Title

Molecular Characteristics of Biofilm-Producing Methicillin-Resistant Staphylococcus epidermidis Isolates Causing Urinary Tract Infections

Pages

  0-0

Abstract

 Background: Coagulase-negative Staphylococcus epidermidis is the most prevalent member of the human skin normal biota that plays an important role as a common cause of catheter and prosthetic device-related infections from, for example, indwelling catheters. Objectives: This study aimed to characterize the clonality of Biofilm-producing methicillin-resistant S. epidermidis (MRSE) strains isolated from Catheterized Patients with urinary tract infection at a referral hospital in Tehran, Iran. Methods: Between 2014 and 2016, a total of 56 methicillin-resistant S. epidermidis (MRSE) strains were recovered from Catheterized Patients. The MRSE isolates were tested for Biofilm formation and different genes involved in this process were detected. Clonal dissemination of MRSE isolates was determined using the combination of pulsed-field gel electrophoresis (PFGE) and SCCmec typing. Results: Out of the 56 MRSE strains, 50 (89%) formed Biofilm and were positive for icaA and icaD genes, and 73% (n = 41) harbored IS256. The PFGE patterns revealed a total of 32 different pulsotypes consisting of 16 single types (STs), 16 common types (CTs), and 2 SCCmec types (III and IV) were detected. Moreover, all STs carried SCCmec type IV and classified as community-acquired strains. Four CTs were common among Biofilm and non-Biofilm producing strains. Conclusions: The presence of icaA and icaD genes with a high prevalence of IS256 element in clonal groups of MRSE strains suggests that ica, IS256, and Biofilm forming ability occur simultaneously in specific S. epidermidis clones and spread preferentially in hospitals and community.
