What is a microbe and what have they ever done for us? From Black Death to Cholera, and Syphilis to Typhoid, microbes have been responsible for some of the world’s most devastating diseases. But they have also provided the human race with the technological advances of genetic engineering and nitrogen fixation, the vision of life on Mars, the life-saving properties of antibiotics and food preservation, along with the wonderful taste of beer. Using expert commentary, animation and stylised visuals, these videos provide an engaging introduction to microbiology, by examining the impact microbes have had on humans through a historical perspective, from Egyptian times to the present day.
