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

4、eat the sedimentation procedure until the supernatant will be very clear.Stir remaining mixture and place a few drops on a microscope slide,examine them under the mecroscope with the 10 lens.,家禽体内的寄生虫卵1.鸡蛔虫卵2.鸡异刺线虫卵3.类圆线虫卵4.孟氏眼线虫卵5.旋华首线虫卵6.四棱线虫卵7.鹅裂口线虫卵8.毛细线虫卵9.鸭束首线虫卵10.比翼线虫卵11.卷棘口吸虫卵12.嗜眼吸虫卵13.前殖吸虫
