Anaplasma species are obligate intracellular pathogens that threaten the health of both humans and animals worldwide. This study aimed to determine the prevalence of Anaplasma species in stray dogs in Anhui Province, China. Blood samples from 201 apparently healthy stray dogs were collected from August 2017 to January 2018, and Anaplasma spp. infection in these dogs was evaluated by nested PCR and phylogenetic analysis. The overall infection rate of Anaplasma spp. in stray dogs was 38.3% (77/201). The prevalences of single infection of A. platys, A. phagocytophilum and A. ovis were 15.4%, 11.9%, and 8.5%, respectively. Co-infection rate of A. platys and A. phagocytophilum was 1.5% and that of A. platys and A. ovis was 0.5%. Co-infection by these three pathogens was found in one sample (0.5%). This is the first report of Anaplasma spp. infections in stray dogs from Anhui, China.
无形体属物种是专性细胞内病原体，威胁着全球人类和动物的健康。本研究旨在确定中国安徽省流浪犬中无形体属物种的流行情况。2017 年 8 月至 2018 年 1 月期间，采集了 201 只明显健康的流浪犬的血液样本，通过巢式 PCR 和系统进化分析评估这些犬只的无形体属感染情况。流浪犬无形体属总感染率为 38.3%（77/201）。单一感染的无形体属 A. platys、A. phagocytophilum 和 A. ovis 的流行率分别为 15.4%、11.9%和 8.5%。A. platys 和 A. phagocytophilum 的合并感染率为 1.5%，A. platys 和 A. ovis 的合并感染率为 0.5%。在一个样本（0.5%）中发现了这三种病原体的合并感染。这是中国安徽流浪犬无形体属感染的首次报告。
