background: the aim of this study was to determine the prevalence and viral load of epstein–barr virus (ebv) and human herpesvirus‑6 (hhv‑6) in different histopathologic grades of oral squamous cell carcinoma (oscc). methods: forty‑five formalin‑fixed paraffin‑embedded tissue section of oscc patients were analyzed by quantitative real‑time polymerase chain reaction for detection of ebv and hhv‑...

background: among the eight known human herpes viruses, epstein- barr virus (ebv) is considered to be sexually transmissible. this study was conducted to evaluate the seroepidemiology of this infection in married and unmarried iranian couples. methods: in this comparative observational and cross-sectional study, 160 men and women were divided into married and unmarried groups. serum igg and igm...

opportunistic infections are the leading cause of hospitalization and morbidity in human immunodeficiency virus (hiv) positive patients and are the most common cause of death between them. we aimed to measure igg antibody against ebv viral capsid antigen (ebv-vca igg) to determine the seroprevalence of this infection in hiv-positive population. a case-control study between september 2011 and oc...

introduction: quantification of epstein - barr virus (ebv) in peripheral blood mononuclear cells (pbmnc) of allogenic bone marrow transplant (bmt) recipients is important because ebv-associated posttransplant lymphoproliferative disease (ptld) can occur after transplantation due to immunosup-pression therapy. methods: to this end we chose real-time pcr using taqman probe. for the standard curve...

conclusions considering the results, accurate and on time diagnosis of ebv primary infection in both children and adolescents will help prevent unnecessary hospitalization, medication and incorrect medical decisions. in addition, this will decrease further treatment costs and related medical procedures. background many children become infected with epstein-barr virus (ebv) during their childhoo...

Epstein-Barr virus obtained by superinfection of Raji cells with Epstein-Barr virus recovered from P3HR1 cells (HRI virus) transformed human lymphocytes, but it did not superinfect Raji cells. A human lymphoblastoid cell line, HLB, established by such transformation contained 22 Epstein-Barr virus genomes per cell and Epstein-Barr virus-associated nuclear antigen, and a few cells contained earl...

ulcerative colitis (uc) is one type of inflammatory bowel disease (ibd). herpes viruses have been suggested as possible etiological agents of uc and crohn’s disease (cd). the aim of this study was to investigate the prevalence of herpes simplex virus (hsv), cytomegalovirus (cmv) and epstein-barr virus (ebv) in patients with uc in comparison with healthy subjects by using pcr technique. in this ...

Epidemiological and serological evidence has suggested a role for Epstein-Barr virus infection in the aetiology of multiple sclerosis. Epstein-Barr virus-specific RNA was looked for in the brains of 10 patients with multiple sclerosis by in situ hybridisation. A total of 21 plaques was examined. In all of these preservation of RNA was shown by hybridisation of control probes to mitochondrial rR...

Chronic active Epstein-Barr virus infection manifests as a combination of persistent infectious mononucleosis-like symptoms and high viral load in apparently immunocompetent patients. It is closely related to Epstein-Barr virus-associated hemophagocytic lymphohistiocytosis. These 2 abnormal Epstein-Barr virus-associated diseases are seldom reported in individuals other than Japanese children an...

We studied a group of 54 children with Burkitt's lymphoma from Southeastern Brazil, where epidemiological status of Burkitt's lymphoma is poorly understood. Epstein-Barr virus association showed an intermediate frequency (~60%) between endemic and sporadic subtypes. Median age was five years. Epstein-Barr virus infection was significantly associated to low age (Epstein-Barr virus(+) four years ...
