How is it that we are not in a state of continuous infection from the microbes we encounter every day?
Our environment contains masses of microorganisms, many of which reside as commensal organisms on our body’s mucosal and epithelial surfaces without causing disease. What two features distinguish a pathogenic microbe from these commensal microbes?
