List the pathogenic properties of viruses…
A
Cytopathic effects Prevent production of macromolecules Cells release lysosomes Antigenic bodies Infected cells adjacent to each other fuse to form giant cells Production of interferons Chromosomal change in the host cell Contact inhibition may be over ridden
