| incidence of vibrio parahaemolyticus in u.s. coastal waters and oysters. | oyster and seawater samples were collected seasonally from may 1984 through april 1985 from shellfish-growing areas in washington, california, texas, louisiana, alabama, florida, south carolina, virginia, and rhode island which had been designated as approved or prohibited by the national shellfish sanitation program. fecal coliforms counts, aerobic plate counts, and vibrio parahaemolyticus densities were determined for the samples. mean v. parahaemolyticus density was more than 100 times greate ... | 1990 | 2403249 |
| spectrum of vibrio infections in a gulf coast community. | infection with vibrio species was diagnosed in 23 patients over a 10-year period in a gulf coast community. species isolated were vibrio vulnificus, v. cholerae, v. parahaemolyticus, and v. alginolyticus. clinical presentations included diarrhea, wound infection, and bacteremia. gastrointestinal tract infection was infrequently diagnosed, despite the routine use of stool culture media appropriate for vibrio isolation. bacteremic infections were severe and occurred only in patients with underlyin ... | 1983 | 6625378 |
| seasonal abundance of total and pathogenic vibrio parahaemolyticus in alabama oysters. | recent vibrio parahaemolyticus outbreaks associated with consumption of raw shellfish in the united states focused attention on the occurrence of this organism in shellfish. from march 1999 through september 2000, paired oyster samples were collected biweekly from two shellfish-growing areas in mobile bay, ala. the presence and densities of v. parahaemolyticus were determined by using dna probes targeting the thermolabile hemolysin (tlh) and thermostable direct hemolysin (tdh) genes for confirma ... | 2003 | 12620838 |
| variability of total and pathogenic vibrio parahaemolyticus densities in northern gulf of mexico water and oysters. | vibrio parahaemolyticus is indigenous to coastal environments and a frequent cause of seafood-borne gastroenteritis in the united states, primarily due to raw-oyster consumption. previous seasonal-cycle studies of v. parahaemolyticus have identified water temperature as the strongest environmental predictor. salinity has also been identified, although it is evident that its effect on annual variation is not as pronounced. the effects of other environmental factors, both with respect to the seaso ... | 2007 | 17921270 |
| relationships between environmental factors and pathogenic vibrios in the northern gulf of mexico. | although autochthonous vibrio densities are known to be influenced by water temperature and salinity, little is understood about other environmental factors associated with their abundance and distribution. densities of culturable vibrio vulnificus containing vvh (v. vulnificus hemolysin gene) and v. parahaemolyticus containing tlh (thermolabile hemolysin gene, ubiquitous in v. parahaemolyticus), tdh (thermostable direct hemolysin gene, v. parahaemolyticus pathogenicity factor), and trh (tdh-rel ... | 2010 | 20817802 |
| effects of desiccation practices of cultured atlantic oysters (crassostrea virginica) on vibrio spp. in portersville bay, alabama, usa. | the expansion of off-bottom aquaculture to the gulf of mexico has raised public health concerns for human health officials. high temperatures in the gulf of mexico are associated with high levels of vibrio parahaemolyticus and vibrio vulnificus. routine desiccation practices associated with off-bottom aquaculture expose oysters to ambient air, allowing vibrio spp. to proliferate in the closed oyster. currently, there is limited research on the length of time needed for vibrio spp. levels in desi ... | 2017 | 28696147 |
| effects of ambient exposure, refrigeration, and icing on vibrio vulnificus and vibrio parahaemolyticus abundances in oysters. | vibrio vulnificus (vv) and v. parahaemolyticus (vp) illnesses are typically acquired through the consumption of raw molluscan shellfish, particularly oysters. as vibrio spp. are naturally-occurring bacteria, one means of mitigation of illness is achieved by limiting post-harvest growth. in this study, effects of ambient air storage, refrigeration, and icing of oysters on vibrio spp. abundances were examined at two sites in alabama (al) [dog river (dr) and cedar point (cp)] and one site in delawa ... | 2017 | 28482282 |
