A polymicrobial flora is isolated from peritonsillar abscesses (PTAs). Predominant organisms are the anaerobes Prevotella, Porphyromonas, Fusobacterium, and Peptostreptococcus species. Major aerobic organisms are GABHS, S aureus, and H influenzae.

Uhler et al, in an analysis of data from 460 patients with PTA, found a higher incidence of the condition in smokers than in nonsmokers. [6]
