摘要
流感可以跨种属传播,通过了解地方性低致病禽流感H9N2亚型病毒感染不同种属动物后的血液变化情况,可为研究禽流感病毒的致病机制提供参考依据。选用52d黑羽乌骨鸡24只,52d樱桃谷鸭24只,6周龄~8周龄昆明系小鼠24只分成3组,攻毒前作为0d空白对照,鸡、鸭和小鼠采用静脉注射感染H9N2亚型流感病毒,分别在感染前(0d)、感染后3d、6d、9d采样,用PE-6800VET三分类动物血细胞分析仪测定血液常规指标。通过对不同种类白细胞和血小板数量变化的分析,结果表明,低致病性禽流感病毒H9N2可以跨种属感染,鸭炎性反应最小,小鼠炎性反应最严重。
Avian influenza virus can spread across species.After the local low pathogenic avian influenza subtype H9N2 virus infecting different species of animals,the changes of their blood can provide a reference for the pathogenic mechanism of avian influenza virus.Twenty four fifty-two days old dark feather silky chickens,twenty four fifty-two days old cherry valley ducks and twenty four six to eight weeks old Kunming mice were divided into three groups.Before injecting the virus as 0 day blank control,chickens,ducks and mice were infected with the H9N2 subtype influenza virus by intravenous injection.The blood was collected and hematologic indexes were measured by the PE-6800 VET animal blood cell analyzer 0 day before infection,3 days,6 days and 9 days after infection.The results showed that low pathogenic avian influenza virus H9N2 can spread across the species.Ducks inflammatory response was minimal and the inflammatory response of mice was most serious in the animals.
