摘　　要：通过对云南省云龙县恙虫病立克次体分离株对实验动物的致病性研究表明，各分离株对小白鼠和豚鼠均有较强的致病性，对家兔亦有一定的致病性，而恒河猴则不敏感；经毒力测定，７个分离株中，有５株ＬＤ５０≥８．５，为强毒株。该县恙虫病立克次体分离株抗原型以Ｇｉｌｉａｍ型为主，其次为Ｋａｒｐ型，不同的抗原型株间有很强的交互保护力。This paper reported the results of biological characteristics of Rickettsia tustusgamushi from Yunlong County, animal experiment showed that all strains had a strong virulence to mice and rabbits,all strains also had virulence to the guinea pig, but Macaca mullata were not sensitive to it. The virulent test showed that there was not any relativity between serotypes and virulence.Strains of Rickettsia tustusgamushi have a stronger cross protective capacity between different types of Rickettsia tustusgamushi.
