Environmental pollution is a serious problem that can cause sicknesses, fatality, and biological contaminants such as bacteria, which can trigger allergic reactions and infectious illnesses. There is also evidence that environmental pollutants can have an impact on the gut microbiome and contribute to the development of various mental health and metabolic disorders. This study aimed to study the antibiotic resistance and virulence potential of environmental Pseudomonas aeruginosa (P. aeruginosa) isolates in slaughterhouses. A total of 100 samples were collected from different slaughterhouse tools. The samples were identified by cultural and biochemical tests and confirmed by the VITEK 2 system. P. aeruginosa isolates were further confirmed by CHROMagarTM Pseudomonas and genetically by rpsL gene analysis. Molecular screening of virulence genes (fimH, papC, lasB, rhlI, lasI, csgA, toxA, and hly) and antibiotic resistance genes (blaCTX-M, blaAmpC, blaSHV, blaNDM, IMP-1, aac(6')-Ib-, ant(4')IIb, mexY, TEM, tetA, and qnrB) by PCR and testing the antibiotic sensitivity, biofilm formation, and production of pigments, and hemolysin were carried out in all isolated strains. A total of 62 isolates were identified as P. aeruginosa. All P. aeruginosa isolates were multidrug-resistant and most of them have multiple resistant genes. blaCTX-M gene was detected in all strains; 23 (37.1%) strains have the ability for biofilm formation, 33 strains had virulence genes, and 26 isolates from them have more than one virulence genes. There should be probably 60 (96.8%) P. aeruginosa strains that produce pyocyanin pigment. Slaughterhouse tools are sources for multidrug-resistant and virulent pathogenic microorganisms which are a serious health problem. Low-hygienic slaughterhouses could be a reservoir for resistance and virulence genes which could then be transferred to other pathogens.
