Hyperimmune globulin enriched for CMV (CMV-IGIV) is an immunoglobulin G (IgG) containing a standardized number of antibodies to cytomegalovirus. It may be used for the prophylaxis of cytomegalovirus disease associated with transplantation of kidney, lung, liver, pancreas, and heart.
People infected with CMV develop antibodies to it, initially IgM later IgG indicating current infection and immunity respectively. The virus can be diagnosed through viral isolation, or using blood, urine, or saliva samples. [3] When infected with CMV, most women have no symptoms, but some may have symptoms resembling mononucleosis.
Screening for cytomegalovirus is not mandatory in all jurisdictions, and positive donors may still donate at sperm banks. [3]Donor screening for cytomegalovirus (CMV) is carried out by testing for IgG antibodies against CMV that are produced if the donor ever has contracted CMV, which is the case in between 50% and 80% of adults.

Cytomegalovirus (CMV) (from cyto-'cell' via Greek κύτος kútos - 'container' + μέγας mégas 'big, megalo-' + -virus via Latin vīrus 'poison') is a genus of viruses in the order Herpesvirales, in the family Herpesviridae, [3] in the subfamily Betaherpesvirinae. Humans and other primates serve as natural hosts.
A Cytomegalovirus vaccine is a vaccine to prevent cytomegalovirus (CMV) infection or curb virus re-activation (symptomatic flare-ups) in persons already infected. Challenges in developing a vaccine include adeptness of CMV in evading the immune system and limited animal models. [ 1 ]
The water-accessible surface area of an IgG antibody. Immunoglobulin G (IgG) is a type of antibody. Representing approximately 75% of serum antibodies in humans, IgG is the most common type of antibody found in blood circulation. [1] IgG molecules are created and released by plasma B cells. Each IgG antibody has two paratopes.
CMV colitis may be clinically manifested with diarrhea (usually non-bloody), abdominal pain, weight loss and anorexia. The diagnosis of CMV colitis is based on serology, CMV antigen testing and colonoscopy with biopsy. Clinical suspicion should be aroused in the setting of immunocompromised patient but it is much rarer in immunocompetent patient.
Cytomegalovirus (CMV) is the most common congenital viral infection, usually transmitted through the placenta during pregnancy. Most neonates with congenital CMV infection will not have any symptoms, but a minority of infected newborns will have symptomatic infection.
