PATHOLOGY

Detailed explanation-1: -PGE is primarily a disease of lambs and first season grazing cattle. The most profound effect of parasitism in both sheep and cattle is the sub-clinical production losses (i.e., not visually obvious), the true extremity of which farmers are unlikely to be aware (Waller and Thamsborg, 2004).

Detailed explanation-2: -In the case of parasitic gastroenteritis, the two most common causes are from Giardia and Cryptosporidium. The Giardia parasite is usually found in soil, food, or water that has been contaminated with feces (poop) from infected animals or humans.

Detailed explanation-3: -Chabertia sp Adult worms cause severe damage to the mucosa of the colon, with resulting congestion, ulceration, and small hemorrhages. Infected sheep are unthrifty; the feces are soft, contain much mucus, and may be streaked with blood.
