裂头蚴病与增殖裂头蚴病

HUMAN SPARGANOSIS AND PROLIFERATING SPARGANOSIS IN CHINA

我国裂头蚴病据文献不完全记载有443例,遍及21个省市自治区,从东南沿海至西北新疆均有发现,尤以吉林、海南和福建等省为多见。其感染方式以敷贴蛙肉或吞食青蛙蝌蚪为主,幼虫还可从母体经胎儿外膜进入胎儿。食未煮熟的肉类致感染有所增多,是当前不容忽视。在台湾和广东还发现增殖裂头蚴病3例,患者因病情严重而致死。本病至今尚无理想的治疗方法,病原究属何种绦虫,尚待进一步探索。

The present author, as made a series of review concerning the etilogic agent and epidemiology of sparganosis, collected a total of 443 cases from previous literature in China. Surveys of these documents indicate that cases of sparganosis appeared in 21 provinces and autonomous region and the disease seems to be es pecially prevalent in Hainan, Guangdong, Fujian and Jilin provinces. In China the most infections could be attributted to the fact of raw infected frog flesh as poultice to the affected area, occupying 58.01%, or through the ingestion of raw cyclops, infected frog or infected snake flesh. Besides, a mewborn infant case was reported from Hubei province in 1983. The fetus infected by Sparganum mansoni through the chorion of placenta from his mother. To prevent infection in endemic areas, drinking raw water, swallowing fresh frog flesh and applying split frogs or frogs poultices should be avoided. Three cases of proliferating sparganosis had been reported from Taiwan in 1978 and 1984 and Guangdong in 1983. In these patients, the spargana were recovered by the thousands in the subcutaneous tissues, intermuscular tissues and viscera. The prognosis is bad. Nothing is known further about the life—cycle of this parasite.
