摘　　要：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 。Objective:To survey rickettsia tsutsugamushi in Jinshajiang riverbasin of Northern part of Yunnan.Methods:Micro-IF.Results:The results of serological typing of 21 epidemic strains of R.tustusgamushi showed that 12 strains (57.14%) were Karp type; 6 strains (28.57%) were Gilliam type; 3 strains were unknow type. The study showed that main epidemic type of R. tustusgamushi in the epidemic area were Karp type. The results of serological typing 167 patients showed that 108 cases (64.67%) were Karp type; 37 cases (22.16%) were Gilliam type; 18 cases (10.78%) belonged to Karp+Gilliam type; 3 cases were Kato type; 1 case was Karp+Kato type. Conclusion:This study confirmed that there were scrus typhus focus widely in Jinshajiang riverbasin of northern part of Yunnan. And it made clear the relation between the epidemic strains and standard strains in the area.
