Epstein-Barr virus

 [ep´stīn bahr´]
a herpesvirus of the genus Lymphocryptovirus, one of the etiologic agents of infectious mononucleosis. It has been isolated from cells cultured from Burkitt's lymphoma and has been found in certain cases of nasopharyngeal carcinoma. There may be an association between EBV and chronic fatigue syndrome. High titers of EBV are present in some tumors, but a causative role has not been proven. Called also EB virus.

Epstein-Barr virus

A double-stranded DNA virus which belongs to the 8-member herpesvirus family. Immature EBV particles are 75–80 nm and appear in the cytoplasm and nucleus of infected host cells; mature infectious particles are 150–200 nm and are cytoplasmic. EBV was first found in a Ugandan child with Burkitt’s lymphoma.

Disease associations
Infectious mononucleosis is the most common disease associated with EBV infection. Others include aplastic anaemia, Burkitt’s lymphoma (usually African type), hairy leukoplakia, histiocytic sarcoma in patients with kidney transplants and the immunocompromised. EBV facilitates the development of lymphoproliferative disorders (e.g., Hodgkin and non-Hodgkin lymphomas), angiocentric immunoproliferative lesions, Izumi fever, immunoblastic lymphoma, thymic carcinoma, and undifferentiated nasopharyngeal carcinoma. Serologic markers are used to detect active EBV infection and determine the stage of infection.

Epstein-Barr virus

Human herpesvirus-4 Virology A double-stranded DNA virus that causes infectious mononucleosis, and belongs to the 8-member herpesvirus family; immature EBV particles are 75-80 nm and appear in the cytoplasm and nucleus; mature infectious particles are 150-200 nm and are cytoplasmic; it is associated with aplastic anemia, Burkitt's lymphoma–usually African type, hairy leukoplakia, histiocytic sarcoma in renal transplants and immunocompromise; EBV facilitate lymphoproliferative disorders–eg, Hodgkin's disease–ID'd by PCR, Southern blot, and in situ hybridization, angiocentric immunoproliferative lesions, NHL, Izumi fever, immunoblastic lymphoma, thymic carcinoma, undifferentiated nasopharyngeal carcinoma–mainland China; several serologic markers are used to detect active EBV infection, and determine the stage of infection

Early Antigen Ab Present early in infection, usually disappears.
Viral Capsid Ab-IgG ↑ After infection and remains positive; ↑ dramatically with re-infection.
Viral Capsid Ab-IgM ↑ With infection and disappears; ↑ with re-infection.
Nuclear Ab –IgG ↑ With infection and remains positive.
Nuclear Ab –IgM ↑ For 4-6 weeks; post-infection becomes negative; ↑ with re-infection

A member of the herpes family of viruses and the cause of GLANDULAR FEVER (infective mononucleosis). It is also associated with cancer of the back of the nose (nasopharyngeal carcinoma) in Chinese people and with BURKITT'S LYMPHOMA.
