Seasonal prevalence of cholera pathogen (Vibrio cholerae) in water and plankton samples in the southern coastal part of Bangladesh


In the present study seasonal prevalence of Vibrio cholerae, serogroup O1 and O139 (VC O1 and O139) were investigated in several water bodies of southern coastal area adjacent to the Bay of Bengal. The study revealed that the gross total counts of both VC O1 and O139 in water were 2.2×107 cfu/L and 5.0×106 cfu/L which were the highest followed by zooplankton sample with 7.0×105 cfu/L and 4.6×105 cfu/L and phytoplankton sample with 4.0×105 cfu/L and 3.4×105 cfu/L, respectively. It was also revealed that VC O1 counts were appeared to be higher in all types of samples than that of VC O139 throughout the investigation period and summer counts were found to be higher than that of monsoon and winter counts.
