''Gasterophilus haemorrhoidalis'' (also called nose bot) is a species of the genus ''Gasterophilus'' that lays eggs on the lips and around the mouth of horses, mules and donkey, but also reindeer. In equidae, third-stage larvae attach to the stomach, but also to rectum, sometimes in great numbers. 〔Johannes Kaufmann, Parasitic Infections of Domestic Animals, Birkhäuser Verlag, Basel, Boston, Berlin, 1996, ISBN 3-7643-5115-2.〕 Heavy infestation can cause anal prolapse in foals and mules. In reindeer, the larvae grow in the sinuses and throat of the host animal, and are sneezed out in the spring. They do not parasitise humans. ==External links== *(GNWT - Environment and Natural Resources 'Nose Bot' page ) 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「Gasterophilus haemorrhoidalis」の詳細全文を読む スポンサード リンク
