Abstract

Anaplasma phagocytophilum is an Ixodes species tick-transmitted bacterium that is capable of infecting a variety of host species, although there is a diversity of bacterial strains with differing host tropism. Recent analysis of A. phagocytophilum strains suggested that "drhm", a gene locus designated "distantly related to human marker" (drhm), which was predicted to be an integral membrane protein with possible transporter functions was not present in available canine and human isolates. By assessing 117 strains from 14 host species from across the US, we extended this analysis. Phylogenetic clades were associated with geography, but not host species. Additionally, a virulent clade that lacks drhm and infects dogs, horses, and humans in northeastern US was identified.
