title: Acridine orange staining of Pneumocystis carinii.
abstract: Acridine orange was used to stain smears of mouse lung which contained cyst and trophozoite forms of Pneumocystis carinii. Trophozoite forms stained yellow to orange; however, cyst forms did not stain. Acridine orange is a rapid and sensitive method for demonstrating trophozoites of P. carinii in mouse lung tissue.
