| [fatal invasive pulmonary aspergillosis triggered by influenza b virus infection in an individual with idiopathic pulmonary fibrosis]. | a 56-year-old man with idiopathic pulmonary fibrosis developed acute symptoms, including fever and cough. chest x-ray and ct scan films revealed consolidations and ground glass opacities in the bilateral lungs suggestive of massive pneumonia and acute respiratory distress syndrome (ards). microscopic examination by a transbronchial lung biopsy from the right middle lobe demonstrated numerous hyphae of aspergillus. despite treatment with anti-fungal agents, respiratory failure rapidly progressed, ... | 2006 | 16617865 |
| bacterial sinusitis and otitis media following influenza virus infection in ferrets. | streptococcus pneumoniae is the leading cause of otitis media, sinusitis, and pneumonia. many of these infections result from antecedent influenza virus infections. in this study we sought to determine whether the frequency and character of secondary pneumococcal infections differed depending on the strain of influenza virus that preceded bacterial challenge. in young ferrets infected with influenza virus and then challenged with pneumococcus, influenza viruses of any subtype increased bacterial ... | 2006 | 16622191 |

| prospects for universal influenza virus vaccine. | the current vaccination strategy against influenza a and b viruses is vulnerable to the unanticipated emergence of epidemic strains that are poorly matched by the vaccine. a vaccine that is less sensitive to the antigenic evolution of the virus would be a major improvement. the general feasibility of this goal is supported by studies in animal models that show that immunologic activities directed against relatively invariant viral determinants can reduce illness and death. the most promising app ... | 2006 | 16704803 |
| identifying influenza viruses with resequencing microarrays. | identification of genetic variations of influenza viruses is essential for epidemic and pandemic outbreak surveillance and determination of vaccine strain selection. in this study, we combined a random amplification strategy with high-density resequencing microarray technology to demonstrate simultaneous detection and sequence-based typing of 25 geographically distributed human influenza virus strains collected in 2004 and 2005. in addition to identification, this method provided primary sequenc ... | 2006 | 16704813 |
| the reappearance of victoria lineage influenza b virus in brazil, antigenic and molecular analysis. | in contrast to influenza a, minor influenza b viruses can co-circulate with the dominant strain during an epidemic allowing the re-emergence of old strains and reassortment between those different strains. the 2001-2002 influenza season in the northern hemisphere was distinguished by the re-emergence of the victoria-lineage viruses, which replaced the yamagata-lineage, after being restricted to east asia throughout the 1990s. | 2006 | 16713335 |
| immune response to influenza vaccination in community-dwelling chinese elderly persons. | we investigated the immune antibody response to influenza vaccine in community-dwelling chinese elderly persons in hong kong. one hundred and twenty-eight subjects were recruited in a single-blind, randomized, and placebo-controlled trial. there was no significant baseline difference between the vaccine and placebo groups regarding the seroprotection rates (pr) (haemagglutination inhibition [hi] titre>or=1:40) and geometric mean titres (gmt) of the hi antibody titers. the pr, gmts and serologica ... | 2006 | 16713661 |

| influenza in children. | excess mortality associated with annual influenza epidemics is highest among persons over 65 y of age, and therefore influenza is often regarded as an illness of the elderly population. ample evidence indicates, however, that the burden of influenza is also substantial in children, and that children have a central role in the spread of influenza in the community during epidemics. vaccination of children against influenza could bring about substantial health benefits not only to children themselv ... | 2006 | 16801171 |

| influenza b viruses isolated in uruguay during the 2002-2005 seasons: genetic relations and vaccine strain match. | monitoring antigenic and genetic variations of circulating influenza viruses is critical for the selection of annual vaccine strains. in order to gain insight into the molecular evolution of influenza b viruses (ibv) isolated in uruguay in 2002 and 2005 outbreaks, antigenic and phylogenetic studies were carried out for the hemagglutinin (ha) gene. antigenic relations among uruguayan and reference strains isolated elsewhere were performed by means of hemagglutination inhibition assays (hai). gene ... | 2007 | 16987563 |
| double-stranded rna binding of influenza b virus nonstructural ns1 protein inhibits protein kinase r but is not essential to antagonize production of alpha/beta interferon. | expression of alpha/beta interferon (ifn-alpha/beta) in virus-infected vertebrate cells is a key event in the establishment of a sustained antiviral response, which is triggered by double-stranded rna (dsrna) produced during viral replication. these antiviral cytokines initiate the expression of cellular proteins with activities that limit the replication and spread of the invading viruses. within this response, the dsrna-dependent protein kinase r (pkr) that is expressed at constitutive levels ... | 2006 | 16987984 |
