Answer:
The correct answer is infections caused by bacteria.
Explanation:
A drug, which particularly targets and destroys peptidoglycan is known as the antibacterial drugs. Many categories of antibacterial drugs prevent the synthesis of peptidoglycan, which is, an essential component of the bacterial cell wall that helps it to survive within the human host. This degradation of peptidoglycan makes the bacterial cell more vulnerable to osmotic lysis.
Of the many antibacterial drugs, penicillin was the first one to get discovered, and the substance comes under the category of beta-lactams. Apart from penicillin other compounds that come under the category of beta-lactams are cephalosporins, carbapenems, monobactams, and others that are featured by the existence of a beta-lactam ring within the molecule.
