前言七十年代以来,脊髓灰质炎(以下简称脊灰)在许多发达国家得到有效地控制,不少实验室对脊灰病毒的研究深入到分子生物学及病毒细微结构方面。这方面的成就将有助于对病毒本质的认识和对该疾病采取更加有效地控制手段,对其它动植物病毒也有借鉴作用。 Preface Since the 1970s, poliomyelitis (hereinafter referred to as polio) has been effectively controlled in many developed countries. Many laboratories have conducted deep research on poliovirus in molecular biology and virus microstructure. Achievements in this area will help to understand the nature of the virus and take a more effective control over the disease, as well as to learn from other plant and animal viruses.
