Figure 4

Phylogenetic tree showing small subunit rDNA gene sequences for Theileria species. Representative samples from cattle in 6 herds in Virginia, USA, cluster with the reference sequences for the Ikeda genotype. The next most closely related branch is composed of T. orientalis Chitose genotype and then T. orientalis Buffeli genotype. The outgroup is composed of a single reference sequence each for T. parva and T. annulata. Small subunit rDNA sequences for I4 and Al1 were of low quality (6.4% and 3.9

Representative samples from cattle in 6 herds in Virginia, USA, cluster with the reference sequences for the Ikeda genotype. The next most closely related branch is composed of T. orientalis Chitose genotype and then T. orientalis Buffeli genotype. The outgroup is composed of a single reference sequence each for T. parva and T. annulata. Small subunit rDNA sequences for I4 and Al1 were of low quality (6.4% and 3.9%, respectively). Numbers along branches are bootstrap values. Scale bar indicates nucleotide substitutions per site.
