The peptidoglycan cell wall is an essential structure for the growth of most bacteria. However, many are capable of switching into a wall-deficient L-form state in which they are resistant to antibiotics that target cell wall synthesis under osmoprotective conditions, including host environments. L...
The recent development of novel antibacterial agents that target fatty acid synthesis and inhibit cell membrane formation is also discussed.J. WangH.O. SintimReference Module in Biomedical Sciences
The bacterial cell wall is a key target for antibiotic discovery; it is crucial for cell growth, and provides a physical protective barrier between the cell and its environment. Antibiotics that inhibit bacterial cell wall biosynthesis, such as penicillin and vancomycin, are extremely important in ...
WHO offers a new tool and sets a target to accelerate action against antimicrobial resistance The first statement "There is no harm in using the antibiotics that were given previously to a family member or friend for the same purpose."Most of the respondents correctly identified this first statem...
Such resistance may be developed through mutations involving genetic changes that result in inactivation of the drug (for example, β-lactamases), modification of previously essential biosynthetic pathways, or alteration of the target site (cell wall construction, folic acid biosynthesis, protein ...

There are several different classes of antibiotics that target specific cell envelope structures or enzymatic steps of cell wall synthesis (Figure 1). Figure 1 Schematic representation of the enzymatic steps involved in S. aureus cell wall synthesis and the targets of cell wall active antibiotics. ...
Multidrug-resistant bacteria, especially those that defy even last-resort antibiotics, are causing a global health crisis fuelled by antibiotic overuse and misuse as well as the lack of development of new antibiotics. Multidrug-resistant bacteria comprom
the target site (cell wall construction, folic acid biosynthesis, protein biosynthesis). Expulsion of the drug from the cell (efflux) is another mechanism bacteria can use to evade the action of antibiotics. These genetic changes can later spread through lateral gene transfer via transformation, ...
