Consecutive outbreaks of Vibrio cholerae O139 and V. cholerae O1 cholera in a fishing village near Karachi, Pakistan

Transactions of the Royal Society of Tropical Medicine and Hygiene, 2006
In July 2002 and June 2003, cholera outbreaks were detected by a diarrhoea surveillance system in a village outside Karachi, Pakistan. Specimens were culture confirmed. The first outbreak was caused by Vibrio cholerae O139 (n = 30) and the second outbreak by V. cholerae O1 (n = 39).

Environmental and Epidemiological Aspects of V. cholerae O1 Contamination of Water Bodies in the Republic of Kalmykia

ЗДОРОВЬЕ НАСЕЛЕНИЯ И СРЕДА ОБИТАНИЯ - ЗНиСО / PUBLIC HEALTH AND LIFE ENVIRONMENT, 2021
Background: Within the framework of cholera surveillance in the Russian Federation, annual isolation of nontoxigenic V. cholerae O1 strains from water bodies is registered in the Republic of Kalmykia. This fact is the rationale for the present study and analysis of data on contamination of water bodies with V.

Clinical features, antimicrobial susceptibility and toxin production in Vibrio cholerae O139 infection: comparison with V. cholerae O1 infection

Transactions of the Royal Society of Tropical Medicine and Hygiene, 1996
We prospectively compared the clinical features of cholera due to Vibrio cholerae O1 and V. cholerae O139 in 242 men 18-60 years of age, with a history of diarrhoea of 24 h or less, and moderate or severe dehydration. The antimicrobial susceptibility of all of the V.

Non-O1 Vibrio cholerae pathogen from Cyprinus carpio and control with anti-non-O1 V. cholerae egg yolk powder (IgY)

Aquaculture, 2017
Abstract Mass mortality in cultured common carp from a farm of Ganyu county, Jiangsu province, P. R. China was reported. The two dominated isolates named L1 and L2 from diseased common carps were confirmed as non-O1 Vibrio cholerae by biochemical characteristics and molecular tools.

Epidemiology and transmission of V. cholerae O1 and V. cholerae O139 infections in Delhi in 1993.

Journal of diarrhoeal diseases research, 1997
In 1993, rectal swabs from clinically suspected cases of cholera admitted to the Infectious Diseases Hospital (IDH), Delhi were examined for Vibrio cholerae O1 and O139. Epidemiological data of 396 cholera cases were collected before the patients' discharge from IDH. Of the 1528 laboratory-confirmed cholera cases, 46% and 54% were caused by serotype O1

The occurrence of alpha (1----2) linked N-acetylperosamine--homopolymer in lipopolysaccharides of non-O1 Vibrio cholerae possessing an antigenic factor in common with O1 V. cholerae.

Microbiology and immunology, 1991
Chemical analysis was carried out on lipopolysaccharides from Vibrio cholerae bio-serogroup Hakata 487-85. The O-specific chain of the phenol-soluble lipopolysaccharides was demonstrated by 13C-NMR spectroscopy and methylation analysis to contain a linear homopolymer of alpha(1----2) linked N-acetylperosamine (4-acetamido-4,6-dideoxy-D-mannopyranose ...

Vibrio cholerae cytolysin is essential for high enterotoxicity and apoptosis induction produced by a cholera toxin gene-negative V. cholerae non-O1, non-O139 strain

Microbial Pathogenesis, 2008
Cholera toxin (CT) gene-negative Vibrio cholerae non-O1, non-O139 strains may cause severe diarrhea though their pathogenic mechanism remains unclear. V. cholerae cytolysin (VCC) is a pore-forming exotoxin encoded in the hlyA gene of V. cholerae whose contribution to the pathogenesis is not fully understood.

Serotype-shifting gene rfbT is a direct transcriptional target of cAMP receptor protein (CRP) in V. cholerae O1

Biochemical and Biophysical Research Communications, 2019
Ogawa and Inaba are two main serotypes of O1 V. cholerae and alternate among cholera epidemics. The rfbT gene encodes a methyltransferase and is required for Ogawa serotype. The Inaba serotype is the consequence of genetic alterations in rfbT gene which results in loss-of-function enzyme product.
