Cytopathic effect refers to

  • A.the antibody response to a virus
  • B.the ability of a virus to survive drying
  • C.the count of physical particles in a sample
  • D.visible damage to cells caused by viral infection

Answer: D

Correct answer: visible damage to cells caused by viral infection

The cytopathic effect is what the infection does to the cell as seen down the microscope - rounding, detachment, syncytium formation, inclusion bodies, lysis. It is the basis of detecting a virus in cell culture, and the pattern is often characteristic enough to suggest which virus is present before any other test is done.
