The future of veterinary diagnostics with Dr. Anatoliy Trokhymchuk

Épisode 32

jeudi 6 juillet 2023 • Durée 09:36

In this episode, I recorded a presentation by Dr. Anatoliy Trokhymchuk at the annual field day of the Livestock and Forage Centre of Excellence at the University of Saskatchewan. Anatoliy is a veterinarian and epidemiologist who serves as the Chief Scientific Officer at our local veterinary diagnostic laboratory (Prairie Diagnostic Services). Anatoliy will describe some of the new technology that may make it possible to learn what bacteria or viruses are present in a swab in a much faster manner than traditional laboratory techniques. New technology might make it possible to perform DNA fingerprinting for bacteria and viruses on the farm or at your local veterinary clinic rather than sending the sample into the diagnostic lab and waiting 5-7 business days for an answer to come back.
