鞭虫成虫的扫描电镜观察

SCANNING ELECTRON MICROSCOPY OF ADULT TRICHURIS TRICHIURA

用扫描电镜观察人鞭虫成虫的体表超微结构，并与前人用光学显微镜所观察的结果作了比较，认为鞭虫体表展现了它的独特性。首次描述了头端口周的唇样结构，围绕着口孔环形排列着８个头孔和一对头感器。发现鞭虫体表散布着表皮孔，认为与排泄有关。对雄虫的交合刺鞘和交合刺的特征也进行了详细的描述。

The paper reports the result of the observation on the ultrastructure of the body surface of adult T. trichiura by scanning electron microscopy.Unique features of T.trichiura are described including the presence of labial shape structures at the periphery of mouth,eight cephalic pores and a pair of amphids around the mouth pore and vesicle shaped cuticular protuberances on the abdomen of T.trichiura .Cuticular pores were found scattering on the surface of T.trichiura .Detailed descriptions of male copulatory sheath and spicule were presented.
