Problem Set Review Flashcards
What are the different types of viral infections?
Cytocidal (lytic)< >Effect on cellmorphological changes in cells (Cytopathic effect (CPE))Inhibition of cellular protein RNA and DNA synthesisCell deathUsually production of virons
Persistent (non-cytocidal) productive< >Effect on cellLittle metabolic disturbancesCell continues to grow and dividePossible loss of specialized functionAlways production of virons
Persistent (non-cytocidal) non-productive< >Usually no effect on cellUsually no production of virons
Transformation< >Effect on cell< >Alteration in cell morphologyTransformed cells may produce tumours in experimental animalsUsually by oncogenic RNA viruses
