Data Analysis Case Study

Analysis of data to study emergence of TcR on farms

In this case study, students synthesize information from different studies to arrive at a model to explain how human antibiotic resistant infections may be linked to antibiotic use on farms. Students are introduced development of antibiotic resistance within a population of bacteria through natural selection and the “One Health” concept that recognizes how the health of people is connected to our environment and the health of animals. Importantly, the evidence does not prove causation, but conveys to students how an accumulation of evidence compels us to adopt a particular model. The concept of selective pressure is reviewed.
