Seasonal Occurrence of Vibrios in Water and Shellfish Obtained from the Great Kwa River Estuary, Calabar, Nigeria

The prevalence of Vibrio species in shellfish and their seasonal variability in the Great Kwa River estuary (GKWE) were examined. Results revealed a trimodal peak in Vibrio counts, coinciding with meteorological changes and the hot periods of the year. The estuary was constantly faecally polluted, c...

Description
Summary:The prevalence of Vibrio species in shellfish and their seasonal variability in the Great Kwa River estuary (GKWE) were examined. Results revealed a trimodal peak in Vibrio counts, coinciding with meteorological changes and the hot periods of the year. The estuary was constantly faecally polluted, coupled with high rates of infection of shellfish by V. parahaemolyticus 42 (13.6%), V. cholerae non-01 29 (9.4%) and V. alginolyticus 22 (7.1%), thus posing a health risk. The observed seasonal variability and prevalence of Vibrio species infection are of epidemiological significance, and provide a guide for effective control of associated cholera epidemics.
