Abstract: This study aims at the Microbiological and Physicochemical Characterization of the Bathing Waters of Atlantic Ocean Beaches of Grand Bassam in Côte d’Ivoire. Waters Sampling campaigns were carried out from December 2017 to December 2018 with a monthly sample per water point (Azuretti-village and “France” neighborhood). The analysis focused on assessment of eight (8) bacteria and parasites and the determination of twenty-eight (28) organoleptic and physicochemical parameters. The results of the physicochemical assays showed that these waters were strongly mineralized with a mean of 47.3mS/cm at Azuretti-village and “France” neighborhood. Microbiological analyses revealed presence of total coliforms (TC), thermo-tolerant coliforms (THC), Escherichia coli, Enterococcus faecalis, Pseudomonas aeruginosa, yeasts and molds. The bathing water of on the Azuretti-village beach are conform according to the Ivorian reference system (CT and CTH are respectively less than 10,000CFU/100ml and 2,000CFU/100ml) throughout the campaign, only one non-compliance is noted in August on the beach of “France” neighborhood. Regarding the Algerian standard taken in addition to Ivorian criteria, the number of E. faecalis bacteria must be less than 100CFU/100ml. Based on this standard, both ranges exhibited total coliform and heat-tolerant conformities throughout the study period and did not comply with E. faecalis during the months of January to February 2018 and from June to September 2018. The Canadian and American standard stipulates only the geometric mean of E. faecalis which must be lower than 35. In view of this standard, these waters present 54% of non-compliance in the “France” neighborhood and 62% of non-conformities in Azuretti-villages during the months of January to February 18 and from June to October 18. According to Algerian and Canadian standards, the bathing waters of both beaches are unsatisfactory microbiological qualities during dry and rainy periods.

Abstract: Waters used for recreational activities in order to ensure the health of populations who practice their recreational activity. Disease or infection risk associated with recreational water areas is mainly related either to faecal contamination or to domestic or hospital effluents. The present study aimed assessment of microbiological contamination of surface waters (rivers and lake) of three cities in southern Côte d’Ivoire used for recreational activities, by bacteria generally found in humans and animal’s digestive tract, and then assesses their resistance to commonly antimicrobial drugs used in human therapy. Water samples have been taken from different identified sites over a 13-months period. A microbiological analysis based on numbering of germs was performed then isolated strains were assayed for antibiotic sensitivity tests. Data analysis was performed using SPSS 22.0 software. Results have shown the presence of Escherichia coli, Pseudomonas aeruginosa and Enterococcus faecalis in waters analysed. E. coli, a faecal contamination marker, was present in all the analysed waters with levels higher than standards defined by the 2006/7 /EC European Directive for bathing water, making them unsuitable for swimming. E. coli strains showed high levels of resistance to amoxicillin, ticarcillin, nalidixic acid and cotrimoxazole. Moreover, a beta-lactamase producing strain was isolated, suggesting probability of contamination by hospital or domestic effluents. The results of this study show the importance of microbiological monitoring of surface.
