Using immunoblots to analyze antigenic relationships among the pathogenic spotted fever and typhus group rickettsiae, I found that the rickettsial lipopolysaccharide (LPS) was a group-specific antigen. All the rickettsiae examined had 135-kDa and 58-kDa protein antigens. The spotted fever rickettsiae and Rickettsia canada had, in addition, 190-kDa protein antigens which were antigenic analogs of previously described protective antigens of R. conorii and R. rickettsii.
通过免疫印迹法分析致病性斑点热群和斑疹伤寒群立克次体之间的抗原关系，我发现立克次体脂多糖（LPS）是一种群特异性抗原。所有检测的立克次体都有135 kDa和58 kDa的蛋白质抗原。此外，斑点热立克次体和加拿大立克次体有190 kDa的蛋白质抗原，它们是先前描述的康氏立克次体和立氏立克次体保护性抗原的抗原类似物。
