Background: Breast cancer is the most common malignancy in females worldwide. Several etiological factors including environmental factors have been recognized for breast cancer. Epstein Barr virus as a viral etiological factor has been proposed. So far, several studies have investigated the relationship between development of breast cancer and Epstein Barr virus, but few have been done in Iran....
In southern Tasmania, Australia, primary Epstein-Barr virus infection occurs in adults greater than 30 years of age at a higher frequency (approximately 13% of all cases) than is generally reported for other parts of the world, and approximately 7% of the general population of the region have no antibodies to the virus. Epstein-Barr virus should not be overlooked as a possible cause of disease ...
A 16-month-old boy was admitted because of cough that had lasted for 10 days. The patient showed severe hepatomegaly incidentally, and dual positivity of Immunoglobulin (Ig) M to Epstein-Barr virus (EBV) viral capsid antigen (VCA) and cytomegalovirus (CMV). On the basis of seroconversion to Epstein-Barr nuclear antigen (EBNA) Ig G positivity and reduced CMV Ig M titer with persistently negative...

 An elegant study reported dysmorphic cells and syncytia in deceased's lungs for COVID-19. The authors reasonably considered that most of these syncytia-forming were pneumocytes, as identified by specific biomarkers. However, cellular dysmorphism are pathological features common other respiratory infections caused different viruses, including human syncytial virus (HRSV) Epst...
The Enzygnost alpha method was tested against the complement fixation test and anti-VCA immunofluorescence to determine the respective titers of anti-cytomegalovirus and anti-Epstein-Barr virus immunoglobulin G antibodies. For cytomegalovirus, the Enzygnost results showed 97.99% agreement with the readings obtained by the alternative method, with 100% sensitivity and 93.7% specificity. For Epst...
We describe a unique case of fulminant infectious mononucleosis and recurrent Epstein-Barr virus reactivation presenting in an adolescent. Detailed assays of Epstein-Barr virus-specific T cell immunity revealed defects in the patient's T cell receptor signalling pathway characterized by a lack of interleukin-2 and CD25 expression, which may have contributed to her clinical course. Allogeneic st...
A case of lymphoepithelial carcinoma occurring in the left submandibular salivary gland is presented. Histologic features of this rare malignancy are described in detail. This unusual carcinoma has been described frequently in Eskimos and is usually located in the parotid gland. The raised serum IgG to Epstein-Barr virus capsid antigen suggests a causal relationship between Epstein-Barr virus a...
A B-lymphoid cell line was established from a normal gorilla. The cells contained Epstein-Barr virus-related antigens, and herpesvirus particles were demonstrated by electron microscopy. DNA-DNA reassociation kinétics revealed 30 to 40% hybridization to Epstein-Barr virus with 50 genomes per cell. Examination of the viral nuclear antigen with gorilla sera showed this to be a unique isolate term...
Lymphoproliferative disorders following liver transplantation are often Epstein-Barr virus (EBV)-related highgrade B cell lymphomas. EBV-negative and low-grade lymphoma is a very rare condition after cadaveric as well as living donor liver transplantation (LDLT). Herein we report a case of follicular lymphoma with negative EBV viral capsid antigen (VCA), IgM, IgG and Epstein-Barr virus-encoded ...
Abstract Introduction Epstein-Barr virus (EBV) infection can present with a variety of manifestation. Case Report Here we present a case of a 7 yearold immunocompetent girl who came with acute abdominal pain , had echocardiographic evidence of myocardial dysfunction and finally was diagnosed as a case of serologically proven acute EBV infection. Conclusion Isolated gastrointestinal symptoms can...
