Organisms, including Vibrio cholerae, can be transferred between harbors in the ballast water of ships. Zones in the Caribbean region where distance from shore and water depth meet International Maritime Organization guidelines for ballast water exchange are extremely limited. Use of ballast water treatment systems could mitigate the risk for organism transfer.

Vibrio cholerae O139 is a recently identified non-O1 V. cholerae strain responsible for outbreaks of epidemic cholera in India, Bangladesh, and Thailand in the past 2 years. Other workers have demonstrated the presence of the cholera toxin genetic element in V. cholerae O139, unlike the situation for other non-O1 V. cholerae strains. We sought to compare further this strain with strains of V. c...

Draft whole-genome sequencing of the Vibrio cholerae О1 El Tor clinical strain L3226, isolated in Moscow in 2010, was carried out. Various mutations in the virulence-associated mobile elements were determined in its genome that differentiated this strain from the reference V. cholerae О1 El Tor strain N16961.

This study reported the incidence of potentially pathogenic Vibrio spp. in fresh seafood from Itu creek. Studies were carried out to isolate, identify and characterized different Vibrio species in fish, crayfish and periwinkle obtained from the Itu creeks. Different parts analyzed using standard microbiological techniques were the gills, intestine and the body surfaces. The Vibrio species isola...

The fi(+) and fi(-) R factors are unstable in Vibrio cholerae even on selective media containing antibiotics, although a temperature-sensitive kanamycin resistance factor and its recombinants are stably maintained in V. cholerae at low temperatures.

We used multilocus sequence typing and variable number tandem repeat analysis to determine the clonal origins of Vibrio cholerae O1 El Tor strains from an outbreak of cholera that began in 2009 in Papua New Guinea. The epidemic is ongoing, and transmission risk is elevated within the Pacific region.

BACKGROUND Vibrio cholerae excreted by cholera patients is "hyperinfectious" (HI), which can be modeled by passage through infant mice. Immunization of adult female mice with V. cholerae outer-membrane vesicles (OMVs) passively protects suckling mice from challenge. Although V. cholerae is unable to colonize protected pups, the bacteria survive passage and have the potential to be transmitted t...

Study was conducted to check the distribution and antibiotic susceptibility of Vibrio cholerae from poultry and poultry environment of Bangladesh. Isolated strains were identified following standard cultural, morphological, biochemical and serological agglutination tests. Selected V. cholerae isolates were subjected to 11 antibiotics using disc diffusion method to test sensitivity. V. cholerae ...

Vibrio cholerae, the agent of cholera, is a normal inhabitant of aquatic environments, in which it survives under a wide range of conditions of pH and salinity. In this work, we identified the nhaA gene in a wild-type epidemic strain of V. cholerae O1. nhaA encodes a protein of 382 amino acids that is very similar to the proteins NhaA of Vibrio parahaemolyticus, Vibrio alginolyticus ( approxima...

The presence of Vibrio cholerae in the environment is key to understanding the epidemiology of cholera. The gold standard for laboratory confirmation of V. cholerae from water is a culture method, but this requires laboratory infrastructure. A rapid diagnostic test that is simple, inexpensive, and can be deployed widely would be useful for confirming V. cholerae in samples of environmental wate...
