摘　　要：在室内越冬的中华绒螯蟹亲蟹上检出一种嗜腐性纤毛虫,经鉴定为蟹栖拟阿脑虫Paranophrgs carci-ni。在感染初期,多寄生于新蟹残肢等伤口组织处;在感染后期,侵蚀到蟹体,进入血淋巴,甚至可分布全身,致使器官组织受到严重损害,造成亲蟹死亡。对越冬亲蟹危害严重,短期内使亲蟹死亡率达40％左右。用15～30ppm的福尔马林或0.1～0.5ppm的孔雀石绿短期药治无效,改用25ppm的福尔马林或0.3～0.5ppm的孔雀石绿每天药浴8h,连续10～15d,病情基本得到控制。A kind of ciliates having a liking for humus was examined in the overwintering parent Chinese mitten - handed crab, Eriocheir sinensis in indoor. It was identified as Paranophrgs carini. In the early infestion, Paranophrgs carini parasitized in the wounded tissue of parent crab stump. In the later infestion, it eroded to the crab body, entered into haemolymph, and even distributed the whole body, which made serious damage to the organ tissues and finally caused the dead of parent crabs. It especially serious damaged to overwintering parent crab, causing the mortality up to 40% in a short period. Having no effect by using 15 - 30 ppm formalin or 0.1 -0.5 ppm malachite green in short period of bath, 25 ppm formalin or 0.3 - 0.5 ppm malachite green was bathed for 8 hours every day. After using 10 - 15 days in succession, the condition was basically controlled.
