目的了解安徽省农村地区人群和家畜蜱源立克次体病感染状况和分布特点,为科学防治蜱源立克次体病提供依据。方法 2009年4～5月在安徽省广德县、明光市和怀远县采集农村人群血清613份,家畜血清150份,使用试剂盒,采用间接免疫荧光法(IFA)检测斑点热(SGF)、人单核细胞埃立克体病(HME)和人粒细胞无形体病(HGA)抗体,并进行不同地区、年龄、性别比较。结果 613份人血清中,SGF阳性血清250份,阳性率40.78%;HME阳性血清98份,阳性率15.99%;HGA阳性血清17份,阳性率2.77%。SGF血清抗体存在年龄、性别和地区差异,HME血清抗体存在地区差异;150份家畜血清中,SGF阳性血清91份,阳性率60.67%,HME阳性血清33份,阳性率22%;HGA阳性血清4份,阳性率2.67%;家狗血清HGA阳性率显著高于羊和牛,家畜SGF和HME血清抗体存在地区差异。结论安徽省农村地区存在蜱源立克次体病自然疫源地。
Objective To understand the status and distribution of rickettsial disease in populations and livestock in rural areas of Anhui Province and provide evidence for the scientific prevention and treatment of rickettsial rickettsial disease. Methods From April to May 2009, 613 serum samples from rural areas and 150 serum from domestic animals were collected in Guangde County, Mingguang City and Huaiyuan County of Anhui Province from April to May in 2009, and indirect immunofluorescence (IFA) Human monocytic Ehrlichosis (HME) and human granulocytic anaplasmosis (HGA) antibodies, and compared by region, age and gender. Results Among 613 human serum samples, 250 were positive for SGF-positive sera and 40.78% for positive sera. HME-positive sera were 98 and the positive rate was 15.99%. HGA-positive sera were 17 and the positive rate was 2.77%. There were regional differences in serum antibody to SGF in serum and HME serum antibody. There were 91 serum SGF-positive sera among 150 serum samples, with a positive rate of 60.67% and 33 positive HME sera with a positive rate of 22% , The positive rate was 2.67%. The positive rate of HGA in domestic dogs was significantly higher than that in sheep and cattle. There were regional differences in serum antibodies to SGF and HME in domestic animals. Conclusion The natural source of tick-derived rickettsial disease exists in rural areas of Anhui Province.
