| Popis: | Introduction: Pseudomonas aeruginosa (P. aeruginosa) is a frequent nosocomial pathogen that causes severe diseases in many clinical and community settings. The objectives were to investigate the occurrence of multiple antibiotic resistant P. aeruginosa strains among clinical samples and to detect the presence of antibiotic resistance genes in the DNA molecules of the strains.Methods: Clinical specimens were collected aseptically from various human anatomical sites in five selected health institutions within Kwara State, Nigeria. Multiple drug resistance patterns of isolated micro-organisms to different antibiotics were determined using the Bauer Kirby disc diffusion technique. The DNA samples of the multiple resistant P. aeruginosa strains were extracted and subjected to Polymerase Chain Reaction (PCR) for resistance gene determination.Results: A total of 145 isolates were identified as P. aeruginosa from the clinical samples. Absolute resistance to ceftazidime, gentamicin and ceftriaxone was observed while low resistance to ciprofloxacin, piperacillin and imipenem was documented. The prevalence of bla VIM , ,bla CTX-M and blaTEM were 34.4 %, 46.7 % and 16.7 % respectively.Conclusion: This study has shown that there is a high occurrence of metallo â-lactamase- producing and antibiotic-resistant strains of P. aeruginosa in clinical specimens from the studied area. Keywords: Metallo â-lactamase enzyme, P. aeruginosa, clinical samples, antibiotic-resistance genes |
