Phylogenetic tree showing major piroplasm surface unit gene sequences for Theileria species. The tree uses reference sequences from the major genotypes for T. orientalis (4). Sequences from infected cattle in Virginia, USA, cluster with genotype 2 sequences. Numbers along branches are bootstrap values. Scale bar indicates nucleotide substitutions per site.
