Anaplasma platys -Like Infection in Goats, Beijing, China.

As one of the important tick-borne zoonotic pathogens,Anaplasmahas both veterinary and public health significance. Here, we performed a survey ofAnaplasmainfection in the goats from a farm in Beijing, China, and found 44.6% (41/92) were infected withAnaplasma capra, and 22.8% (21/92) were infected withAnaplasmasp. ThisAnaplasmasp. bacterium was close to a recently emergingAnaplasma platysstrain based ongltAandgroELgene phylogenetic analysis. As to further understand the characteristics ofAnaplasmasp., we raised a couple of positive goats (n = 2) in the laboratory with tick-free settings. We observed inappetence, vomiting, high fever, and weakness of limbs in the goat's offspring (n = 3). In addition, the blood samples from all offspring were all positive of thisAnaplasmaspp. We did not see any intracellular morulae in neutrophils, monocytes, and erythrocytes, but we identified some in the platelets of the blood smears from the positive goats by light microscopy. We named itA. platys-like and suggested it may infect platelets and be transmitted vertically through the placenta of goats. These findings deserve further evaluation.
