THE DISEASE DETECTIVE
Six children were in the hospital. They were very sick, but the doctors didn't know what to do. They called Dr. Richard Besser, an expert on strange illnesses.  Dr. Besser knew just what to do.
Finding a Cause
First, Dr. Besser needed to find the cause of the illness. He used a microscope to look for germs like bacteria in the children's bodies. Dr. Besser found that all the children had a strain of the bacteria E. coli. Then he looked at the bacteria's DNA. The DNA showed him that this strain of E. coli was dangerous to humans.
Where Did It Come From?
Dr. Besser knew E. coli could move from animals to humans. Perhaps the children had touched animals that carried the bacteria? Besser found other E. coli cases in the area where the children lived. But it wasn't enough.
Besser then made a list of what the sick children had eaten. They had all eaten cheese, apple juice, and fish. He then made a list of what healthy children in the area had eaten, and compared his lists. They had eaten the cheese and fish, but not the apple juice.
Case Closed
Besser went to where the apple juice was made. He saw that there were animals around the apple trees, and he saw the workers using dirty apples that had fallen on the ground. More importantly, he saw that the apples were not washed before the juice was made, and that the juice was not heated. Doing these things would kill the bacteria. Besser then knew it was the apple juice that made the children sick.
Besser's E. coli case has a happy ending. The children got better. And what Besser learned that day now helps keep others safe.
Which of the following things happened first?
A.Dr. Besser found out what made the children sick.
B.Dr. Besser made a list of what the healthy children ate.
C.Dr. Besser went to where the apple juice was made.
D.Dr. Besser made a list of what the sick children ate.
