Leptospires (Leptospira interrogans serovar pomona) grown in chemically defined medium were immunogenic when given intradermally in humans if the leptospires were killed with formalin but not if they were boiled. Boiled leptospires were immunogenic for rabbits and hamsters and protected hamsters from challenge infection. On the other hand, boiled leptospires of the biflexa complex, serovar patoc, did retain some immunogenicity in humans, but the antisera did not protect hamsters against challenge with serovar pomona.
在化学成分确定的培养基中培养的钩端螺旋体(问号钩端螺旋体波摩那群),如果用福尔马林杀死后皮内注射给人类,具有免疫原性,但煮沸后则不然。煮沸的钩端螺旋体对兔子和仓鼠具有免疫原性,并能保护仓鼠免受攻击感染。另一方面,双曲钩端螺旋体帕托型煮沸后的菌株在人类中确实保留了一些免疫原性,但抗血清不能保护仓鼠免受波摩那群的攻击。
