[The incidence of Actinomyces israeli colonization in tonsillar tissue. A histopathological study]

The presence of the Actinomyces usually is not determined by the common histologic examination of preparations of tonsillar tissue which has been removed surgically. The Actinomyces are common saprophytic microorganisms which are found inter alia in the oral cavity and palatine tonsils. In this study, the authors examined histologically 238 surgical preparations of tonsillar tissue. In 84 of these, that is 35.21%, it has been noted, except the others, the presence of Actinomyces israeli. At the same time, the authors state their views concerning the contribution of the Actinomyces of tonsillar crypts to the pathogenesis of chronic tonsillitis.
