实验室的传染源是指检疫人员在检疫抽样、疫情调查、现场考查学习过程中,获取的罹带疫情的植物组织、植物种子或未定型的标本携回实验室,作研究用的材料,而这些材料大都是检疫对象和危险性病、虫携带者,经过室内分离、培养(饲养),易形成新的强有力的传染源。对检疫对象的引进试验或隔离试种,一般都会引起重视,需经省一级或中央级检疫部门审批同意后方可实施,防范措施是严密的。而在我们平时的常规检疫检验中,从局部疫区、现场采回的病、虫植物组织活体带回实验室,经分离培养过程后,其剩余的病菌培养 Laboratory sources of infection refers to quarantine officers in the quarantine sampling, epidemic investigation, on-site examination of the learning process, obtained with the outbreak of plant tissues, plant seeds or undetermined specimens back to the laboratory for research materials, and Most of these materials are quarantine objects and dangerous diseases, insect carriers, after indoor separation, culture (feeding), easy to form a new source of strong infection. The introduction of quarantine objects or isolation of the test species will generally receive the attention of the provincial level or quarantine departments need to be approved before implementation, preventive measures are tight. In our usual routine quarantine and inspection, the disease and insect tissues collected from the local epidemic area and site were brought back to the laboratory for living organism. After the isolation and culture process, the remaining pathogen culture
