Feedback | |
A | These agents cause diseases only when given a special opportunity to enter deeper tissues of the body or to accumulate to levels that can harm the body. |
B | These diseases are caused by toxins released by a bacterium or fungus. |
C | These diseases are caused by microbes that already exist within the body. |
D | These diseases are caused by microbes that enter the body from the outside. |

4. The difference between an infection and an infectious disease is that an:
A. | infection never causes an infectious disease. |
B. | infection comes after the infectious disease has already started. |

D. | infectious disease and an infection can never involve the same microbe. |
ANS: C
Feedback | |
A | Some infections can lead to disease. |
B | An infection comes first. |
C | An infection does not always indicate disease, but disease (damage to the body) seldom results without infection (the exception is toxigenic diseases). |
D | This is not true. |
