In this study, we examined A. Because birds may be carriers of zoonotic pathogens, infection of humans with these pathogens may occur.

Genetic characterization of Anaplasma ovis strains from bighorn sheep in Montana. Human granulocytic anaplasmosis and Anaplasma phagocytophilum.

The structure of Msp1a tandem repeat and the amino acid sequences vary among strains, which has also been shown for A.
