Beta-lactamases are defined as enzymes that provide resistance to which type of antibiotics?

• A. Aminoglycosides
• B. Quinolones
• C. Beta-lactam antibiotics
• D. Tetracyclines

Answer: (C)

Beta-lactamases are enzymes produced by certain bacteria that provide resistance to beta-lactam antibiotics. These antibiotics include penicillins, cephalosporins, and other related compounds that have a characteristic beta-lactam ring in their molecular structure. When bacteria produce beta-lactamases, they can hydrolyze the beta-lactam ring, rendering the antibiotic ineffective. This mechanism of resistance is significant in clinical settings because it allows bacteria to survive and grow in the presence of antibiotics that would otherwise kill them or inhibit their growth. The importance of beta-lactamases in microbial resistance highlights the need for ongoing surveillance and development of new antibiotics and inhibitors that can overcome this resistance mechanism. Understanding this enzymatic action is crucial for treating bacterial infections effectively.
