Haemonchus contortus (Barber's pole worm or “BPW”) is the nematode “nemesis” of small
ruminant production systems in tropical and subtropical regions of the world. Its reputation …

Helminth parasites are a highly successful group of pathogens that challenge the immune
system in a manner distinct from rapidly replicating infectious agents. Of this group …

Helminth parasites are of considerable medical and economic importance. Studies of the
immune response against helminths are of great interest in understanding interactions …

The gastrointestinal nematode parasite Haemonchus contortus (H. contortus) is a resident of
tropical and subtropical regions worldwide that imposes significant production losses …

This paper examines the known immunological and genetic factors associated with sheep
resistance to infection by Haemonchus contortus. Such resistance is an inheritable genetic …

Background Polymorphonuclear neutrophil (PMN) and eosinophil extracellular trap (ETs)
formation has recently been described as an important host effector mechanism against …

Sheep were immunized by weekly oral infections with Haemonchus contortus for 9 weeks
followed by anthelmintic treatment. They were challenged either 9 or 22 weeks later with …

Serine protease inhibitors (serpins) are a superfamily of structurally conserved proteins that
inhibit serine proteases and play key physiological roles in numerous biological systems …

Sheep have a varying ability to resist infection with gastrointestinal nematodes. This ability is
due in part to genetic differences that exist between individuals. In order to define these …

Haemonchus contortus is one of the major nematode parasites causing substantial
economic losses in small ruminant farming worldwide. Recently, effectiveness of …
