抗生素使人类在与传染病的斗争中得以制服大部分致病微生物。但是,随着抗生素的广泛使用,微生物适应抗生素的能力越来越强,导致抗生素的疗效越来越低。连一些用于拯救危重病人、医学界称为“最后武器”的抗生素,在各种微生物面前也越来越显得无能为力。如万古霉素,80年代初在美国的使用量增加了100倍,但微生物对其抗药性增加了20倍,各国医学界认为,如果这种情况发展下去,在不久的将来诸如肺炎、肠炎等疾病也会因无药可医而致人于死地。 Antibiotics has made it possible for humans to subdue most of the causative microorganisms in the fight against infectious diseases. However, with the widespread use of antibiotics, the ability of microorganisms to adapt to antibiotics is becoming stronger and stronger, resulting in the decreasing efficacy of antibiotics. Even some antibiotics, which are used to rescue critically ill patients and are called “the last weapon” by the medical community, are becoming more and more powerless in the presence of various microorganisms. Such as vancomycin, the United States in the early 1980s increased the use of 100 times, but its resistance to microorganisms increased by 20 times, the medical profession in the world believes that if this situation continues in the near future such as pneumonia, enteritis, etc. Illness can kill people because they can not be cured.
