Understanding anthelmintic resistance in livestock using "omics" approaches

Area of Science:

• Veterinary Parasitology
• Molecular Biology
• Genomics

Background:

• Anthelmintic resistance (AR) in livestock, particularly gastrointestinal nematodes (GINs), is a significant global challenge.
• Improper drug use and genetic factors contribute to the rise of resistant helminth populations in sheep, goats, and cattle.
• Understanding the molecular basis of AR is crucial for developing effective parasite control strategies.

Purpose of the Study:

• To review the application of various "omics" technologies in elucidating the mechanisms of anthelmintic resistance in veterinary parasites.
• To highlight how genomics, transcriptomics, proteomics, and metabolomics advance the identification of AR biomarkers and causative genes.
• To discuss the challenges and future directions for "omics"-driven research in combating AR in livestock.

Main Methods:

• Review of current literature on "omics"-driven technologies applied to anthelmintic resistance.
• Analysis of genome scan, candidate gene, quantitative trait loci, transcriptomic, proteomic, and metabolomic approaches.
• Synthesis of findings related to molecular mechanisms, biomarkers, and genetic factors in AR.

Main Results:

• "Omics" technologies have significantly enhanced the understanding of molecular mechanisms underlying AR in parasitic worms.
• These approaches facilitate the identification of potential biomarkers and causative genes associated with parasite resistance.
• "Omics" data provide insights into regulatory networks and pathways governing AR development and host-parasite interactions.

Conclusions:

• "Omics" technologies are powerful tools for dissecting the complex molecular basis of anthelmintic resistance in livestock parasites.
• Continued application and integration of these technologies are essential for developing novel strategies to manage and overcome AR.
• Future research should focus on addressing the challenges and leveraging the prospects of "omics" for sustainable parasite control.
