| 摘 要： | 鸡贫血病毒是鸡传染性贫血病的病原。世界各国不同年龄的肉用型和蛋用型鸡均可发病 ,也可感染SPF鸡。鸡贫血病毒无囊膜、二十面体、单链环形DNA病毒 ,基因组长度为 2 3kb。既可垂直传播 ,也可水平传播。引起鸡CAV综合症 :表现为死亡率增加、造血器官骨髓萎缩、皮下和肌肉内出血、淋巴系统萎缩引起免疫抑制、皮肤损伤等。CAV只有一种血清型。临床发病及亚临床症状皆造成严重的经济损失

| Abstract: | Chicken infectious anaemia disease is caused by chicken anaemia virus(CAV).It seems to have a worldwide distribution both in meat-type and egg-laying chickens of all ages,as well as infects SPF chickens.CAV is non-enveloped,icosahedral DNA virus with a single-stranded,circular genome of 2.3kb.It transmits both vertically and horizontally.It causes a syndrome in chicken characterized by increased mortality,astrophy of the haematopoietic tissues in the born marrow,subcutaneous and intramuscular haemorrhages,immunosuppression as a result of the lymphoid system,skin lesions et al.Only one serotype of CAV has been found in the world.Both clinical and subclinical diseases lead to severely economic losses. |
