Most antimicrobial drugs currently in clinical use are antibacterial because the prokaryotic cell provides a greater variety of unique targets for selective toxicity, in comparison to fungi, parasites, and viruses. This book presents cutting-edge research on the current state of antimicrobial resistance. In understanding the mode of action of a disinfectant, it can be difficult to Now customize the name of a clipboard to store your clips. 1. In this Video the mechanism of Antibiotic resistance has been discussed in a detailed manner.You will clear the concepts of the following things :1.Transfer . Action mechanism: rupture of microbial cell membrane, decay of proton motive force, interference with biomolecules' activity.
