Phylogenetic analyses of partial 16S rRNA genes of Anaplasma phagocytophilum identified in domestic animals from surveyed areas in China (A, rectangular tree; and B, radiation tree). Blue indicates sequences determined from animals in the study, red indicates sequences obtained from patients from Anhui Province in 2006 and Shandong Province in 2007, purple indicates sequences obtained from ticks from Shandong Province in 2007. Green is A. phagocytophilum strain Slovenia, orange is A. phagocytophilum strain HZ, and sky blue is A. phagocytophilum strain Webster.
