From: Discovery of a new Theileria sp. closely related to Theileria annulata in cattle from Sri Lanka
18S rRNA phylogeny. A maximum-likelihood phylogenetic tree was constructed using nine long 18S rRNA gene sequences (1,536 bp) from Sri Lanka and the T. annulata and T. lestoquardi sequences from GenBank. P and N series numbers provided with the Sri Lankan sequences indicate animal IDs from Polonnaruwa and Nuwara Eliya, respectively. The Sri Lankan sequences clustered together and formed a sister clade to the common ancestor of the T. lestoquardi and T. annulata sequences from other countries. Note that the bootstrap support for T. annulata, T. lestoquardi, and Sri Lankan clades and their separation improved compared with that in phylogeny constructed with short 18S rRNA sequences.
