Diarrheogenic Escherichia coli (DEC) is an important agent of waterborne gastrointestinal infections. The objective of this work was to evaluate the microbiological and physico-chemical quality of 58 freshwater groundwater samples for the consumption of a rural settlement and to characterize the E. coli isolates, genotyped within the DEC pathophyses, by the PCR technique, and phenotypically. All water samples presented contamination with total coliforms, and 36 (62.1%) with E. coli. In HEp-2 cells, of 170 E. coli isolates, 106 (62.36%) showed AA, 15 (8.82%) AD, 17 (10%) noncharacterized adhesion and 32 (18.82%) were non-adherent. As for biofilm formation, 126 (74.12%) strains are forming, and 44 (25.88%) did not form biofilm. DEC was identified in 6.89% of the water samples with E. coli: three (5.17%) with enterotoxigenic E. coli (ETEC), and one (1.72%) with enteroaggregative E. coli (EAEC). EAEC showed aggregative adherence, whereas various ETEC strains presented diffuse, aggregative, and non-defined adherence. All DEC strains were biofilm forming. Two isolates of ETEC showed resistance to ampicillin and tetracycline, and one isolate showed resistance to aminoglycosides. The EAEC isolate was sensitive to all antibiotics tested. All ETECs were classified into phylogenetic B1 and EAEC in E. The serotypes identified in our study were: O24:H21, ONT:H21, O17:H46, and O6:H12. All water samples were within normal fluorine parameters; however, measured turbidity was above the permitted standard in 13 (22.4%) samples. The presence of E. coli and DEC in water samples indicates the need to take action to prevent contamination of water resources accessed by people to prevent the transmission of diseasesDownloads
