简介：流行性感冒A病毒(H1N1)2009，一个新猪起源流行性感冒A病毒，世界范围地被散布了并且引起了大公共害怕。高产量的transcriptomics和proteomics方法现在正在被使用识别H1N1和H1N1主人相互作用。这篇文章在H1N1诊断，处理，和H1N1病毒主人相互作用考察最近的transcriptomics和proteomics研究，到为进一步理解感染机制并且控制H1N1传播提供一些帮助。

简介：用定序技术的16SrDNA基因，entomopatho遗传因子的线虫(杀虫剂的一种)的非共生的细菌的三不同的种(Steinernemasp。并且Heterorhabditissp)从感染的昆虫死尸被孤立并且识别{街郎mellonella幼虫)在48小时的柱子感染以后。顺序类似分析表明紧张SRK3，SRK4和SRK5分别地属于Ochrobactrumcytisi，Schineria幼虫和Ochrobactrumanthropi。isolatesO。anthropi和S。幼虫被发现分别地，而，与Heterorhabditisindica紧张BDU-17和Yer-136被联系O。cytisi与Steinernemasiamkayai紧张BDU-87被联系。Phenotypically，时间的杀虫剂的一种细菌是相当与共生杀虫剂的一种细菌(Photorhabdus和Xenorhabdus类)有关。紧张SRK3和SRK5phylogeographically类似于几非共生者并且污染了在德国(LMG3311T)和中国(X-14)孤立的杀虫剂的一种细菌，当紧张SRK4与S的isolates相同时。从在匈牙利的Wohlfahrtiamagnifica的幼虫(Ll/57，Ll/58，Ll/68和L2/11)。结果被RNA第二等的结构和排列序列的最小的精力计算进一步证实。这研究建议这些线虫的非共生者phylogeographically由于阶段变化在某程度被分叉。因此，这些紧张不是主人依赖者，但是环境特定孤立。
