Representative experiments on the effect of growth of trichomonads in low- (centre, hatched bars) versus high-iron (solid black bars) medium on NTPDase activity among 2 virus-minus (T016 and UT99-1) and 2 virus-harbouring (UT99-6 and T068-II) fresh Trichomonas vaginalis isolates. Different iron conditions were compared with normal TYM-serum medium. Bars represent the mean±S.D. for at least 3 experiments. Results were analysed statistically by the Student’s t-test (P<0·05). Statistically significant enzyme activity differences when compared to control are indicated by an asterisk.
