An expert committee, appointed by the Executive Committee of the World Association for the Advancement of Veterinary Parasitology (W.A.A.V.P.), presents its proposal for uniform and proper terminology to denominate animal parasitic diseases or infections. In principle, the disease name is constructed solely by the suffix -osis, which is added to the stem of the name of the parasite taxon, formed from the nominative of the taxa. Standardized nomenclature of animal parasitic diseases (SNOAPAD) is meant as a guideline for general use, to improve the clarity of scientific communication. It should be especially useful in promoting effective usage of computerized data retrieval services.
