Mitotic chromosome segregation is mediated by spindle microtubules attached to centromeres. Recent studies, however, revealed that acentric DNA molecules, such as viral replicons and double minute chromosomes, can efficiently segregate into daughter cells by associating with mitotic chromosomes. Based on this similarity between viral and cellular acentric molecules, we introduced Epstein-Barr v...

Background Epstein-Barr virus (EBV) infects almost a large percent of the world’s adult population. Antibody prevalence rates reach 95% or higher among elderly individuals. Even in the pediatric population, Epstein Barr infection is common. Young children most likely acquire primary EBV infection from close contact that involves exchange of oral secretions via shared items such as toys, bottles...

A monoclonal antibody (mAb) designated 55H3 was produced by using chemically induced Epstein-Barr virus genome-positive B95-8 cells. mAb 55H3, which reacted with an 85- to 80-kDa polypeptide, neutralized Epstein-Barr virus-encoded DNA polymerase activity in crude extracts of chemically induced M-ABA, HR-1, and B95-8 cells, as well as the partially purified Epstein-Barr virus DNA polymerase in a...

BACKGROUND Complete resection seemed to be curative in patients with Castleman disease of any location but the disease is likely to be reactive in its pathogenesis. The relation between Epstein-Barr virus and Castleman disease has not been elucidated. We tried to define the role of Epstein-Barr virus in the pathogenesis of Castleman disease. METHODS 20 cases of Castleman disease were retrospe...

Epstein-Barr virus transformed human lymphocytes despite the presence of up to 500 microM acyclovir [9-(2-hydroxyethoxymethyl)guanine], a viral DNA polymerase inhibitor. The transformed cells contained multiple Epstein-Barr virus genome copy numbers. Functional viral DNA polymerase is probably not required for cell transformation and the initial amplification of the viral genome.

Epstein Barr virus (EBV)-related diseases encompass both acute infections that result in acute infectious mononucleosis and chronic infections that result in lymphoproliferative malignant diseases. While classical inflammatory parameters such as C-reactive protein (CRP) have proven their usefulness during bacterial and fungal infections, they are often low and nondiscriminatory in viral infecti...

The prevalence, presenting clinical and pathological characteristics, and outcomes for patients with diffuse large B-cell lymphoma that is Epstein-Barr virus positive remain uncertain as does the impact of congenital or iatrogenic immunosuppression. Patients with newly diagnosed diffuse large B-cell lymphoma with available tissue arrays were identified from the University of Iowa/Mayo Clinic Mo...

We report the first genome sequence of the methicillin-resistant Staphylococcus pseudintermedius (MRSP) strain E140, isolated from a canine bite wound infection in Denmark. This strain represents the dominant clonal lineage associated with canine MRSP infections in Europe.

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 ...

BACKGROUND Natural killer cell function is regulated by inhibitory and activating killer cell immunoglobulin-like receptors (KIR). Previous studies have documented associations of KIR genotype with the risk of cytomegalovirus (CMV) replication after solid organ transplantation. METHODS In this study of 649 solid organ transplant recipients, followed prospectively for infectious disease events...
