14. Detection of respiratory viruses by real-time polymerase chain reaction in outpatients with acute respiratory infection
Viruses are the major contributors to the morbidity and mortality of upper and lower acute respiratory infections (ARIs) for all age groups. The aim of this study was to determine the frequencies for a large range of respiratory viruses using a sensitive molecular detection technique in specimens from outpatients of all ages with ARIs. Nasopharyngeal aspirat

15. The rapid and sustained responses of dendritic cells to influenza virus infection in a non-human primate model
Dendritic cells (DCs) are readily infected by influenza viruses and play a crucial role in regulating host innate and adaptive immune responses to viral infection. The aims of this study are to characterize the dynamic changes in the numbers and maturation status of dendritic cells present in the lung and lung-associated lymph nodes (LALNs) in the model of a

17. Influenza A virus infection of healthy piglets in an abattoir in Brazil: animal-human interface and risk for interspecies transmission
Asymptomatic influenza virus infections in pigs are frequent and the lack of measures for controlling viral spread facilitates the circulation of different virus strains between pigs. The goal of this study was to demonstrate the circulation of influenza A virus strains among asymptomatic piglets in an abattoir in Brazil and discuss the potential public heal

18. Profilaxia da infecção por vírus sincicial respiratório: estudo clínico prospectivo de crianças submetidas ao uso de palivizumabe. / Prophylactic treatment of infection by the sincycial respiratory virus: prospective clinical study of infants to the use of palivizumab.
Respiratory Syncytial Virus (RSV) is the most important etiologic agent in acute lower respiratory tract infections (ALRTIs) in children under two years, with high rates of hospitalization and death in high risk children for severe RSV infection. Objective: To identify the virus present in acute respiratory tract infections (ARTIs) and to analyze rates of ho

19. Caracterização genética de rinovírus humano em amostras de populações distintas do Estado de São Paulo. / Human rhinovirus genotyping in samples of distinct populations of São Paulo State, SP, Brazil.
Infections caused by Human Rhinoviruses (HRVs) account for 25%-50% of respiratory illnesses among individuals presenting influenza-like illness (ILI). HRVs could be classified in at least three species: HRV-A, HRV-B, and HRV-C. The HRV-C species has frequently been described among children and apparently has led to severe illness resulting in hospitalization

20. Rinovírus humano em infecções respiratórias agudas em crianças menores de cinco anos de idade: fatores envolvidos no agravamento da doença
Apesar dos rinovírus humanos (HRV) serem mais relacionados com resfriado comum, esses agentes também estão associados com infecções respiratórias graves. Os possíveis fatores que levariam ao agravamento das doenças respiratórias pelos HRV foram investigados neste estudo, assim como a frequência desses vírus. A IFI e/ou RT-PCR foram utilizadas para

22. Epidemiologia e caracterização molecular do vírus da Influenza em quatro espécies de pinguins na Região Antártica. / Epidemiology and molecular characterization of the influenza virus in four penguin species of the antartic region.
Epidemics and pandemics of influenza usually refer to infections in human beings. The influenza virus is not, however, restricted to humans and can cause infirmity and death in other species including horses, swine, marine mammals, birds, and others. Ecological studies of viral infections have led to the hypothesis that the influenza viruses that attack mamm

23. Respiratory virus infections among hospitalized patients with suspected influenza A H1N1 2009 virus during the first pandemic wave in Brazil
INTRODUCTION: During the first pandemic wave of the influenza A H1N1 2009 virus, morbidity was particularly high in Brazil. Hospitalizations resulting from severe respiratory disease due to suspected influenza-like illness created an opportunity to identify other respiratory viruses causing lower respiratory infections. OBJECTIVE: The purpose of this study w

24. Detection of human bocavirus and human metapneumovirus by real-time PCR from patients with respiratory symptoms in Southern Brazil
The introduction of newer molecular methods has led to the discovery of new respiratory viruses, such as human metapneumovirus (hMPV) and human bocavirus (hBoV), in respiratory tract specimens. We have studied the occurrence of hMPV and hBoV in the Porto Alegre (PA) metropolitan area, one of the southernmost cities of Brazil, evaluating children with suspect
