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 environmentalVibrio choleraeO1/O139 and vibriophage in Hooghly riverine–estuarine environment and their correlation with cholera incidence pattern in West Bengal, India, have been analyzed for the first time across summer, monsoon, and winter months. A total of 146 water samples collected from two sites of the Hooghly River (Howrah and Diamond Harbour) were analyzed physicochemically along with cultivableVibriocount (CVC),V. choleraeO1/O139, and vibriophages.V. choleraeO1 was detected in 56 (38.3 %) samples, while 66 (45.2 %) were positive forV. choleraeO1 phages. Flood tide, water temperature (31 ± 1.6 °C), and turbidity (≥250 nephelometric turbidity unit (NTU)) significantly stimulatedV. choleraeand vibriophage abundance in riverine ecosystem. Solitary existence ofV. choleraeO1 and phages (p< 0.0001) in aquatic environment divulges the dominance of either of the entity (V. choleraeO1 orV. choleraeO1 Φ) on the other. Significant association (p< 0.05) between Kolkata cholera cases andV. choleraeO1 in aquatic environment implies the role of riverine–estuarine ecosystem in cholera transmission. A “biomonitoring tool” of physicochemical stimulants, tidal, and climatic variants has been proposed collatingV. choleraeand phage dynamics that can forewarn any impending cholera outbreak.
