【摘要】 [目的 ]证实福建省为泡囊狸殖吸虫的又一疫源地 ,补充该虫种的成虫、囊蚴形态研究。 [方法 ]分离蟹体内囊蚴 ,观测其形态并感染动物检获成虫观察。 [结果 ]在建瓯市发现泡囊狸殖吸虫 ,检查与溪蟹同一孳生地溪坑中的放逸短沟蜷 1873个 ,无阳性发现 ;福建拟钉螺和建瓯洱海螺的阳性率分别为 0 .10 % (1/6 95 )和 0 .2 5 % (5 /2 0 38) ,但因与斯氏狸殖吸虫混合感染 ,难以分辨有否泡囊狸殖吸虫尾蚴。第二中间宿主有 4种淡水蟹类 ,以福建华溪蟹为主。发现有斯氏狸殖吸虫单独感染或与泡囊狸殖吸虫两种囊蚴混合感染 ,感染率分别为 36 .8% (4 3/117)和 2 0 .5 % (2 4/117) ,检出囊蚴数分别为 80 6和 40个。将 12个及 4个泡囊狸殖吸虫囊蚴分别感染猫与大鼠 ,5 6d后在猫粪便中检及虫卵 ,6 8d后剖杀 ,检获成虫 6条 ,感染回收率 5 0 % (6 /12 )。 [结论 ]福建为泡囊狸殖吸虫又一疫源地 ,猫为适宜宿主 ,成虫形态特征与斯氏狸殖吸虫相似 ,定种以囊蚴的特征为根据。

【Abstract】 Objective]To prove that Fujian Province is also a natural focus of Pagumogonimus veocularis(Pv).[Methods]The adult worms were obtained from a cat fed with Pv metacercariae.[Results]Pv were found in Jianou,Fujian Province.All 1 873 Semisulcospira libertina showed negative.The positive rate of Tricula fujianensis and Erhaia jianouenensis were 0.10%(1/695) and 0.25%(5/2 038), respectively. The main crab host was S.fujianensis.Ps alone and mixed infection with Pv were found in the Sinopotamon ,the infection rates were 36.8%(43/117)and 20.5%(24/117), respectively. The numbers of the metacercariae were 806 and 40, respectively. A cat was infected with 12 metacercariae of Pv , eggs were found in the stool 56 days after infection,and 6 worms were found in the lungs 68 days after infection. [Conclusion]Fujian is one of the natural focus of Pv, cat is the adequate host. The fluke was identified as Pv according to the characteristics of the metacercariae.
