title: [Study on morphology of Blastocystis hominis in culture and from diarrhea patients].
abstract: OBJECTIVE
  To study morphology of different stage Blastocystis hominis (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 diarrheal 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.
  
  
  CONCLUSIONS
  Among different forms, the vacuolar and granular forms were often seen clinically and the vacuolar form can transform to cysts.
