Strongyloidea
General Appearance
Strongyloid nematodes share a a number of morphological features. They are bursate, meaning that the males have a copulatory bursa. They are realtively short, typically 1 - 5mm, but stout in appearance with a large buccal capsule at the anterior end. The head or anterior also usually carries characteristic features such as 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
