OverviewAI-generated summary
T. A. Yazwinski's research focuses on the efficacy of anthelmintics, particularly in food-producing animals and ruminants. Yazwinski is an author on multiple guideline publications from the World Association for the Advancement of Veterinary Parasitology (WAAVP), including those concerning general guidelines for food-producing and companion animals, poultry, and ruminants (bovine, ovine, caprine). These publications address the evaluation of anthelmintic efficacy and offer reflections on the future development of such guidelines. Yazwinski's work also encompasses studies on parasite egg counts in cattle and the use of ivermectin. With a career publication count of 80 and an h-index of 18, Yazwinski has contributed significantly to the field of veterinary parasitology.
