Demonstrate that the bacterium is 3. Isolate the bacterium from an inte one that initially caused the infection 4. Infect another human patient to se A) I and 2 B) 1 and 3 um and intestinal disease, researchers have shown that the out in healthy individuals. What other experiment(s) do solutely sure that the bacte ure that the bacterium is responsible for the disease? and demonstrate that healthy animals injected with this culture 3. Iso personale shume volumis but not in healus erium is not able to live outside of humans or animals an inferte sick animal and demonstrate that it is the same bacterium as the lent to see if they show symptoms.

A) desiccation B) over abundance of oxygen C) sperm transfer D) animal predation

Please answer all!! Thank you :)

Answer 1

Ang Option B is correct 9f we want to confirm whether this bacterium is responsible for disease or not Isolate the bacterium in a pure culture and inject the healthy animal with this to see whether Similar symptoms comes 07 not. (li) Also isolate the bacterium from infected sick animal and demonstrate that same bacterium cause it or not. SO B correct.
