title: Further studies on the interaction of Toxoplasma gondii with neutrophils and eosinophils.
abstract: Tachyzoites of Toxoplasma gondii are ingested by neutrophils and eosinophils through a process which can be significantly inhibited by previous incubation of the host cells with cytochalasin D. Although dividing zoites within the leukocytes could be observed, after 3 h of infection, killing of parasites within the parasitophorous vacuole was detected. Cytochemical studies showed that both in neutrophils and eosinophils there is a process of NADP(H) oxidase activation, which was higher in the latter.
