Abstract

In the present study, 25 Escherichia coli strains isolated from beef, pork, and poultry meat, and producing extendedspectrum β-lactamases (ESBL) (18 strains) or AmpC- cephalosporinases (7 strains) were tested for antimicrobial resistance using the minimum inhibitory concentration method with 16 antimicrobial agents. All examined strains were resistant to ampicillin and the first-generation cephalosporins. Variable resistance to the third-generation cephalosporins (40%-100% among ESBLproducing strains and 0-72% among AmpC-producing strains) was noted. Less than 30% of examined strains were resistant to ciprofloxacin. All isolates were susceptible to the fourth-generation cephalosporins, cephalosporins connected with inhibitors of β-lactamases, carbapenems, and gentamycin
