Herpes B-virus,cercopithecine herpesvirus 1;herpesvirus simian endemic in Asian macaques is related to herpes simplex(HSV) type 1 in humans; infection with herpes B-virus in humans can result in fatal encephalitis and neurologic impairment. Human infections have been by bites, scratches, and percutaneous inoculation. HerpesB-virus infection causes minimal morbidity in macaques. Inhumans herpes ...

The Herpes simplex viruses are responsible for a broad-spectrum of diseases affecting all age groups across the developed and developing world. The viruses are members of the herpesvirus family, which also includes the human pathogens Varicella-Zoster virus, Epstein-Barr virus, Cytomegalovirus, Human herpes virus -6 and -8. Herpes simplex virus type -1 (HSV-1) and -2 (HSV-2) are serotypically d...

background and aims: several drugs are being used in treatment of hsv infection in human but still introducing an effective safe drug is desirable. methods: we investigated the inhibitory effect of morphine on replication of hsv in vitro. results: the results indicated that a concentration of up to 200 ug/ml morphine had a limited effect on vero cell viability. at this concentration the growth ...

Kaposi ' s sarcoma (KS) i s a mul t i focal angioproliferative disease characterised by transdifferentiation of human herpes virus type 8 (HHV-8) infected endothelial cells into spindle-shaped cells, followed by cytokine-dependent transformation, proliferation, neovascularisation and inflammatory cell infiltration. Trans-differentiation is the conversion of differentiated cells either morpholog...

Herpes simplex virus is most probably maintained in the ganglion neurons of the peripheral nervous system of humans in a latent form that can reactivate to produce recurrent disease. As an approximation of this cell-virus interaction, we have constructed a herpes simplex virus latency in vitro model system using human fetus sensory neurons as the host cell. Human fetus neurons were characterize...

Herpes zoster (Shingles; Zona) is an acute infectious skin disease that is caused by the reactivation of varicella zoster virus (VZV). After the initial infection (chickenpox) or vaccination, the virus remains inactive or latent in the dorsal root ganglia (DRG); when decreasing cell mediated immunity (CMI) occurs, the virus is reactivated from a latent phase to a lytic phase and frequently repl...

Human herpes virus 8 infection is the primary and necessary factor in the development of Kaposi's sarcoma, but is not sufficient per se to trigger the onset of the disease. In order to search for virological cofactors associated with the occurrence of the disease, we investigated the prevalence of active infection by two newly discovered viruses, hepatitis G virus and TT virus, among patients w...

2 Varicella-zoster virus (VZV) is a human alphaherpesvirus that infects sensory ganglia 3 and reactivates from latency to cause herpes zoster. VZV replication was examined in human 4 dorsal root ganglia (DRG) xenografts in mice with severe combined immunodeficiency using 5 multiscale correlative immunofluorescence and electron microscopy (IF-EM). These 6 experiments showed the presence of VZV g...

background: the present study sought to investigate molecular evidence for association between the presence of herpes simplex virus (hsv), cytomegalovirus (cmv), and epstein-barr virus (ebv) in crc and colorectal polyp by using the pcr method in iran. methods: in this analytical case-control study, we selected 15 patients with crc, 20 patients with colorectal polyp, and 35 patients without mali...
