Die Trichostrongylinae sind eine Unterfamilie der Trichostrongyliden mit etwa 430 Arten in 56 Gattungen.[1] Sie haben sich vermutlich im Eozän als Parasiten bei Vögeln herausgebildet und haben sich später auch an Säugetiere angepasst.[2]
Merkmale
Das wichtigste morphologische Unterscheidungsmerkmal bei den Trichostrongyloidea ist der Bau der Bursa copulatrix. Diese ist bei den Trichostrongylinae vom Typ 1-4 oder 1-1-3. Die Rippen 3 sind größer als die Rippen 5. Die Rippe 4 und / oder 8 erreichen den Hinterrand der Bursa. Die Mundöffnung ist von drei Lippen umgeben, ein peribukkaler Ring fehlt. Die Vulva ist längs orientiert.[2]

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.
