Transovarian passage of salmonella was evaluated in snakes by cesarean delivery and subsequent bacteriological examination of fetuses. In all cases, the same Salmonella serotype was isolated from the feces of gravid females and their fetuses. The visceral distribution of salmonella in normal snakes was found to involve almost all visceral organs. Of nonenteric organs examined, salmonella was recovered most often from the livers and ureters. Experimental infections with Salmonella typhimurium and Salmonella arizonae were established by oral, intracardial, and intracoelomic routes. Animals infected orally shed the organism in feces, but did not develop humoral antibodies or any detectable adverse effect. Animals injected by the intracardiac and intracoelomic routes developed antibody titers of 1:256 to the respective salmonella serotypes, but remained normal throughout the experiment. On the basis of results, salmonella was regarded as an opportunistic organism in reptiles.
通过剖腹产及随后对胎儿进行细菌学检查，评估了沙门氏菌在蛇类中的经卵巢传播情况。在所有案例中，从怀孕雌蛇及其胎儿的粪便中分离出了相同的沙门氏菌血清型。研究发现，正常蛇体内沙门氏菌的内脏分布几乎涉及所有内脏器官。在所检查的非肠道器官中，沙门氏菌最常从肝脏和输尿管中检出。通过口服、心内注射和体腔注射途径建立了鼠伤寒沙门氏菌和亚利桑那沙门氏菌的实验性感染。经口服感染的动物粪便中排出该病菌，但未产生体液抗体，也未出现任何可检测到的不良反应。经心内注射和体腔注射途径感染的动物针对相应的沙门氏菌血清型产生了1:256的抗体效价，但在整个实验过程中保持正常。根据这些结果，沙门氏菌被视为爬行动物中的一种机会性致病菌。
