Divergence of p33/34 gene of Theileria found in Cervus nippon in Japan.
The 18S rRNA gene and the piroplasm major immunodominant protein gene (p33/34) of Theileria from various subspecies of sika deer in 8 different locations of Japan were analyzed. The similarity between 633 bp partial sequences of the 18S rRNA gene among various subspecies of sika deer was found to be between 99.7% and 100%. While the percent identities of the 412 bp partial p33/34 gene sequence and deduced amino acid sequences between Theileria of sika deer from Yamaguchi Prefecture and those found in deer from other Prefectures, were comparatively low, 68.7% to 70.1% and 64.1% to 70.0% respectively. These findings suggest that there are at least two genetically distinct strains of Theileria of sika deer in Japan.
