Successful Treatment of Olecranon Bursitis Caused by Trueperella bernardiae: Importance of Environmental Exposure and Pathogen Identification

摘要

A livestock farmer with a history of arthropathy presented with unilateral olecranon bursal swelling and tenderness. Multiple wound and intraoperative cultures revealed growth of Trueperella bernardiae, a Gram-positive coccobacillus, with symptom resolution following appropriate antimicrobial therapy. To our knowledge, this is the first case report of olecranon bursitis caused by this organism. Coryneform bacteria are often regarded as contaminants in clinical cultures, but advanced techniques for species identification may reveal expanded pathogenic potential of individual species like T. bernardiae and elucidate epidemiologic clues for osteoarticular infections in these cases.
