The clinical similarity of mytotic infection of the lung to tuberculosis renders the differential diagnosis of both therapeutic and prognostic importance. Since but relatively few cases of infection by streptothrix, as distinguished from actinomycosis, have been recognized and reported, the following record of a case seems pertinent.
REVIEW OF THE LITERATURE
Cohn1 in 1875 first gave the name Streptothrix foersteri to a filamentous branched organism isolated from a lacrimal duct concretion.1a Eppinger,2 however, gave the first classic description of a case—an abscess of the brain from which a pure culture could be isolated using the ordinary mediums. He named this fungus Cladothrix asteroides. Further work confused this organism with the organism now known, at least generically, as Actinomyces (Bollinger3), which is especially characterized by the sulphur granules, clubbed ends of the filamentous mycelium and the fact that it is most commonly seen in the "lumpy jaw" infections of cattle.In
