This investigation is based upon the occurrence of oral protozoans among 25 periodontalclasial patients in Stockton, California. It is concerned, in part, with the correlation of infections with age, sex and oral health of the host and, in part, with culture techniques. The specific cultivation of Trichomonas tenax was explored in an effort to employ an improved experimental medium.
Trichomonas tenax and Endamoeba gingivalis are the only protozoans known to occur commonly in the human mouth. Distribution is cosmopolitan and there are no known endemic areas. Incidence of these two protozoans, among periodontalclasial patients, has not been reported since the study made by Jirovec, Bertos, Mezl, and Novack (1942).
