Background: Varicella zoster virus (VZV) infection is one of the nosocomial infections and healthcare workers (HCWs) are at high risk group who work in the hospital with likelihood of varicella acquisition or transmission. This study evaluated the VZV seroprevalence in this high risk population in Babol, Iran. Methods: Serological testing for VZV using enzyme linked immunosorbent assay (ELISA)...

background: varicella zoster virus (vzv) causes chickenpox in children and zoster (zona) in the elderly. using rflp-pcr method for detection of vzv specific snps orf38, 54 and 62 could  distinguish the profile of vzv isolates. the aim of this study was to investigate enzymatic digestion pattern of vzv orf38 and orf54 in chickenpox patients using rflp technique. methods: thirty-eight chickenpox ...

abstract background: varicella is a highly contagious and dangerous disease especially in immunocompromised patients. children with cancer are at increased risk of severe illness and may fatal cases occur. vaccination from vzv ( varicella zoster vaccine) infection can be safe, immunogenic, and effective in children with leukemia who meet the criteria and are at the risk of serious disease or de...

INTRODUCTION In contrast to varicella zoster virus (VZV) primary infection, VZV vaccination does not seem to provide lifelong immunity against varicella. Because more people get vaccinated every year, the development of sensitive serological test systems for the detection of protective anti-VZV IgG will become important in the future. METHODS We have previously developed a novel VZV line assa...

The Varicella-Zoster Virus (VZV) genome contains both cis-acting and trans-acting elements, which are important in viral DNA replication. The cis-acting elements consist of two copies of oriS, and the trans-acting elements are those genes whose products are required for virus DNA replication. It has been shown that each of the seven genes required for ori-dependent DNA synthesis of Herpes Simpl...

Commercial serologic assays for varicella-zoster virus (VZV), which enable reliable determination of VZV immune status and are amenable to automation, are needed. The present study compares the automated performance of the VZV whole-cell enzyme-linked immunosorbent assay (ELISA) Enzygnost anti-VZV/IgG, the Euroimmun anti-VZV ELISA (IgG) based on highly purified viral proteins, and the VZV glyco...

Abstract Background: Varicella is a highly contagious and dangerous disease especially in immunocompromised patients. Children with cancer are at increased risk of severe illness and may fatal cases occur. Vaccination from VZV ( varicella zoster vaccine) infection can be safe, immunogenic, and effective in children with leukemia who meet the criteria and are at the risk of serious disea...

Varicella-zoster virus (VZV) causes chicken pox (varicella), becomes latent in dorsal root ganglia, and reactivates decades later to cause shingles (zoster). During latency, the entire VZV genome is present in a circular form, from which genes 21, 29, 62, and 63 are transcribed. Immediate-early (IE) VZV genes 62 and 63 encode regulators of virus gene transcription, and VZV gene 29 encodes a maj...

Varicella-zoster virus (VZV) is an alphaherpesvirus with the characteristic neurotropism of this group, but VZV also infects T cells productively and downregulates major histocompatibility complex (MHC) class I expression on infected T cells, as shown in the SCID-hu mouse model. T-cell tropism is likely to be critical for the cell-associated viremia associated with primary VZV infection. In the...
