背景:近年来随着各大医院的曲霉菌类疾病病人人数的增加,对烟曲霉菌的研究日显重要.烟曲霉菌是一种分布广泛的真菌,其孢子体积很小,易于进入呼吸道,是一种常见的呼吸道过敏原,[1]易引起人、畜和禽类的肺曲霉病及其他疾病.目的:鉴于烟曲霉菌在医学上的重要性,本选题拟以烟曲霉菌为研究对象,通过采集自然环境标本,对烟曲霉菌进行培养、分离及鉴定,了解烟曲霉分布的基本信息.方法:通过采集不同来源的40株样本进行了培养,DNA提取,乳酸棉兰染色,10%KOH染色镜下观察,并经并经β-tubulin扩增确定曲霉菌,再进行CSP基因PCR扩增并进行测序.结果:经测序结果从中检测出9株烟曲霉菌.且潮湿环境的下腐生植物组织中烟曲霉菌分布高.结论:不同的环境对于烟曲霉菌的生长有直接的影响,烟曲霉菌在潮湿,易发酵的腐生植物和潮湿腐土土壤中更容易生长.

Background: in recent years, along with the increase of each big hospital Aspergillus diseasepatient population, important to the study of Aspergillus fumigatus is. Aspergillus fumigatusfungus is a widely distributed, the spores are very small in size, easy access to the respiratory tract, is a common respiratory allergens, [1] tends to cause people, livestock and poultrypulmonary aspergillosis and other diseases. Objective: in view of the importance of Aspergillus fumigatus in medicine, this thesis intends to Aspergillus fumigatus as the research object, through the acquisition of natural environmental samples, were cultured, isolated and identified on Aspergillus fumigatus, understand the basic information of Aspergillusdistribution of smoke. Methods: by collecting 40 strains samples were cultured, DNA extraction, lactic acid Medan staining, microscope observation 10%KOH staining, and by andby β -tubulin amplification identified Aspergillus, then CSP gene was amplified by PCR and sequenced. Results: the sequencing results of 9 strains of Aspergillus fumigatus from detection. Aspergillus fumigatus high distribution and humid environment saprophytic plant tissues. Conclusion: different environments have direct impact on the growth of Aspergillus fumigatus, Aspergillus fumigatus in wet, grow more easily fermented easily saprophytic plant and wet rot soil
