NTPDase activity among fresh Trichomonas vaginalis isolates (nos. 1-5 (A) and 7-10 (B) and a representative long-term-grown (no. 6) isolate. Isolate 347 V+ (no. 6a) and 347 V- (no. 6b) refer to presence or absence of dsRNA virus, respectively, as described in the Materials and Methods section. The enzyme activities are those using ATP (clear bars) and ADP (hatched bars) as substrates. Isolates (B) were separated from (A) because of the ATP:ADP hydrolysis ratio of ∼2 : 1, that is distinct from that of NTPDase1 (isolates nos. 1-5). Data are expressed as the mean±S.D. for at least 3 experiments.
