怡乐村并殖吸虫后尾蚴在扫描电镜下,体表密布单生体棘,其形状与大小在各部位略有差异。虫体腹侧前中部体棘中央有一条纵行隆起线为其特征。口、腹吸盘上除具短小的体棘外,均具有两圈感觉乳突,口吸盘上外圈为12个,内圈为6个;腹吸盘上内外圈各为6个。腹吸盘周围体壁上则无感觉乳突。感觉乳突除散在于体表外,在腹侧前半部外侧,各有8～10个呈对称性排列成行。 Yile village Paragonimus cercariae after scanning electron microscopy, surface dense single spine, its shape and size of the site slightly different. The ventral abdominal body before the central spine has a vertical line uplift its main feature. In addition to having a small body spine, the mouth and abdominal suction cups both had two loops of feeling mastoid. There were 12 outer rings on the mouth suction cups and 6 inner rings, and 6 on the inner and outer belly. Abdominal suction around the abdominal wall without feeling papillae.
