Plasmid copy numbers were quantitated before (day 0) and after (day 28) removal of pyrimethamine drug pressure in transgenic parasites with PvCEN11S2-H86HD-TG (PvCEN11S2), PvCEN11S3-H86HD-TG (PvCEN11S3), PyCEN5-H86HD-TG (PyCEN5), or pNoCEN. Three or five mice were used for each group on days 0 and 28, respectively. After the one-way ANOVA test indicated significant difference, Tukey's post-hoc multiple comparisons test was performed. Significant difference was indicated with p values. n.s. indicates not significant (p ≥ 0.05).</p
