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.
An ELISA technique for CMV-specific IgM is available, but may give false-positive results unless steps are taken to remove rheumatoid factor or most of the IgG antibody before the serum sample is tested. Because CMV-specific IgM may be produced in low levels in reactivated CMV infection, its presence is not always indicative of primary infection.
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.
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.
Screening for cytomegalovirus is not mandatory in all jurisdictions, and positive donors may still donate at sperm banks.

Anti-HBs concentration falls as the infection resolves but does not serorevert completely, and anti-HBs IgG remains positive for years as a sign of immunity. [65] Hepatitis B e-antigen (HBeAg) is a sign of current infectivity. An individual who is seropositive for HBeAg can infect others. [67]
