Two spargana of 5 and 7 cm long were removed from the right-hand palm of 14-year-old girl at the General Hospital, Qalyubia, Egypt. Sparganum is the 2nd larval stage (pleurocercoid) of Diphyllobothrid cestode species develops in the vertebrate second intermediate host through ingestion of the crustacean first intermediate host.Dogs and cats are the final hosts get infected through predation of the second vertebrate host.Human attracts infection through drinking water contaminated with the infected crustacean host or consumption of the flesh of of vertebrate hosts such as frogs and reptilian species. The surgically removed specimens were parsitologically identified as a non-proliferative metacestodes of a spirometran species that then on molecular analysis proved to be . The present report has allocated Egypt on the world sparganosis map.Molecular characterization of 28 S rRNA of and correlation to other spp. from the Nile countries, particularly Ethiopia and Lake Victoria countries where the Nile waters originate, and from China were dealt with. Drinking of contaminated fresh water is the only proposed mode of infection in Egypt.
在埃及盖勒尤比省综合医院,从一名14岁女孩的右手掌取出了两条长度分别为5厘米和7厘米的裂头蚴。裂头蚴是双叶槽绦虫物种的第二幼虫阶段(裂头蚴),通过摄取甲壳类第一中间宿主在脊椎动物第二中间宿主体内发育。狗和猫是终末宿主,通过捕食第二脊椎动物宿主而感染。人类通过饮用受感染甲壳类宿主污染的水或食用青蛙和爬行动物等脊椎动物宿主的肉而感染。手术切除的标本经寄生虫学鉴定为一种 Spirometran 物种的非增殖性中绦期幼虫,随后经分子分析证实。本报告已将埃及标注在世界裂头蚴病地图上。处理了来自尼罗河国家,特别是尼罗河水发源地的埃塞俄比亚和维多利亚湖周边国家,以及来自中国的裂头蚴 28S rRNA 的分子特征及其与其他裂头蚴物种的相关性。在埃及,饮用受污染的淡水是唯一推测的感染途径。
