细菌耐药性是细菌产生对抗菌药物不敏感的现象,是细菌在自身生存过程中的一种特殊表现形式。天然抗生素是细菌产生的代谢产物,用以抵御其他微生物,保护自身安全的化学物质。人类将细菌产生的这种物质制成抗菌药物用于杀灭致病微生物,微生物接触到抗菌药,也会通过改变代谢途径或制造出相应的灭活物质,使其避免被抗菌药物抑制或杀灭,形成耐药性。
Bacterial drug resistance is the phenomenon that bacteria produce insensitive to antibacterial drugs and is a special manifestation of bacteria in their own survival process. Natural antibiotics are metabolites produced by bacteria, to protect against other microorganisms, to protect their own safety chemicals. Human beings produce this kind of material made of antibiotics used to kill pathogenic microorganisms, microorganisms exposed to antibacterial drugs, but also by changing the metabolic pathways or create the corresponding inactivated substances, to avoid being inhibited or killed by antibiotics Off, the formation of resistance.
