Prevotella

Bacteria of the genus Prevotella are gram-negative anaerobic fermenting rods related to the genus Bacteroides'. Individual species include P. oris, P. buccae, P. dentalis, and P. melaninogenica. Diseases caused by these bacteria include infections of the wound, urinary tract and respiratory tract (angina, sinusitis); they can also be infectious agents in the formation of abscess' in the oral cavity, for example after a human bite. The production of betalactamase makes them resistant to beta-lactam antibiotics.
