Characterization of genes involved in the iron acquisition system of multidrug-resistant Acinetobacter baumannii

Abstract

Background: The high prevalence of virulence-associated genes observed in isolates underscores the pathogenic potential of this bacterium. The presence of these genes confers enhanced survival, evasion of host defenses, and increased virulence. In this study, we investigate the presence and distribution of genes associated with virulence and assess the antimicrobial susceptibility patterns in clinical isolates of .Materials and method: This research focused on examining the 5ulti-drugs resistant (MDR) strains that were included in this investigation. The identification of these strains was validated using Oxa-51. The presence of the and genes was determined through conventional PCR techniques.Results: The results derived from Oxa-51 PCR confirmed the identification of all 50 selected strains of . Additionally, both the and genes were successfully identified in 82% of the MDR strains.Conclusion: Moreover, the varying antibiotic resistance patterns highlight the challenge in treating infections effectively. Strategies such as combination therapy, antimicrobial stewardship, and infection control measures should be considered to combat this multidrug-resistant pathogen.
