Anaerobic Thioglycolate Broth Culture for Recovery of Propionibacterium acnes from Shoulder Tissue and Fluid Specimens

Propionibacterium acnes is an agent of shoulder infection, especially postsurgically ([1][1], [2][2]). The study by Butler-Wu et al. suggests a minimum culture incubation of 13 days for recovery of P. acnes from periprosthetic tissues and fluids ([3][3]). Methods for recovery of anaerobes vary, and
