【摘要】 目的报道和观察云南地区结膜吸吮线虫成虫的显微形态结构特征,为云南地区鉴定结膜吸吮线虫提供参考依据。方法采集云南地区人感染的结膜吸吮线虫,用显微镜观察虫体形态结构特征。结果肉眼观察虫体成乳白色、呈线状,雄虫尾部有弯曲状,雌虫尾部尖直,雌虫相比雄虫略长。显微镜下虫体体表角皮皱褶见明显环纹,环纹上下排列呈锯齿状;头端钝圆,无唇瓣,口囊较大,略呈碗形或圆孔形,可见食管;雌虫虫体两端较细,肛门在尾部腹面,阴门位置在虫体前端食道与肠连接处的前方,虫体内充满大量虫卵和幼虫;雄虫虫体尾部向腹面卷曲,有一对交合刺和乳突结构。结论云南人源结膜吸吮线虫与其它地区虫体形态相似。更多还原

【Abstract】 Objective To report one case of thelaziasis and observe the microscopic morphology of the adult of Thelaziacallipaeda, so as to provide the reference for identification of T. callipaeda in Yunnan Province. Methods T. callipaeda wascollected from a patient in Yunnan Province and the morphology of the adult of T. callipaeda was observed with a microscope.Results By eye observing, T. callipaeda adult body was milky white and linear, the female worm body was longer than maleworm. The tail of male worm was bent and the tail of female worm was straight. Under the microscope, the adult body wascovered with a serrated cuticle with striation. The head of worm was blunt round, the mouth had no lip, but the oral capsule waslarger and presented as a bowl or round hole with the visible esophagus. Both ends of the female worm were thinner, the analwas located in the ventral tail and the vulva was located in the front of the junction of esophagus and intestine, and the wombwas full of a large number of eggs and larvae. The male worm tail curved to the venter, and had a pair of copulatory spicules andpapillae. Conclusion The morphology of T. callipaeda from a patient in Yunnan Province is similar to that of T. callipaeda inother areas.更多还原
