梅毒螺旋体选择性地用特定的宿主成份包被自己的能力可能代表着一种重要的生存本性,它标志着梅毒螺旋体的毒力。例如,螺旋体的重要免疫原的掩盖就似乎是毒性螺旋体的一种重要特性,否则,宿主的免疫监视功能就将以这些免疫原作靶子而将螺旋体制动并中和。在其它一些专为检验特异性宿主血浆蛋白与螺旋体表面相结合的关系而设 The ability of Treponema pallidum to selectively coat its own abilities with specific host components may represent an important viability that marks the virulence of Treponema pallidum. For example, the masking of the important immunogen of spirochetes appears to be an important characteristic of the virulent spirochetes, otherwise the host’s immune surveillance function will brakes and neutralizes the spirochetes with these immunogens as targets. In other experiments designed to test the relationship between a specific host plasma protein and the spirochete surface
