2. Germ Theory or Theories?

About this Lecture

Lecture

In this module, we turn to look at Germ Theory in more detail. In doing this we see that there wasn’t just one Germ Theory of Disease but instead several. This was the result of many competing ideas about what germs were, how they caused disease, and what diseases they caused.

Course

In this course, Professor Michael Worboys (University of Manchester) explores the Germ Theory of Disease and the Bacteriological Revolution in the period 1860 to 1900. In the first module, we look at the ideas that existed about the causes and spread of infectious diseases before Germ Theory. We then turn to examine the theory itself. After this, we look at whether the Bacteriological Revolution can truly be called a revolution. The fourth module discusses Louis Pasteur’s work on vaccines. The fifth follows the career of Robert Koch and his creation of laboratory methods to investigate germs and their actions. In the final module, we review the key ideas of the course by showing how the understanding, prevention, and treatment of tuberculosis changed over the period.
