本文对莱姆病病原体伯氏疏螺旋体(Borrelia burgdorferi)减毒分离株的免疫原性和保护效果进行了评价。菌株HB 19的分离株的同基因对在鞭毛的表达上不同;既不产生全身感染,也不持续存在于小鼠的皮肤中。在比较皮内给药的活鞭毛轴承和无鞭毛的细胞,无鞭毛的分离等于或上级的鞭毛轴承野生型在引发生长抑制抗体和预防感染的小鼠。在活的和杀死的无鞭毛细胞的比较中,对活细胞的免疫应答上级对杀死的细胞的免疫应答,如通过ELISA、生长抑制测定和感染性攻击所评估的。对活细胞和死细胞的50%保护剂量分别为1038和105.2(P<0.05)。
The immunogenicity and protective efficacy of an attenuated isolate ofBorrelia burgdorferi, the agent of Lyme disease, were evaluated. An isogenic pair of isolates of strain HB19 differed in the expression of flagella; neither produced systemic infection or persisted in the skin of mice. In a comparison of intradermally administered live flagella-bearing and flagella-less cells, the flagellaless isolate was equal to or superior to the flagella-bearing wild type in eliciting growth-inhibiting antibodies and preventing infection in mice. In a comparison of live and killed flagella-less cells, immune responses to live cells were superior to those to killed cells, as assessed by ELISA, growth inhibition assay, and infectious challenge. The dose protecting 50% of mice was 1038and 105.2for live and killed cells, respectively (P< .05).
