Abstract
This review summarizes the information that supports the potential importance of anaerobic bacteria in the pharyngo-tonsillitis (PT) associated with infectious mononucleosis (IM). Evidence supportive of the potential of involvement of bacteria in IM was provided by several studies that showed increased recovery of bacteria on the tonsillar surfaces in IM. Several studies demonstrated that metronidazole therapy alleviated the clinical symptoms of tonsillar hypertrophy and shortened the duration of fever in IM. Metronidazole has no antimicrobial activity against aerobic bacteria and is only effective against anaerobic bacteria. A possible mechanism of its action is the suppression of the oral anaerobic flora that might contribute to the inflammatory process induced by the Epstein-Barr virus. This explanation is supported by the increased recovery of Prevotella intermedia and Fusobacterium nucleatum from the tonsillar surfaces during the acute phases of IM and an immune response against these organisms by patients with IM. Although more studies are needed, these findings support the possible pathogenicity of Gram-negative anaerobic bacteria in the PT associated with IM.
