STRONGYLOIDES WESTERI
General
- Rhabditoid, small intestine.
- Commonest in foals <6months old.
- FIRST PARASITE TO WHICH FOALS ARE EXPOSED.
Morphology
- <6mm long, similar to small trichostrongyles.
- Only female worms parasitic.
- Long oesophagus (up to one third of body length).
Life-Cycle
- Parasitic and free-living (non-parasitic) phases.
- Prepatent period 1week (embryonated egg, 50-60µm).
- Infection by:
- ingestion of L3 in mare's milk or grass; and
- skin penetration.
Pathogenicity
- Foals - severe enteritis, diarrhoea (heavy burdens).
- Adults - normally immune; may act as carriers, e.g. mare.
Control
- Regular anthelmintic treatment.
- Good hygiene.
