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.

Campylobacter species are common causes of diarrheal illness following consumption of contaminated food or unpasteurized dairy products, but subsequent dissemination and joint space infections are rare. We describe a patient who consumed undercooked chicken wings, with subsequent development of a febrile gastrointestinal illness marked by copious, watery stool output. This was followed by acute onset of pain and inability to bear weight on his right hip and leg where he had undergone prior arthroplasty. Synovial fluid cultures revealed Campylobacter coli, identified utilizing matrix-assisted laser desorption/ionization time-of-flight mass spectrometry. The patient made a full recovery following hip joint space debridement with prosthesis retention, coupled with sequential intravenous and oral ciprofloxacin therapy. This case highlights both the potential for prosthetic joint infection with Campylobacter coli following diarrheal illness, as well as challenges in reducing Campylobacter contamination within commercially distributed chicken wings.

During the coronavirus disease 2019 (COVID-19) pandemic, many public response activities were conducted outdoors to reduce the risk of transmission. This was in adherence to existing infection prevention recommendations. We report the development and safe, efficient operation of a mass COVID-19 vaccination clinic during a time when guidelines for indoor clinics were limited.
