摘要/Abstract

摘要： 　　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。

Abstract: 　AIM: To investigate the aetiology, species and epidemiological factors of Taenia infection in a pilot area of Lanping County, Yunnan Province.METHODS: Two patients with taeniasis were treated with antiscolex capsule and praziquantel, respectively. Five local weaning pigs free from tapeworm infection were fed with gravid proglottids obtained from the patients. After 2-3 months, the pigs were necropsied to examine cysticerci. In addition, one pig naturally infected with Taenia was treated as well. RESULTS: Based on morphological characteristics of the scolex and gravid proglottid of four tapeworms obtained from the patients, the worms were similar to T.saginata. 23 cysticerci recovered from two experimentally infected pigs were found in the livers, omentum majus and mesenterium, and 3 cysticerci were found in the liver and omentum majus in a naturally infected pig as well. The protoscolex of mature Cysticercus had two rows of rudimentary hooklets, one rostellum and four acetabula resembling to C.cellulosae. According to morphological characteristics and the location of cysticerci, the tapeworm was identified as Taenia saginata asiatia. CONCLUSION: T.saginata asiatica infection was first reported in Yunnan Province.
