Antimicrobial Stewardship (Bitesize)
Antimicrobial Resistance (AMR) happens when microbes (bacteria, viruses, fungi and parasites) change over time and stop responding to medicines; this causes infections that are more difficult to treat and increases the risk of disease spreading, severe illness and death. This module looks at what a microbe is and explains how microbes can both help and harm the human body.

Learning Outcomes
What you'll learn
- Define what a microbe is and explain how they can both help and harm the human body
- Identify the four types of antimicrobial medications that are commonly used
- Explain how microbes become resistant to medication and what can be done to slow this process down
- Recognise the impact of antimicrobial resistance and why this is of worldwide concern
- Explain why some infections do not need treatment with antimicrobial medication

Frequently Asked Questions
Antimicrobial stewardship promotes the responsible use of antimicrobial medicines to ensure they are used appropriately, safely and only when needed, helping reduce antimicrobial resistance.
Antimicrobials are medicines used to prevent or treat infections caused by microorganisms. They include antibiotics, antivirals, antifungals and antiparasitic medicines.
Antimicrobial resistance occurs when microorganisms change and no longer respond effectively to medicines used to treat them, making infections harder to manage.
Resistance can make infections more difficult to treat, increase illness and complications, and reduce the effectiveness of medicines used to prevent and treat infections.
Some infections, such as many viral infections, do not respond to antibiotics. Using antimicrobials when they are not needed can contribute to antimicrobial resistance.
