目的 :对云南北部金沙江流域恙虫病立克次体流行株鼠免疫血清及病人血清进行分型。方法 :免疫荧光法。结果 :2 1个分离株中 12株为Karp型 (占5 7.14% ) ,6株为Gilliam型 (占 2 8.5 7% ) ,3株分型阴性 ;16 7份阳性血清中有 10 8份为Karp型 (占 6 4.6 7% ) ,37份为Gilliam型 (占 2 2 .16 % ) ,18份为Karp +Gilliam两型混合感染(占 10 .78% ) ,3份为Kato型、1份为Karp +Kato两型混合感染。 结论 :从媒介、宿主和病人三方面证实该地存在广泛的恙虫病自然疫源地 ;同时查明当地恙虫病立克次体流行型别以Karp型为主 ,次为Gilliam型 ,并有少量Kato型存在
Objective: To classify the serum of immunized rabies and rickettsia serogroup Rickettsia tsutsugamushi of Jinshajiang River in northern Yunnan. Methods: Immunofluorescence method. RESULTS: Twelve of the 2 isolates were Karp-type (5 7.14%), 6 were Gilliam-type (2 8.57%) and 3 were negative; 10 of 16 positive sera were Karp type (6 4.6 7%), 37 Gilliam type (21.2%), 18 Karp + Gilliam mixed infection (10.78%), 3 Kato type and 1 Karp + Kato two types of mixed infection. Conclusion: There is a wide range of natural epidemic foci of tsutsugamushi disease in the area from media, host and patient. At the same time, it is found that the prevalence of Rickettsia tsutsugamushi is Karp-type and Gilliam-type, with a small amount Kato type exists
