Babesia divergens in human in Gansu province, China

Figures & data

Figure 1. Phylogenetic tree of Babesia spp. sequences based on the 18S rRNA genes obtained in this study (bold triangles) and those previously registered in GenBank. The tree was constructed using the neighbour joining method of MEGA7, and values are given at the nodes. Numbers above the branch demonstrate bootstrap support from 1000 replications.
