Uptake and clearance of Vibrio vulnificus from Gulf Coast Oysters (Crassostrea virginica)
MetadataShow full item record
Oysters collected in late winter, when they were free of Vibrio vulnificus, were exposed in the organism in the laboratory. The oysters effectively concentrated the bacteria from seawater, but when the inoculum was removed, the bacteria were rapidly cleared from the oyster tissues. These results suggest that V. vulnificus may be found in oysters as a result of filtration of the bacteria from seawater rather than active multiplication of the bacteria in the oysters.
