The present study incorporated examination of the rumen of sheep infected with Paramphistomum SPP. On microscopic examination, it was found that, in the ruminal sections infected with mature Paramphistomum spp changes were observed only in the number of ruminal papille. But the sections infected with immature worms, hemorrhagic lesions and necrosis of the mucosal cells were observed. The mucosa was found thickened swollen, rugous and ulcerated. Thus it is concluded that the immature forms of paramphistomum spp caused more severe damage to the ruminal tissue whereas adult form inflicted mild tissue damage in the rumen of sheep.
