Fig 5. Median-Joining network of 9 and 15 haplotypes observed in T. parva population in South Sudan based on the polymorphic sites of (A) Tp1 and (B) Tp2 genes, respectively.

The sizes of the circles are proportional to the haplotype frequencies. The origin of each haplotype is colour coded as follows: Bor = Yellow; Juba = Red; Yei = Blue; Kajo keji = Green; Median vector = Brown; T. parva Muguga = Black. The numbers in red in (A) represent the mutations that differentiate the haplotypes.
