A new mathematical descriptor was proposed based on 3D graphical representation. Using the method, we construct the phylogenetic trees of nine proteins of H7N9 influenza virus to analyze the originated source of H7N9. The results show that the evolution route of H7N9 avian influenza is from America through Europe to Asia. Furthermore, two samples collected from environment in Nanjing and Zhejiang and one sample collected from chicken are the sources of H7N9 influenza virus that infected human in China.
基于三维图形表示法提出了一种新的数学描述符。利用该方法,我们构建了H7N9流感病毒九种蛋白的系统发育树,以分析H7N9的起源。结果表明,H7N9禽流感的进化路线是从美洲经欧洲到亚洲。此外,从南京和浙江环境中采集的两个样本以及从鸡身上采集的一个样本是中国感染人类的H7N9流感病毒的来源。
