Paronychia Due to Prevotella bivia That Resulted in Amputation: Fast and Correct Bacteriological
Diagnosis Is Crucial

Prevotella bivia is mainly associated with endometritis. The case of a patient with paronychia in a thumb due
to P. bivia resulting in osteitis and amputation is reported. The species was not acknowledged in the first
bacterial culture 2 weeks before surgery.

Infection of a Total Hip Arthroplasty With Prevotella Loeschii.   

Infection is a serious complication of total hip replacement. It has been proposed that 6% of all infections after total
hip arthroplasty may be of dental origin through hematogenous spread. However, no conclusive evidence that the
mouth is a definitive source for infection of a total hip replacement has been reported. In the current case, Prevotella
loeschii, a pigmented bacteroides species was identified in a total hip replacement. Prevotella loeschii is an organism
which exclusively inhabits the dental region. Hematogenous spread of Prevotella loeschii may occur after penetration
of the mucosal barrier in cases of endodontic or periodontic lesions, pericoronitis, or complications of tooth
extraction. The involvement of Prevotella loescheii in an infection in a patient who had a total hip arthroplasty is
strong evidence for the mechanism of a hematogenous infection from a dental source.

Pyogenic vertebral osteomyelitis caused by Prevotella intermedia

We describe a case of vertebral osteomyelitis caused by Prevotella intermedia, which is an extremely unusual cause
of vertebral osteomyelitis. The organism was isolated from vertebral biopsies and the patient was treated
successfully with intravenous ampicillin-sulbactam and clindamycin. Diagnosis and management of this condition are
described, and the importance of anaerobic bacteria in the pathogenesis of vertebral osteomyelitis is discussed.
