The growing area of study linking human microbiota to health and wellbeing is seeing the development of new learning opportunities. The extent to which microorganisms on our skin and in our bodies meditate our lived experience can be understood through a free Coursera module, Gut check; exploring your microbiome. Maggie and I have completed the first two weeks, I thought potential future students might be interested in hearing more about what this course entails.
This MOOC is produced by the University of Colorado Boulder and the tutors are all linked to the institution; Professor Rob Knight, Dr. Jessica L. Metcalf and Dr. Katherine R. Amato.
As you might expect week one offers an overview of the subject area. Explanations are given for what microbes are in relation to each other (Bacteria, Archaea, Eukaryotes and Viruses) and all living organisms. The role of microbes more generally is explained before looking at how microbes and humans interact. Definitions include the distinction between human microbiota (a community of microbes), and the microbiota (the total genes in the microbiota).
The material highlights a number of interesting microbiome facts including that whilst humans share 99.99% of the same DNA, two humans may only have 10% of their microbiomes in common. This is one of the reasons why gut bacteria is thought to be influential in how we experience life. Although the majority of our microbes live in our gut, there are communities all over us (mouth, skin, vagina). We are born sterile and then communities of microbiota become established at a very early age, changes to these communities happen throughout our lives. The module material clearly illustrates that the microbes we are exposed to have an import role in our lives.
The first week provides a useful introduction to the subject and offers a context for later material. Beyond week 1, the course follows a much stronger academic path. Explaining the science behind the study of microbiota and moving onto subjects such as alpha diversity and ‘fuzzy microbes’. If you’ve tried the MOOC what do you think?
