Here, we report the completed genome sequences for two non-O1/non-O139 Vibrio cholerae isolates. Each isolate has only a single chromosome, as opposed to the normal paradigm of two chromosomes found in all other V. cholerae isolates.

cholera outbreak is more common in developing countries. the causative agent of the disease is vibrio cholerae strains o1 and o139. traditional diagnostic testing for vibrio is not always reliable, because vibrio can enter a viable but non cultivable state. therefore, nucleic acid-based tests have emerged as a useful alternative to traditional enrichment testing.       in this investigation, a ...

background: the virulence of a pathogenic vibrio cholerae is dependent on a discrete set of genetic determinants. in this study, we determined the distribution of virulence determinants among the clinical and environmental isolates of v. cholerae. methods: the antibiotic resistance profiles of the isolates were determined using standard disk diffusion assay. pcr assay was performed to analyze t...

This is a retrospective study on Vibrio spp. isolated from patients with diarrhea (both inpatients and outpatients) at Siriraj Hospital, Bangkok, Thailand from January 1994 to December 2001. Of the 33,334 fecal specimens sent for culture, 2,229 (6.68%) were positive for pathogenic bacteria. The most commonly isolated bacteria was Vibrio (1,183 of 2,229 isolates, 53%). Of these 1,183 isolates, t...

Cholera is now considered to be endemic in Haiti, often with increased incidence during rainy seasons. The challenge of cholera surveillance is exacerbated by the cost of sample collection and laboratory analysis. A diagnostic tool is needed that is low cost, easy-to-use, and able to detect and quantify Vibrio cholerae accurately in water samples within 18-24h, and perform reliably in remote se...

Bacteremia due to Vibrio cholerae non-O1 and non-O139 is a rare condition and potentially fatal. We report a case of bacteremia due to V. cholerae non-O1 and non-O139 in a Portuguese male with Hepatitis C cirrhosis, admitted due to acute diarrhea, after consuming shrimp. He had no recent travels. To our knowledge, this is the first reported case of bacteremia due to V. cholerae non-O1 and non-O...

A total of 31 strains of Vibrio cholerae O1 (10 from outbreak cases and 7 from surface water) and non-O1 (4 from clinical and 10 from surface water sources) isolated between 1993 and 1997 were examined with respect to presence of cholera enterotoxin (CT) gene by PCR-based assays, resistance to antibiotics, plasmid profiles and random amplified polymorphic DNA (RAPD) analysis. All were resistant...

An epidemic of a cholera-like disease occurred among Khmers in a camp in Aranyaprathet, Thailand, in May 1990. Of 215 patients with diarrhea, Vibrio cholerae O1 was isolated from 25 (12%) and V. cholerae non-O1 was isolated from 15 (7%). Five of 15 (33%) non-O1 V. cholerae isolates hybridized with two different oligonucleotide probes previously used to detect V. cholerae non-O1 that produces a ...
