Marine bacteria are known to produce many bioactive molecules and extracellular enzymes of commercial importance. We have investigated the bacterial diversity of the coastal area of Karwar, Karnataka State, India. Among these bacterial isolates, five bacterial strains were selected and identified by their morphological, biochemical characteristics and phylogenetic analysis based on 16S rRNA gen...
Vibrio vulnificus infection is the leading cause of death related to seafood consumption in the United States. This virulent, gram-negative bacterium causes two distinct syndromes. The first is an overwhelming primary septicemia caused by consuming raw or undercooked seafood, particularly raw oysters. The second is a necrotizing wound infection acquired when an open wound is exposed to warm sea...
Necrotizing fasciitis is a severe life-threatening infection of the deep subcutaneous tissues and fascia. Infection with Vibrio vulnificus, a halophilic Gram-negative bacillus found worldwide in warm coastal waters, can lead to severe complications, particularly among patients with chronic liver diseases. We herein present an unusual case of necrotizing fasciitis caused by V. vulnificus trigger...
This study was carried out to investigate the occurrence of potentially pathogenic species of vibrio in sea water and estuarine environments of the Caspian Sea in the Golestan province of Iran. A total of 127 water samples from coastal waters as well as from river and estuaries were collected and analyzed by culture, during April and September 2001. Following prompt centrifugation, the resusp...
Vibrio vulnificus causes septicemia and wound infections in immunocompromised humans. The capsular polysaccharide of Vibrio vulnificus (VvPS) is critical for virulence. We synthesized conjugate vaccines of carbotype 1 VvPS under conditions and in formulations suitable for human use. Purified VvPS was conjugated to tetanus toxoid (TT) or to inactivated V. vulnificus cytolysin or elastase by two ...
Introduction Vibrio vulnificus is an opportunistic human pathogen that naturally inhabits estuarine and coastal waters worldwide. This gram-negative bacterium is ubiquitous in these environments and has been isolated from water, sediments, fish, and shellfish such as bivalve mollusks. V. vulnificus is a medically important pathogen due to its ability to cause fulminant and potentially fatal sys...
The recent emergence of the human-pathogenic Vibrio vulnificus in Israel was investigated by using multilocus genotype data and modern molecular evolutionary analysis tools. We show that this pathogen is a hybrid organism that evolved by the hybridization of the genomes from 2 distinct and independent populations. These findings provide clear evidence of how hybridization between 2 existing and...
The abundance of Vibrio vulnificus in coastal environments has been linked to water temperature, while its relationship to salinity is less clear. We have developed a culture-independent, most-probable-number quantitative PCR approach to examine V. vulnificus population dynamics in Barnegat Bay, N.J. Based on the combined analysis of our results from Barnegat Bay and from the literature, the pr...
The inter- and intrageneric relationships of the genus Vibrio were investigated by performing a comparative analysis of the 16S rRNAs of 10 species, including four pathogenic representatives. The results of immunological and 5S rRNA studies were confirmed in that the genus is a neighboring taxon of the family Enterobacteriaceae. With regard to the intrageneric structure, Vibrio alginolyticus, V...
