Cutibacterium Acnes: A Significant Pathogen in Shoulder-Replacement Surgery

Pdf Summary

The document discusses Cutibacterium acnes, previously known as Propionibacterium acnes, an anaerobic bacterium that is commonly regarded as a skin commensal organism but can also act as a pathogen in shoulder surgeries. The case study involves a 78-year-old man with chronic shoulder pain post shoulder arthroplasty, where C acnes was identified as the causative agent of infection. The challenges lie in distinguishing contamination from infection, the need for proper culture setup, and the necessity of prolonged incubation periods for recovery. Key points include the subtle clinical presentation of C acnes infections, laboratory findings, and the shift in predominant causative organisms in shoulder surgeries. The importance of communication between the laboratory and clinicians is emphasized to ensure timely and accurate diagnosis. It stresses the need for awareness of emerging pathogens and customized culture protocols. Overall, the document highlights the significance of proper identification and management of C acnes infections in shoulder surgeries to prevent treatment delays and improve patient outcomes.
