This study deals with the influence of water physico-chemical properties, tides, rainfall and fecal pollution on the abundance of enteropathogens in a main distributary of the Ganges, in the endemic cholera belt of West Bengal. Between January and June 2011, water and sediments were sampled from two sites of the Hooghly River by Kolkata and Diamond Harbour.(More)
Diarrheal diseases are a major cause of morbidity and mortality in developing countries. Among the bacterial pathogens, diarrheagenic Escherichia coli are most frequently connected in cases with epidemic and endemic diarrhea worldwide. Environmental surveillance for monitoring of E.coli is very rare. In the present study, we have applied a modified(More)
Conventional procedures for qualitative assessment of coliphage are time consuming multiple step approach for achieving results. A modified and rapid technique has been introduced for determination of coliphage contamination among potable water sources during water borne outbreaks. During December 2013, 40 water samples from different potable water sources,(More)
The Gangetic delta is a century-old cholera endemic belt where the role of riverine-estuarine ecosystem in cholera transmission has never been elucidated. Seasonality, distribution, and abundance of environmental Vibrio cholerae O1/O139 and vibriophage in Hooghly riverine-estuarine environment and their correlation with cholera incidence pattern in West(More)
Diarrhoea still remains an unsolved enigma in developing countries, a major concern for the health planners. We targeted the abundance and toxicity of Vibrio cholerae non-O1/non-O139 (NOVC) in Gangetic riverine-estuarine ecosystem. A total of 74 V. cholerae were isolated from 120 water samples (68 NOVC, 6 V. cholerae O1) from two sampling sites off river(More)
Diarrheal disease remains an unsolved problem in developing countries. The emergence of new etiological agents (non-cholera vibrios) is a major cause of concern for health planners. We attempted to unveil the seasonal dynamics of entero-pathogenic Vibrios in Gangetic riverine-estuarine ecosystem. 120 surface water samples were collected for a period of one(More)
