An experiment was designed to excite student's interest and culture the comprehensive ability. The halitosis-correlated bacterias in different shapes in saliva were isolated. The halitosis-correlated bacterias as vaccine were injected in layers together with Freund adjuvant. The egg yolk antibody (IgY) was identified after extraction and purification. It was expected that the series of multiple subject experiments for improving the learning efficiency and the cultivation of students should be improved.%为了激发学生对实验的兴趣,培养学生的综合能力,设计了一个综合性实验.该实验首先分离和培养了口臭菌,并对其进行形态观察,然后制备成疫苗,通过免疫、分离提取和鉴定,获得了卵黄抗体IgY.该实验涉及多个学科的多种类型实验,以期提高学生学习的时效性及有利于对学生综合能力的培养.
