=== General Life-Cycle ===
=== General Life-Cycle ===
The Rhabditoid worms have both free living and parasitic life cycles, making them unique amongst the veterinary nematodes. The parasitic life cycle is direct, infection occurs by ingestion of female L3 larvae from the ground or penetration through the skin. Once ingested the L3 larva moults to L4 and finaly to adult female worms in the small intestine. The free living form of the life cycle produces male and female worms on the ground and can happen for a number of generations without parasitism occuring.
In older animals there can be an accumulation of larvae beneath the skin and in abidominal viscera that are activated at pregnancy and can be passed to the young via the milk from the dam.
