Concept explainers
To explain:
The genetic basis of acquired resistance to β-lactam antibiotics in Staphylococcus aureus. Design the laboratory experiments to reverse resistance to the β-lactam antibiotics. Can this experiment be applied “in the field” to promote deselection of antibiotic-resistant organisms?
Introduction:
The β-lactam antibiotics are the inhibitors of the synthesis of the bacterial cell wall. The mechanism and synthesis of the cell wall are unique in bacteria. The β-lactam antibiotics are the highly selective antibiotics and they target only on the bacterial cell wall and do not produce any toxic effect on the host. The β-lactam antibiotics, including penicillins and cephalosporins, are found to be the cell wall synthesis inhibitors. These antibiotics have a β-lactam ring in their structures.
