Questions we can address with bioinformatic analysis and genome sequence comparison:

Questions we can address with bioinformatic analysis and genome sequence comparison: Why is a given pathogen more virulent? What is the geographic range of different pathogen strains and how are they changing with time? Why does a given pathogen attack one host but not another?.
