Prevalência e perfil de susceptibilidade aos antimocrobianos de micro-organismos recuperados de infecção do trato urinário de pacientes ambulatoriais

Abstract

The urinary tract infections are a major public health problem at present and they are the second most common cause of infections in the world population, both in nosocomial infections and in the community. It is a clinical syndrome with high incidence, predominantly in women, being often empirically treated. In this study 381 urine cultures results from outpatients attended at the Clinical Laboratory of the Faculdade de Farmácia da Universidade Federal de Minas Gerais, from August 2006 to November 2008, were analyzed. The most common etiologic agents were identified and antimicrobial susceptibility profile of 26.8% positive urine cultures were of female patients aged 16 to 40 years. The most prevalent microorganisms were Gram negative, especially Escherichia coli (78.4%) followed by Klebsiella spp (5.9%) and Proteus spp (3.9%). Antimicrobials used in empirical treatment protocols were tested, the susceptibility profile of more frequently microorganisms were traced and showed the importance of establishing routine to evaluate patterns of local resistance among urinary pathogens and the need to review the protocols of empirical therapy employed.
