Abstract

This study investigated the genetic basis of antibiotic-resistant bacteria. The antibiotic susceptibility of Escherichia coli, Staphylococcus aureus, and Klebsiella pneumoniae strains isolated from clinical samples was determined, and the presence of resistance-related genes in their genomes was assessed using the polymerase chain reaction (PCR) method. The results revealed the widespread presence of resistance genes — blaTEM, mecA, vanA, and aac(6’)-Ib — among the bacterial strains. These findings are crucial for understanding the mechanisms of antibiotic resistance and improving strategies for the treatment of infectious diseases.
