1. Optimisation of a quantitative polymerase chain reaction-based strategy for the detection and quantification of human herpesvirus 6 DNA in patients undergoing allogeneic haematopoietic stem cell transplantation
Human herpesvirus 6 (HHV-6) may cause severe complications after haematopoietic stem cell transplantation (HSCT). Monitoring this virus and providing precise, rapid and early diagnosis of related clinical diseases, constitute essential measures to improve outcomes. A prospective survey on the incidence and clinical features of HHV-6 infections after HSCT has

2. Assessment of immunological changes in Epstein-Barr virus co-infection in Egyptian chronic HCV patients
Epstein-Barr virus (EBV) plays a major role in liver pathology. Similar to other members of the herpesvirus family, EBV establishes a persistent infection in more than 90% of adults. The aim of this study was to evaluate the impact of EBV and chronic hepatitis C co-infection (HCV) on biochemical and immunological responses in patients. The study was conducte

3. Human herpesvirus-6 and cytomegalovirus DNA in liver donor biopsies and their correlation with HLA matches and acute cellular rejection
Herpesvirus reactivation is common after liver transplantation. OBJECTIVE: Analyze the presence of cytomegalovirus (HCMV) and human herpesvirus-6 (HHV-6) DNA in liver donor biopsies, seeking to better understand issues involving human donor leukocyte antigens (HLA)-A, B and DR, as well as correlations with acute cellular rejection. METHODS: Fifty-nine liv

4. 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

5. 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

6. Citomegalovírus, herpesvírus humano 6, herpesvírus humano 7 e perfil imunofenotípico do infiltrado inflamatório na periodontite crônica marginal / Cytomegalovirus, human herpesvirus 6, human herpesvirus 7 and immunophenotypic profile of inflammatory infiltrate in marginal chronic periodontitis
Human chronic periodontitis is an inflammatory process characterized by dense accumulation of immune cells in the periodontal tissue. The periodontitis can lead to loss of teeth in the patient and the pathogenesis of this disease is not completely known. This study tested the hypothesis that cells within inflammatory infiltrate can harbor betaherpesviruses a

7. 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

8. Detection of human herpesvirus 7 infection in young children presenting with exanthema subitum
In this study, we assessed the prevalence of human herpesvirus-7 (HHV-7) in 141 serum samples from children less than four years of age with exanthematic disease. All samples were negative for measles, rubella, dengue fever and parvovirus B19 infection. Testing for the presence of human herpesvirus-6 (HHV-6)-specific high avidity IgG antibodies by indirect i

9. Detection of human herpesvirus 6 and 7 DNA in saliva from healthy adults from Rio de Janeiro, Brazil
In this study, we aimed to evaluate virus shedding in the saliva of healthy adults from the metropolitan region of the city of Rio de Janeiro, Brazil, in order to verify the prevalence of both human herpesviruses 6 and 7 (HHV-6, HHV-7). The studied group comprised 182 healthy individuals at Pedro Ernesto University Hospital, who were being seen for annual od

10. Avaliação da saúde bucal e detecção do vírus HSV-1 e EBV na saliva de pacientes pediátricos antes e depois do transplante renal / Assessment of oral health and detection of HSV-1 and EBV in saliva of pediatric patients before and after renal transplantation
O transplante renal é uma modalidade de tratamento para substituir os órgãos em falência. As manifestações orais mais freqüentes nos pacientes portadores de insuficiência renal crônica (IRC) e transplantados renais (TR) são as alterações do esmalte, as estomatites, gengivites, diminuição do fluxo salivar, hiperplasias gengivais e as infecções

11. First survey for detecting the presence of human herpesvirus 8 infection (HHV-8) in Maputo, Mozambique
Human herpesvirus 8 (HHV-8), the etiological agent of Kaposi's sarcoma (KS), is endemic in parts of the sub-Saharan, and KS has increased concomitantly with the HIV/AIDS epidemic. In Mozambique (MZ), no data concerning HHV-8 infection was available, thus the main of this work was to investigate, for the first time, the presence of HHV-8 infection in Maputo,

12. Estudo epidemiológico da infecção por herpesvírus 8 humano (HHV-8) em população indígena da Amazônia brasileira / Epidemiological study of Human herpesvirus 8 infection (HHV-8) in the Amerindian population from Brazilian Amazon
The human herpesvirus 8 (HHV-8) is endemic in Africa and Amerindian populations from Amazon region. The infection in those populations occurs during childhood and, in Africa, involves a close contact in intrafamilial environment. Several studies confirm the geographical distribution of different subtypes of HHV-8, and the subtype E is typical of the Amerindi
