Haemonchus contortus Infection and Associated Pathological Changes in a Goat (Capra hircus)

Abstract

The animal had emaciated body, pale mucous membranes with the history of anorexia and loss of body weight.

Fecal sample collected for microscopic examination revealed 1150 egg per gram indicating severe parasitic infestation.
