Small worlds: an introduction to microbiology

In this course, which is suitable for those with an interest in biology, we will explore the hidden world of microbiology. The course, which will be based in the city centre laboratories of the Department of Biochemistry, is comprised of an integrated set of lectures and “wet” work and is intended to provide a solid and enjoyable introduction to the field. We will isolate and grow bacteria from a variety of different sources (including different body parts, as well as surfaces in the built and natural environment), identify them using selective media, look at how they move and communicate with one another (yes, bacteria do have a thriving social life….), investigate how antibiotics work and how resistance is spread, and also delve into the world of pathogens and "unculturables". We will also take a look at how we prevent bacterial growth, and identify some natural “predators” of bacteria…..some of these turned out to play a pretty major role in “the genetic revolution” in the second half of the twentieth century, and we will discuss why this is.

For each major “theoretical” concept that is introduced, we will try and carry out an informative experimental demonstration in parallel. Some experiments will be spread over the full five days of the course (for example, we will need to use PCR to solve a case of “food poisoning”…..) but most days will have a defined experimental theme. We will be getting "arty" with a palette of particularly colourful species, with a prize will be given for the best artwork. By the end of the course, you should be able to better appreciate the variety and importance of microbes (especially bacteria) in our world, with a particular emphasis on human health and wellbeing. We will also be touching on some state-of-the-art developments that are revolutionising the way in which we view microbes, their evolution, and their utility.
