Common viral antigens were detected, by fluorescent-antibody studies, in cells infected with herpes simplex virus 1, squirrel monkey herpesvirus 1, bovine rhinotracheitis, and equine abortion viruses. The two primate viruses showed slight cross-neutralization.

background: herpes virus group can persist in the latent form in the body, pneumocystis jerovecii, on the other hand, is a fungus which is ubiquitous in the respiratory tract of mammals, with 90% of adult human beings possessing antibodies to this organism. concomitant presence of different microorganisms, may result in one microorganism altering the activity of another. objectives: to determin...

P ATIENTS WITH LYMPHOMA, leukemia, multiple myeloma, or other conditions characterized by an altered immunologic state have an increased susceptibility to the manifestations of common viral infections. In such patients, disseminated infections with the DNA viruses, herpes simplex, and herpes zoster have carried a poor prognosis.1’2 Various attempts have been made to treat these disseminated inf...

There are six herpes viruses, three of which, the varicella-zoster virus and the herpes simplex viruses types 1 and 2, are of particular concern to patients and staff in critical care units. These viruses, especially in their reactivated states, may present atypically in critically ill and immune-suppressed patients, and, by the time the diagnosis is made, exposures of other patients and clinic...

Background: Recent studies have suggested the role of herpes viruses in the etiopathogenesis of periodontal disease. Very few studies have explored the role of herpes virus in periodontal disease. The occurrence of herpes viruses may also vary depending on the race of the population studied. Herpes Simplex Virus (HSV 1&2) is frequently detected in gingival crevicular fluid of periodontal pocket...

Static latency is the hallmark of all herpes viruses. The varicella zoster virus, for instance, causes varicella (chickenpox), and after a latent phase of between 5 and 40 years, it can give rise to herpes zoster (shingles). This latency and the subsequent reactivation has intrigued and puzzled virologists. Although several factors have been suggested, it is unknown what triggers reactivation. ...

many must be the result of using impure systems and of secondary effects or else they are the product of a multiplicity of phenomena with similar end results. Dr. Vilcek is a splitter; he gives the impression that no unifying principle exists in the interferon system, but that there are several physically diverse interferons produced by the same cell and that cells may be induced to produce the...

Viruses can only reproduce by infecting live cells. During their replication, some viruses manipulate the host cell machinery in such a way that may cause the host cell to reproduce out of control and become carcinogenesis. These viruses are known as oncogenic viruses, also named as “tumor viruses” or “cancer viruses”. In 1909, Francis Peyton Rous showed that cancer could be transmitted through...

PURPOSE Although a variety of malignant tumors are susceptible to therapy with oncolytic herpes simplex viruses, the determinants of tumor sensitivity to these viruses are poorly understood. Nectin-1 is a cell surface adhesion molecule that is a component of intercellular adherens junctions and also functions as a herpes viral receptor. Because highly invasive cells may have decreased intercell...

several complications attributed with herpes virus related infections and the emergence of drug resistant viruses prompt scientists to search for new drugs. several terpenoids and coumarins have shown anti hsv effects while no sesquiterpene coumarin have been previously tested for hsv treatment. three sesquiterpene coumarins [badrakemin acetate (1), kellerin (2) and samarcandin diasteromer (3) ...
