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. Recurrent wheezing in preterm infants: Prevalence and risk factors,
RESUMO Objetivo: Avaliar a prevalência e os fatores de risco associados à evolução para sibilância recorrente em prematuros. Métodos: O estudo transversal foi feito em 2014 e 2015 e analisou crianças prematuras nascidas entre 2011 e 2012. A busca dessas crianças foi feita em maternidade de hospital universitário e em um Centro de Referência para

3. 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

4. Viral etiology of acute respiratory infections in children in Southern Iran
Abstract INTRODUCTION: Prevalence of influenza A virus (Flu-A), respiratory syncytial virus (RSV), and human metapneumovirus (hMPV) was assessed in children with acute respiratory infections (ARIs). METHODS: Nasopharyngeal aspirates and throat swabs were subjected to real-time polymerase chain reaction (PCR) to detect RSV and Flu-A and to conventional PCR

5. Bronchiolitis Hospitalization in Southern Brazil from 2002 to 2012: A Count Time-series Approach
Abstract INTRODUCTION: Because the antibody neutralizing respiratory syncytial virus (anti-RSV) has a short period of immunization and high cost, the identification of regions and months of highest occurrence of bronchiolitis is very important. METHODS: An Autoregressive Conditional Poisson model was constructed for count data and compared to the standard

6. 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

7. 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

8. 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

9. Respiratory syncytial virus seasonality in Brazil: implications for the immunisation policy for at-risk populations
Respiratory syncytial virus (RSV) infection is the leading cause of hospitalisation for respiratory diseases among children under 5 years old. The aim of this study was to analyse RSV seasonality in the five distinct regions of Brazil using time series analysis (wavelet and Fourier series) of the following indicators: monthly positivity of the immunofluoresc

10. 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

11. 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

12. 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
