FIG. 2.

Effect of mannose on CPE mediated by A. castellanii trophozoites. CHCE cell monolayers were incubated for 48 h with trophozoites in MEM with (▨) or without (□) 100 mM mannose (A) or with 100 mM lactose (▧) (B). Monolayers were washed and stained with Giemsa stain, and CPE was assessed spectrophotometrically.
