Background:

Haemonchus contortus, a parasitic nematode, causes significant economic losses in small ruminants globally.
Anthelmintic drug resistance in H. contortus is a critical and growing problem.
Limited understanding of H. contortus molecular biology has hindered control efforts.

Purpose of the Study:

To provide a background on Haemonchus contortus and haemonchosis.
To review the progress and challenges in transcriptomics and genomics of H. contortus.
To explore the implications of new genomic and transcriptomic data for understanding parasite biology and developing interventions.

Main Methods:

Review of existing literature on H. contortus, including transcriptomics before genome availability.
Analysis of progress in H. contortus genomics, focusing on two draft genomes.
Examination of developmental transcriptomes to understand parasite life cycle stages.

Main Results:

Significant advancements in understanding H. contortus molecular biology through transcriptomics and genomics.
Insights into the free-living and parasitic stages of the H. contortus life cycle.
Identification of potential targets for new interventions against haemonchosis.

Conclusions:

Genomics and transcriptomics are accelerating research on Haemonchus parasites.
These technologies are crucial for developing novel strategies to combat anthelmintic resistance.
New interventions are needed to address the challenges posed by H. contortus in livestock.
