Abstract
Background: Wound infections with Staphylococcus aureus strains, a potential health care problem, especially after methicillin-resistant Staphylococcus aureus (MRSA) occurrence, which poses a significant challenge for healthcare workers. Objective: is to identify the relationship between the existence of the gene mecA within isolated bacterial cells and the phenomenon of multiple antibiotic resistance profiles of these strains. The study also explored the potential therapeutic activity of river water bacteriophage. Methodology: Among other bacterial species isolated from wound infections, 34 strains of S. aureus were isolated. After the screening for mecA gene using the Polymerase Chain Reaction Technique (PCR), the antibiotic susceptibility profiles of S. aureus isolates were determined by the disk diffusion method to identify the relationship between the two parameters. Furthermore, the possibility of Bacteriophage existence against isolated S. aureus was investigated. Results: A strong correlation between the existence of the gene mecA and the phenomenon of multiple antibiotic resistance profiles, particularly beta-lactams as well as commonly prescribed antimicrobial agents was present. Moreover, the results of the bacteriophage spots showed the possible presence of bacteriophage against S. aureus wound isolates. Conclusion: There was significant relationship between bacterial possessing of gene mecA, their biofilm production ability and their multidrug resistant phenomenon. River water bacteriophage could be used to treat pathogen bacteria included in this study.
