【摘要】 南京地区某鸡场爆发群发性痛风,发病率达45 1%、死亡率达37 5%,且发病持续时间长。对该鸡场群发性痛风的病因学和临床病理学进行了比较细致的研究。结果表明该鸡场群发性痛风是由于病鸡患肾型传染性支气管炎和误喂高蛋白饲料共同作用引起的;组织学检查发现肾脏有典型的痛风石(tophus);发病鸡血浆尿酸浓度(780 17umol/L)与健康鸡(152 58umol/L)差异极显著(P<0 01),血浆无机磷与健康鸡差异显著(P<0 05),而血浆蛋白和钙与健康鸡差异不显著(P>0 05)。更多还原

【Abstract】 An outbreak of gout in a flock of caged layers is reported.The incidence rate and the mortality rate were as high as 451% and 375% respectively.The case lasted a long time.To investigate the pathogenesis of gout in the layers,etiology and clinical pathology research were performed.The results showed that the incidence of gout were caused by avian nephropathogenic infection bronchitis virus(IBV)and high protein feed.Tophus were found through the test of histology methods.The concentration of plasma uric acid(78017 umol/L)in episoded layers is extremely higher than concentration(15258 umol/L)of that in healthy layers.The difference of plasma inorganic phosphorus between episoded and healthy layers was distinct(P<005).The difference of plasma protein between the two kinds of layers is insignificant.更多还原
