Indirectly cytopathic viruses kill cells by provoking an
A. injury to DNA.
B.immune response.
C. injury to the cell membrane.
D. influx of potassium.
The answer is B. In contrast to directly cytopathic viruses, which
cause cell death by damaging the cell membrane indirectly, cytopathic viruses
produce antigenic proteins that are inserted into the cell membrane and are
capable of evoking an immune response.
Attack by immune lymphocytes, which recognize the viral protein as
foreign, destroys the cell membrane.
