Abstract

Background and objective: Methicillin resistant Staphylococcus aureus (MRSA) has long been a common pathogen in healthcare facilities, but now, it has emerged as a problematic pathogen in the community setting as well. In this study we aimed to type all MRSA strains isolated from patients with urinary tract infection (UTI) in a hospital in Isfahan. Materials and methods: A total of 109 S. aureus isolates were collected from patients with UTI from a hospital in Isfahan, during 2016 and were identified at the species level using specific primers. All strains were tested for susceptibility to cefoxitin and the presence of mecA gene was evaluated among MRSA strains. Separate multiplex-PCR assays were employed for SCCmec typing, ccr typing and agr typing of strains. Results: Out of the 109 isolates which confirmed as S. aureus strains, 36 strains showed resistance to cefoxitin and harbored mecA gene. The results of SCCmec and ccr typing of MRSA strains showed the presence of SCCmec types III, IV and V and also types 2, 3 and 5 ccr, in which SCCmec type III and ccr type 3 were the dominant types among all. Moreover, MRSA strains were positive for agr types I-IV in which agr type I was the most frequent one. Conclusion: The results of this study indicating the presence of hospital acquired MRSA (HA-MRSA) strains among patients with UTI in the desired hospital. Strains with hospital origin usually show high resistance to different antibiotics and also have a variety of virulence factors which enable them to produce wide range of infections. The prevalence of such strains in the desired hospital could be an urgent for patient safety.
