Prevalence and Antimicrobial Resistance Pattern of Escherichia Coli Isolates from Postpartum-Urinary Tract Infections

Aims The aim of our study was to determine the prevalence of Escherichia coil strains, isolated from urine cultures of breastfeeding women hospitalized in the Obstetrics and Gynecology department of a Western Romanian hospital, and their resistance patterns, in particular to betalactam antibiotics. Methods Identification of germs and extensive antimicrobial tests (by dilution antimicrobial susceptibility tests) were done with the help of the automatic Vitek 2C (bio-Merieux) analyzer. Results We isolated 167 microbial strains with hospital acquired potential of 309 urines samples, from which 128 (76.65%) were Escherichia coli. These strains have been most commonly resistant at aminopenicillines and I-II generation cephalosporins. All these strains associated other resistance phenotypes as well. Conclusions The high prevalence of Escherichia coli strains resistant to antimicrobial agents isolated in our study, enforces a proper surveillance of medical staff and a rational necessity to improve our antibiotic policy.
