Anaplasma phagocytophilum DNA was detected from a dog with canine granulocytic anaplasmosis (CGA) in Japan. Phylogenetic analysis of the DNA using 16s rRNA, gltA, and groEL sequences revealed that the strain was nearly identical to A. phagocytophilum detected from Apodemus agrarius (black-striped field mouse) in China and Korea. This report is the first phylogenetic study on A. phagocytophilum from a CGA case in Japan.
