33 stools from 518 patients suspected of having cholera were examined. from 174 of these patients vibrio ei tor was isolated. po of these strains belonged to phage type iv, 53 to phage type v and one strain was untypable. it is suggested that these strains originated from two different sources.

Louisiana was struck by Hurricane Katrina on August 29, 2005, and by Hurricane Rita on September 24, 2005. The two hurricanes caused unprecedented damage from wind and storm surge to the Louisiana Gulf Coast region, and levee breaks resulted in flooding of large residential areas in and around New Orleans. With the flooding, an immediate public health concern was the potential for outbreaks of ...

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 triple...

We determined the types of cholera toxin (CT) produced by a collection of 185 Vibrio cholerae O1 strains isolated in Bangladesh over the past 45 years. All of the El Tor strains of V. cholerae O1 isolated since 2001 produced CT of the classical biotype, while those isolated before 2001 produced CT of the El Tor biotype.

RATIONALE Mozambique has recorded cyclically epidemic outbreaks of cholera. Antibiotic therapy is recommended in specific situations for management and control of cholera outbreaks. However, an increase in resistance rates to antibiotics by Vibrio cholerae has been reported in several epidemic outbreaks worldwide. On the other hand, there are few recent records of continuous surveillance of ant...

Background: Cholera, an acute diarrhoeal disease caused by Vibrio cholerae still ranks high in the etiology of diarrhoeal diseases in several parts of India. Aim:To study the characteristics and anti-microbial resistance pattern of the Vibrio choleraestrains isolated in our hospital. Methods: Over a 2 year period, stool samples from clinically suspected cholera cases were screened and the isola...

In endemic centres of cholera such as Calcutta and in areas where cholera occurs in epidemic form, vibrios can be isolated not only from cholera cases but also from contacts, healthy individuals, waters, flies and other sources. These vibrios may be divided into two great classes, vibrios that are agglutinable by ** specific cholera serum and those that are not agglutinable by this serum. The c...

We developed a multiplex enzyme-based electrochemical genosensor for sequence-specific detection of multiplex linear-after-the-exponential-PCR amplicons that targeted toxigenic Vibrio cholerae O1 and O139 using novel screen-printed gold electrode bisensors.

Vibrio mimicus, a newly described species of the genus Vibrio has been isolated from stools of 14 patients with diarrhoea. Live cells of all the 14 strains tested caused accumulation of fluid in rabbit gut loops and diarrhoea in infant rabbits. Culture filtrates of all the strains caused increased capillary permeability in rabbit skin; however, five of the filtrates resembled cholera toxin in t...

The outbreak of waterborne disease cholera has been associated with rainfall and flooding events by contamination of potable water with environmental Vibrio cholerae. The continuation of the epidemic in a region, however, is often due to secondary transmission of the initial outbreak strain through human waste. This paper reports, on the contrary, a rapid shift of genotype from one V. cholerae ...
