| 7 | Morphological diversity of cultured cold-active lytic bacteriophages isolated from the Napahai plateau wetland in China显示文摘Dear Editor,Viruses are the most abundant,diverse,and ubiquitous entities(approximately 1031)on Earth.They play major roles in horizontal gene transfer,the regulation of bacterial community structures,as well as nutrient and energy cycles of marine ecosystems(Danovaro et al.,2008).In particular,lytic bacteriophages(phages)can infect and kill bacteria without harming human or | Xiuling Ji Chunjing Zhang Anxiu Kuang Jiankai Li Yinshan Cui Kunhao Qin Lianbing Lin Benxu Cheng Qi Zhang Yunlin Wei | 2015 | Virologica Sinica2015，30，6： | 0 |
