抗生素在控制细菌感染和许多传染病的治疗中起了积极作用。除抗生素外,一些化学合成药物如磺胺类,呋喃类、喹诺酮类、咪唑类和甲硝哒唑等,对某些细菌或真菌亦具有强大的抗菌活性,这些药物与抗生素相比,化学结构较简单,可通过化学合成获得,不消耗粮食。随着化学合成工业的发展,品种日益增 Antibiotics play a positive role in the control of bacterial infections and the treatment of many infectious diseases. In addition to antibiotics, some chemosynthetic drugs such as sulfonamides, furans, quinolones, imidazoles and metronidazole also have strong antibacterial activity against certain bacteria or fungi. Compared with antibiotics, these drugs have a more chemical structure Simple, obtainable by chemical synthesis without consuming food. With the development of chemical synthesis industry, the variety is increasing day by day
