A mixed amplicon metabarcoding and sequencing approach for surveillance of drug resistance to levamisole and benzimidazole in Haemonchus spp

bioRxiv, 2023
Anthelmintic resistant parasitic nematodes present a significant threat to sustainable livestock production worldwide. The ability to detect the emergence of anthelmintic resistance at an early stage, and therefore determine which drugs remain most ...

A Review: Haemonchus contortus Infection in Pasture-Based Sheep Production Systems, with a Focus on the Pathogenesis of Anaemia and Changes in Haematological Parameters

Animals, 2022
Simple Summary Infection with Haemonchus contortus parasites (haemonchosis) is an important cause of anaemia in sheep. Haemonchosis is a global problem, although sheep that are kept in warm, high rainfall environments are at the greatest risk of ...

Anthelmintic Effect of Chitosan-Encapsulated Bromelain on Gastrointestinal Nematodes in Naturally Infected Goats in Kenya. [PDF]

J Parasitol Res
The emergence of anthelmintic resistance calls for the development of alternatives, including medicinal plant extracts. The present study was aimed at assessing the efficacy of chitosan‐encapsulated bromelain (EB) as an oral solution drug against GIN in goats.

Susceptible trichostrongyloid species mask presence of benzimidazole-resistant Haemonchus contortus in cattle

Parasites & Vectors, 2021
Background Benzimidazole (BZ) anthelmintics are widely used to control infections with parasitic nematodes, but BZ resistance is an emerging threat among several nematode species infecting humans and animals.

Genomic and transcriptomic variation defines the chromosome-scale assembly of Haemonchus contortus, a model gastrointestinal worm

Communications Biology, 2020
Haemonchus contortus is a globally distributed and economically important gastrointestinal pathogen of small ruminants and has become a key nematode model for studying anthelmintic resistance and other parasite-specific traits among a wider group of ...

New codon 198 β-tubulin polymorphisms in highly benzimidazole resistant Haemonchus contortus from goats in three different states in Sudan

Parasites & Vectors, 2020
Benzimidazole (BZ) resistance in gastrointestinal nematodes is a worldwide problem for livestock production, particularly in small ruminants. Assignment of the emergence of resistance using sensitive and reliable methods is required to adopt the correct ...

Artemisia cina 30 CH homeopathic treatment against Haemonchus contortus

Revista Mexicana de Ciencias Pecuarias, 2020
The anthelmintic resistance problem is widely recognized in sheep production. Therefore, new methods of control against gastrointestinal nematodes (GIN) need to be integrated. The aim of this work was to assess the toxicity of A.

Research progress and limitation analysis of RNA interference in Haemonchus contortus in China

Frontiers in Veterinary Science, 2023
Haemonchus contortus is a highly pathogenic and economically important parasitic nematode that affects small ruminants worldwide. While omics studies hold great promise, there are fewer research tools available for analyzing subsequent gene function ...

Avaliação endoparasiticida das moléculas Moxidectina e Ivermectina contra nematódeos gastrintestinais de ovinos naturalmente infectados

Pubvet, 2019
As helmintoses gastrintestinais em ovinos são o principal fator que interfere na produção e criação destes animais e se não tratada de forma adequada, pode levar ao desenvolvimento de resistência, resultando em prejuízos ao produtor.
