Abstract

The ability of naturally infected and cured mice to resist reinfection with tick-transmitted Borrelia burgdorferi was tested over a 1-year period. All of the mice were resistant to reinfection when they were challenged at 1.5 months after cure. The majority of animals were resistant to reinfection for up to 10.5 months after cure, but this resistance was lost at 1 year after cure. Both protected and unprotected animals showed a diverse array of antibodies on Western immunoblots. Protection was not associated with the killing of spirochetes in ticks, and naturally infected mice produced no antibodies to outer surface protein A (OSP A). The titers to whole Borrelia sonicate and OSP C, however, remained high throughout the 1-year study period. The levels of borreliacidal antibodies were highest in the 1.5 month-after-cure group. Natural immunity to reinfection with B. burgdorferi is limited in time, is complex, and may involve both humoral and cellular components.

摘要

在1年的时间里,对自然感染并治愈的小鼠抵抗蜱传播的伯氏疏螺旋体再次感染的能力进行了测试。当所有小鼠在治愈后1.5个月受到攻击时,它们都对再次感染具有抵抗力。大多数动物在治愈后长达10.5个月对再次感染具有抵抗力,但这种抵抗力在治愈后1年丧失。在蛋白质免疫印迹法中,受保护和未受保护的动物均显示出多种抗体。保护作用与蜱中螺旋体的杀灭无关,并且自然感染的小鼠不会产生针对外表面蛋白A(OSP A)的抗体。然而,在整个1年的研究期间,针对全伯氏疏螺旋体超声裂解物和OSP C的滴度仍然很高。杀螺旋体抗体水平在治愈后1.5个月的组中最高。对伯氏疏螺旋体再次感染的天然免疫力在时间上是有限的,是复杂的,并且可能涉及体液和细胞成分。
