=== '''''TRICHOSTRONGYLUS TENIUS''''' ===

===Scientific Classification===

*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):

→ reduced appetite and hypoalbuminaemia

 

→ reduced survivability and egg-laying.

==Hosts==

Game birds, chickens, ducks, geese, and turkeys.

 

The eggs are around 75μm in length, with a thin, smooth shell.

 

The life-cycle and epidemiology of ''T. tenius'' is very similar to that of the ''Trichostrongylus'' species of ruminants, and hypobiosis can occur in winter. Eggs are past out in the faeces.  The larvae develop in the heather, and are ingested by a host e.g. a grouse, when feeding on the heather. Worms are capable of surviving for up to 2 months, and are capable of causing damage to the intestine and the caecum.
