As showed above, we could draw the conclusion that H3 viruses could cause outbreaks or local epidemics in Shanghai for the immune of population to the new emerging antigenic drift was still unknown though there was strong immune barrier to the previous vaccine strain, H1 viruses also may caused epidemics as the population had a weak immune protection to the previous reference strains A/New Caledonia/20/99-like and part of the recent isolates were distingwishing from them and continued to evolute on the new reference strain, and H5N1 HPAI activities has expanded its geographical range thus increasing the size of the population at risk as the continuing emergence of human cases which give the virus an opportunity to evolve towards a fully transmissible pandemic strain. We should keep eyes on the human cases of avian influenza virus an its variation for the H5 isolates in Shanghai also has the possibility to infect human directly and the infection of H5, H9 viruses had previously occurred in the population especially in those contacting with animals.

综合上述分析结果，我们认为上海地区人群虽然对原有的H3亚型参考病毒株有较高的免疫保护，但H3亚型病毒HA已出现新的抗原漂移，人群现在对新变异株的保护水平尚未知，有可能在未来引起局限性暴发甚至地方性流行；人群对H1亚型流感病毒免疫保护水平低，同时H1亚型流感病毒株部分与原推荐疫苗株抗原性差别较大，并在现推荐疫苗株基础上继续变异，需警惕发生流行的可能性；H5N1亚型高致病性禽流感地域范围扩大，人间病例不断发生，存在演变成大流行株的威胁，上海市H5亚型禽流感病毒株存在跨宿主屏障感染人类的可能性，而且已发现人群尤其禽、畜类动物接触人群中存在H5、H9亚型流感病毒的既往感染，应警惕禽流感病毒的变异和人间病例的发生。

The morphological and cytopathological characters of the viruses were observed by electron microscopy The types of virus were identified with I-ELISA, DAS-ELISA, TAS-ELISA, RT-PCR and IC-PCR. The CP genes of the main viruses identified in this research were amplified by PCR, cloned into pGEM-T and sequenced. The pumpkin germplasm from Heilongjiang and Yunnan provinces was screened for resistance to the main viruses using friction and roots immersed inoculation.

应用电子显微镜负染法和超薄切片法观察病原粒体形态及细胞病理学特征；利用酶联免疫吸附测定法中的双抗体夹心ELISA、间接ELISA、三抗体夹心ELISA以及反转录聚合酶链式反应、免疫捕捉PCR方法鉴定了采集样品中的病毒种类；对被确定为南瓜主要病毒病原的外壳蛋白基因进行了PCR扩增，克隆到pGEM-T载体并进行测序；应用摩擦接种法和浸根接种法对云南、黑龙江省部分南瓜品系、品种进行了抗性筛选。

Those viruses, which can selectively replicate in and kill tumor cells, were called conditional replicative viruses or oncolytic viruses.

这种能选择性地在肿瘤细胞中复制，并进一步杀灭肿块，被称为条件性复制病毒或选择性复制病毒(conditional replicative viruses)，或溶瘤病毒。

The viral disease is one of the limiting factors for growing calla lilies and 16 viruses have been reported. Among these viruses, Dasheen mosaic virus, a member of the genus Potyvirus, is an important and widely spread virus which can infect at least 16 genera of aroid plants.

病毒性病害为目前海芋栽培上的主要限制因子之一，国内外曾有16种病毒被报导可感染海芋，其中芋头嵌纹病毒(Dasheen mosaic virus， DsMV)可危害16属以上的天南星科植物，其分布遍及世界各地，具有经济重要性。

Unlike human influenza viruses, swine viruses have different epizootiological patterns in different areas of world, which is enzootic and geographic dependence.

Avian flu viruses have demonstrated an ability to evolve to easily infect humans by exchanging genes with human viruses that subsequently permit them to recognise human receptor molecules and gain easy access to cells, typically in the human respiratory system.

禽流感病毒可通过与人类基因交换进化，进而能够识别人类细胞受体，获得进入细胞通道，尤其是人类呼吸通道，最终呈现易感染人的能力。
