Modified CAMP test for biogrouping Vibrio cholerae O1 strains and distinguishing them from strains of V. cholerae non-O1 [PDF]

Journal of Clinical Microbiology, 1994
A modified CAMP test was used to identify 973 Vibrio cholerae isolates by phenotype. Eltor and non-O1 strains were CAMP positive; classical strains were CAMP negative. Sausage-shaped zones of hemolysis of eltor strains were easily distinguished from narrower bands of non-O1 isolates.

Non-O1/Non-O139 Vibrio cholerae Carrying Multiple Virulence Factors and V. cholerae O1 in the Chesapeake Bay, Maryland [PDF]

Applied and Environmental Microbiology, 2015
ABSTRACT Non-O1/non-O139 Vibrio cholerae inhabits estuarine and coastal waters globally, but its clinical significance has not been sufficiently investigated, despite the fact that it has been associated with septicemia and gastroenteritis. The emergence of virulent non-O1/non-O139 V. cholerae

Simple differentiation of Vibrio cholerae O139 from V. cholerae O1 and non-O1, non-O139 by modified CAMP test [PDF]

Journal of Clinical Microbiology, 1996
Strong positive CAMP reactions were demonstrated by 121 Vibrio cholerae O139 and 504 El Tor isolates, and weak positive CAMP reactions were shown by 235 non-O1, non O139 isolates when these isolates were tested by a modified CAMP technique. Thirty-five classical biotype V. cholerae O1 isolates included in the tests were all CAMP negative.

Comparative genomic characterization of a Thailand-Myanmar isolate, MS6, of Vibrio cholerae O1 El Tor, which is phylogenetically related to a "US Gulf Coast" clone. [PDF]

PLoS ONE, 2014
BACKGROUND: The cholera outbreaks in Thailand during 2007-2010 were exclusively caused by the Vibrio cholerae O1 El Tor variant carrying the cholera toxin gene of the classical biotype. We previously isolated a V. cholerae O1 El Tor strain from a patient

Draft Genome Sequence of Environmental Vibrio cholerae 2012EL-1759 with Similarities to the V. cholerae O1 Classical Biotype [PDF]

Genome Announcements, 2014
ABSTRACT Vibrio cholerae 2012EL-1759 is an environmental isolate from Haiti that was recovered in 2012 during a cholera outbreak. The genomic backbone is similar to that of the prototypical V.

Environmental Surveillance of Vibrio cholerae O1/O139 in the Five African Great Lakes and Other Major Surface Water Sources in Uganda

Frontiers in Microbiology, 2018
Cholera is a major public health problem in the African Great Lakes basin. Two hypotheses might explain this observation, namely the lakes are reservoirs of toxigenic Vibrio cholerae O1 and O139 bacteria, or cholera outbreaks are a result of repeated ...

Hybrid Vibrio cholerae El Tor Lacking SXT Identified as the Cause of a Cholera Outbreak in the Philippines

mBio, 2015
Cholera continues to be a global threat, with high rates of morbidity and mortality. In 2011, a cholera outbreak occurred in Palawan, Philippines, affecting more than 500 people, and 20 individuals died.

Detection of Phage-Induced Mobile Genetic Elements in Strains of Vibrio cholerae O1 Biovar El Tor

Проблемы особо опасных инфекций, 2023
The acquisition of new mobile genetic elements contributes to the genetic diversity of Vibrio cholerae strains. An important role in this process belongs to the genetic material obtained from phages. The aim of this work was to identify phage-induced PLE

ISOLATION OF A NEW VARIANT OF VIBRIO CHOLERAE O1: V. CHOLERAE O1 RIBOTYPE B27 TOXINOGENOTYPE TB31 DURING THE LAST CHOLERA EPIDEMIC IN SENEGAL

Japanese Journal of Medical Science and Biology, 1997
A total of 205 Vibrio cholerae O1 isolates from recent cholera epidemic in Senegal were analyzed by conventional methods, polymerase chain reaction (PCR) for genes encoding cholera toxin (ctx A), zonula occludens toxin (zot) and accessory cholera enterotoxin (ace), ribotyping and toxinogenotyping.

Monitoring Water Sources for Environmental Reservoirs of Toxigenic Vibrio cholerae O1, Haiti

Emerging Infectious Diseases, 2014
An epidemic of cholera infections was documented in Haiti for the first time in more than 100 years during October 2010. Cases have continued to occur, raising the question of whether the microorganism has established environmental reservoirs in Haiti ...
