Biological control of the nematode parasites of sheep and cattle by a nematode-trapping fungus

TL;DRAbstract

Chapters one to three review literature relevant to the thesis. The first chapter deals with the nature of nematode parasitic disease in livestock, the factors affecting its distribution and frequency of occurrence in Australia, and the production losses caused by these parasites. The second chapter deals with the effects of parasitism on the host animal including changes to metabolism and physiology caused by parasitic disease. The epidemiology of nematode-parasitic disease is examined and control methods discussed, particularly with regard to the past reliance on anthelmintics and the emergence of anthelmintic-resistant parasitic nematodes. Alternatives to the use of anthelmintics, including breeding for parasite resistance in livestock, vaccination and biological control, are discussed. Chapter three contains a review of the literature pertaining to nematophagous fungi and their potential as biological control agents against animal-parasitic nematodes. Chapter four introduces the ex
