Abstract

Hospital-related infections, particularly from intensive care units, are brought about by the bacteria Pseudomonas aeruginosa. Because it is resistant to drugs and may exist in hospitals, it can be hard to kill off. Because of this, it creates a significant risk and challenge in hospital situations. The chemical and genetic traits of Pseudomonas aeruginosa, most notably its beta-lactamase synthesis and antibiotic resistance, have been part of several studies performed in the Al-Diwaniyah Province. One of the more crucial phases when developing antimicrobial tactics is identifying the biological indicators associated with antibiotic-resistant bacteria. While Pseudomonas aeruginosa had been isolated from a number of clinics in past studies, here remains not many assets available for its molecular characterization and resistance patterns. Finding out more on a generalization of genes associated with resistance like GES, blaOXA-48, and SPM can help build approaches for managing bacterial infections. Using traditional molecular techniques, this study sought to obtain and determine Pseudomonas aeruginosa from medical samples, investigate its capacity to resist drugs, and identify its presence of genes that create beta-lactamases. Findings: 15 out of 30 clinical specimens (50%) had Pseudomonas aeruginosa confirmed. Burns (60%), wounds (26.6%), and urine (13.4%) had the greatest isolation rates. 60% of the isolates produced beta-lactamase, suggesting that they were resistant to a lot of antibiotics with the notable exception of tigecycline, as determined by the Rapid Iodine Assay and the Vitec II 2 system. The PCR method revealed that the 16S rRNA gene was found in all isolates. In addition, 20% had the SPM gene, 40% had the blaGES gene, and 75% had the OXA-48 gene. This study is one of the first to explain Pseudomonas aeruginosa’s molecules in the Diwaniyah Province focused on the genetic factors that lead to its heightened resistance and production of beta-lactamases. we are consequences, To avoid the development of drug-resistant Pseudomonas aeruginosa in healthcare environments, findings show the urgent importance for ongoing surveillance, strict infection control procedures, and antibiotic control programs.
