InfoSeries:  the Other Worms

While the barber pole worm (Haemonchus contortus) and coccidia (Eimeria spp.) are the primary gastro-intestinal parasites that affect small ruminants, there are many other worm parasites that can infect them and sometimes cause problems, individually or more often as part of mixed infections. This info series will detail these "other worms." Each info sheet will be written and reviewed by members of the American Consortium for Small Ruminant Parasite Control (ACSRPC), including at least one veterinarian.
