2.      The disease agent is too small to be seen under a light microscope.
3.      There are no known antibiotics that are effective against the disease.
4.      The genetic material of the disease agent is DNA.
5.      The disease agent cannot be cultured using any known culture medium.

Is the disease agent most likely a bacterium or a virus? Explain your answer. Write your answer in the space below.
