摘    要:目的研究光镜下各期人芽囊原虫(Blastocystishominis,B.h)形态,以进一步研究其生活史及致病性,并为临床检验提供形态依据。方法使用洛克氏液-鸡蛋-血清培养基,对腹泻患者粪便的B.h进行体外连续培养,经碘液染色及铁苏木素染色,在光镜下研究其各期形态、结构。结果通过形态学研究观察到空泡型、颗粒型、阿米巴型及包囊型以及各型之间的相互转化。结论B.h形态多样,临床多见空泡型和颗粒型。空泡型可成囊。

关 键 词:人芽囊原虫  腹泻  培养基  光镜形态

Abstract:Objective To study morphology of different stage Blastocystis haminis (B.h) for establishing a base in the research of life cycle and pathogenicity of B. h and providing information for clinical laboratory. Methods B. h from diar-rheal patients was continuously cultured in LES medium, and morphology of B.h was studied with iodine and iron hematoxylin staining under light microscope. Results The vacuolar, granular, amoeboid and cyst forms of B. h and transformation among the forms were observed microscopically. Conclusion Among different forms, the vacuolar and granular forms were often seen clinically and the vacuolar form can transform to cysts.
Keywords:Blastocystis hominis   diarrhea   medium   morphology
