cytoplasm
productive infection steps
enter, find proper machinary, exit
non-productive
no infection, latent virus or oncogenic transformation
phases of viral multiplication
attachment, penetration, uncoat, virus component synthesis, assembly, release
naked virus release from cell via this mechanism
lysis
enveloped virus exit cell via this mode
budding
examples of Cytopathic effects (CPE)
fusion and cell rounding
function of antivirals
inhibit a step in viral multiplication
