Ethiology of urinary tract infections in male

摘要

The present study is based on data from 4317 positive urine cultures collected at S. Orsola, Fondazione Poliambulanza Hospital of Brescia (Italy) from 2007 to 2009.The patient group was heterogeneous and included in- and outpatients of both gender, ranging in age from 1 to 99 years. E. coli was the most frequently pathogen isolated in all the urine cultures independently from age or sex. Our findings differ from those of a similar study made in the U.S.A., where Enterococcus (Group D Streptococcus) was the most frequently isolated pathogen in the urine cultures of the male subjects. These results suggest to maintain an identical empirical therapy in male and female because the most frequently isolated bacteria responsible of urinary tract infections are Gram negative.
