Category:Trichinelloidea

The common feature of members of this group is that the oesophagus is a column of doughnut-shaped cells. They are only distantly related to the other nematode groups and so drugs developed primarily for controlling strongyle and ascarid worms are often less effective against these.

There are just three genera of veterinary importance:

1. Trichuris (the whipworms)
2. Capillaria
3. Trichinella
