Phylogenetic analysis of A. ovis strains based on the protein sequences of MSP4 gene was inferred using the neighbor-joining method. The optimal tree with a branch length sum of 0.22235680 is shown. The percentage of replicate trees in which the associated taxa clustered together in the bootstrap test (1,000 replicates) is shown next to the branches. The evolutionary distances were computed using the Poisson correction method. All positions containing gaps and missing data were eliminated. Sequences newly obtained in the present study are indicated in boldface.
