The primary infection by Pneumocystis of normal, healthy infants is asymptomatic and goes undiagnosed. Microscopy diagnosis of Pneumocystis was sought in lung impression smears (LIS) from two ~3-month-old infants dying unexpectedly in the community. Pneumocystis nuclei and cysts were identified using Hema-Gurr with subsequent Gomori–Grocott staining in the same spot documenting that these stains may be complementary. LIS provide for an observer–dependent, inexpensive, and ready-available method for detection of Pneumocystis in infant lungs.
