An infection in which virus is produced continuously without killing the cell is described as

  • A.abortive
  • B.lytic
  • C.latent
  • D.persistent

Answer: D

Correct answer: persistent

In a persistent infection the cell continues to release virus while remaining alive and dividing, so the culture is chronically infected rather than destroyed. That is what separates it from the lytic infection, which kills the cell to release the progeny, and from latency, in which the genome is retained but little or no virus is made.
