Following attachment to the host immunized with purified antigens, midgut antigens, salivary gland antigens and reinfestation by I. sinensis, the midgut of tick revealed rather strikingly pathological changes, especially of the tick feeding on host immunized with 105KD purfied antigens the basal lamina became thinner, looser, and broken.

中华硬蜱叮咬纯化抗原、中肠抗原、唾液腺抗原免疫接种组和再次感染组宿主后，中肠可发生一系列明显的病理变化，尤以叮咬105KD纯化抗原组宿主后中肠病理变化最为严重。

They can also cause a neurological disorder known as tick paralysis.

有些硬蜱在叮刺吸血过程中唾液分泌的神经毒素可导致宿主运动性纤维的传导障碍，引起上行性肌肉麻痹现象，继而可导致呼吸衰竭而死亡，称为蜱瘫痪。
