The tree was constructed using the neighbour-joining method [34]. The percentage of replicate trees in which the associated taxa clustered together in the bootstrap test (1100 replicates) is shown next to the branches [16]. The evolutionary distances were computed using the Tamura-Nei method [38] and are in the units of the number of base differences per site. Evolutionary analyses were conducted in MEGA5.1 [39]. GenBank accession numbers are given in parentheses. Species described in this study are indicated with a black square. (A) Partial sequence 18S ssu rRNA gene phylogenetic tree of the species identified in this survey and the main small ruminants’ Theileria species. (B) Partial sequence 18S ssu rRNA gene phylogenetic tree of the species identified in this survey and the main small ruminants’ Babesia species.
