| Popis: | A helminthological survey was performed on 75 individuals of Tancho, Grus japonensis, from Hokkaido, Japan. A total of seven helminth species, including five nematode (Baruscapillaira sp., Contracaecum sp., Paracuaria adunca, Syncuaria sp., Viktorocara sp.) and two trematode (Echinostoma gotoi, Apatemon gracilis) species were obtained from 57.3% of the cranes, and E. gotoi was the most common encountered. Among the above helminths, all helminths except for E. gotoi were the first host records for G. japonensis worldwide, and Syncuaria sp. was the first geographical record from Japan. Since the acuariid nematodes including the genera Paracuaria, Syncuaria and Viktorocara are known to cause ulcerative ventriculitis and/or enteritis in bird alimentary tracts, monitoring of helminths is recommended in this endangered crane species. 2000年から2009年の間に北海道内各地で傷病個体として回収された後、斃死したタンチョウ75個体の寄生蠕虫類保有状況を調査した。57.3%から線虫5種(Baruscapillaira sp., Contracaecum sp., Paracuaria adunca, Syncuaria sp., Viktorocara sp.)および吸虫2種(Echinostoma gotoi, Apatemon gracilis)の計7種の蠕虫類のいずれかが検出された。E. gotoiを除く6種はタンチョウから初記録であり,Syncuaria sp.は日本初記録であった。得られた蠕虫類の中にはParacuada属, Syncuaria属およびViktorocara属など,消化管潰瘍や腸炎の原因となる線虫が含まれたため,絶滅危惧種であるタンチョウの保護管理上,今後寄生虫のモニタリングが必要であると考えられた。 |
