| vibrio vulnificus infections associated with eating raw oysters--los angeles, 1996. | of all foodborne infectious diseases, infection with vibrio vulnificus is one of the most severe; the case-fatality rate for v. vulnificus septicemia exceeds 50%. in immunocompromised hosts v. vulnificus infection can cause fever, nausea, myalgia, and abdominal cramps 24-48 hours after eating contaminated food; because the organism can cross the intestinal mucosa rapidly, sepsis and cutaneous bullae can occur within 36 hours of the initial onset of symptoms. cases are most commonly reported duri ... | 1996 | 8965788 |
| phenotypic characterization of vibrio vulnificus biotype 2, a lipopolysaccharide-based homogeneous o serogroup within vibrio vulnificus. | in this study, we have reevaluated the taxonomic position of biotype 2 of vibrio vulnificus. for this purpose, we have biochemically and serologically characterized 83 biotype 2 strains from diseased eels, comparing them with 17 biotype 1 strains from different sources. selected strains were also molecularly analyzed and tested for eel and mouse pathogenicity. results have shown that biotype 2 (i) is biochemically homogeneous, indole production being the main trait that distinguishes it from bio ... | 1996 | 8975619 |
| siderophore-mediated iron acquisition mechanisms in vibrio vulnificus biotype 2. | vibrio vulnificus biotype 2 is a primary pathogen for eels and, as has recently been suggested, an opportunistic pathogen for humans. in this study we have investigated the ability of v. vulnificus biotype 2 to obtain iron by siderophore-mediated mechanisms and evaluated the importance of free iron in vibriosis. the virulence degree for eels was dependent on iron availability from host fluids, as was revealed by a reduction in the 50% lethal dose for iron-overloaded eels. this biotype produced b ... | 1996 | 8975620 |
| cloning and nucleotide sequencing of the protease gene of vibrio vulnificus. | the gene (vvp) encoding a thermolabile protease of vibrio vulnificus was cloned and sequenced. the transcription start point was also determined by primer extension. the product of this gene is very likely the secretory neutral metalloprotease that has been purified and characterized previously. | 1996 | 8996115 |
