医学上的感染,是指病原微生物侵入人体所引起的局部组织和全身性炎症反应。因此,要应付感染性疾病,首先得从了解微生物开始。其实,微生物和人类并不陌生。它们几乎占据了我们身体的各个表面。某些微生物和人类的关系甚至可以说是“相依为命”。然而,令人脸红的是,我们对微生物的认识却几近苍白。 Medical infection, refers to the pathogenic microorganisms invade the body caused by local tissue and systemic inflammatory response. Therefore, to deal with infectious diseases, we must start by understanding the microorganisms. In fact, microorganisms and humans are no strangers. They occupy almost every surface of our body. The relationship between some microbes and humans can even be called “dependent”. However, it is blushing that our knowledge of microbes is almost pale.
