Die Trichostrongyloidea sind eine ehemalige Überfamilie der Fadenwürmer, die im Magen-Darm-Trakt von Vögeln, Beuteltieren, Hasenartigen, Nagetieren, Wiederkäuern und Primaten parasitieren. Lippen, Mundhöhle und Kopfbläschen sind nicht ausgebildet. Die Bursa copulatrix ist vom Typ 1-3-1. Der Uterus ist paarig.[1] Nach neuerer Systematik sind sie zur Familie Trichostrongylidae herabgestuft.[2]
Die Überfamilie wurde in drei Familien gegliedert, die aktuell nur noch Unterfamilien sind:[3]
- Cooperiidae
- Haemonchidae
- Trichostrongylidae

Barber's pole worm is a roundworm that grows up to 30 millimetres long and sucks blood from the lining of the sheep's stomach,causing anaemia. Symptoms include swelling under thejaw (bottle jaw), weight loss and reduced wool growth and tensile strength. In lactating ewes, milk production can decline. More severe infections can prove fatal. Female worms have a red and whitestriped appearance, from which the common name 'barber's pole' worm is derived. Barber's pole worms are the highest egg producers of all sheep worms — females can lay up to 10,000 eggs per day.
