Trichomonas vaginalis induces apoptosis of human neutrophils. (a and b) Cytospin preparations of neutrophils were stained with Giemsa, and apoptotic cells (arrow) were seen morphologically (×400); (c and d) Transmission electron micrographs of neutrophils. The micrographs show neutrophils treated as follows: (a) neutrophils cultured with medium only for 12 h, (b) neutrophils co-cultured with live Trichomonas vaginalis (T) for 12 h, (c) freshly isolated normal neutrophils, (d) neutrophils and T. vaginalis were co-incubated for 12 h at 37°C. Several activated neutrophils surrounded one trichomonad (T). Two neutrophils show typical features of apoptosis (chromatin condensation).
