A Bacteroides joint infection is an uncommon, severe form of anaerobic septic arthritis affecting the synovial fluid and articular tissues of the musculoskeletal system

It is caused by obligate anaerobic, Gram-negative bacilli of the genus *Bacteroides*—most frequently *Bacteroides fragilis*—and predominantly arises in older adults or immunocompromised individuals with underlying comorbidities, preexisting joint disease, or gastrointestinal pathology Pathogenesis typically involves hematogenous dissemination from an intra-abdominal, pelvic, or cutaneous focus, contiguous spread, or direct intra-articular inoculation Clinically, it manifests as acute or subacute...

It is caused by obligate anaerobic, Gram-negative bacilli of the genus *Bacteroides*—most frequently *Bacteroides fragilis*—and predominantly arises in older adults or immunocompromised individuals with underlying comorbidities, preexisting joint disease, or gastrointestinal pathology

Clinically, it manifests as acute or subacute monoarthritis characterized by joint pain, swelling, erythema, functional impairment, and purulent synovial effusions, posing a high risk for rapid cartilage destruction and permanent articular damage if not promptly addressed
