A Case of Sepsis in a 92-Year-Old Korean Woman Caused by Aerococcus urinae and Identified by Sequencing the 16S Ribosomal RNA Gene.

Aerococcus urinae is an uncommon pathogen that was first identified in 1992. Herein, we report a case of bloodstream infection caused by A. urinae, which occurred in a 92-year-old Korean female patient with an underlying urologic infection who had altered consciousness. The blood culture yielded positive results for A. urinae; however, identifying A. urinae was challenging. Ultimately, we used 16S ribosomal RNA (rRNA) gene sequencing to identify the organism. The patient recovered after being treated with ertapenem and meropenem. To our knowledge, this is the first report of a case of A. urinae sepsis in South Korea. © American Society for Clinical Pathology, 2016. All rights reserved.
