Title

CHARACTERIZATION OF STAPHYLOCOCCUS AUREUS BIOFILM FORMATION IN URINARY TRACT INFECTION

Pages

  0-0

Abstract

 Background: The aim of this study was to investigate the antibiotic susceptibility pattern as well as the phenotypic and genotypic BIOFILM FORMATION ability of STAPHYLOCOCCUS AUREUS isolates from patients with URINARY TRACT INFECTION (UTI).Methods: A total of 39 isolates of S. aureus were collected from patients with UTI. The antibiotic susceptibility pat-terns of the isolates were determined by the Kirby-Bauer disk-diffusion. We used the Modified Congo red agar (MCRA) and Microtiter plate methods to assess the ability of BIOFILM FORMATION. All isolates were examined for deter-mination of biofilm related genes, icaA, fnbA, clfA and bap using PCR method.Results: Linezolid, quinupristin/dalfopristin and chloramphenicol were the most effective agents against S. aureus isolates. Overall, 69.2% of S. aureus isolates were biofilm producers. Resistance to four antibiotics such as nitrofuranto-in (71.4% vs.28.6%, P=0.001), tetracycline (57.7% vs.42.3%, P=0.028), erythromycin and ciprofloxacin (56% vs.44%, P=0.017) was higher among biofilm producers than non-biofilm producers. The icaA, fnbA and clfA genes were present in all S. aureus isolates. However, bap gene was not detected in any of the isolates.Conclusion: Our findings reinforce the role of BIOFILM FORMATION in resistance to antimicrobial agents. Trimethoprim-sulfamethoxazole and doxycycline may be used as an effective treatment for UTI caused by biofilm producers S. aure-us. Our results suggest that BIOFILM FORMATION is not dependent to just icaA, fnbA, clfA and bap genes harbor in S. aureus strains.
