Practice Question

What is the therapeutic effect of a bactericidal antibiotic?

Answer Choices:

Correct Answer:

It directly kills bacteria, leading to eradication of the infection

Rationale:

💎Bactericidal antibiotics act by destroying bacterial cell walls or interfering with essential bacterial enzymes, resulting in bacterial death.

💎This mechanism is especially important in life-threatening infections or in immunocompromised patients, whose immune systems may not effectively destroy bacteria.

💎Examples include penicillins, cephalosporins, and aminoglycosides.

💎The therapeutic goal is to eliminate the pathogen entirely, stopping infection progression.

💎Unlike bacteriostatic agents, bactericidal drugs cause irreversible bacterial destruction, not just growth inhibition.
