Phylogenetic tree based on Anaplasma phagocytophilum 16S rRNA partial sequences (546/565 bp) obtained in this study. The tree was constructed with the neighbor-joining method using MEGA7.0. Numbers at nodes represent percentage occurrence of clades in 500 bootstrap replications of data. Sequences from this study are shown in bold. Anaplasma bovis (AB588968) was used as the outgroup. The black circles indicate the sequences from Tibetan sheep in this study. For abbreviations, see Figs. 1 and 2
