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:
#''[[Trichuris]]'' (the whipworms)
#''[[Capillaria]]''
#''[[Trichinella]]''
== ''Capillaria'' ==
*Similar to ''Trichuris'', but the difference between anterior and posterior ends of the body is not so pronounced
*Some species have direct life-cycles, others use intermediate or transport hosts
*Species have different predilection sites
*Of greatest importance in birds, although species do occur in the urinary bladder and liver of cats and dogs
== ''Trichinella'' ==
*This is known as the "worm that thinks its a virus"
*It is an important zoonosis
*It is covered in greater detail
[[Trichuris]]
*''Capillaria aerophila'' in [[Respiratory Parasitic Infections - Pathology#Capillaria aerophila|respiratory disease]] of cats and dogs
*''Trichinella'' in [[Muscles Inflammatory - Pathology#Nematodes|myositis]]
