【发明专利】用于检测I型和II型非洲猪瘟病毒的多重荧光PCR引物探针组、方法和应用。
2020年，中国农业科学院哈尔滨兽医研究所国家非洲猪瘟专业实验室在开展非洲猪瘟流行病学监测及病原学研究中发现，我国部分省区出现了低致死率的非洲猪瘟基因II型自然变异流行株。目前，全球范围内非洲猪瘟病毒已鉴定出至少24种基因型。其中亚洲主要流行基因II型。时下，非洲猪瘟尚无商品化疫苗或有效治疗方法，早期诊断及感染猪群扑杀是防控主要策略。因此，开展流行病学监测及流行株的基因组变异、生物学表型及致病力研...

将鸡II型干扰素（ChIFNγ）基因和鸡传染性支气管炎病毒S1基因同时插入到鸡痘病毒转移载体中，构建含有这2个基因的鸡痘病毒转移载体pSY-ChIFNγS1。采用脂质体法将该质粒转染鸡痘病毒感染的鸡胚成纤维细胞（CEF），经过8轮蓝斑筛选，得到纯化的能够同时表达鸡II型干扰素和鸡传染性支气管炎病毒S1基因的重组鸡痘病毒rFPV-ChIFNγS1。rFPV-ChIFNγS1接种28日龄的SPF鸡1周...
约束指数的检验及一些理论考虑II.对选择指数的一些理论考虑
约束指数 检验
2007/12/7
摘要本文确定了最宜指数的范围，定义了超级选择的区间，并将其与无约束、约束及反向选择包括在最宜指数之内，从而证明了最宜指数是意义最广的选择指数，并使得在指数选择中，可以在一定范围内要求其中若干性状的进展取得特定的方向和大小。文中还简化了最宜指数的计算公式，并讨了各种选择指灵敏的应用问题。
