Dr. Sierra Guynn will present “They have emerged! The Longhorned tick, Theileria orientalis, and the bovine”.   Theileriosis is a rapidly spreading tick-borne disease of cattle in the US. The biology and ecology of this protozoan and its vector, the Longhorned Tick (Haemaphysalis longicornis), are individually complex. With joint infestation and infection, they make it very difficult to elucidate a clear picture of the vector-pathogen-host relationship. 

Subsequently, the transmission, virulence, pathogenicity, epidemiology, and host immune response of cattle Theileriosis are not fully understood by researchers yet. This has led to a great deal of misunderstanding of the disease by veterinarians and their clients, creating husbandry and veterinary practices that are useless at a minimum with many causing harms to the health of the US cattle industry.  

Additionally, economic losses from increased mortality, abortions, decreased production in adults and young, and lack of confidence in regional cattle markets are increasing.  This presentation will explain the current situation of Theileriosis in cattle in the U.S., the life cycle of Theileria, the diagnosis of Theileriosis and prevention strategies for the disease and its vector.  

This webinar has been granted up to one hour of CE credit by RACE. Participants must be active members of the ACVPM or its partner organizations and must participate for at least 50 minutes of the webinar to receive a one hour CE certificate.
