PCR primers for straightforward differentiation ofHaemonchus contortus, Haemonchus placeiand their hybrids [PDF]

Journal of Helminthology, 2017
AbstractHaemonchus contortusandHaemonchus placeiare among the major parasites of small ruminants and cattle. Although infection with these nematodes is host-specific, withH. placeipredominating in cattle andH. contortusin sheep, cross-infections are observed in areas where both parasites are sympatric, and hybrid offspring can occur.

Haemonchus placei and Haemonchus contortus are distinct species based on mtDNA evidence

International Journal for Parasitology, 1997
Debates continue over the extent to which the parasitic trichostrongylids Haemonchus placei and Haemonchus contortus hybridise in nature, and whether they deserve species status. Mitochondrial ND4 gene sequences from individuals of each putative species collected from populations around the United States indicate that the two species are highly ...

Peptidomics of Haemonchus contortus [PDF]

ACS Omega, 2021
The nematode Haemonchus contortus (the barber's pole worm) is an endoparasite infecting wild and domesticated ruminants worldwide. Widespread anthelmintic resistance of H. contortus requires alternative strategies to control this parasite. Neuropeptide signaling represents a promising target for anthelmintic drugs.
