Campylobacter Spp. Bone and Joint Infection: a Retrospective Cohort Study
Campylobacter bacteria, a Gram-negative bacillus commensal in the digestive tract of many animals and mainly responsible for human infections with digestive origins, has been little studied in the field of osteoarticular infections (OAI). Campylobacter spp. are, however, well described, mainly for C. fetus, and pose a dual therapeutic problem: i) a capacity for persistence due to the capacity of most strains to form biofilm; and ii) potential resistance to many antibiotics. The management of IOA caused by Campylobacter spp. is not codified, and is based on small series of cases reported in the literature.
• \> 18 years
• Osteoarticular infection (whatever its type), mono or polymicrobial with Campylobacter spp., diagnosed between 01/01/2013 and 12/31/2022:
• Septic arthritis: compatible clinical signs + joint fluid sample positive in culture and/or PCR positive for Campylobacter
• Spondylodiscitis: clinical signs and MRI compatible + blood cultures and/or disco-vertebral biopsy puncture positive in culture and/or PCR positive for Campylobacter
• Osteitis/osteomyelitis: compatible clinico-radiological picture + bone sample (biopsy or intraoperative sample) positive in culture and/or positive PCR for Campylobacter
• Infection on joint prosthesis or osteosynthesis equipment: documented Campylobacter infection and meeting the definition of probable or confirmed JIBS infections
