RMKTWT9N–A photomicrograph depicting the histopathology associated with pulmonary actinomycosis. A suppurative disease caused by Gram-positive endogenous oral bacteria of the family Actinomycetaceae . Note the fibrotic, thick-walled abscess formation, and presence of granulation tissue indicative of a chronic inflammatory process. Image courtesy CDC/Dr. Martin Hicklin, 1964.

Trevisan regarded it as the type species of the new genus. N. actinomyces Trevisan (Syn. Actinomijces hovis Harz) was given as the second species. This was followed by A^. foersteri (Cohn) Trevisan (Syn. Streptothrix foersteri Cohn). In con- sidering these facts. Breed and Conn con- cluded that "There appears to be no justifi- cation for the use of the term Nocardia Trevisan for the entire group of organisms included in the Actinomycetaceae

Kluyver and van Xiel suggested the removal of the family Mycobacteriaceae from the Actinomycetales altogether. Langeron suggested the following system of classification of actinomycetes: I. Euactinomyces, aerobes. II. Cohnistreptothrix, anaerobes, grow poorly on artificial media.. Please note that these image

Zu diesen gehört neben vielen harmlosen Formen auch der ge- fürchtete Erreger der Strahlenpilzerkrankung, ferner die teilweise sehr gemeinen Angehörigen der Gattung Streptothrix, die im Erdboden z. B. in der Nähe von Wurzeln höherer Pflanzen häufig vorkommen, teilweise. >-J- ^ Abb. 62
