1. Influenza Sentinel Surveillance and Severe Acute Respiratory Infection in a Reference Hospital in Southern Brazil
Abstract INTRODUCTION: We report the results of the active surveillance of influenza infections in hospitalized patients and the evaluation of the seasonality and correlation with temperature and rainfall data. METHODS: During the 2-year study period, 775 patients were tested for 15 respiratory viruses (RVs). RESULTS: Most of the 57% of (n=444) virus-po

2. ANTICORPOS POLICLONAIS PARA O IMUNODIAGNÓSTICO DE VÍRUS BOVINO
Resumo O objetivo do estudo foi produzir anticorpos policlonais para vírus bovino e testar a reatividade em imunoensaios como imunofluorescência, imunoperoxidase e slot blot. Como imunógeno utilizou-se cepas e/ou isolados dos herpesvírus bovino tipo 1, 2 e 5 (BoHV-1, BoHV-2 e BoHV-5), vírus da diarreia viral bovina (BVDV), vírus respiratório sincicial

3. 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

4. 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

5. Prevalence of rhinovirus in wheezing children: a comparison with respiratory syncytial virus wheezing
Abstract Objective To explore the distribution and clinical manifestations of rhinovirus infection in wheezing children, and compare the clinical differences between rhinovirus- and respiratory syncytial virus-induced wheezing. Materials and methods This prospective cohort study was carried out in Children's Hospital of Soochow University from Dec 2012 to

6. Viral aetiology of common colds of outpatient children at primary care level and the use of antibiotics
Although antibiotics are ineffective against viral respiratory infections, studies have shown high rates of prescriptions worldwide. We conducted a study in Brazil to determine the viral aetiologies of common colds in children and to describe the use of antibiotics for these patients. Children up to 12 years with common colds were enrolled from March 2008-Fe

7. 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

8. 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

9. Immunohistochemical detection of virus through its nuclear cytopathic effect in idiopathic interstitial pneumonia other than acute exacerbation
Idiopathic interstitial pneumonias include complex diseases that have a strong interaction between genetic makeup and environmental factors. However, in many cases, no infectious agent can be demonstrated, and these clinical diseases rapidly progress to death. Theoretically, idiopathic interstitial pneumonias could be caused by the Epstein-Barr virus, cytome

10. Sentinel surveillance of influenza and other respiratory viruses, Brazil, 2000-2010
There are scanty data on the epidemiology of influenza and other respiratory viruses in South America and Brazil. The aim of this study was to summarize the data from the Brazilian surveillance system of influenza and other respiratory viruses and discuss the patterns of viral circulation. The system is based on detecting cases of influenza-like illness in s

11. 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

12. Comparison of laboratory tests for detection of virusesRespiratory Syncytial Virus (HRSV) in clinical samples outpatient children and adults with bone marrow transplantation suspicion of acute respiratory infection treated at the Hospital São Paulo. / Comparação de testes laboratoriais para detecção de Vírus Respiratório Sincicial Humano (VRSH) em amostras clínicas de crianças ambulatoriais e adultos transplantados de medula óssea com suspeita de infecção respiratória aguda atendidos no Hospital São Paulo.
O Vírus Respiratório Sincicial Humano (VRSH) é considerado o principal causador de infecções do trato respiratório inferior, principalmente bronquiolite e pneumonia em crianças e recém nascidos, e tem se mostrado também um importante agente de infecção respiratória aguda em imunocomprometidos. Há uma grande variedade de técnicas disponíveis pa
