An epidemiological study was carried out to find out the aetiological agent for diarrhoeal disorders in the cyclone and flood affected areas of Orissa, India. Rectal swabs collected from 107 hospitalized diarrhoea patients were bacteriologically analysed to isolate and identify the various enteropathogens. Detection of toxic genes among E. coli and V.(More)
BACKGROUND We investigated the epidemic of cholera that occurred in Kashipur and Dasmantpur blocks of Orissa, reported during July-September 2007. METHODS Sixty-two rectal swabs and 28 water samples collected from diarrhea patients at different hospitals and villages were bacteriologically analyzed for the identification, antibiogram, and detection of(More)
BACKGROUND & OBJECTIVE Lymphatic filariasis (LF) is a major public health problem in India, accounting for 40 per cent of the global burden. The World Health Organization has launched a global programme to eliminate LF by 2020 and India is a signatory to it. Orissa, an eastern Indian State has long been known to be endemic for LF. Prior to implementation of(More)
Bacteriological analysis of 1,551 stool/rectal swabs from all age groups of diarrhea patients of different hospitals of Orissa from January 2004 to December 2006 was carried out using standard procedures. Among all enteropathogens isolated in 886 culture-positive samples, Escherichia coli constituted 75.5%, including 13.2% pathogenic E. coli; Vibrio(More)
A large outbreak of cholera reported during April-July 2009 in the Kendrapada district of Odisha, India was investigated. Forty-one rectal swabs and 41 water samples, collected from diarrhoeal patients and from different villages were bacteriologically analysed for the isolation of bacterial enteriopathogens, antibiogram profile and detection of various(More)
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(More)
A quadruplex PCR was developed for the simultaneous detection of genes specific for Vibrio cholerae O1 and/or O139 serogroup (wbe and/or wbf), cholera toxin A subunit (ctxA), toxin-coregulated pilus (tcpA), and central regulating protein ToxR (toxR) in a single tube reaction. This is a simple, rapid, and accurate approach for the detection of toxigenic V.(More)
INTRODUCTION The substantial morbidity and mortality associated with recent cholera outbreaks in Haiti and Zimbabwe, as well as with cholera endemicity in countries throughout Asia and Africa, make a compelling case for supplementary cholera control measures in addition to existing interventions. Clinical trials conducted in Kolkata, India, have led to(More)
BACKGROUND A clinical trial conducted in India suggests that the oral cholera vaccine, Shanchol, provides 65% protection over five years against clinically-significant cholera. Although the vaccine is efficacious when tested in an experimental setting, policymakers are more likely to use this vaccine after receiving evidence demonstrating protection when(More)
The emergence and spread of Vibrio cholerae O1 El Tor variant strains causing severe diarrhea has been witnessed worldwide in recent years. In the state of Odisha, India, the spread of the V. cholerae O1 El Tor variant strains was studied during outbreaks in 2008 and 2009. Analysis of 194 V. cholerae O1 Ogawa strains revealed that V. cholerae O1 El Tor(More)
