ANTIBIOTIC SUSCEPTIBILITY OF ESCHERICHIA COLI WILD STRAINS

Abstract

Escherichia coli is the normal microbe of the intestinal microflora but can cause different illnesses exception the intestinal tract. And the most problem of the illness with E. coli etiology is the rapid antibiotic resistance forming of the current pathogen. We had the aim to detect the antibiotic susceptibility of E. coli strains separated from the samples of the ill cattle in endometritis and mastitis. 12 types of antimicrobial preparations were tested. We have founded, wild E. coli strains were totally resistant to vancomycin, streptomycin, tetracycline, doxycycline, kanamycin, amoxicillin, and tylosin. Drugs of the cephalosporine range also were un-efficient. And just furazolidone, enrofloxacin, and gentamycin have shown the effective action to tested samples of E. coli. So, the testing of antibiotic susceptibility is the obligatory action in therapy-list formation. Just this action can demonstrate the efficient antimicrobial drugs that can provide the recovery of the illness animals.
