Antimicrobial resistance (AMR) is a growing global public health concern. This study aimed to investigate the presence of bacteria and antibiotic resistance genes in the environment, more specifically in sewage and bioaerosol samples collected at a Wastewater Treatment Plant (WWTP). Bacterial species were identified and tested for antibiotic sensitivity. In addition, bla CTX-M, bla SHV, bla TEM and bla KPC genotypes, including those related to resistance to carbapenems, were detected by PCR. The results of this research are extremely important for understanding the mechanisms involved in antimicrobial resistance and for preventing the dissemination of these antibiotic-resistant microorganisms. This study contributes to the identification of sources of antibiotic resistance in the environment and implementation of AMR control and prevention strategies while preserving the effectiveness of antibiotics and public health.

  • AMR Focus: Addressing antibiotic resistance in sewage to combat AMR.

  • Broad Study: Research covers sewage, sludge, and bioaerosols for a holistic view.

  • PCR for Resistance: Molecular detection of major resistance genes.

  • Pathogenic Bacteria: Identifies Klebsiella and E. coli.

  • Urgency in Control: Emphasizes the need for immediate bioaerosol control.
