绵羊肺炎支原体对肺及肺外脏器影响的研究

Studies of Pathologyical Changes of Lung and Extrapulmonary Organs in Movipneumoniae Infection of Sheep

绵羊肺炎支原体(Movipneumoniae)是引起绵羊胸膜肺炎的病原体。一般认为绵羊肺炎支原体可引起羊的胸膜肺炎。通过病原培养和PCR检测,除了肺脏外,在其它脏器也能检测到支原体,特别是危重病羊在肺外其它脏器分离出支原体的几率更高。绵羊肺炎支原体除主要引起肺脏的病变外,还可以造成心、肝、脾、肾、脑、淋巴结的损害。肺脏不是肺炎支原体感染的唯一靶器官。

M ovipneumoniae is pathogen to cause Contagious ovine pleuropneumonia. Generally M ovipneurnoniae may cause sheep＇s peripneumonia. Besides lung, M ovipneumoniae may be detected in other internal organs with culture and PCR detection, the probability to separate M ovipneumoniae is higher form extra-lung organ of the serious illnesss sheep. Besides M ovipneumoniae can mainly cause the lung pathological change,it can cause lesion of heart, liver, spleen, kidney, brain, lymph node as well. Lung is not only one critical organ by M ovipneuraoniae infection.
