Escherichia coli sensitivity was investigated with the disc diffusion test for: ampicillin, amoxicillin with clavulanic acid, tetracycline, chloramphenicol, gentamicin, and ceftriaxon, sulphamethoxasole with trimethoprim, ciprofloxacim, and florfenicol. E. coli strains resistant to three or more antibiotics were tested by means of agar dilution method for ciprofloxacim, tetracycline, chloramphenicol, gentamicin and amoxicillin with clavulanic acid by determination of the minimum inhibitory concentration (MIC). The tested E. coli resulted resistant to all antibiotics and chemotherapeutics with the exception of ceftriaxon and florfenicol. The highest resistance incidence (87.5%) was to tetracycline in E. coli strains isolated from pigs, 60% for E. coli strains isolated from cattle, 56% isolated from poultry, and 20% originating from dogs. E. coli strains isolated from cats were sensitive to tetracycline. The highest incidence of ampicillin resistance was determined for E. coli strains originated from poultry (78%).
