  1. (A) Candidate genes that have non-conservative, nonsynonymous amino acid changes between RH-ERP and GT1 and are expressed highly in RH-ERP as determined by Toxoplasma arrays. Toxoplasma array expression values are log2 transformed values, ranging from 6.5 (minimum) to 14.3 (maximum). (B) Candidate genes that are differentially expressed between intracellular and extracellular RH-ERP tachyzoites [44]. (C) Candidate genes that are differentially expressed between M4 in vitro tachyzoites, in vitro induced bradyzoites and in vivo cysts [46].
