Isolation of Vibrio cholerae serotype O1 from the eastern oyster, Crassostrea virginica.
Two strains of Vibrio cholerae serotype O1 Inaba were isolated from eastern oysters, Crassostrea virginica, collected from estuarine waters in Florida during April 1980. The oyster meats and waters from which the oysters were collected had low fecal coliform counts, and the area had no prior evidence of sewage contamination.
متن کاملOccurrence and characteristics of agglutination of Vibrio cholerae by serum from the eastern oyster, Crassostrea virginica.
Cell-free hemolymph (serum) of the eastern oyster, Crassostrea virginica, agglutinated Vibrio cholerae, including all O1 serovars and biovars. Seventy-nine other strains of bacteria, including 14 genera and 26 species, were not agglutinated. The A, B, and C factors of O1 antigen were not involved in agglutination. Bacterial agglutinating (BA) activity was demonstrated for oysters inhabiting dif...
متن کاملPersistence of Vibrio vulnificus in tissues of Gulf Coast oysters, Crassostrea virginica, exposed to seawater disinfected with UV light.
Vibrio vulnificus is an estuarine bacterium which can cause opportunistic infections in humans consuming raw Gulf Coast oysters, Crassostrea virginica. Although V. vulnificus is known as a ubiquitous organism in the Gulf of Mexico, its ecological relationship with C. virginica has not been adequately defined. The objective of the present study was to test the hypothesis that V. vulnificus is a ...
متن کاملElevated temperature method for recovery of Vibrio cholerae from oysters (Crassostrea gigas).
Of 222 Vibrio cholerae isolates from diverse clinical and environmental sources, 219 produced visible growth in alkaline peptone broth when incubated overnight at 42 degrees C. In field trials conducted to compare enrichment at incubation temperatures of 42 and 35 degrees C, significantly higher rates of isolation (P less than 0.05) and recovery (P less than 0.01) of V. cholerae from oysters we...
متن کاملDevelopment and validation of a predictive model for the growth of Vibrio vulnificus in postharvest shellstock oysters.
Postharvest growth of Vibrio vulnificus in oysters can increase risk of human infection. Unfortunately, limited information is available regarding V. vulnificus growth and survival patterns over a wide range of storage temperatures in oysters harvested from different estuaries and in different oyster species. In this study, we developed a predictive model for V. vulnificus growth in Eastern oys...
