Dr. Bart Pardon | Ghent University

Bart Pardon is a veterinarian, currently associated professor in large animal internal medicine at Ghent University (Belgium). He holds a Ph.D in veterinary sciences (Morbidity, Mortality and Drug use in veal calves with emphasis on respiratory disease, 2012) and is an EBVS certified specialist of the European college of Bovine Health Management (2016). Next to his teaching assignment, he runs a clinic for ruminant internal medicine. He and his team offer problem herd solving services to farmers and veterinarians, mainly in the area of calf health and infectious diseases. His research group focuses on respiratory health, especially in calves, with the eventual aim to rationalize antimicrobial use. Current projects include the development of rapid diagnostic tools, decision support tools and precision medicine applications for bovine respiratory disease. A significant portion of his past and present work deals with lung ultrasonography and Mycoplasma bovis, an interest that awoke from his Ph.D work. Bart attempts to keep close contact with practice, and puts effort in bringing tools with potential to the field, of which non-endoscopic bronchoalveolar lavage (nBAL) diagnostics and quick thoracic ultrasonography (qTUS) are two examples.
