Abstract

Pelvic actinomycosis-like disease due to Propionibacterium propionicum has been very rare and only a few cases have been reported in the literature. We herein report a probable first case of a psoas abscess caused by P. propionicum. Since P. propionicum is indistinguishable from Actinomyces israelii by morphological features or routine biochemical tests, 16S rRNA gene sequencing was useful to discriminate these two species in this case.

Keywords: 16S rRNA; Actinomycosis-like disease; Spider-form colonies.
