Studies on the Actinomycetes Isolated from the Actinomycosis of Human Jaws

Abstract

In these three years 48 strains of actinomycetes from the 49 actinomycotic lesions of the human jaw were isolated in the clinic of our university.
Depending on the Bergey's Manual (published in 1948) these strains were classified into the following groups.
Group A. Genus Actinomyces ………………………31 strains
Act. bovis Harz 8……………… strains
Act. israeli (Kruse) 23……………… strains
Group B. Actinomyces-like organisms 13………………strains
a. aerobic types, but not Nocardia 5………………… strains
b. anaerobic 3………………strains
c. gas production in glucose broth, anaerobic………………5 strains
Group C. Corynebacterium 4………………strains
a. aerobic 2………………strains
b. anaerobic 2………………strains
It seems to be interesting that actinomycosis can be caused by such strains in Group B and C. At present, from the clinical viewpoint, there is no difference in their symptome between the cases caused by organisms of belonging to the Group A, B and C, but gene-rally, except one case, there is not recognizable so-called “sulphur granules” in pus from cases caused by strains of Group B-c and Group C.
