The bacterial flora of blue crabs (Callinectes sapid us) from Chesapeake Bay was examined. Hemolymph of normal, healthy blue crabs was found non-sterile, with total bacterial counts ranging from <100 to >3.0 x 10 5 on a seawater-based medium and 0 to >10 5 on Standard Methods Agar. Counts of 0-10 3 were observed on TCBS agar. Vibrio spp., including Vibrio parahaemolyticus, were the major taxono...

Vibrio spp. are gram-negative, facultative anaerobic, non-spore-forming bacilli which are oxidase positive and halophilic bacteria widely spread in seaand brackwater worldwide. The genus Vibrio includes several foodborne pathogens which cause a spectrum of clinical conditions including septicaemia, cholera and milder forms of gastroenteritis. The species most commonly associated with foodborne ...

BACKGROUND Many bacteria, including Vibrio spp., regulate virulence gene expression in a cell-density dependent way through a communication process termed quorum sensing (QS). Hence, interfering with QS could be a valuable novel antipathogenic strategy. Cinnamaldehyde has previously been shown to inhibit QS-regulated virulence by decreasing the DNA-binding ability of the QS response regulator L...

The occurrence, diversity, and pathogenicity of Vibrio spp. were investigated in two estuaries along the Italian Adriatic coast. Vibrio alginolyticus was the predominant species, followed by Vibrio parahaemolyticus, non-O1 Vibrio cholerae, and Vibrio vulnificus. By using a biochemical fingerprinting method, all isolates were grouped into nine phenotypes with similarity levels of 75 to 97.5%. Th...

We report the draft genome sequence of Vibrio anguillarum ATCC 14181, a Gram-negative, hemolytic, O2 serotype marine bacterium that causes mortality in mariculture species. The availability of this genome sequence will add to our knowledge of diversity and virulence mechanisms of Vibrio anguillarum as well as other pathogenic Vibrio spp.

INTRODUCTION Necrotizing fasciitis (NF) is a life threatening infectious disease with a high mortality rate. We carried out a microbiological characterization of the causative pathogens. We investigated the correlation of mortality in NF with bloodstream infection and with the presence of co-morbidities. METHODS In this retrospective study, we analyzed 323 patients who presented with necrotiz...

Vibrio vulnificus was found to produce a chemical that induced the expression of Vibrio fischeri lux genes. Electron spray ionization-mass spectrometry and 1H nuclear magnetic resonance analyses indicated that the compound was cyclo(L-Phe-L-Pro) (cFP). The compound was produced at a maximal level when cell cultures reached the onset of stationary phase. Sodium dodecyl sulfate-polyacrylamide gel...

Quantification of Vibrio spp. and abiotic environmental factors on the proliferation and longevity of V. parahaemolyticus and V. cholerae was studied. Water samples were collected onboard CRV Sagar Purvi from Veli, Neendakara, Kochi, Calicut and Kasaragod along the Kerala coast for hydrological and microbiological parameters. Pearson correlation and regression analysis were done for evaluating ...

Live eels and processed fish products from Malaysia are routinely checked for microbial pathogens before export to Japan. The eels and water from the ponds are screened for Vibrio cholerae and Salmonella spp, whereas the processed fish products are tested for microbial contamination (aerobic plate count), coliforms, E. coil and Vibrio cholerae. Results showed that live eels and water samples we...

A survey was carried out on the prevalence of bacteria and ciliate protozoan of Pellaells indiclls obtained from Ennore estuary, Chennai (Madras), India from November 1989 to July 1992. The study r~vealed the occurrence of Vibrio parahaemolyticus, V. VUlllijiCUS, V. harvey;, V. allguillarum, V. damsela, Pseudomollas sp., P. aemgillo.\'{/ and a tilamentous bacterium Leucothrix sp. This study als...
