Under condition of captive breeding, the occurrence of diseases has also become more and more frequent in bamboo rats. In this paper, the results of mor- phological and biochemical studies showed that the cultural and biochemical charac- teristics of isolated strains are basically the same, and they all have strong pathogenicities to bamboo rats. The disease was diagnosed to be caused by the mixed infection of Escherichia coil and Arthrinium saccharico/a, and it was controlled by corresponding measures.展开更多
