title: Urinary tract infections. 1. Pathophysiology and diagnostic approach.
abstract: Fecal flora have constant potential for access to the urinary tract in sexually active females, but fortunately urine is an unfavorable milieu for their proliferation. When urinary tract infection does occur, it can be difficult to eradicate in susceptible hosts. Most urinary tract infections involve common aerobic Gram-negative coliforms or the enterococcus. Diagnosis is based on Gram stain and/or culture of the urine; pyuria is a useful finding in that it corroborates the results. The location of infection in the urinary tract can be determined from the symptoms and results of the antibody-coated bacteria test or the amoxicillin localization test.
