Ectoparasite-free, SPF Italian Wistar rats were consistently found to carry a latent infection with Haemobartonella muris, activable by splenectomy. In an inbred line this diminished and eventually ceased in six generations. Experimental infection from wild rats demonstrated that this was not apparently due to immunity.
无体外寄生虫的SPF级意大利威斯塔大鼠一直被发现携带鼠血巴尔通体的潜伏感染,脾切除可激活这种感染。在一个近交系中,这种感染在六代中逐渐减少并最终停止。来自野生大鼠的实验性感染表明,这显然不是由于免疫所致。
