FIG 2.

Phylogeny of 18S rRNA. A maximum likelihood phylogeny was constructed using 18S rRNA sequences determined in the present study and those retrieved from GenBank. The gene sequences determined in the present study are indicated by boldface type. Note that the Babesia sp. Mymensingh sequence determined in the present study and that previously reported from Bangladesh clustered together and formed a sister clade to B. bigemina. Additionally, Babesia sp. Hue-1 occurred separately, forming a sister clade to the common ancestor of Babesia sp. Mymensingh and B. bigemina.
