title: Studies of pathogenicity of the digenetic trematode Ganeo tigrinum (Mehra et Negi) for the stomach of Rana tigrina (Daudin).
abstract: Ganeo tigrinum (Mehra et Negi) was seen to be attached to the stomach wall of Rana tigrina (Daudin) by suckers drawing out mucosal plugs. The tissues lodged inside the suckers were desquamated, ulcerated and necrosed. Encapsulated flukes were seen in the submucosa. The stomach wall was completely dissolved at the site of entry of the fluke, while adjacent tissues were compressed. The gastric mucosa was mechanically compressed by the fluke. Oedema, cellular infiltrate, dilated blood vessels and congested blood capillaries were seen in the infected stomach. PAS positive and alcian blue negative mucoid substances were present in large amounts in the lumen and in small amounts in the mucosal epithelial cells of the fluke-infected stomach.
