The aim of this study was to know the quality of water and some of the fish from Fresco lagoon, a RAMSAR site. In total, 376 samples including 216 water samples and 160 fish (viscera and gills) were collected in six sites and lagoon respectively. They analysed by the standard microbiological test for Escherichia coli isolation. Identification and phylogenetic affiliation of E. coli were performed by PCR. In water, 338 strains of E. coli were isolated. From fish, 86 (53.75%) E. coli were isolated from the viscera and 74 (46.25%) from the gills. In water and fish, the phylogenetic group A was the most frequent (69.82% and 81.25%, respectively), followed by the group B1 (23.67% and 13.75%, respectively). The group B2 was rare in water (4.44%) and fish (5%) while D (2.07% in water) was absent in fish. Strains of groups B2 and D are usually more pathogenic than A and B1 and they are frequently responsible for extra-intestinal infections. Our findings indicate that Fresco lagoon could represent a potential reservoir of extra-intestinal infections for the riverine populations and consumers.
