To meet the medical need for next-generation antibiotics, a more rational approach to antibiotic development is clearly needed.Opening with a general introduction about antimicrobial drugs, their targets and the problem of antibiotic resistance, this reference systematically covers currently known antibiotic classes, their molecular mechanisms and the targets on which they act.
