objective: herpes simplex virus (hsvs) is a widespread human infectious agent, responsible for persistent and latent infections. herpes simplex virus infections are usually continually recurrent in the normal population and represent a significant cause of complications in immunocompromised patients. materials and methods: in this study hsvs were propagated in bk cells and more than 502 sample...

background and objectives: human herpes 6 virus (hhv-6) could remain latent and chronic in the host cells after primary infection. hhv-6 genome encodes certain trans activation proteins which may results in development of malignantlymphoma. the association of human herpes six virus (hhv-6) infection and hodgkin and non-hodgkin lymphomas is strongly supported by epidemiological studies. the aim ...

Both human herpes viruses and Chlamydia are highly prevalent in the human population and are detected together in different human disorders. Here, we demonstrate that co-infection with human herpes virus 6 (HHV6) interferes with the developmental cycle of C. trachomatis and induces persistence. Induction of chlamydial persistence by HHV6 is independent of productive virus infection, but require...

conclusions this epidemiological study indicated different rates and transmission risks for these viruses. hcv was the most contagious viral infection and htlv-i was the weakest in the prisoners. apart from kshv infection which its prevalence was as twice as in the general population, the prevalence of hbv and htlv-i in prisoners was nearly in ranges of the general population. background prison...

INTRODUCTION Chronic rhinosinusitis with nasal polyps is a multifactorial disease entity with an unclear pathogenesis. Contradictory data exist in the literature on the potential implication of viral elements in adult patients with chronic rhinosinusitis. OBJECTIVE To compare the prevalence of human herpes viruses (1-6) and Human Papilloma Virus in adult patients with chronic rhinosinusitis w...

background: colorectal cancer is one of the most common malignancies worldwide with more than one million new cases diagnosed each year . the aim of this study is to investigate the prevalence of herpes simplex virus and epstein-barr virus in patients with colorectal carcinomas and polyps in comparison with healthy subjects by using the polymerase chain reaction technique. methods: in this anal...

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 ...

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 ...

Herpes virus infections are frequent in renal transplant recipients. Some herpes viruses are not only responsible for life-threatening infections and renal graft injury but can also increase the risk of malignancy. Three herpes viruses, namely cytomegalovirus (CMV) or human herpes virus 5, Epstein-Barr virus (EBV) or herpes virus 4 and human herpes virus 8 (HHV8), may play an oncogenic role. Th...
