Dictyocaulus arnfieldi (Cobbold 1884) infects the respiratory tract of horses, donkeys, mules, hinnies and zebra. A review of the literature has been given by Round (1972). In the western hemisphere it is popularly believed that donkeys are the natural host and that horses become infected by association with infected donkeys. There is scant documentary evidence for this and, in the Soviet Union, patent infections may reach 70 per cent without mention of donkey association (Koulikov 1935, Borovkova 1948, Akramovskii 1952a). Poynter (1963) considered the infection to be rare in the United Kingdom although cases had been reported by Fletcher (1960) and Holmes (1960). The lack of precise data on this parasite has led to the assumption that it behaves like D filaria and D viviparaus of ruminants. Studies made in the United Kingdom have shown that there are some important differences (Round, 1972).
安氏网尾线虫（科博尔德，1884年）感染马、驴、骡、驴骡和斑马的呼吸道。朗德（1972年）已对相关文献进行了综述。在西半球，人们普遍认为驴是天然宿主，马因与受感染的驴接触而被感染。但几乎没有文献证据支持这一点，而且在苏联，明显感染率可达70%，却未提及与驴的接触情况（库里科夫，1935年；博罗夫科娃，1948年；阿克拉莫夫斯基，1952年a）。波因特（1963年）认为在英国这种感染很罕见，尽管弗莱彻（1960年）和霍姆斯（1960年）曾报告过病例。由于缺乏关于这种寄生虫的确切数据，人们假定它的行为与反刍动物的丝状网尾线虫和胎生网尾线虫相似。在英国进行的研究表明存在一些重要差异（朗德，1972年）。
