Abstract

Aerococcus viridans is a rare pathogen in humans, with only six cases of A. viridans urinary tract infections reported worldwide. Nosocomial urinary tract infections with bacteremia caused by A. viridians are even rarer, with no prior reports of urosepsis caused by A. viridans occurring in the Republic of Korea. Here we report a case of urosepsis caused by A. viridans in a 79 year-old female nursing home resident. The patient was admitted to the hospital presenting a fever of 39degrees C, chills, and oliguria for two days prior to admission. Urine culture yielded a robust growth of 105 CFU/mL of A. viridians, with blood culture positive for the same organism. Following diagnosis, the patient was treated with ciprofloxacin intravenously for 2 weeks, resulting in clearance of the infection and a full recovery from urosepsis. Although A. viridans is rarely associated with human infections, this case shows that, under the right conditions, it can be responsible for severe infections like urosepsis.
