Bacteria, Antibiotics and Resistance
In this first part of the course, you will learn about the problem of antibiotic resistance, bacteria, bacterial cell structure, how antibiotics work and how bacteria can become resistant.
Deaths due to antimicrobial resistance are estimated to reach 10 million by 2050.
These first videos introduces you to the problem of antibiotic resistance and begins to introduce you to bacteria.
A bacterial cell about to divide.
The bacterial cell structure is described and we begin to understand how they grow and divide. This knowledge is important to understand how bacteria can be inhibited by antibiotics.
Testing bacteria for antibiotic resistance
In this lecture you will learn how the different types of antibiotics work to kill or stop the growth of bacteria.
Selection for Resistant Bacteria.
Bacteria can become resistant to antibiotics by several mechanisms. We’ll describe first the different types of resistance that can occur and then how resistance arises and spreads between bacteria.
Creating new antibiotics requires a good knowledge of chemistry as well as biology so that we can either design new antibiotics or alter natural antibiotics to improve their effectiveness.
