The aim of the present research was to assess the resistance to antibiotitcs of enterotoxigenic Escherchia coli (ETEC) from surface water, sediment, crab and fish. The genes (elt and est) of ETEC were assessed by duplex PCR using specif primers. The antimicrobial resistance of the isolates was conducted according to the method of disc diffusion on Mueller Hinton agar. Fifty six (56) isolates were identified as ETEC strains. The resistant were 9.7% for amoxicillin, 3.3 % for amoxicillin / clavulanic acid, 19.4% for chloramphenicol, 1.7% for nalidixic acid and 13% for tetracycline. No resistance of the strains was observed with the different antibiotics: imipenem, cefotaxime, ceftriaxone, aztreonam, gentamicin and colistin. The presence of antibiotic-resistant strains of E. coli indicates that other antibiotic-resistant fecal bacteria may be present.
