Human granulocytic anaplasmosis (HGA) is an emerging tick-borne infectious disease. To determine the prevalence of HGA in central and southeastern China, a total of 323 human sera were collected from individuals at high risk for exposure to ticks and animals. The IgG antibody against the etiologic agent of HGA, Anaplasma phagocytophilum was detected with indirect immunofluorescence assay. The results showed that 20% of the tested individuals (64/323) were positive to A. phagocytophilum and that the incidence was higher in male (22%) than female (16%). We concluded that A. phagocytophilum infection was prevalent in central and southeastern China.
人粒细胞无形体病（HGA）是一种新出现的蜱传传染病。为确定中国中部和东南部地区HGA的流行情况，共采集了323份来自有蜱虫和动物接触高风险个体的人血清。采用间接免疫荧光法检测针对HGA病原体嗜吞噬细胞无形体的IgG抗体。结果显示，20%（64/323）的受测个体对嗜吞噬细胞无形体呈阳性反应，男性发病率（22%）高于女性（16%）。我们得出结论，嗜吞噬细胞无形体感染在中国中部和东南部地区较为普遍。
