- This is the most important condition causing cattarhal enteritis worldwide.
- Seen mainly in grazing animals.
- Especially in sheep - causes large production losses.
- Particularly problematic since some parasites are resistant to anthelmintics.
- Especially in Australia.
- e.g. Nematodirus and Trichuris.
- A pre-patent period of 7-10 days is followed by the development of greenish diarrhoea.
- The gut becomes filled with greenish soupy material.
- Oedema and hyperaemia of mucosa occurs.
- In young animals, parasites can cause serious disease and even death.
