Abstract：Anaplasma are obligate intracellular aetiological prokaryotes of tick-borne disease called anaplasmosis in mammals. Wild mammals are the primary reservoirs of Anaplasma pathogens. To identify Anaplasma species circulating among rodents and livestock in southeastern China, we investigated rodents, cattle and goats in mountainous and hilly areas of Zhejiang from 2008 to 2011. The Anaplasma 16S rRNA genes were amplified by two nested PCRs from livers and spleens and blood. Then the PCR products were sequenced. Sequence alignments and phylogenetic analyses indicated that there were at least six Anaplasma species circulating among rodents and livestock in southeastern China, which including A. phagocytophilum, A. bovis, A. marginale, and A. platys. And the novel species A. capra recognized recently were confirmed in cattle and goats in Zhejiang. It is the first report that A. bovis infection exists in rodents. It is speculated that there are some variations and new species circulating in Zhejiang. It is not clear whether genetic diversity would lead to changes in morbidity, pathogenicity and clinical characteristics.
