3 labs examine
3.1 carry carefully with cusp forceps take the larger larval put oneself in another's position inside lung blood capillary, glycerine is transparent after the law appears his in the open to manage, its mouth, tail end and genital structure observe below microscope, appraisal is ascarid larva.
3.2 be the same as egg of group of bug of pig excrement and urine to examine to adopt the excrement and urine that is the same as brood of 2 head pigs to make bug egg computation respectively, the method uses Si Tao method. Excrement and urine of two pigs 1g is medium as a result, ascarid egg number is in 3000 above.
