TRICHOSTRONGYLUS TENIUS
- Wide host range, but particularly important in grouse (and geese).
- Found in the intestine and caeca.
- Appearance, life-cycle and epidemiology of this worm very similar to that of the Trichostrongylus species of ruminants (hypobiosis can occur in winter).
- On moorland, the L3 accumulate in the heather tips eaten by grouse.
- Contributes to (but probably not the main cause of) the cyclical crashes in grouse populations.
- Treatment is achieved by putting out dishes of medicated grit.
- Grouse are particularly vulnerable in spring (when body condition is often poor after the winter):
- infection
→ reduced appetite and hypoalbuminaemia → reduced survivability and egg-laying.
