In this study, 858 novel long non-coding RNAs (lncRNAs) were predicted as sensitive and resistant strains of Haemonchus contortus to ivermectin. These lncRNAs underwent bioinformatic analysis. In total, 205 lncRNAs significantly differed using log2 (difference multiplicity) > 1 or log2 (difference multiplicity) <  - 1 and FDR < 0.05 as the threshold for significant difference analysis. We selected five lncRNAs based on significant differences in expression, cis-regulation, and their association with the Gene Ontology and Kyoto Encyclopedia of Genes and Genomes pathways. These expressions of lncRNAs, namely MSTRG.12610.1, MSTRG.8169.1, MSTRG.6355.1, MSTRG.980.1, and MSTRG.9045.1, were significantly downregulated. These findings were consistent with the results of transcriptomic sequencing. We further investigated the relative expression of target gene mRNAs and the regulation of mRNA and miRNA, starting with lncRNA cis-regulation of mRNA, and constructed a lncRNA-mRNA-miRNA network regulation. After a series of statistical analyses, we finally screened out UGT8, Unc-116, Fer-related kinase-1, GGPP synthase 1, and sart3, which may be involved in developing drug resistance under the regulation of their corresponding lncRNAs. The findings of this study provide a novel direction for future studies on drug resistance targets.

Ivermectin induces oxidative stress and mitochondrial damage in Haemonchus contortus.

Key Laboratory of Grass-Feeding Livestock Healthy Breeding and Livestock Product Quality Control, Veterinary Research Institute, Inner Mongolia Academy of Agricultural and Animal Husbandry Sciences, Hohhot 010031, PR China. Electronic address:

Haemonchus contortus poses a severe threat to livestock, leading to substantial economic losses. The extensive use of ivermectin (IVM), an effective anthelmintic drug, has resulted in the development of resistant strains, reducing the drug's effectiveness and making disease management more challenging. Hence, understanding the underlying mechanisms of IVM resistance is crucial.

The aim of the study was to purify and characterise recombinant proteins with the potential as an anti-parasite vaccine. Full-length cDNAs encoding seryl-tRNA synthetase (srs-2) were cloned from Haemonchus contortus (HcSRS-2) and Teladorsagia circumcincta (TcSRS-2). TcSRS-2 and HcSRS-2 cDNA (1458bp) encoded proteins of 486 amino acids, each of which was present as a single band of about 55 kDa on SDS-PAGE.

Article Synopsis
  • The barber's pole worm is a harmful gastric nematode affecting ruminants, leading to significant economic losses in livestock globally.
  • Recent studies have utilized the well-mapped genome of the MHco3(ISE).N1 strain for research, but a genetic comparison with the Haecon-5 strain and others had not been done until now.
  • The newly assembled mitochondrial genome of Haecon-5 revealed multiple single nucleotide polymorphisms, indicating notable genetic variations, highlighting the need for further research into their biological implications and nuclear genomic differences.

Chromosome-contiguous genome for the Haecon-5 strain of Haemonchus contortus reveals marked genetic variability and enables the discovery of essential gene candidates.

Millions of livestock animals worldwide are infected with the haematophagous barber's pole worm, Haemonchus contortus, the aetiological agent of haemonchosis. Despite the major significance of this parasite worldwide and its widespread resistance to current treatments, the lack of a high-quality genome for the well-defined strain of this parasite from Australia, called Haecon-5, has constrained research in a number of areas including host-parasite interactions, drug discovery and population genetics. To enable research in these areas, we report here a chromosome-contiguous genome (∼280 Mb) for Haecon-5 with high-quality models for 19,234 protein-coding genes.
