=== '''''SYNGAMUS TRACHEA''''' ===
*The 'gapeworm' - an atypical strongyloid.
*Deep red in colour.
*'Y'-shaped as the smaller male is permanently attached to the female.
*Lives in the trachea.
*Wide host range, including many wild birds (rooks and crows commonly affected) as well as poultry and game birds.
*Causes respiratory distress ('''gapes'''), especially in young birds.
==== Life-Cycle ====
*The egg is like a typical strongyle egg, except that there is an operculum at each end.
*Infective larva develops inside the egg.
*Birds can be infected by ingesting:
**the larvated egg
**the larva after hatching out of the egg
**or by eating an earthworm (transport host) that has previously swallowed an egg or larva.
==== Epidemiology ====
Gapes is a common and serious problem in pheasant poults. A common sequence of events is as follows:
*Infected wild birds (e.g. crows):
→ droppings on ground
→ soil contaminated with ''Syngamus'' eggs
→ earthworms infected
→ reservoir of infection
→ eaten by pheasant poults reared on earth-floored pens in woodland
→ disease.
