摘　　要：目的:构建临床梅毒螺旋体菌株梅毒兔感染模型。方法:收集梅毒患者梅毒螺旋体菌株,制备菌悬液,将悬液注入新西兰兔睾丸并连续分离传代,观察新西兰雄兔临床症状及血清学变化情况。结果:共收集临床梅毒螺旋体菌6株(A-F),接种成功5株—A、C、D、E、F菌株,分别于接种后第28天、7天、14天、32天、35天检测到TPPA转阳。将获得的临床菌株A继续传代,接种6天开始睾丸出现肿胀,平均7.7天TPPA转阳。结论:通过兔睾丸接种的方法,可以成功分离传代临床梅毒螺旋体菌株。Objective: To establish the animal model of Treponema pallidum strain clinically collected. Methods: The clinically isolated Treponema pallidum strain was prepared for suspension. The suspension was injected into New Zealand rabbit and continuously passaged to next generations. The clinical symptoms of rabbit and serological changes were observed and tested. Results: A total of 6 strains of Treponema pallidum (A-F) were collected and 5 strains (A, C, D, E, F) were successfully inoculated. TPPA conversion was detected on days 28, 7, 14, 32 and 35, respectively. The strain A was passaged and the testicles showed swelling after inoculated strain A for 6 days and positive TPPA conversion after 7.7 days on average. Conclusion: The strain of Treponema pallidum can be successfully isolated clinically and passaged by rabbit testicular inoculation method.
