病原微生物实验室是指从事与病原微生物菌(毒)种、样本有关的研究、教学、检测、诊断等活动的实验室。根据病原微生物的传染性、感染后个体或者群体的危害程度,把病原微生物分为四类,其中第一类和第二类病原微生物称为高致病性病原微生物。根据实验室对病原微生物的生物安全防护水平,并依照实验室生物安全国家标准的规定,将实验室分为四级,其中三级和四级病原微生物实验室实验对象分别是危害程度为第一和第二类 The pathogenic microorganism laboratory refers to the laboratory engaged in research, teaching, testing, diagnosis and other activities related to the species and samples of the pathogenic microorganism (poison). According to the infectivity of pathogenic microorganisms, the degree of harm of individuals or groups after infection, the pathogenic microorganisms are divided into four categories, of which the first and second types of pathogenic microorganisms are called pathogenic high pathogenic microorganisms. According to the level of bio-safety protection of pathogenic microorganisms in the laboratory and in accordance with the national standards of laboratory bio-safety, the laboratories are divided into four levels, of which three levels and four levels of pathogenic micro-organisms laboratory subjects are the first And the second category
