OBJECTIVE This study reports re-emergence of Vibrio cholerae O139 in Pakistan in 2000-2001 from a tertiary care hospital in Karachi, Pakistan. METHODS This descriptive study was conducted from 2000-2001. Stool samples were taken from inpatients or those referred to the laboratory from other hospitals, clinics and general practitioners. Samples were processed and Vibrio cholerae isolates were ...
Members of the Vibrio genus are autochthonous inhabitants of aquatic environments and play vital roles in sustaining the aquatic milieu. The genus comprises about 100 species, which are mostly of marine or freshwater origin, and their classification is frequently updated due to the continuous discovery of novel species. The main route of transmission of Vibrio pathogens to man is through drinki...
An Elek test for enterotoxin-producing strains of Vibrio cholerae is described. Thirty-five out of 37 strains of classical V. cholerae produced positive reactions, but only 1 of 69 E1 Tor vibrio strains was reactive. Tox(-) mutants of V. cholerae were also unreactive in the Elek test.
Vibrio cholerae, a Gram-negative pathogen autochthonous to the aquatic environment, is the causative agent of cholera. Here, we report the complete genome sequence of V. cholerae G4222, a clinical isolate from South Africa.
Vibrio alginolyticus has two types of flagella (polar and lateral) in one cell. We isolated mutants with only a polar flagellum (Pof+ Laf-) or only lateral flagella (Pof- Laf+). Using these mutants, we demonstrated that the energy sources of the lateral and polar flagellar motors in V. alginolyticus are H+ and Na+ motive forces, respectively, as in the related species V. parahaemolyticus.
Vibrio fluvialis is a halophilic bacterium found in many environments and is mainly associated with sporadic cases and outbreaks of gastroenteritis in humans. Here, we describe the genome sequences of environmental strains of V. fluvialis 560 (Vf560) and V. fluvialis 539 (Vf539) possessing a variant of the integrative and conjugative element (ICE) SXT for the first time in Brazil and South Amer...
A halophilic Vibrio species was isolated from blood cultures from a 59-year-old male with enteritis. The strain differed from Vibrio parahaemolyticus and Vibrio alginolyticus by its ability to ferment lactose, its production of beta-galactosidase, and its lower NaCl tolerance. A report of this infection and a description of the isolate is presented.
Draft Genome Sequences of Vibrio sp. Strains Isolated from Tetrodotoxin-Bearing Scavenging Gastropod
Vibrio sp. strains JCM 18905 and JCM 19053 were isolated from a tetrodotoxin (TTX)-bearing scavenging gastropod, and Vibrio sp. strain JCM 18904 was isolated from a sea cucumber. All these are closely related to Vibrio alginolyticus. Their comparative genome information is useful for studies of TTX production in bacteria.
A strain of Vibrio (KC13.17.5) causing acute hepatopancreatic necrosis disease (AHPND) in shrimp in northern Vietnam was isolated. Normally, AHPND is caused by Vibrio parahaemolyticus, but the genomic sequence of the strain indicated that it belonged to Vibrio harveyi. The sequence data included plasmid-like sequences and putative virulence genes.
We present the draft whole-genome sequence of a Vibrio cholerae strain (Vc25-3) isolated from Drakes Bay, California. This environmental isolate has an atypical morphology and is ortho-nitrophenyl-β-d-galactoside (ONPG)-negative.
