摘要

本文研究了日本大型田鼠斑姬鼠(Apodemus speciosus)寄生区系的时空变化,并以此作为评价福岛第一核电站事故放射性物质释放生物效应的模型。从事故发生之前(1992年)和之后(2012年和2014年)捕获的30只老鼠身上收集了寄生虫。鉴定出寄生虫5种;其中,异线虫(Heterakis spumosa, Nematoda)仅在事故发生前检出,而coreensis (Raillietina coreensis, Cestoda)仅在事故发生后检出。这种现象可能反映了意外引起的环境变化影响了副毒性和中间寄生宿主的丰度。在形态学方面,所有分离的寄生虫均未观察到任何畸形。

Temporal Changes in the Parasite Fauna of the Large Japanese Field Mouse Apodemus speciosus in the Radioactive Contaminated Zone of Fukushima
We assessed the temporal changes in the parasite fauna of the large Japanese field mouse Apodemus speciosus, which served as a model to evaluate the biological effects of radioactive materials released upon the Fukushima Daiichi Nuclear Power Plant accident. Parasites were collected from 30 mice trapped before (1992) and after (2012 and 2014) the accident. Five species of parasites were identified; among these, Heterakis spumosa (Nematoda) was detected only before the accident and Raillietina coreensis (Cestoda) was detected only after the accident. This phenomenon may reflect accident-induced environmental changes affecting the abundance of paratenic and intermediate parasitic hosts. Regarding morphology, no malformations were observed in any of the isolated parasites.
