The control of gastrointestinal nematodes relies at present mostly on antihelmintic treatments using synthetic molecules. This approach, however, has led to the appearance of resistance to some types of antihelmintics which, together with the need to cut down on the use of chemicals, has fostered the development of other control methods, such as biological control, which is the use of living organisms that are naturally antagonistic to an unwanted species. Among the natural enemies of nematode parasitic larvae is the microfungus Duddingtonia flagrans. Research has shown the ability of this fungus to reduce the number of nematode larvae in faeces, the ability of its chlamydospores to survive the passage through the gastrointestinal tract of livestock and, moreover, to keep its germinative ability, thus facilitating the development of formulations. The present review looks at the species currently used and the different ways of administering already tested nematophagous fungi.
目前，胃肠道线虫的防治主要依赖于使用合成分子的驱虫治疗。然而，这种方法导致了对某些类型驱虫药产生抗性，再加上需要减少化学品的使用，这促使了其他防治方法的发展，如生物防治，即利用对有害物种具有天然拮抗作用的生物。线虫寄生幼虫的天敌之一是微真菌——达丁顿草菌。研究表明，这种真菌有能力减少粪便中线虫幼虫的数量，其厚垣孢子能够在牲畜胃肠道中存活，并且还能保持其萌发能力，从而便于制剂的开发。本综述探讨了目前使用的物种以及已测试的食线虫真菌的不同给药方式。
