Antimicrobial resistance is one of the major threats to public health affecting humans, animals, and the environment. Potential transmission of multidrug-resistant zoonotic pathogens from chicken meat to humans is of particular concern. The aim of our research was to determine the antibiotic resistance patterns in Escherichia coli and Klebsiella pneumoniae strains isolated from chicken meat originating from markets and family farms in Novi Sad, Serbia. This study included 21 bacterial strains isolated from 31 chicken meat sample. For the antimicrobial susceptibility testing of the bacterial isolates the disc diffusion method was used according to EUCAST guidelines. Highest resistance was observed to ampicillin (66.66%), followed by amoxicillin with the addition of clavulanic acid (42.86%), and sulfamethoxazole with trimethoprim (19.05%), with the lowest resistance to ceftriaxone and gentamicin (4.76%). No isolates were resistant to cefuroxime and ciprofloxacin. Extended-spectrum β -lactamases (ESBL) were detected in only one sample (4.76%) identified as K. pneumoniae. Multidrug-resistant strains were not found. Considering the small number of samples included in this research, further studies are needed with a larger number of samples and other classes of antibiotics in order to gain a clearer picture on the abundance and prevalence of antibiotic-resistant enteric bacteria isolated from food od animal origin for human consumption in Serbia.
