sick. What other experiment do researchers need to perform to be absolutely sure that the bacterium is
responsible for the disease?
A) Demonstrate that the bacterium belongs to the pathogenic lineage
B) Demonstrate that the bacterium is not able to live outside of humans or animals
C) Isolate bacterium from an infected sick animal and demonstrate that it is the same bacterium as the
one used for infection
