肠道病毒是一大群寄居于人消化道细胞内增殖的病毒。 特点: 1.病毒体呈球形,衣壳为20面体立体对称,无包膜。 2.核心为单股正链RNA,具有感染性。 3.在宿主细胞浆内增殖,有较强的杀细胞作用。 4.耐乙醚和酸,较耐热

由于黄病毒属的大多数病毒可以通过吸血昆 虫为媒介引起人类的多种疾病,曾经被称为虫媒 病毒(arbovirus或节肢动物媒介病毒 (arthropod borne virus),分属于14个病毒科, 其中主要的有披膜病毒科、黄病毒科、布尼雅病 毒科。 这类病毒结构相似,大多数是20面体立体对 称的有包膜的RNA病毒

Questions list for Bacteria I 1. Draw the phylogenetic tree of the major lineages of Bacteria based on 16S ribosomal RNA Sequence comparisons. 2. How many groups of purple bacteria you have learned?

Notes LECTURE Biochemistry 9.17.04 ATP is both a unit of energy currency in a cell and a building block of RNA. Why? It is believed that early in evolution there were very few molecules around. Many key pathways are ancient, and trace their origin to the early stages of evolution of life on Earth. Incidentally, such pathways are usually highly conserved in modern organisms. This is probably because once

本病是由BVDV引起的一种牛的急性和慢性传染病，其特征为粘膜发炎、糜烂、坏死和腹泻。 黄病毒科、瘟病毒属的成员，单股RNA，有囊膜，35-55nm。 本病毒能在牛肾、睾丸、鼻甲、气管等细胞增殖传代。 与猪瘟病毒、羊边界病毒同属、有密切抗原关系
