摘要
中华血吸虫和土耳其斯坦东毕吸虫结节变种分别收集于四川和黑龙江省 ,按常规电镜方法处理后 ,以日立 JSM- 80 0扫描电镜观察并摄片。观察显示中华血吸虫体表无结节 ,其雄性成虫体表结构近似于日本血吸虫等亚洲血吸虫 ,与文献描述的采集于泰国的中华血吸虫也无明显差异。观察同时表明土耳其斯坦东毕吸虫结节变种与程氏东毕吸虫基本无差别 ,二者的感觉球种类与土耳其斯坦东毕吸虫一致 ,但数目较后者为多。同时结合已发表的有关裂体属血吸虫 SEM研究结果 ,对裂体属血吸虫 SEM超微结构特点列表进行了比较。按照 Rollinson的分组方法 ,中华血吸虫属于无结节组 ,而东毕吸虫属于不带棘的有结节组。
Schistosoma sinensium and Orientobilharzia turkestanicum var. tuberculata were collected in Sichuan and Hei Longjiang Province respectively.The adult worms were prepared for routine scanning electron microscopy (SEM),and observed and photographed with Hitachi JSM 800. Our observations show that S. sinensium collected from Sichuan Province has no tuberculate on its surface and resembles in appearance to Schistosoma japonicum and other Asian schistosomes including S.sinensium found in Thailand.Our results indicate that there is no obvious difference in SEM structures of body surface between O.turkestanca var. tuberculata and O.cheni .The morphology of sensory bulbs of O.turkestanca var. tuberculata,O.cheni and O.turkestanca are identical,but the sensory bulbs of O.turkestanca is less than that of the other two species.The optical and SEM structural characters of related schistosome and Orientobilharzian species are compared in Table 1 and 2.
