Bacterial stress response, physiological metabolism and antimicrobial tolerance and the control strategies

Abstract:

Overuse of antibiotics in medical care and animal husbandry has led to the development of bacterial antimicrobial resistance, causing increasingly more health concern. In addition to genetic mutations and the formation of resistance, the various stresses bacteria encountered in the natural environment trigger their stress responses, which not only protect them from these stresses, but also change their tolerance to antimicrobials. The emergence of antimicrobial tolerance will inevitably affect the physiological metabolism of bacteria. However, bacteria can restore their sensitivity to drugs by regulating their own metabolism. This article reviews recent studies on the relationship between bacterial stress responses or the physiological metabolism and antimicrobial tolerance, intending to take more effective measures to control the occurrence and spread of antimicrobial resistance.
