title: Research needs on internal parasites of horses.
abstract: The importance of the horse industry to the economy of the United States and the impact of parasitic infections on the industry are well documented. However, contemporary research activity on internal parasites of horses has not kept pace with growth of the horse population. Parasitic infections are a major facet of enteritis and colic in horses. Parasites are also associated with poor growth and development, respiratory tract disease, dermatitis, and CNS lesions. Babesia infections remain a threat to horses imported from some regions of the world. Most research activity has dealt with the development of new antiparasitic drugs. Efforts must be made to integrate these studies with observations on the bionomics of parasites in different regions and under different management conditions into more effective and less costly integrated parasite control programs. Increased research activity concerning the pathogenesis and immune response to equine parasitic infections is also necessary. A better understanding of these factors will lead to improved diagnostic, treatment, and preventative measures. Specific research objectives designed to produce short-term and long-term benefits are suggested.
