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.

摘要

发现条纹盖罩吸虫(Mehra和Negi)通过吸盘附着在泽蛙(Daudin)的胃壁上,吸盘吸出黏膜栓。吸盘内的组织出现脱落、溃疡和坏死。在黏膜下层可见被包囊的吸虫。吸虫进入部位的胃壁完全溶解,而相邻组织受到压迫。吸虫对胃黏膜造成机械性压迫。在受感染的胃中可见水肿、细胞浸润、血管扩张和毛细血管充血。在吸虫感染的胃腔中大量存在PAS阳性和阿尔辛蓝阴性的黏液物质,而在黏膜上皮细胞中含量较少。
