Herpes zoster (shingles), a painful and disabling disease, affects an estimated 1 million individuals in the United States annually and results in significant morbidity, lost productivity, and diminished quality of life. Herpes zoster constitutes the reactivation of varicella-zoster virus (VZV), the same virus that causes chickenpox. After resolution of chickenpox, VZV remains dormant in dorsal...
The association of mumps with peripheral facial paralysis has been suggested, but its pathogenesis remains unclear. An 8-year-old girl simultaneously developed left peripheral facial paralysis, ipsilateral cervical herpes zoster, and bilateral mumps sialadenitis. Elevated anti-mumps and anti-varicella zoster virus IgM antibodies in serological testing indicated recent infection of mumps and rea...
A patient with AIDS developed chronic, progressive encephalitis. Pathologic changes indicated that the encephalitis was produced primarily by a human herpesvirus. Hybridization of radiolabeled RNA probes transcribed from cloned DNA fragments of varicella-zoster virus (VZV), herpes simplex virus, cytomegalovirus, and the human immunodeficiency virus to DNA extracted from the patient's brain iden...
A real-time PCR assay was developed to identify varicella-zoster virus (VZV) and herpes simplex virus (HSV) DNA in clinical specimens from subjects with suspected herpes zoster (HZ; shingles). Three sets of primers and probes were used in separate PCR reactions to detect and discriminate among wild-type VZV (VZV-WT), Oka vaccine strain VZV (VZV-Oka), and HSV DNA, and the reaction for each virus...
background: varicella–zoster virus (vzv) causes herpes zoster and varicella (chicken-pox), usually a mild disease which is diagnosed clinically with few complications. however, in neonates and healthy adults it can have a severe presentation. herpes zoster results from vzv reactivation later in life. objective: to determine the seroprevalence of vzv in elementary school children aged 6-10 years...
BACKGROUND Varicella-zoster virus (VZV) is the etiologic agent of two diseases, varicella (chicken pox) and zoster (shingles). Varicella is a self- limited infection, while zoster is mainly a disease of adults. The present study was conducted to isolate VZV from clinically diagnosed children using cell cultures and compare the activity of liquorice powder extract, an alternative herbal antivira...
Varicella zoster virus (VZV) is a ubiquitous, exclusively human alphaherpesvirus. Primary infection usually results in varicella (chickenpox), after which VZV becomes latent in ganglionic neurons along the entire neuraxis. As VZV-specific cell-mediated immunity declines in elderly and immunocompromised individuals, VZV reactivates and causes herpes zoster (shingles), frequently complicated by p...
Infection of human neurons in vitro with varicella-zoster virus (VZV) at a low multiplicity of infection does not result in a cytopathic effect (CPE) within 14 days postinfection (dpi), despite production of infectious virus. We showed that by 28 dpi a CPE ultimately developed in infected neurons and that interferon gamma inhibited not only the CPE but also VZV DNA accumulation, transcription, ...
Varicella and herpes zoster during pregnancy has been associated with birth defects, neonatal varicella, herpes zoster in newborns and infants. The aim of the present study was to determine the consequences for the neonates, whose mothers were closely exposed to varicella zoster virus (VZV) during pregnancy. Fifty six pregnant women with uncertain histories of prior VZV infection, after a close...
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...
