AMR through time with Katerina Guschanski

We have all heard about the importance of the gut microbiome. But how much do you know about the oral microbiome in our mouths? In the second interview with Dr Katerina Guschanski, Alastair Scott finds out all about how you can use the oral microbiome to study how antimicrobial resistance evolved through time. 

Dr Katerina Guschanski and her team extract ancient DNA from calcified dental calculus, to study their bacterial composition from before the existence of mass-produced antibiotics.
