从三个竹鼠洞采集的泥土标本中分离出马内青霉菌,证明竹鼠体内携带的马内青霉菌可污染环境,并能在泥土中生长。估计孢子可随着泥土尘埃飞扬传播,而造成呼吸道感染。实验采用Larsh介绍的泥土混悬液作为接种液,并用生物过滤法从诸多杂菌的泥土中分离出马内青霉菌. Penicillium marneffei was isolated from soil specimens collected from three rhizomes of bamboo and bamboo, demonstrating that Penicillium marneffei carried in the bamboo carp could pollute the environment and grow in the soil. It is estimated spores can spread with the dust of the earth, causing respiratory infections. In this study, the soil suspension introduced by Larsh was used as the inoculum, and Penicillium marneffei was isolated from the soil of many species by biofiltration.
