High Burden of Goat Gastrointestinal Nematodes in South Ethiopia: Prevalence, Species Composition and Determinants of Infection. [PDF]

Vet Med Sci
Gastrointestinal nematode infection was highly prevalent amongst goats in Humbo district (South Ethiopia), affecting more than 70% of the animals examined. Young goats, poor body condition and goats raised in lowland agroecology were at greater risk of infection, highlighting the need for targeted parasite control strategies.

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.

Synthesis and Antiparasitic Activities of New Organometallic Derivatives of the Benzimidazole Anthelmintic Drugs. [PDF]

Chembiochem
Organometallic derivatization of existing drugs is a common strategy to look for new drug candidates. This work describes the derivatization of the benzimidazole anthelmintic scaffold, from the synthesis of the organometallic derivatives to the evaluation of their biological properties. It highlights a broad range of antiparasitic activities and leaves

Implementation of Targeted Selective Treatment (TST) in a Commercial Smallholder Sheep Flock: Reduction in Anthelmintic Expenditure. [PDF]

Vet Med Sci
ABSTRACT The adoption of targeted selective treatment (TST) is an alternative for the sustainable management of gastrointestinal nematodes in sheep. TST mitigates the development of anthelmintic resistance by reducing the number of animals drenched while preserving the parasite refugia population.

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.

Parasitological characteristics and tissue response in the abomasum of sheep infected with Haemonchus spp. Características parasitológicas e resposta tissular do abomaso em cordeiros infectados por Haemonchus spp.

Arquivo Brasileiro de Medicina Veterinária e Zootecnia, 2000
A histopathological study was conducted on the abomasal mucosa of 40 Corriedale sheep exposed to natural infection with Haemonchus spp. The sheep were allowed to graze on contaminated pastures for 14 days and, after being housed for 28 days, they were ...

Why is it important to correctly identify Haemonchus species? Por que é importante a identificação correta das espécies de Haemonchus?

Revista Brasileira de Parasitologia Veterinária, 2011
Parasitic gastroenteritis caused by Haemonchus spp. is a major cause of economic losses in the livestock industry because it impairs weight gain and increases mortality in cattle and small ruminants, especially in tropical and subtropical areas.
