Abstract

The large stomach worm, Haemonchus contortus is a highly pathogenic nematode parasite of sheep (Ovis aries) and goats (Capra hircus). It sucks blood and causes acute disease, anaemia and severe economic losses due to morbidity and mortality. This paper compares characteristics of surface cuticular ridges (synlophe) and morphometrics of total body length, cervical papillae, spicules, barbs, gubernaculum and vulvar flap morphology of H. contortus recovered in the two hosts from the States of Perak and Kelantan, Peninsular Malaysia. The morphological variation in H. contortus samples recovered from the two hosts in Kelantan was found to be higher than from Perak. A discriminant function, based on three measurements of the spicule, confirmed the identity of male worms in the two hosts as belonging to the same species H. contortus.
