Abstract


Ten E. coli strains isolated from celulitis lesion s of Japanese quails were to evaluated antimicrobia l resistance to twent y six drugs , to pathogenicity of strains in SPF chickens embryonated eggs and virulence factors. The antimicrobials of higher efficiency wer e ampicillin, florfenicol and the lesser efficiency were erythromycin, oxacilin, lincomicin, novobiocin, penicillin, sulfonamidas, trimethoprim+sulfomethoxazo/e and tetracyicline. The majority of E. coli strains were serum resistance, the others virulence factors, hemolisin and congo red affinity, were lesser frequent on the studied strains. Pathogenicity of E. coli strains, evaluated to DL50 in embryonated eggs, had varied of 8x10 2 the 3,2x10
