Midpoint rooted Bayesian phylograms of Anaplasma sp. 23S-5S rRNA sequences from ticks, vertebrate hosts, and clinical patients. The tree was constructed using MrBayes (http://mrbayes.csit.fsu.edu/). Numbers at the nodes correspond to the posterior probabilities following 1,000,000 iterations. The 23S-5S rRNA sequences from this study are labeled with the study site name and Ixpac (Ixodes pacificus). The GenBank accession numbers for representative Anaplasma sp. sequences are as follows: Lizard 1 (JF487930), Lizard 2 (JF487929), gray squirrel (JF451142), and dusky-footed woodrat (JF451141) were described previously from northern California.21 MRK, horse origin (JF451139); HZ, human isolate (JF451140); Anaplasma marginale (AY048815); Anaplasma central (NR_076686); and Ehrlichia chaffeensis (NR_076400) are all clinical isolates from North America.
