Core tonsillar cultures for aerobic and anaerobic bacteria were performed on four normal tonsils removed from four children because of velopharyngeal insufficiency and on four tonsils removed from four children because of recurrent tonsillitis. The data illustrate the presence of polymicrobial flora in the cores of normal noninflamed tonsils and the increase in their number and encapsulation during the inflammatory process.
