1. Human metapneumovirus in Southern Brazil
Abstract INTRODUCTION Infections caused by respiratory viruses are important problems worldwide, especially in children. Human metapneumovirus (hMPV) is a respiratory pathogen and causes severe infections with nonspecific symptoms. This study reports the hMPV occurrence and dissemination in southern Brazil and compares the frequency of occurrence of this v

2. In silico analysis of amino acid variation in human respiratory syncytial virus: insights into immunodiagnostics
BACKGROUND The highly contagious nature of human respiratory syncytial virus (HRSV) and the gravity of its infection in newborns and vulnerable adults pose a serious public health problem. Thus, a rapid and sensitive diagnostic test for viral detection that can be implemented upon the first appearance of symptoms is needed. The genetic variation of the vir

3. Parainfluenza virus as a cause of acute respiratory infection in hospitalized childrens
Background: Human parainfluenza viruses account for a significant proportion of lower respiratory tract infections in children.Objective: To assess the prevalence of Human parainfluenza viruses as a cause of acute respiratory infection and to compare clinical data for this infection against those of the human respiratory syncytial virus.Methods: A prospecti

4. Genetic variability in G2 and F2 region between biological clones of human respiratory syncytial virus with or without host immune selection pressure
Human respiratory syncytial virus (HRSV) is an important respiratory pathogens among children between zero-five years old. Host immunity and viral genetic variability are important factors that can make vaccine production difficult. In this work, differences between biological clones of HRSV were detected in clinical samples in the absence and presence of se

5. A survey strategy for human respiratory syncytial virus detection among haematopoietic stem cell transplant patients: epidemiological and methodological analysis
Human respiratory syncytial virus (HRSV) causes severe infections among children and immunocompromised patients. We compared HRSV infections among Haematopoietic Stem Cell Transplant program (HSCT) patients and children using direct immunofluorescence (DFA), point-of-care RSV Bio Easy® and a polymerase chain reaction (PCR) assay. Overall, 102 samples from H

6. Seasonality of viral respiratory infections in Southeast of Brazil: the influence of temperature and air humidity
Viruses are the major cause of lower respiratory tract infections in childhood and the main viruses involved are Human Respiratory Syncytial Virus (HRSV), Human Metapneumovirus (HMPV), Influenzavirus A and B (FLUA and FLUB), Human Parainfluenza Virus 1, 2 and 3 (HPIV1, 2 and 3) and Human Rhinovirus (HRV). The purposes of this study were to detect respiratory

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. Structural analysis of human respiratory syncytial virus P protein: identification of intrinsically disordered domains
Human Respiratory Syncytial Virus P protein plus the viral RNA, N and L viral proteins, constitute the viral replication complex. In this report we describe that HRSV P protein has putative intrinsically disordered domains predicted by in silico methods. These two domains, located at the amino and caboxi terminus, were identified by mass spectrometry analysi

9. Caracterização molecular de Vírus Respiratório Sincicial Humano (HRSV) isolados na cidade de São Paulo no período de 2007 a 2008. / Characterization and epidemiologic of Human Respiratory Syncytial Virus (HRSV) isolated in São Paulo city in 2007-2008.
Human Respiratory Syncytial Virus (HRSV) is considered the most common cause of lower respiratory tract disease in infants and young children and are the main guilty for the elevated children hospitalizations rate under 5 years of age. The HRSV has a world-wide distribution, being able to attack all the ages however the 6 weeks to 9 months children of are th

10. Duplex-PCR assay for the detection of adenovirus and respiratory syncytial virus in nasopharyngeal samples
Human adenovirus (HAdV) and human respiratory syncytial virus (HRSV) are important etiologic agents of acute respiratory infections. In this study, a duplex polymerase chain reaction (PCR) assay was developed for the simultaneous detection of HAdV and HRSV in clinical samples. Sixty previously screened nasopharyngeal aspirates were used: 20 HAdV-positive, 20

11. Quasispecies detection in human respiratory syncytial virus (HRSV) samples in absence and presence of polyclonal serum / Detecção de quasispecies em amostras de vírus respiratório sincicial humano (HSRV) na ausência e na presença de soros policlonais
Human respiratory syncytial virus (HRSV) is one of the most important clinical respiratory pathogens, since 64 millions children in the world are infected by this agent every year. Host immunity and viral genetic variability are important factors to a vaccine development, besides quasispecies presence in the viral population. In this work, HRSV quasispecies

12. Expression of human respiratory syncytial virus N and P proteins: functional and immunization studies. / Expressão das proteínas N e P do vírus respiratório sincicial humano: estudos funcionais e de imunização.
The Human Respiratory Syncytial Virus is a single stranded negative RNA enveloped virus and it is considered the most important pathogen of the respiratory tract of infants and neonates. The viral N and P proteins were expressed in bacteria, purified and used for the production of polyclonal antibodies in mice. In silico studies allowed the prediction of int
