蛲虫卵形态的再探讨

Rediscussion on the morphology of Enterobius vermicularis eggs

目的探讨光镜下蛲虫卵所呈现的不同形态特征,为蛲虫病的临床诊断和教学提供依据。方法取实验室保存的蛲虫卵于在光镜下观察形态,统计各种形态蛲虫卵的比率。结果蛲虫卵形态在光镜下呈多样性,其中以近似不等边三角形最多,以长椭圆形次之,以圆形及卵圆形较少。结论蛲虫卵在普通光镜下的形态具多样性,在临床诊断和实验教学中应结合其多态性作综合考虑,避免以偏概全,造成误诊或导致学员误解。

Objective To investigate the morphology ofE. vermicularis eggs under fight microscope, and to discuss the polymorphism of E. vermicularis eggs, in order to accumulate further details for clinical diagnosis and teaching. Methods To observe the morphology of E. vermicularis egg and calculate the proportion of different shape of eggs under light microscope. Results The morphology of E. vermicularis eggs showed polymorphism under fight microscope, more than one-third showed triangle-like, followed the long-ellipse shape which was a litde less than one-third, and then the round or oval shape. Conclusion The morphology of E. vermicularis eggs is polymorphism under light microscopy, we should take a notice in diagnosis and teaching .
