结果：1、通过不同感染途径的实验证实，滴鼻感染的小鼠主要表现为间质性肺炎，而腹腔注射感染小鼠则以脾脏、肝脏肉芽肿为主要病变。2、通过不同剂量的感染实验发现，随着感染Q热立克次体剂量的加大，动物病变愈加严重。3、通过感染后不同时间的动态病理学观察发现，在腹腔注射后第2d的脾和肝脏即可发现病原体，主要脏器的病理变化从第2d到第12d逐渐加重，第7d动物的病变最典型，至感染后14d动物的受损器官已开始出现修复性变化。4、 Q热立克次体主要侵害机体的网状内皮系统，在感染小鼠的肝、脾、肺和外周血管单核巨噬细胞以及血管内皮细胞胞浆中查见病原体。5、透射电镜观察可见Q热立克次体主要位于巨噬细胞吞噬溶酶体内，呈多形性，多见圆形和杆状，大小不一。
