- Prevotella bivia is an anaerobic, non-pigmented, Gram-negative bacillus species that is known to inhabit the human female vaginal tract and oral flora. It is most commonly associated with endometritis and pelvic inflammatory disease.1, 2
- Rarely, P. bivia has been found in the nail bed, chest wall, intervertebral discs, and hip and knee joints.1 The bacteria has been linked to necrotizing fasciitis, osteomyelitis, or septic arthritis.3, 4
- Only 3 other reports have described P. bivia infections in the upper extremity with one patient requiring amputation2, and one with deep soft tissue infection requiring multiple debridements and extensive tenosynovectomy.5
- Delays in diagnosis are common due to P. bivia’s long incubation period and association with aerobic organisms that more commonly cause soft tissue infections leading to inappropriate antibiotic coverage.
- Here we present a case on P. bivia that resulted in extensive tenosynovectomy, multiple irrigations and debridements and eventually amputation of the 4th ray and digit of the hand.
