噬菌体是以细菌为宿主的特殊病毒,具有宿主的特异性,每一种细菌都可以是多种噬菌体的宿主。噬菌过程可分为三个不同阶段即吸附阶段、复制阶段和裂解阶段。噬菌过程受噬菌体宿主的内外环境多方面因素的影响。根据有细菌的地方就有噬菌体存在理论,噬菌体广泛地用于鼠疫的细菌学诊断,对疫源地调查具有重要意义。我们作了西藏1987年从自然界分离的1株鼠疫噬菌体对温度的选择实验,结果如下。
Bacteriophages are special viruses that are based on bacteria and have host specificity. Each bacterium can be a host of many bacteriophages. Phage can be divided into three different stages of adsorption, replication and pyrolysis stages. The phagocytosis process is affected by various factors inside and outside the phage host. Bacteriophage exists according to the bacteriological theory. Bacteriophages are widely used in the bacteriology diagnosis of plague and are of great significance to the investigation of the epidemic area. We made a Tibet in 1987 from nature isolated from a plague phage temperature selection experiments, the results are as follows.
