In-vitro activity of fosfomycin trometamol and some other antibiotics against Escherichia coli strains isolated from urinary tract infections
Journal Title: Dicle Tıp Dergisi - Year 2011, Vol 38, Issue 3
Abstract
In recent years, in our country and the world, susceptibility of uropathogenic E.coli strains to commonly used antibiotics in the treatment of urinary tract infections has decreased. That decreased susceptibility has been caused to treatment failure, need to change the empirical treatment, increase in prescription costs, prolongation of hospital stay, increased social costs, increased morbidity and mortality. In this study, determination of susceptibility to different variety of antibiotics and fosfomycin in urinary tract infection isolate E.coli were aimed. Materials and methods: The study included E.coli positive urine samples which had been sent to State Hospital Central Laboratory in Kızıltepe between August 2010 and December 2010. These isolates were obtained from patients who have microscopically 10/mm3 leukocyte in urine. In this study, we tested susceptibility of isolated E.coli to FOT (Fosfomycin), CIP(ciprofloxacin), IP (İmipenem), TZP (Piperasilin-Tazobactam), CAZ (Ceftazidim). According to CLSI criteria, susceptibility testing was performed by Kirby-Bauer disc diffusion method. Results: E.coli strains isolated from urine samples examined between August 2010 and December 2010, all were susceptible to fosfomisine. The resistance rates of E.coli strains to Ceftazidim, Ciprofloxacin, İmipenem, Piperacillin-Tazobactam were found respectively 33.3%, 49.1%, 36.8%, 45.6% (Table 1). Conclusions: Because of the high susceptibility rates of fosfomycin at community-acquired urinary tract infection, it can be preferred to the non-complicated urinary tract infections as an antimicrobial agent.
