Phylogeny analyses of T. gondii isolates using Splits Tree software. (A) The result of network completed with relatively conserved apicoplast genome DNA markers. (B) The network calculated by the normal mutation frequency of genomic multilocus. (C) The Neighbor-Net analysis conducted with the rapidly evolving marker W35. Phylogenetic analyses revealed that W35 marker has highly divergent properties and Chinese isolates possess highly clonal characteristic. *, no accession number from ToxoDB.
