Parasitic gastroenteritis is one of the major causes of productivity loss in sheep and goats. This report records two studies of the helminth fauna from post-mortem examination. The first study, performed on the digestive tract of 72 sheep from a central part of Sicily in a high hill village (1,360 meters above sea level), between April 1996 and March 1997, showed an infection rate of 78%. The second study targeted goats from the western part of Sicily and showed an infection rate of 90%. For sheep, a total of 23 species of helminths were identified belonging to the family of Trichostrongyloidea, with the genera Haemonchus, Ostertagia (Teladorsagia), Trichostrongylus, Cooperia, and Nematodirus; Strongilolidea with the genera Oesophagostomum and Chabertia: Ancylostomidea with Bunostomum; and Tricuridea with Tricuris. Teladorsagia circumcincta was the most common in the sheep abomasum, Bunostomum trigonocephalum and Trichostrongylus spp. in the small intestine, and Chabertia ovina and Trichuris ovis in the large intestine. For goats, a total of 12 species were isolated in the abomasum with Teladorsagia circumcincta and Trichostrongylus axei the most common species. In the small intestine, five species were isolated and Trichostrongylus capricola was the dominant species. T. ovis and O. venulosum were dominant in large intestine and in the cecum. We also found species belonging to other ruminants such as O. ostertagi (in cattle) and S. kolchida and O. leptospicularis (in wild ruminants).
