A lecture kept resonating in Joy Immak’s head as she talked with her grandmother. A few days before Christmas, Immak’s grandmother called to say her grandfather may be suffering from colitis once again.
His symptoms included fever, lethargy, severe abdominal pain, loss of appetite, and frequent diarrhea. Immak’s gut was telling her that it was more serious than colitis. She suspected a nasty bacterial infection she had just learned about in professor Helen Wing’s Biology 464 (Bacterial Pathogenesis) class.
