Abstract
Abstract 1.1. It is possible now to determine quantitatively the degree of urinary trichomoniasis by the use of the hemocytometer. The flagellates are counted as are cells in spinal fluid and the number per cubic millimeter of the sample examined is thus obtained. When the protozoan is too motile for accurate enumeration, two drops either of 0.25 per cent formalin or of 1 per cent formalin are added to 5 c.c. of the material. Centrifugalization without apparent injury to the trichomonads is possible, especially if formalin is used as indicated prior to this procedure. 2.2. The application of this method in vaginal trichomoniasis, as well as a modification of it outlined in the text for the numerical determination of these organisms in prostatic secretion, has been suggested. 3.3. The clinical significance of this procedure rests in the ability to estimate quantitatively the extent of infestation, its progression or decline, and the efficacy of therapy. 4.4. There is nothing in the morphologic and biologic characteristics of other flagellates, amebae and ciliates, if and when so encountered, that would prevent a satisfactory application of this method. 5.5. The great dilution of formalin which appears to be toxic to trichomonads suggests its possible use in therapy, both in the urinary and digestive tracts.
