Hypertrophy of acridine orange granules in Toxoplasma gondii.
The hypertrophy of acridine orange (AO) granules is found in the cytoplasm of living tachyzoites of Toxoplasma gondii stained with AO under special conditions and observed by means of the fluorescent microscope. Large acid phosphate (Ac Pase) granules appear in the cytoplasm when the above-mentioned tachyzoites are treated more by Gomori's method for Ac Pase. It was confirmed in this investigation that the hypertrophied AO granules are identical to the hypertrophied Ac Pase one by following both granules in the same single tachyzoite throughout the test.
