Novel Fastidious, Partially Acid-Fast, Anaerobic Gram-Positive Bacillus Associated with Abscess Formation and Recovered from Multiple Medical Centers

We report a novel anaerobe causing abscess in four patients at three hospitals. In the clinical specimen, bacilli were branching, Gram positive, and acid fast. The organism grew slowly and was not identified by 16S rRNA sequencing. Our findings support the description of a new genus and species of the suborder Corynebacterineae.
