Tidal effect on the dispersion of fecal pollution indicator bacteria and associated health risks along the Kribi beaches (Southern Atlantic coast, Cameroon)

Assessment of fecal contamination indicator bacteria concentrations on beaches are important for health risk prevention and management. This study assessed temporal changes in bacterial abundances as a function tidal cycles seasons along the Kribi beaches, Cameroon. Overall, samples taken during low high tides different year showed that waters exposed to due presence coliforms (5–35 CFU/100 ml), total (100–600 Escherichia coli (0–15 Streptococcus feacalis (50–700 Pseudomonas aeruginosa (300–7200 Vibrio cholerea (5–250 parahemoliticus (0–115 Aerobic Mesophilic Heterotrophic Bacteria (99–875 ml). Regardless strain sampling site, cell were significant at rainy seasons. At each station (Mpalla, Ngoyè Mboamanga), depending cycles, correlations recorded between some strains environmental variables (P < 0.05).
