Cytomegalovirus (CMV), the fifth member of the human herpesvirus family, is one of the largest viruses known to cause clinical disease. It is a double-stranded DNA virus that belongs to the beta-herpesvirus subfamily, along with human herpesviruses 6A, 6B, and 7. CMV was first associated with an infectious mononucleosis-like illness in healthy individuals in 1965 ( 1 ). Currently, it is known to cause a wide range of clinical syndromes, from asymptomatic infection in healthy hosts, to severe and even fatal disease in immunocompromised individuals, such as transplant recipients.

ASM Press, Washington, DC. doi: 10.1128/microbiolspec.DMIH2-0022-2015This biopsy specimen from a patient with cytomegalovirus colitis shows a classic “owl-eye” intranuclear inclusion (arrow) and intracytoplasmic inclusions. The dense intranuclear inclusion with surrounding halo is formed when the mass of viral particles shrinks away from the nuclear membrane during fixation. While herpes simplex virus intranuclear inclusions can have a similar appearance, CMV is the only member of the herpesviridae family that contains both intranuclear and intracytoplasmic inclusions. Hematoxylin and eosin stain, 1000x oil immersion.
