Abstract Four cholera outbreaks were reported in the Central African Republic during 1997–2016. We show that outbreak isolates Vibrio cholerae O1 serotype Inaba from 3 seventh pandemic El Tor sublineages originating West Africa (sublineages T7 and T9) or Great Lakes Region (T10).

Seawater and plankton samples were collected over a period of 17 months from November 1998 to March 2000 along the coast of Peru. Total DNA was extracted from water and from plankton grouped by size into two fractions (64 micro m to 202 micro m and >202 micro m). All samples were assayed for Vibrio cholerae, V. cholerae O1, V. cholerae O139, and ctxA by PCR. Of 50 samples collected and tested, ...

An acute diarrhea outbreak, with 2170 cases, was described during January to July, 2004, in São Bento do Una, Pernambuco. 582 stools were examined and an enteric pathogen was recovered in 25% (145 patients). Aeromonas species were the most frequent (114-19.5%) and the main isolates were Aeromonas caviae (57-9.8%), Aeromonas veronii biovar sobria (23-3.9%), Aeromonas veronii biovar veronii (15-2...

Septicemia of Vibrio spp. such as non-O1 Vibrio cholerae presented with diarrhea, fasciitis, cellulitis or otitis media are common in cirrhotic patients (Lin, C.-J., Chiu, C.-T., Lin, D.-Y., et al., Am. J. Gastroenterol., 91, 336-340, 1996). It may result from a lower C3/C4 level, a lower serum ferritin level or opsonophagocytosis dysfunction. High mortality in such cases has been noted. Howeve...

We report on the development and testing of a novel, rapid, colorimetric immunodiagnostic kit, Cholera SMART, for direct detection of the presence of Vibrio cholerae O1 in clinical specimens. Unlike conventional culture methods requiring several days to complete, the Cholera SMART kit can be used directly in the field by untrained or minimally skilled personnel to detect V. cholerae O1 in less ...

We report the draft genome sequencing of five Vibrio cholerae O1 El Tor clinical isolates collected in the Russian Federation from imported cholera cases in 2006, 2010, and 2012. In the initial phylogenetic analysis, one isolate clustered with the Haiti/Nepal-4 group.

The presence of Vibrio cholerae non-O1 in water supplies for human consumption in the city of Campeche and rural locality of Bécal was investigated. V. cholerae non-O1 was detected in 5.9% of the samples obtained in deep pools of Campeche. Studies conducted in Bécal and neighbourhood of Morelos in Campeche indicated that collected samples harbored V. cholerae non-O1 in 31.5% and 8.7% respective...

The National Institute of Communicable Diseases (NICD), Delhi, India, conducts a laboratory-based surveillance of cholera cases referred from the Infectious Disease Hospital, Delhi. The prevalence and antimicrobial susceptibilities of Vibrio cholerae O1, O139, and others, isolated from cholera patients for nine years, were analyzed to determine the changing trends in their isolation and drug-re...

Vibrio cholerae is ubiquitous in aquatic environments, with environmental toxigenic V. cholerae O1 strains serving as a source for recurrent cholera epidemics and pandemic disease. However, a number of questions remain about long-term survival and evolution of V. cholerae strains within these aquatic environmental reservoirs. Through monitoring of the Haitian aquatic environment following the 2...

A total of 431 rectal swabs, collected from acute diarrheal cases at a surveillance site and at different diarrheal outbreak areas of Orissa from May to October 2005, were bacteriologically analyzed. Out of 265 culture-positive samples, Vibrio cholerae O1 was isolated in 56 samples (20.8%), of which 37 were the Inaba serotype and 19 were the Ogawa. The antibiogram profile revealed that all the ...
