Question

(recall Koch's postulates): Suppose you suspected that a pathogenic bacteria was the causative agent of emphysema (a chronic disease that affect mammalian lungs). To demonstrate this, you obtained samples from hundreds of patients and you identified a bacterial species that was present in every case. This bacterial species was not observed in disease-free controls. A phlegm-covered section from a diseased lung was transferred into a healthy mouse, and the mouse developed the disease. But, other people still aren't convinced that the bacteria you identified causes emphysema. Why not? What step did you fail to perform?
