Tick-borne fever predisposes sheep to secondary infections by Pasteurella haemolytica. Polymorphonuclear (PMN) cells obtained from sheep 2 to 7 days after the onset of parasitaemia due to Cytoecetes phagocytophila, the causative agent of tick-borne fever, were significantly more susceptible in vitro to the cytotoxin of P. haemolytica than PMN obtained from age-matched control sheep.
蜱传热使绵羊易继发溶血巴斯德菌感染。从因蜱传热病原体嗜吞噬细胞胞内菌（Cytoecetes phagocytophila）导致的寄生虫血症发作后2至7天的绵羊获取的多形核（PMN）细胞，在体外比从年龄匹配的对照绵羊获取的PMN细胞对溶血巴斯德菌的细胞毒素更敏感。
