Evidence of viral growth in cell culture is commonly seen as

  • A.gas production in a fermentation tube
  • B.a colour change of an indicator dye due to lactose fermentation
  • C.cytopathic effects or inclusions in the cells
  • D.turbidity of the culture medium

Answer: C

Damage to the cell sheet, or inclusions visible within cells, signals that a virus is replicating. Turbidity, gas and fermentation reactions are all bacterial phenomena, since they depend on metabolism the virus does not possess.
