目前对人毛滴虫的病原学研究的报道较少,特别是在光镜下观察的形态结构仍有不完善之处。为此,我们对人毛滴虫的表面结构进行了扫描电镜观察,以便进一步探讨本虫的致病力和对其防治措施提供形态学依据。 材料和方法 取感染人毛滴虫的腹泻病人粪便,放在羊血水培养基内,即洛克氏液加入羊血水内(4:1),置37℃ At present, there are few reports of etiological studies on human trichomoniasis, especially the morphological structures observed under light microscope are still imperfect. To this end, we observed the surface structure of human trichomoniasis by scanning electron microscopy in order to further explore the virulence of this insect and provide a morphological basis for its prevention and treatment measures. Materials and Methods Stool from diarrhea patients infected with Trichomonas vaginalis was placed in goat blood water medium (Ractobacillus johnsonii) into sheep’s blood (4: 1)
