目的：对云南兰坪防治绦虫病试点进行病原学调查，查明流行虫种与流行环节。方法：对该地２例患者作驱绦虫治疗，获取成虫，洗净，取孕节直接灌喂本地圈养的健康断乳猪５头，并设健康断乳猪２头作对照，分别隔离饲养观察。２－３个月后，解剖观察各组织器官，查找囊尾蚴。另对该地放养的自然感染疫猪１头同法解剖观察。结果：驱出成虫４条，取头节和孕节观察，形态特征与牛带绦虫相似。取其孕节人工感染猪，于２头猪的肝脏、大网膜及肠系膜查见囊尾蚴２３个。自然感染猪１头，经解剖仅在肝脏及大网膜查见囊尾蚴３个。取囊尾蚴直接压片、染色、镜检，见成熟囊尾蚴原头节均有钩，具顶突及４个吸盘，与猪囊尾蚴相似。根据形态特征及囊尾蚴寄生部位鉴定为亚洲无钩绦虫。结论：亚洲无钩绦虫感染者在云南省首次发现。 OBJECTIVE: To conduct an etiological investigation of the pilot test for the prevention and control of taeniasis in Lanping, Yunnan Province, and to identify the prevalence of epidemic species and epidemics. Methods: Two patients in this area were treated with tapeworms, and adults were obtained. After washing, the gestation section was directly infused with 5 healthy weaned pigs, and 2 healthy weaned pigs were used as controls, respectively. . 2-3 months later, anatomical observation of various tissues and organs, look for cysticerci. Another natural infection of the stocking pigs in the same place an anatomical observation. Results: 4 adults were expelled, and the first day and the second day of pregnancy were observed. The morphological characteristics were similar to those of Taenia saginata. Take the artificial infection of their pregnant pigs, in 2 pigs liver, omentum and mesenteric check cysticercosis 23. Natural infection of a pig, anatomized only in the liver and omentum cysticercosis seen three. Cysticercus cellulosae direct compression, staining, microscopic examination, see the mature head of cysticercosis are hook, with the sudden protrusion and 4 sucker, similar to Cysticercus cellulosae. According to morphological characteristics and cysticerci parasitic sites identified as Asian hookworm. Conclusion: The Asian patients without hookworm infection were found for the first time in Yunnan Province.
