Anaplasma capra, an emerged tick?borne agent, maintained its natural cycles via ticks and host reserviors. To survey for A. capra infection in Haemaphysalis longicornis in North China, a total of 311 H. longicornis ( 95 adults, 156 nymphs, 60 larvae) were collected in Beijing during May to Sept. in 2012 and 2015. A. capra was identified from 3 adults (3?2%) when amplified by PCR targeting gltA gene and rrs (16S rRNA). No infection was found in the nymphs and larvae. Phylogenetic analyses revealed that the partial gltA and 16S rRNA sequences obtained in the ticks are identical to A. capra harvseted from Mudanjiang′s patients in 2014. The finding of A. capra in ticks in North China indicates the natural foci may exist in North China and it is urgent and necessary to prevent and control the emerged tick borne disease in this area.
