目的了解北京东北部山区人群嗜吞噬细胞无形体的感染状况,为制定相应的防控策略提供依据。方法在北京密云与怀柔区采集人群血清,采用间接免疫荧光法检测嗜吞噬细胞无形体IgG抗体,进行血清流行病学调查。结果 801份血清中嗜吞噬细胞无形体IgG抗体阳性者106份,阳性率13.23%,其中密云区为13.48%,怀柔区为12.70%,差异无统计学意义(P>0.05)。结论北京密云与怀柔区正常人群中均有嗜吞噬细胞无形体感染的存在,应加强人粒细胞无形体病的监测和防控工作。 Objective To understand the infection status of phagocytic phagocytes in mountainous area of ​​northeastern Beijing and to provide evidence for the development of appropriate strategies for prevention and control. Methods Human serum was collected from Miyun and Huairou districts of Beijing. The serum immunoglobulin was detected by indirect immunofluorescence and serological tests were performed. Results There were 106 positive phagocytosis phagocytosis IgG antibodies in 801 serum samples, the positive rate was 13.23%. Miyun area was 13.48% and Huairou area was 12.70%. There was no significant difference (P> 0.05). Conclusions The presence of phage phagocytosis in normal population of Miyun and Huairou District in Beijing should be strengthened and the prevention and control of human granulocyte apomorphosis should be strengthened.
