Present study consists the incidence of enteric bacteria in the Kapidag Peninsula. Nine sampling stations were selected and taken seasonally from 2011-2012. Presence of Escherichia coli was noted at all stations, except K1 and K6, throughout the sampling period irrespective of season. K1 and K6 stations (utilised as public beaches during the summer months) and depths below 30m displayed distinct genetic profile suggestive of diverse community of enteric bacteria other than E. coli. Analysis of uidA gene showed temporal and spatial genetic homogeneity in these E. coli populations. Ability to characterize E. coli communities might not only facilitate the mitigation of fecal pollution on Kapidag Peninsula, but also address the impact of environmental disturbances and seasonal and spatial variation on pathogen indicators.
