Abstract

Aerococcus urinae is a gram-positive coccus that produces alpha-hemolysis on blood agar and is negative for catalase. A. urinae can often be misidentified as a streptococcus, staphylococcus, or enterococcus by most commercial identification systems. Although A. urinae is a rarely reported human pathogen, it can be fatal in some cases. Here we report on a case of urosepsis caused by A. urinae, identified by 16S rRNA gene sequencing in a patient with ureter stones and hydronephrosis, for the first time in Korea. It is important for physicians to consider A. urinae as a potential pathogen and to prescribe the most suitable antibiotics to ensure the best outcome.
