Alexander Zakhartchouk is an adjunct professor in the Department of Veterinary Microbiology at the Western College of Veterinary Medicine (WCVM), University of Saskatchewan, Saskatoon, Saskatchewan.

Dr. Zakhartchouk participated in the teaching of the Viral Pathogenesis course offered by the University of Saskatchewan for graduate students. He has supervised 4 PDFs, 6 technicians and a graduate student.  

Research Interests

Dr. Zakhartchouk has been involved in molecular characterization of non-human adenoviruses (porcine adenovirus-3 and bovine adenovirus-3), with the aim to develop them as live vaccine vectors for animals and humans. He demonstrated that mucosal immunization of calves with recombinant bovine adenovirus-3 induced protective immunity to bovine herpesvirus-1. Also, he developed a recombinant E1-deleted porcine adenovirus-3 as an expression vector and worked on a new vaccine against measles. After the SARS epidemic occurred, Dr. Zakhartchouk became involved in developing a vaccine against SARS.

Current research interests of Dr. Zakhartchouk include development of novel vaccines for porcine reproductive and respiratory syndrome virus (PRRSV) and porcine epidemic diarrhea virus (PEDV). In addition, he is interested in the characterization of virus-host cells interactions.
