| 摘 要： | 为制造疾病模型便于防治鸡肾型传支。将1日龄健康雏鸡70只分为A、B、C 3组(试验组、对照组和感染组),试验组人工接种IBV肾型毒株,感染组晚1 d放入试验组内混养,常规饲养管理,每日4次观察接毒后的临床症状,同时定期剖检病鸡和病死鸡,取多脏器固定于10%福尔马林液中、石蜡切片、HE染色,显微镜下观察组织病理学变化,按严重程度标+~++++后记录并标明曲线。结果表明,在整个试验过程中肾脏的病理变化最为严重并且持续时间较长,从第2天开始出现病变,并持续到第20天;其次是肺脏,病变出现在第5~16天;肝脏和肺脏的病变时间相同只是程度轻一些;心脏的病变出现在第6~13天。1 d后,感染组也出现相似的病理变化,说明此病的传染性很强。

| Abstract: | Disease model was built up for control of infectious bronchitis-nephritis(IBN).Seventy 1-day-old chicks were divided into three groups named A,B and C(experimental group,control group and infected group).IBN virus was inoculated artificially to experimental group,and one day post-inoculation chicks in infected group were put into experimental group.Clinical signs were observed 4 times each day under conventional management,sick and died chicks were autopsied periodically for pathological changes observed an... |
