend in the species composition of the vibrio community when interacting with oil. Even though the results did not show statistically significant or consistent trends of both studies, the study was an innovative evaluation of the vibrio community and various oil concentration effects thereon.
