Oestrus ovis is a very common parasite of sheep and goats in many countries. Its pathological effects are often underestimated because owners and veterinarians are used to seeing the infection. The study of natural and experimental infections has provided information about the evolution of the disease and its pathophysiology. Hypersensitivity is involved; the numbers of mast cells and eosinophils increase but changes in IgE have only recently been examined. Little is known about the development of immunity but it is possible that some animals are immunodeficient.
羊狂蝇是许多国家绵羊和山羊中非常常见的一种寄生虫。其病理影响常常被低估，因为羊主和兽医已习惯见到这种感染情况。对自然感染和实验性感染的研究提供了有关该疾病的发展及其病理生理学的信息。其中涉及超敏反应；肥大细胞和嗜酸性粒细胞数量增加，但IgE的变化直到最近才得到研究。关于免疫力的发展知之甚少，但有可能一些动物存在免疫缺陷。
