Strongyloidea
General Appearance
Strongyloid nematodes share a a number of morphological features. They are bursate, meaning that the males have a copulatory bursa.
- Bursate
- Large buccal capsule
- Relatively short (typically 1-5cm) but stout
- Heads often have characteristic features - teeth or cutting plates
General Life-Cycle
- Like that of the trichostrongyloids (eggs are also 'typical strongyle eggs'), but:
- L3 → L4 → adult (typically occurs in the large intestine)
- Larvae penetrate the mucosal wall and elicit nodule formation
- Larvae of some species migrate around the body
- Prepatent period varies between species from 3 weeks to over 6 months
Peritonitis in sheep by penetration of intestines by larvae of Oesophagostomum columbianum
Strongylus edentatus and Strongylus equinus migrate through Peritoneal Cavity - Parasitic Pathology
Stephanuris dentatus causes peritonitis in pigs Peritoneal Cavity - Parasitic Pathology and may cause cysts in the pancreas
