  I have never studied transmission of disease between different animals, but usually this is because the germ mutates and then becomes able to infect a different type of animal (or multiple types of animal). This is the case with the influenza virus, which causes swine flu – infects pigs but also humans. Mutations occurred that allowed it to infect humans!

  At the moment I look at the behaviours we humans do which increase our risk of catching and spreading diseases. Things like not washing our hands between working with animals and eating our lunch. I am not actually looking at a specific disease at the moment but i generally want to know how these behaviour help resistant bacteria spread. So far we know that very simple behaviours like washing hands with soap can slow this process down, now we have to convince people to do it!
