Whole-genome sequence analyses reveal cryptic species-level diversity among clinical Actinotignum isolates misidentified by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry

ABSTRACT Actinotignum schaalii is a human commensal bacterium that is well-known for causing urinary tract infections, predominantly in the elderly. However, reliable identification of A. schaalii in routine clinical microbiology has been challenging, mainly due to its fastidious growth and identifi...
