传染性法氏囊病患鸡死亡机理研究

Study on Mechanism of Death of Chicken with Infectious Bursal Disease (IBD)

对传染性法氏囊病（IBD）发病过程中的微血栓形成做了动态检测，并观察了补液抗休克治疗对IBD发病过程的影响。结果发现：早期死亡鸡重要器官（肺、心和脑）中微血栓检出率比早期病（未死）鸡和晚期死亡鸡显著增高（P＜0．05）；补液抗休克治疗可显著降低IBD患鸡的晚期死亡（P＜0.001）。这说明重要器官的微血栓形成与IBD患鸡的早期死亡有关；而腹泻-脱水-低血容量性休克则是晚期死亡的主要原因。

Dealed with the mechanism of death of chicken with IBD by studying the mi-crothrombosis in chickens with IBD and the effect of fluid infusion on chickens with IBD.The results showed that there was a higher microthrombosis rate in vital organs (lung, heartand brain) of chickens died in the early stage of IBD than those of control. The fluid infusiontherapy could significantly decrease the mortality in late stage of IBD (P<0.001). Thisstudy indicated that the early death of chichens with IBD is related to the microthrombosis invital organs and the late death is mainly induced by diarrhoea-dehydration-hypovolemishock.
