目的：调查西藏阿里地区人、畜间５种自然疫源性疾病的感染情况。方法：采用间接免疫荧光实验（ＩＦＡ）、间接血凝实验，检查人、畜血清抗体水平。结果：当地人群斑点热、斑疹伤寒、恙虫病、Ｑ热及野兔热的自然感染率，抗体检出率分别为５７．５％（２３９／４１６）、３２．７％（１３６／４１６）、９．４％（３９／４１６）、４９．５％（２０６／４１６）、１．２％（４／３４９）；羊血清抗体检出率分别为５２．２％（３０６／５８６）、３３．３％（１９５／５８６）、４２．２％（２４７／５８６）、４０．３％（２３６／５８６）、２１．２％（９０／４２５）。结论：该地区上述５种疾病血清抗体检出率远高于国内其他区的同类调查结果
Objective: To investigate the infection status of five natural foci between people and livestock in Ali area of Tibet. Methods: Indirect immunofluorescence test (IFA) and indirect hemagglutination test were used to examine the antibody levels of human and livestock serum. Results: The natural infection rate and antibody detection rate of spot fever, typhus, scrub typhus, Q fever and hare fever in local population were 57.5% (239/416) and 32.7% (136/416) respectively, 9.4% (39/416), 49.5% (206/416) and 1.2% (4/349), respectively. The detection rates of goat serum antibodies were 52.2% (306/586), 33 respectively. 3% (195/586), 42.2% (247/586), 40.3% (236/586), 21.2% (90/425). Conclusion: The detection rate of the serum antibodies of the above five diseases in this area is far higher than that of other surveyed areas
