Summary of OER 3.2 Antimicrobial Basics:Antimicrobials are drugs designed to kill or inhibit the growth of harmful microorganisms like bacteria, viruses, fungi, and parasites. These medications are vital in the treatment of infections, and they work based on the principle of selective toxicity—targeting the harmful organism without damaging the host's cells.
Antimicrobials are classified into two main types:
Bactericidal agents – these drugs kill microorganisms. Bacteriostatic agents – these inhibit the growth of microorganisms, allowing the immune system to eliminate them.The effectiveness of antimicrobials relies on proper dosing and duration of therapy. Incorrect use, such as taking doses that are too low or stopping the medication prematurely, can lead to antimicrobial resistance. This resistance occurs when microbes evolve mechanisms to survive the antimicrobial action, making infections harder to treat. Antimicrobial resistance is a significant public health concern, requiring careful prescription and use of these drugs.
Additionally, different classes of antimicrobials have varying mechanisms of action, such as disrupting the cell wall, interfering with protein synthesis, or inhibiting essential metabolic processes within the microorganism.
Multiple Choice Quiz Questions: What is the primary function of bactericidal agents? A) Inhibit the growth of microorganisms B) Strengthen the host's immune system C) Kill microorganisms D) Prevent microbial resistanceAnswer: C) Kill microorganisms
What is selective toxicity? A) The ability of a drug to harm only the pathogen, not the host B) A process that increases the growth of bacteria C) A condition in which the drug becomes toxic to the host cells D) The need for selective use of drugs in specific patient groupsAnswer: A) The ability of a drug to harm only the pathogen, not the host
Which of the following is a key factor in preventing antimicrobial resistance? A) Reducing the dosage of antimicrobials B) Stopping antibiotics when symptoms improve C) Completing the full course of prescribed antibiotics D) Avoiding the use of antibiotics altogetherAnswer: C) Completing the full course of prescribed antibiotics
How do bacteriostatic agents work? A) By killing bacteria directly B) By inhibiting bacterial growth and allowing the immune system to act C) By destroying the host’s immune cells D) By neutralizing the immune responseAnswer: B) By inhibiting bacterial growth and allowing the immune system to act
Which of the following is NOT a mechanism of action for antimicrobials? A) Disrupting the cell wall of the microorganism B) Enhancing the microorganism's metabolic processes C) Inhibiting protein synthesis in pathogens D) Blocking essential metabolic pathways in microorganismsAnswer: B) Enhancing the microorganism's metabolic processes
