Objectives of the Workshop

Typhlocolitis is an acute and severe disease of adult horses associated with high mortality. It occurs worldwide. The extensive size of their colon and caecum makes adult equine colitis an often very acute and life-threatening illness. Although progress has been made in identifying causes, some 60% of cases still have no known cause. This makes diagnosis, treatment and prevention both challenging and frustrating.  

There is a need to increase collaboration and effort to improve understanding of acute colitis in adult horses, particularly focused on infectious causes.  New information regarding the microbial communities in the horse gut using next generation sequencing technology (NGS) could help unravel the causes of acute colitis in adult horses and improve how we control the disease.

The purpose of the Havemeyer Workshop of Acute Colitis in Adult Horses is:

To stimulate research into this important and relatively poorly characterized severe illness of horses, to promote collaborative and multicenter studies to develop guidelines for best diagnostic standards and evidence-based treatment protocols, and to integrate and assess the clinical significance of intestinal microbiome studies that are currently occurring in equine research centers throughout the world.

Topics addressed in the Workshop will include:

What are the most common causes of colitis in adult horses? What is known about the predisposition of adult horses to colitis? What are the optimal diagnostic tests for colitis in adult horses? What are the best prognostic indicators for outcome of colitis in adult horses? What are microbiome studies telling us about the causes, prevention and treatment of colitis? What treatments are most effective for colitis in adult horses? What is the best way to prevent colitis in adult horses? How can we take a collaborative approach to understanding and controlling adult colitis in horses? What are the most important research priorities to understand colitis in adult horses better?
