Haemonchus placei

The Barber’s Pole worm

a parasitic nematode (roundworm) that primarily affects cattle and other ruminants. It belongs to the family Trichostrongylidae and is often referred to as the "barber's pole worm" due to the distinctive coloration of its female. This parasite resides in the abomasum (the true stomach) of its hosts and can cause significant economic losses in the livestock industry due to its role in anemia and weight loss.
