Microbes – friend or foe?

Introduction

This course looks at two aspects of microbes. The first section covers the way that bacteria cause disease and how they can become resistant to the antibiotics used to treat them. The second covers the important role that microbes play in treating sewage to purify the water so that it can be returned to rivers or to the sea.
