Types of virus particles produced during wild-type HCMV infection.

Nuclear Cytoplasmic
A-capsids B-capsids C-capsids Dense bodies NIEP Virion
Lack scaffold as well as viral DNA and are believed to result from abortive viral DNA encapsidation Contain scaffold but lack viral DNA; likely to result from abortive capsid formation or DNA encapsidation Contain viral DNA and lack scaffold; likely representing nucleocapsids in the process of maturation Noninfectious capsidless particles and carry pp65 tegument protein as the main constituent Noninfectious enveloped particles (NIEP) produced when B-capsids mature Infectious virus particles produced when C-capsids mature, containing encapsidated viral DNA.
