Moreover, this disease is zoonotic which means the parasite can transmit disease from animals to humans. Eustrongylidosis is named after the causative agent Eustrongylides and typically occurs in eutrophicated waters where concentrations of nutrients and minerals are high enough to provide ideal conditions for the parasite to thrive and persist. Because eutrophication has become a common issue due to agricultural runoff and urban development, cases of Eustrongylidosis are becoming prevalent and hard to control. Eustrongylidosis can be diagnosed before or after death by observing behavior, clinical signs and performing fecal flotations and necropsies. Methods to control Eustrongylidosis include preventing eutrophication and providing hosts with uninfected food sources in aquaculture farms. Parasites are known to be indicators of environmental health and stability and should therefore be studied further to better understand the parasite’s life cycle and how it affects predator-prey interactions and improve conservation efforts. == Cause == Eustrongylidosis is caused by several species of roundworms. The nematodes are red, large, and easily noticeable and are characterized by the absence of a posterior sucker.〔 These roundworms cause a high mortality rate in nesting egrets and other wading birds, including other coastal populations.〔National Wildlife Health Center, 1999〕 The parasite was first detected in fish. The parasite is then transferred from the fish to the waterfowl when the bird is eating the fish. After consumption, the parasite perforates through the stomach lining often resulting in the death of the host.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Eustrongylidosis」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
