The rising threat of equine piroplasmosis will be discussed as part of a lecture series organised by Washington State University.
Authorities have been fighting to contain an outbreak of the tick-borne protozoal infection, with more than 300 cases, nearly all of which are in Texas.
However, linked cases have been found in about a dozen states, and some cases detected in screening appeared unrelated to the index premises in Texas.
The university describes equine piroplasmosis as a serious new threat to the multi-billion dollar horse industry in the US.
Washington State University scientists are conducting critical research to stem the spread of the disease,a nd others, through development of knowledge and novel vaccines.
They are also exploring ways to possibly clear the disease from infected horses and to improve diagnostic techniques.
Dr Don Knowles, leader of the US Department of Agriculture's Animal Disease Research Unit of the Agricultural Research Service, will deliver the lecture in Seattle on March 23.
He is professor of veterinary medicine at the university, and at the forefront of collaborative efforts to promote global equine health through innovative research.
The Innovators Lecture series will highlights the University's research achievements and promote informed discussion.
