中华鳖白底板病和红底板病病毒及细菌的致病性

STUDY ON THE PATHOGENESIS OF VIRUS AND BACTERIA IN WHITE AND RED ABDOMINAL SHELL DISEASE OF TRIONYX SINENSIS

利用含类呼肠孤病毒和类腺病毒 的患白底板病和红底板病 病鳖组织匀浆过滤液及从病鳖中分离的致病性嗜水气单胞菌， 进行病毒和细菌的相继 人工感染试验， 复制出典型的鳖红底板病和白底板病病症。研究发现， 细菌是红底板病的主要病原， 病毒是白底板病的主要病原，而病毒的感染不致死鳖， 细菌的继发感染是鳖最终死亡的因素。

By electron microscopy,one reovirus-like and one adenovirus-like virus was observed in infected T.sinensis.Initial study by successive infection of T.sinensis with the virus and bacteria caused the pathogenecity characteristic of the red and white abdominal shell disease.The findings indicate that bacteria were the main pathogens of the red abdominal shell disease and the virus was the main pathogens for the white abdominal shell disease.Virus infection in T.sinensis is not a lethal but subsequent infections with bacteria cause mortality.
