Abstract: Actinotignum schaalii is an emerging uropathogen; however, routine culture protocols and usual phenotypic methods do not allow for easy detection and identification. Herein, we report the first Korean case of urinary tract infection caused by A. schaalii in a 79-year-old patient with prostate cancer. A gram-positive rod bacterium was isolated from the patient's urine after 2 days of culture and identified as A. schaalii using matrix-assisted laser desorption/ionization time-of-flight (MALDI-TOF) mass spectrometry and DNA target sequencing.
