Interpretive Summary:

Technical Abstract: This study examined the response of Vibrio vulnificus to incubation at 13 and 4ºC. It focused on changes in protein expression using one and two dimensional gel electrophoresis. Although different proteins were expressed following cooler temperature exposure no major cold shock protein was identified. As hypothesized, longer incubation times at 13ºC resulted in increased variations. Proteins expressed at the cooler temperature were only transiently expressed, classical of stress responses. These preliminary results suggest there is a cold shock response active in V. vulnificus that requires further investigation in order to properly evaluate and alter the general management practices for collection and processing of the Eastern Oyster, Crassostrea virginica, from the Gulf of Mexico.
