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 year from 3 sampling sites on the Hooghly river. Five enteropathogenic Vibrio species, V. cholerae (35%), V. parahaemolyticus (22.5%), V… Expand
Environmental Vibrio cholerae non O1/ non O139 from the Gangetic delta: a diarrhoeal disease purview
TLDR
Haemolytic activity and biofilm formation in NOVC, during unfavourable conditions, facilitates gene transfer and emphasises the role of environmental NOVC in diarrhoeal incidence in South Bengal, India. Expand
Environmental Drivers of the Seasonal Prevalence of Enteropathogenic Bacteria in the Gulf Ecosystem of Gujarat, India: Unravelling Its Diarrheal Enigma
Recurrent episodes of water borne diarrheal outbreaks is the pressing public health crisis in the Gulf of Khambat (GoK), Gujarat and its adjoining area. We aimed to identify seasonality ofExpand
Molecular Detection and Distribution of Six Medically Important Vibrio spp. in Selected Freshwater and Brackish Water Resources in Eastern Cape Province, South Africa
TLDR
Correlation analysis revealed that temperature drives the frequency of isolation, whereas salinity drives the composition of the targeted Vibrio species at the sampling sites. Expand
Preponderance of Multidrug-resistant, Toxigenic, and Thermotolerant Enteropathogenic Bacteria in Raw and Cooked Seafood of Indo-Gangetic Basin and Associated Health Risks
TLDR
It is reported for the first time that seafood borne Vibrios are more threatening with respect to their drug resistance ability rather than potable-water VibRIos of this focus, a phenomenon attributed to resistant gene transfer facilitated in chitinous environments. Expand
Waterborne outbreaks in diarrhoea endemic foci of India: a longitudinal exploration and its implications
TLDR
Re-modelling of ‘point-of-use water disinfection’ measures and adequate personal hygiene for healthier community life are strongly recommended. Expand
Seasonal influence, enteropathogenic microbial load and diarrhoeal enigma in the Gangetic Delta, India: Present scenario and health implications.
TLDR
The interplay of seasonal variants on the dynamicity of enteropathogenic bacteria in flowing aquatic ecosystem is established and the existing microbial threats in the Ganga River is categorised to help monitor the conventional as well as emerging diarrhoeal pathogens to reduce diarrheal recurrences. Expand
Enteric viruses, somatic coliphages and Vibrio species in marine bathing and non-bathing waters in Italy.
TLDR
This is the first study showing the occurrence and high concentration of Aichivirus in bathing waters and provides original information, useful in view of a future revision of the European Directive. Expand
Environmental drivers on seasonal abundance of riverine-estuarine V. cholerae in the Indian Sundarban mangrove
TLDR
Gangetic delta is considered as the homeland of cholera, which is thought to be influenced by changes in populations of estuarine Vibrio cholerae, and the role of Sundarban mangrove is established, where V. cholerAE exist in an avirulent condition. Expand
Occurrence of multidrug-resistant bacteria in aquaculture farms in Cte dIvoire (West Africa)
TLDR
The investigation of the presence of bacteria in aquaculture shows microbiological risks for aquatic animals and humans who are in interaction with fish farms and multi-resistance for 3 classes of antibiotics was observed. Expand
Polluted Coastal and Estuarine Environments: A Potential Reservoir for AMR Determinants in Various Pathogenic Bacteria
TLDR
The extent of drug resistance and virulence enhancing mechanisms among three major groups of pathogens such as diarrheagenic E. coli, pathogenic vibrios, and motile aeromonads from estuaries and coastal waters which provide an ideal habitat for the coexistence of pathogens, opportunists, and commensals are dealt with.

Seasonal dynamics of Vibrio cholerae and its phages in riverine ecosystem of Gangetic West Bengal: cholera paradigm
TLDR
A “biomonitoring tool” of physicochemical stimulants, tidal, and climatic variants has been proposed collating V. cholerae and phage dynamics that can forewarn any impending cholera outbreak. Expand
Influence of hydrologic and anthropogenic factors on the abundance variability of enteropathogens in the Ganges estuary, a cholera endemic region.
TLDR
Turbidity-dependent variation of CVC was noteworthy, particularly at Diamond Harbour, where CVC in intertidal surface sediments showed an analogous trend as in surface waters, suggesting bentho-pelagic coupling of Vibrio dynamics. Expand

TLDR
The coexistence of the two vibrios in the slums of Kolkata had a similar seasonality but had distinguishing clinical features suggesting different modes of transmission of these two pathogens. Expand

Diarrheogenic Escherechia coli in potable water sources of West Bengal, India.
TLDR
The presence of multidrug resistant diarrheogenic E.coli justifies the potentiality of potable water sources as its vehicle and as a potent diarrheal inducer in diarrhea prone area along with increasing concern of drug resistance. Expand

PHYSIOCHEMICAL CONDITIONS AND CONTAMINATION WITH VIBRIOS OF SURFACE WATER AT MATLAB, BANGLADESH
TLDR
The present study indicated that the JMBFS / Paul et al. 2012 surface water sources are the main causes of cholera and reestablished the Matlab as epidemic area of Bangladesh. Expand
Is Vibrio fluvialis Emerging As a Pathogen with Epidemic Potential in Coastal Region of Eastern India Following Cyclone Aila?
TLDR
The laboratory results indicate that V. fluvialis behaves more aggressively than V. cholerae O1 in an epidemic situation with a higher attack rate and a different clinical picture, and an in-depth study is required to explore its pathogenicity in detail, geographical distribution, and possible control measures, including development of specific vaccine preparation and determination of its efficacy.

Occurrence, Diversity, and Pathogenicity of HalophilicVibrio spp. and Non-O1 Vibrio cholerae from Estuarine Waters along the Italian Adriatic Coast
TLDR
The production of toxins capable of causing cytoskeleton-dependent changes was detected in a large number of Vibrio strains detected in two estuaries along the Italian Adriatic coast, indicating a significant presence of potentially pathogenic Vibriospp strains along the AdRIatic coast. Expand
Biodiversity of Vibrios
TLDR
Vibrios harbour a wealth of diverse genomes as revealed by different genomic techniques including amplified fragment length polymorphism, multilocus sequence typing, repetetive extragenic palindrome PCR, ribotyping, and whole-genome sequencing, which are probably important driving forces in the evolution and speciation of vibrios.
