...sor of molecular microbiology. "First, you have to detect
the potential pathogen in someone who's sick. Then you have to develop a way to grow the new microorganism in the laboratory. Finally, you have to show that you can make an animal model sick by exposing it to the microorganism." These steps, known t...
