Cytomegaloviruses. Coloured transmission electron micrograph (TEM) of virions (virus particles) of cytomegalovirus in a lung cell. Rounded viruses (coloured magenta) are seen within the contents of the cell. Each virus consists of a protein coat or capsid inside which is contained the DNA viral genetic code. Cytomegalovirus (CMV), a member of the herpesvirus group, causes infected cells to enlarge. Infection is very common and not danger- ous. However, serious infections can occur in people with lowered immunity, such as the elderly and those with AIDS. Pregnant women can pass the virus to their unborn child, leading to malform- ations.
