Neighbour-joining tree showing relationships among 79 cattle and buffalo-derived <i>T. parva</i> isolates.

These data are based on the sequences of 35 Tp1 gene alleles obtained in this study. T. annulata (TA17450 Strain_Ank) was used as an outgroup to root the tree. Isolates with their corresponding alleles in parentheses are indicated and colour-coded based on their geographical location in Kenya. Isolates from outside Kenya (Tanzania, Uganda, Zambia and Zimbabwe) are depicted in black. The TP03_0849 gene from the T. parva (Muguga) genome sequence was also included in the analysis. Bootstrap values >50% are shown above branches. A Major clade and minor clade with two sub-clusters is indicated.
