抗生素(Antibiotics),又称做抗生性物质(Anti-biotic substance),是一种微生物(细菌、霉菌、酵母菌、放射状菌等)所分泌的化学物质,对于其他的微生物,具有专对性的遏制生长的作用。这种化学物质如果能够提制纯净,即成为有强效的抗菌药物。抗生素是近年来医学上一个重要的新发明,例如青霉素,即为其中著名的一种。最早创立抗生素学说的人,是细菌学的鼻祖巴斯德氏,他在1877年的时候,就设想利用微生物间的“残克现象”(Antagenism),来扑灭细菌性的传染病。微生物的残克现象最早是在土壤中发现的,在土壤中生存着有许多对人类无害的细菌,这些细菌对于和他们不同种的传
Antibiotics, also known as Anti-biotic substances, are chemicals secreted by microorganisms (bacteria, molds, yeasts, radial bacteria, etc.), and are specific to other microorganisms. Stop the effects of growth. If this chemical can be purified, it will become a potent antibacterial drug. Antibiotics are an important new invention in medicine in recent years. For example, penicillin is one of the famous ones. The earliest founder of the doctrine of antibiotics was Pasteur, the first ancestor of bacteriology. In 1877, he envisioned the use of inter-microbe “antagism” to extinguish bacterial infectious diseases. The phenomenon of residual micro-organisms of microorganisms was first discovered in the soil. There are many bacteria that are harmless to humans in the soil. These bacteria transmit different kinds of species to them.
