该菌在25℃培养基中培养为菌丝型,具有特征性的马内青霉菌帚状枝,能产生可溶性红色色素将整个培养基染呈红葡萄酒色.在37℃培养为酵母型,不产失色素。现已确定竹鼠是主要带菌动物,广西许多县份都有竹鼠,主要是银星竹鼠,也有少量中华竹鼠。解剖的43只竹鼠中,90％以上自然带马内青霉菌,而其他鼠类则未发现带菌。已证实竹鼠的胆汁、粪便和竹鼠洞穴内的无粪泥土中能分离出马内 The strain was cultured in 25 ℃ medium mycelium, characterized by Penicillium balanophora broom sticks, can produce soluble red pigment, the entire medium stained red wine color at 37 ℃ cultured yeast type, not Lost pigmentation. Bamboo has been identified as the main carrier animals, many counties in Guangxi have bamboo rats, mainly silver star bamboo rats, there are also a small amount of Chinese bamboo rat.
