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.

Experimental infection of calves with Haemonchus placei and Haemonchus contortus: Assessment of parasitological parameters [PDF]

Veterinary Parasitology, 2016
The present study evaluated the viability and possible effects of Haemonchus contortus infections in experimentally prime infected calves, comparing them to infections by Haemonchus placei. Ten male Holstein newborns were used. All calves were individually weighed for subsequent group formation, in which two animals were kept as a control group ...

The developmental phosphoproteome of Haemonchus contortus

Journal of Proteomics, 2020
Protein phosphorylation plays essential roles in many cellular processes. Despite recent progress in the genomics, transcriptomics and proteomics of socioeconomically important parasitic nematodes, there is scant phosphoproteomic data to underpin molecular biological discovery.

Epidemiological, Morphological, and Morphometric Study on Haemonchus spp. Recovered From Goats in Egypt

Frontiers in Veterinary Science, 2021
Goats can be infected by multiple groups of external and internal parasites. Haemonchus spp. are among abomasal parasites that can result in higher mortality and several considerable economic losses in goats.

Immunity to Haemonchus contortus and Vaccine Development

, 2016
Sheep are capable of developing protective immunity to Haemonchus contortus through repeated exposure to this parasite, although this immune protection is the result of a complex interaction among age, gender, physiological status, pregnancy, lactation, nutrition and innate and adaptive immunity in the host animal.
