The week of October 6th is antibiotic resistance week. We will explore how pathogens evolve resistance to antimicrobial agents and how medical professionals and researchers can develop strategies to reduce the evolution of resistance. On tuesday we will discuss 4 strategies for reducing bacterial evolution of resistance. 1) Limiting use […]

Thanks to everybody for a lively discussion of the evolution of virulence today; pictured here is a rabbit victim of myxoma virus, the classic example used to promote the idea that pathogens will evolve towards a more benign state. Key points from today: 1) Pathogens do not always evolve towards […]

It is thought that much human evolution occurred during the Pleistocene – 2.8 million to 12 thousand years ago. What are the consequences of genes optimized for a Pleistocene environment now expressed in the modern environment… radically different food, new technology, petro-chemicals, artificial light, drugs? Novelty and extreme environments often […]
