Abstract

Urosepsis due to Aerococcus urinae is rare in clinical settings with only a few of reported cases worldwide by 16S rRNA sequencing. Here we report a case of sepsis caused by A. urinae in a 86 year-old male with complicated urinary tract infection which was confirmed through peptide mass fingerprinting of matrix-assisted laser desorption ionization time of flight mass spectrometry.
