Prevalent chromosome fusion in Vibrio cholerae O1. [PDF]

Nat Commun
Abstract Two circular chromosomes are a defining feature of the bacterial family Vibrionaceae, including the pathogen Vibrio cholerae, with rare reports of isolates with a single, fused chromosome. Here, we use long-read sequencing to analyse 467 V. cholerae O1 isolates from 47 cholera patients and household contacts in Bangladesh.

Vibrio cholerae O1 isolated in Kenya [PDF]

Journal of Clinical Microbiology, 1982
Biological and serological analyses of 272 isolates of Vibrio cholerae O1 from six epidemics and from a few sporadic cases in Kenya were carried out. All of the isolates were identified as V. cholerae biotype E1 Tor, and 210 out of 272 isolates were hemolytic as examined by Feeley's method.

Pili of Vibrio cholerae non-O1 [PDF]

Infection and Immunity, 1990
Pili of Vibrio cholerae non-O1 strain S7 were purified and characterized. The pili of S7 were morphologically, electrophoretically, and immunologically (as far as polyclonal antibody was used) indistinguishable from the 16-kilodalton pili of V. cholerae O1 strain 82P7. The purified pili and organisms had D-mannose- and L-fucose-resistant hemagglutinin.

Comparative study of Vibrio cholerae non-O1 protease and soluble hemagglutinin with those of Vibrio cholerae O1 [PDF]

Infection and Immunity, 1987
Protease and soluble hemagglutinating activities produced by a non-O1 Vibrio cholerae strain isolated from a patient with diarrhea were compared with similar activities produced by V. cholerae O1. The soluble protease activities were indistinguishable in heat stability, immunodiffusion, inhibition by antiserum, and electrophoretic analysis.

Vibrio cholerae non-serogroup O1 cystitis [PDF]

Journal of Clinical Microbiology, 1989
We report a case of a patient who developed cystitis caused by non-serogroup O1 Vibrio cholerae after swimming in the Chesapeake Bay. Treatment was empirical, with complete symptomatic resolution. Genitourinary tract infections by Vibrio spp. are uncommon but should be considered when cystitis occurs after saltwater exposure in appropriate geographic ...

Diagnosis of Vibrio cholerae O1 Infection in Africa [PDF]

Journal of Infectious Diseases, 2013
Isolation of Vibrio cholerae O1 is necessary for cholera outbreak confirmation. Rapid diagnostic testing of fecal specimens, based on lipopolysaccharide detection of V. cholerae O1 or O139, may assist in early outbreak detection and surveillance. Cary-Blair transport medium is recommended for specimen transport. Filter paper, although used in epidemics,

Non-O1 Vibrio cholerae unlinked to cholera in Haiti [PDF]

Proceedings of the National Academy of Sciences, 2012
Beginning with the observations of John Snow, many formal epidemiologic and molecular studies have corroborated the idea that cholera toxin-producing Vibrio cholerae (the agent of cholera) can move great distances via human activity. Recently “shoe leather”-based epidemiologic and whole genome-based molecular approaches have provided compelling ...

New Vibrio cholerae O1 Biotype ElTor bacteriophages [PDF]

Virology Journal, 2005
AbstractWe report the presence of three new O1 ElTor vibriophages named AS1, AS2 and AS3, isolated from the sewage and pond waters of the outskirts of Kolkata. A few phages, named AS4, with hexagonal heads and abnormally long tails with typical curly projections were also found in the water samples.

Serotype conversion in Vibrio cholerae O1. [PDF]

Proceedings of the National Academy of Sciences, 1992
Vibrio cholerae O1 exists as two major serotypes, Inaba and Ogawa, which are associated with the O antigen of the lipopolysaccharide and are capable of unequal reciprocal interconversion. The 20-kilobase rfb regions encoding O-antigen biosynthesis in strains 569B (Inaba) and O17 (Ogawa) have been cloned in Escherichia coli K-12 and the nucleotide ...

Role of cholera toxin in enteric colonization by Vibrio cholerae O1 in rabbits [PDF]

Infection and Immunity, 1985
The role of cholera toxin (CT) in mucosal colonization by Vibrio cholerae O1 was studied in rabbits by using toxinogenic V. cholerae and nontoxinogenic (A-B+ or A-B-) recombinant mutants derived from them. After oral inoculation, toxinogenic strains colonized intestinal mucosa significantly more efficiently than did either A-B- or A-B+ mutants; average
