Identification and antimicrobial profile of bacteria isolated from urine of pregnant women treated in the Irmandade da Santa Casa de Misericórdia de Prudentópolis, Paraná

Abstract

Urinary infections are the most common ones during pregnancy, being favored by the physiological and anatomical changes that occur in pregnant women.  Having in mind the risks that such infections represent to the mothers and their babies, and also the numerous failure in the treatment with antibiotics, which may result in bacterial resistance to these kinds of medicine, the aim of this work is to identify the causing agents of urinary tract infections in pregnant women assisted at the hospital called Irmandade da Santa Casa de Misericórdia in Prudentópolis, Paraná. It also aims at investigating the antimicrobial sensitivity to the following antibiotics: Ciprofloxacin, Nitrofurantoin, Gentamicin, Norfloxacin, Ampicillin and Oxacillin, with basis on urine samples by pregnant women assisted at the Irmandade da Santa Casa de Misericórdia de Prudentópolis, Paraná. Fifty samples of urine were analyzed and a prevalence of 90% of Escherichia coli and 10% of Proteus mirabilis were found. These bacteria presented higher sensitivity to the antibiotics Ciprofloxacin, Nitrofurantoin, Norfloxacin and Gentamicin. Similar results were obtained in research carried out by other authors. E. coli is still the most isolated bacterium in urinary infections in pregnant women. Therefore, it is essential to highlight the importance of an antibiogram to guarantee the efficiency of the treatment.
