We found that Vibrio cholerae 569B produced much more cholera enterotoxin in the presence of added carbon dioxide than in its absence. An atmosphere of 10% carbon dioxide was optimal for maximal enterotoxin production.

A non-agglutinable Vibrio cholerae strain isolated from the blood of a child with kwashiorkor and fever was shown to have the potential to invade as well as to produce a toxin resembling cholera toxin.

We evaluated the recently developed dipsticks for the rapid detection of Vibrio cholerae serotypes O1 and O139 from rectal swabs of hospitalized diarrheal patients after enrichment for 4 h in alkaline peptone water. The sensitivity and specificity of the dipsticks were above 92 and 91%, respectively. The dipsticks represent the first rapid test which has been successfully used to diagnose chole...

In the control of an epidemic of cholera the importance of complete freedom from cholera vibrio of the stools of cases treated by seven-day drug therapy, and the prophylactic treatment of contacts with the drug, is emphasized. The role of two properties of this drug-namely, the absence of toxic action and slow absorption and slow excretion-is discussed in its bearing on future sulpha therapy as...

Vibrio cholerae O1 Amazonia is a pathogen that was isolated from cholera-like diarrhea cases in at least two countries, Brazil and Ghana. Based on multilocus sequence analysis, this lineage belongs to a distinct profile compared to strains from El Tor and classical biotypes. The genomic analysis revealed that it contains Vibrio pathogenicity island 2 and a set of genes related to pathogenesis a...

There are various human diseases caused by Vibrio species which are pathogenic in nature these diseases are mainly water-borne. In this case “To Study the Therapeutic Role of Indian Spices In The Treatment Of Gastrointestinal Disease Caused By Vibrio Species”. I have chosen fifteen types of Indian spices which are as follows Amomum subulatum, Brassica nigra, Capsicum annuum, Cinnamomum tamala, ...

On July 20, 2010, three cases of cholera were reported from a district hospital in Ca Mau province, Vietnam. We investigated the likely source and mode of transmission of the outbreak. All hospitals in the province were requested to notify cases of acute watery diarrhoea. Epidemiological, clinical, and laboratory data were collected. Between July 12 and 22, seven cases with positive culture for...

Sensitivity testing on Vibrio cholerae isolates during an epidemic in 1998 in Kelantan identified strains resistant to tetracycline. This prompted a change in the usual management of cholera in Kelantan. The antibiotic of choice was changed from tetracycline to erythromycin.

Vibrio cholerae is the causative agent of the disease cholera, characterized by profuse watery diarrhoea. Two of the main virulence factors associated with the disease are cholera toxin (CT) and toxin-coregulated pilus (TCP). Expression of CT and TCP is regulated via a complex cascade of factors that respond to environmental signals, but ultimately ToxT is the direct transcriptional activator o...

A variety of foods have been implicated as vehicles for the causal agent of cholera, Vibrio cholerae. Depending on the type of food, contamination can occur prior to harvesting or during handling and preparation. The viability of the organisms in food is influenced by environmental conditions and handling, and these factors, along with the varying likelihood of contamination, determine the exte...
