摘要
将 4 0只 1日龄雅康蛋用公雏饲喂至 30日龄 ,随机分为感染组和对照组 ,感染组鸡用传染性法氏囊野毒进行点眼、滴鼻和肌注 ,并于感染后 4 8h、72h、96h剖杀 ,取非免疫器官按常规石蜡切片 ,H·E染色 ,光镜观察。结果表明 :雏鸡感染传染性法氏囊病毒后 ,非免疫器官均发生了不同程度的病理变化 ,且随感染时间的延长 ,其病变程度越严重 ,其中以肝、肾的实质细胞变性、坏死较为严重 。
one-day-old male Yakang chickens were raised under pathogens-free condition,and then divided randomly into infected and control group at 30 days old. The infected group chickens were given virulent strain of Infectious bursal disease virus (IBDV) by eye-drop,nose-drop,muscle-injection and killed 48,72,96 h after the challeng respectively.Non-immune organs of infected and control chickens were sampled,fixed with Bouins,sliced with wax,stained with hemtoxylin eosin dye(H·E) and were observed microscopically. The results showed that the non-immune organs of infected chickens showed progressive pathological lesion,Such as degeneration and necrosis of parenchaemal cells of live and kidney,medial pooliferosation and inflamatory vascular reaction.
