1、Experiment III Examination of Fecal samples,粪便检查法,1.Place a drop of isotonic saline on a slide.2.Take a small piece of feces with a toothpick and stir it into the saline.3.Add a coverslip or not,and examine microscopically.,一、直接涂片法（Direct Smear）,二、饱和盐水浮卵法（Fecal Flotation）,Mix several grams(a teaspoo
2、nful)of feces with the flotation solution in a plastic cup.Strain the mixture through a cuprum strainer(60 mesh)into another plastic cup.Allow the flotation to stand for at least 5 minutes.Take a few drops of the surface of the solution with cuprum wire loop on a microscope slide,examine them under
3、the mecroscope with the 10 lens.,三、沉淀法（Fecal Sedimentation）,Mix about 100ml of water with about 10g of feces and place in a plastic cup.Strain the mixture through a cuprum strainer(60 mesh)into another cup.Allow mixture to sit for 10 minutes and then decant the supernatant.Add more water,mix,and rep
