Knowing the players – the GI nematodes and what’s out there for treatment

Abstract

Gastrointestinal nematodes are the most costly and deadly parasites affecting small ruminants. There are nine genera that cause clinical disease in sheep and goats. Starting in the 1960s, modern chemical anthelmintics were developed to com­bat these gastrointestinal parasites. Now, there are four major classes of anthelmintics available for use in sheep and/or goats. These proceedings will discuss the parasites that currently af­fect small ruminants in the United States and the anthelmintics currently labeled to treat these parasites.
