title: Acute Pyelonephritis with Bacteremia Caused by Enterococcus hirae: A Rare Infection in Humans.
abstract: Enterococci are one of the usual residents of the microflora in humans. In the last decade this genus has been reported as the third most common cause of bacteremia. We present the case of a 78-year-old female who was admitted to the emergency room because of nausea, lipothymia, and weakness. She was diagnosed with a pyelonephritis with bacteremia, with the isolation in blood and urine cultures of Escherichia coli and Enterococcus hirae. This last microorganism is a rarely isolated pathogen in humans. Currently it is estimated to represent 1-3% of all enterococcal species isolated in clinical practice.
