The World Association for the Advancement of Veterinary Parasitology (WAAVP) was formally established on 16th August, 1963. It is the largest international veterinary parasitology organization in the world. WAAVP is a non-profit organization for scientists who study the parasites of animals, encompassing helminthology, protozoology and entomology. The Association encourages research in veterinary parasitology and to promote exchange of information and material amongst researchers, veterinary practitioners and animal health investigators. Apart from organizing scientific meetings, the WAAVP, which is affiliated with the World Veterinary Association, coordinates with various national, international and affiliated organizations, such as WHO, WOAH and FAO, in all matters concerning veterinary parasitology. The Association also plays important roles in preparing and publishing anthelmintic guidelines and participates in the development of the official guidelines for anthelmintic testing.
