In this work, we describe the ability of living trophozoites of Giardia lamblia to hydrolyze extracellular ATP. In the absence of any divalent cations, a low level of ATP hydrolysis was observed (0.78±0.08nmol Pi×h −1 ×10 −6 cells). The ATP hydrolysis was stimulated by MgCl 2 in a dose-dependent manner. Half maximum stimulation of ATP hydrolysis was obtained with 0.53±0.07mM...
