Abstract: Ovine haemonchosis is a highly pathogenic, blood-sucking parasitic disease caused by Haemonchus contortus, which mainly resides in the abomasum of small ruminants like sheep. The infected sheep can manifest as some chronic wasting symptoms, such as emaciation, anemia, weakness, and even death in an acute form. Haemonchosis is widespread in pastoral areas in China. Due to the absence of the safe and long-term vaccine and presence of serious anthelmintic resistance, high prevalence and incidence in grazing sheep flocks still persist, which led to significantly economic losses to the sheep husbandry. Accurate and reliable detection remains an essential component for diagnosing parasite infections, making treatment decisions, monitoring anthelmintic resistance and conducting epidemiological investigation. This paper reviews in detail the current research situations of existing detection methods for ovine haemonchosis, including pathogen detection, immunological detection and molecular detection. The advantages and limitations of the above detection methods were evaluated, and the developmental trend for future detection techniques was prospected as well. The purpose of this review is to provide some available information and guideline for the novel methods development and comprehensive prevention and control strategies against ovine haemonchosis.
