本文报道了一个夏季某湖泊中丁鱼的自然感染情况。感染率为57%，平均感染强度为50. digencans沿着宿主肠道的分布在后半部分显示出最大值，这可以通过其他蠕虫物种的存在进行修改。在早春捕获并保存在实验室的坦奇在整个夏天都保持着自然感染。饥饿的主机在两个月内造成的感染消失。实验表明，后尾蚴进入丁鱼肠道后，1小时内即可脱囊。在体外，囊肿与丁鱼胆汁接触后在15秒内打开。其他几种鲤科鱼类的胆汁在60秒内引起脱囊。在感染后7 ~ 10天，在丁鱼粪便中出现虫卵。A.丁可在丁鱼的肠内分解，其卵随粪便排出。
ABSTRACT The natural infection of tench by Asymphylodora tincae in a lake was studied during one summer season. The incidence of infection was 57%, the mean intensity about 50. The distribution of the digencans along the host's intestine showed a maximum in the second half; this could be modified by the presence of other helminth species. Tench caught in early spring and kept in the laboratory retained their natural infection throughout the summer. Starvation of hosts during two months caused disappearance of the infection. Experiments showed that metaecrcariae, introduced into the intestine of tench, can excyst within one hour. In vitro, cysts in contact with tench bile opened within 15 seconds. Bile of several other cyprinid fisli species caused excystment within 60 seconds. Asymphylodora eggs appeared in tench faeces 7 to 10 days after infection. Progenetic specimens of A. tincae probably disintegrate in the intestine of the tench and their eggs arc passed out with the faeces.
