1. Current status of herpesvirus identification in the oral cavity of HIV-infected children
INTRODUCTION: Some viruses of the Herpesviridae family are frequently the etiologic agents of oral lesions associated with HIV. The aim of this study was to identify the presence of herpes simplex virus types 1 and 2 (HSV-1, HSV-2), Varicella Zoster virus (VZV), Epstein-Barr virus (EBV), human cytomegalovirus (HCMV), human herpesvirus type 6, type 7 and type

2. Early HHV-6 replication is associated with morbidity non-related to CMV infection after kidney transplantation
Human herpesvirus type 6-(HHV-6) has been associated with morbidity after liver transplantation. OBJECTIVE: The aim of this study was to determine the HHV-6 seroprevalence among donor-recipient pairs, analyze the incidence of early active infection, its clinical manifestation, interaction with CMV, and the related morbidity in the first year after kidney tra

3. Antiviral activity of the Lippia graveolens (Mexican oregano) essential oil and its main compound carvacrol against human and animal viruses
Mexican oregano (Lippia graveolens) is a plant found in Mexico and Central America that is traditionally used as a medicinal herb. In the present study, we investigated the antiviral activity of the essential oil of Mexican oregano and its major component, carvacrol, against different human and animal viruses. The MTT test (3-4,5-dimethythiazol-2yl)-2,5-diph

4. Infecção pelo herpesvírus 8 humano (HHV-8) em populações indígenas e não indígenas da Amazônia brasileira / Human herpesvirus-8 infection in amerindian and non-amerindian populations in the brazilian Amazon region
Human herpes virus type 8 (HHV-8) is hyperendemic in Amerindian populations, but its modes of transmission are unknown. Objectives: 1. Study the Human Herpesvirus-8 Infection and Oral Shedding in Amerindian and Non-Amerindian Populations in the Brazilian Amazon Region. 2. Methods: Antibodies against either HHV-8 latency-associated nuclear antigen (LANA) or H

5. Burkitt lymphoma: clinicopathologic, immunohistochemical and association with Epstein-Barr virus (EBV) in adult and pediatric population in different geographical regions of Brazil / Linfoma de Burkitt: características clinicopatológicas, imunoistoquímicas e associação com o vírus de Epstein-Barr (EBV) em populações adulta e pediátrica em diferentes regiões geográficas no Brasil
Burkitt lymphoma (BL) is a high grade B cell lymphoma with a consistent translocation involving the proto-oncogene C-MYC. The association with the Epstein-Barr virus (EBV) varies depending on the clinicopathological form. This study aims to analyze the clinicopathologic, immunohistochemical features, including the expression of transcription factor MUM1/IRF4

6. Avaliação da resposta tecidual "in situ" do fenótipo, da expressão de HHV-8/LANA e de citocinas em lesões cutâneas de sarcoma de Kaposi clássico e sarcoma de Kaposi associado à AIDS na era pré e pós-terapia anti-retroviral combinada / Evaluation of tissue response "in situ" of the phenotype, expression of HHV-8/LANA and cytokines in cutaneous lesions of classic Kaposi sarcoma and AIDS associated Kaposi sarcoma in the pre-and post- highly active antiretroviral therapy era
Kaposis sarcoma (KS) is a vascular-originated tumor associated to human herpesvirus 8 (HHV-8). The incidence of AIDS-KS has decreased after the advent of highly active antiretroviral therapy (HAART), without studies regarding cutaneous inflammatory response and HHV-8 expression in pre- and post-HAART era. We used immunohistochemistry to characterize and to q

7. Kaposi's sarcoma-associated herpesvirus infection and Kaposi's sarcoma in Brazil
Kaposi's sarcoma (KS) became a critical health issue with the emergence of acquired immunodeficiency syndrome (AIDS) in the 1980s. Four clinical-epidemiological forms of KS have been described: classical KS, endemic KS, iatrogenic KS, and AIDS-associated KS. In 1994, Kaposi's sarcoma-associated herpesvirus (KSHV) or human herpesvirus type 8 was identified by

8. Detection of herpersvirus type 8 (HHV8) in children s tonsils and adenoids by immunohistochemistry and in situ hybridization / Pesquisa do herpesvirus tipo 8 (HHV8) em adenoides e tonsilas de crianças : um estudo imunoistoquimico e por hibridização "in situ"
Objective: Human herpesvirus 8 (HHV8) has been associated with multicentric Castieman s disease, Kaposi s sarcoma and effusion non-Hodgkin s lymphoma. Epidemiological studies have shown seropositivity in variable proportions of populations. It seems to be sexually transmitted among adults and through oral contact among children. The virus has been demonstrat

9. Soroprevalencia e epidemiologia molecular do herpesvirus humano 8 (HHV-8) em populações brasileiras
CHANG et al first identified human Herpesvirus Type 8 (HHV-8) in 1994 from skin biopsies of patients with Acquired Immunodeficiency Syndrome (AIDS) associated Kaposi?s Sarcoma (KS). HHV-8 is an oncovirus from the Herpesviridae family, Gamaherpesvirinae subfamily and Rhadinovirus genus. It is the only one of its genus to infect humans. Its ultra structure rem

Desde a descoberta do herpes vírus humano tipo 8 (HHV-8) como o agente etiológico do sarcoma de Kaposi (SK) nas suas diferentes formas clínico-epidemiológicas, vários estudos vêm sendo conduzidos com o intuito de determinar as vias de transmissão desse vírus em populações endêmicas e de risco epidemiológico. Em regiões endêmicas, a transmissão

12. HHV-8 infection in patients with AIDS-related Kaposi's sarcoma in Brazil
The aims of the present study were to determine the prevalence of human herpesvirus type 8 (HHV-8) in HIV-positive Brazilian patients with (HIV+/KS+) and without Kaposi's sarcoma (HIV+/KS-) using PCR and immunofluorescence assays, to assess its association with KS disease, to evaluate the performance of these tests in detecting HHV-8 infection, and to invest
