由于在水产养殖中抗菌药物被不合理地使用及致病微生物种类的变异,导致致病微生物耐药性呈逐年上升趋势,已经成为世界性的突出卫生问题。可以推测,随着各国制药工业的不断发展,新型抗菌药物也将会不断地推向市场,要准确地把控各类抗菌药物的作用特点及不同药物之间的差别将越来越困难。迄今为止,人们选择治疗疾病的药物主要还是以致病微生物药敏试验结果作为主要依据的。因此,药敏试验结果的正确与否直接关系到所选药物对疾病治疗的成败。目前,在国内药敏试验过程中还存在一些问题。如药敏试验方法不统一,没有完全标准化;从市场上购买的药 Due to the unreasonable use of antibacterial drugs in aquaculture and the variation of pathogenic microorganisms, the resistance of pathogenic microorganisms has been increasing year by year, which has become a prominent health problem worldwide. It can be speculated that with the continuous development of the pharmaceutical industry in various countries, new antibacterial drugs will also be introduced to the market. It is more and more difficult to accurately control the different types of antibacterial drugs and the differences between different drugs. So far, people choose to treat the disease mainly based on drug susceptibility testing of pathogenic microorganisms as the main basis. Therefore, the sensitivity test result is directly related to the success or failure of the selected drug treatment of the disease. At present, there are still some problems in the process of drug susceptibility testing in China. Such as susceptibility testing methods are not uniform, not completely standardized; purchased from the market medicine
