Abstract: “Cross resistance” (CR) is a phenomenon in which the bacteria have evolved to resist different types of antimicrobial molecules with similar structure or mechanisms of action, while "collateral sensitivity" (CS) can be defined as a situation where the bacteria have developed resistance to one antibiotic showed increased susceptibility to another antibiotic. The evolution of bacterial resistance is a complicated process that can either lead to cross resistance or collateral sensitivity under the selection pressure from antibiotics. Recently, CS has been proposed as a promising alternative approach to counteract the rising problem of antibiotic resistance. To better understand the mechanisms by which bacterial collateral sensitivity has been evolved and the application prospect of CS, in this review, we summarized our current knowledges on key factors influencing the bacterial collateral sensitivity and the regularities of CS. We also discuss directions and challenges for developing CS-informed treatment strategies.

Key words: bacteria resistance, collateral sensitivity, drug revolution resistance
