Abstract
Three cultures of Actinomyces have been identified as Actinomyces propionicus. Two of these strains are recent isolates, one, 427, from a case of cervico-facial actinomycosis, and one, 439, from a case of lacrimal canaliculitis. The third strain, 346, was described by F. Lentze as A. israelii serological type II. These three strains were compared with the type strain of A. propionicus ATTC 14157 and with known strains of five other Actinomyces species. Morphologically and biochemically the three new cultures of A. propionicus were identical with the type strain but closely resembled A. israelii. In serological tests making use of fluorescent antibody, all four A. propionicus strains gave negative results with antisera for A. israelii, A. bovis, A. naeslundii, and A. eriksonii, but gave positive results with antisera for A. propionicus 14157 and strain 346. The A. propionicus antisera did not stain other Actinomyces species. A. propionicus contains diaminopimelic acid (DAP) in its cell wall and produces propionic acid from glucose. All three new isolates were shown to contain DAP and to produce propionic acid. By use of the presence of DAP in the cell wall and serological tests as the differential criteria, the three cultures described in the report were specifically identified as A. propionicus.
