1. Rhinovirus as the main co-circulating virus during the COVID-19 pandemic in children
Abstract Objective: Changes in the epidemiology of respiratory infections during the restrictions imposed as a response to the coronavirus disease 2019 (COVID-19) pandemic have been reported elsewhere. The present study’s aim was to describe the prevalence of a large array of respiratory pathogens in symptomatic children and adolescents during the pandemi

2. 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

3. Detection of avian metapneumovirus subtype A from wild birds in the State of São Paulo, Brazil
RESUMO: O presente estudo investigou a circulação de metapneumovírus aviário em aves silvestres no Brasil. Para tanto, 131 amostras de 366 suabes orofaringeanos ou cloacais coletados de 18 espécies de aves foram testadas individualmente ou na forma de pools por RT-PCR. As amostras detectadas por RT-PCR foram selecionadas para sequenciamento. Treze (9,9%

4. 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

5. 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

7. 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

8. In vitro Anti-HMPV Activity of New Synthetic Phenytoin Derivatives
New derivatives of synthetic 5,5-diphenylhydantoin (phenytoin) were prepared by N-alkylation with 1,3-dibromopropane. Subsequent treatment with sodium azide led to the respective azide. Reaction of the azide with phenylacetylene and 2-hydroxy-3-butyne and oxidation of the resulting alcohol with MnO2 resulted in three triazolic compounds that were evaluated i

9. Performance of direct immunofluorescence assay for the detection of human metapneumovirus under clinical laboratory settings
ABSTRACT INTRODUCTION: Human metapneumovirus (hMPV) is an emergent human respiratory pathogen. This study aimed to evaluate the performance of direct immunofluorescence (DIF) to detect hMPV in a clinical laboratory setting. METHODS: Nasopharyngeal aspirate samples (448) of children and adults with respiratory illness were used to detect hMPV by using DIF

10. In-Vitro Antiviral Activities of Extracts of Plants of The Brazilian Cerrado against the Avian Metapneumovirus (aMPV)
ABSTRACTAvian metapneumovirus (aMPV) is a negative-sense single-stranded RNA enveloped virus of the Metapneumovirus genus belonging to theParamyxoviridae family. This virus may cause significant economic losses to the poultry industry, despite vaccination, which is the main tool for controlling and preventing aMPV. The aim of this study was to evaluate the a

11. 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

12. Infecções respiratórias virais agudas em pacientes pediátricos com câncer em tratamento quimioterápico
OBJETIVO: estimar a prevalência da infecção pelos vírus respiratórios em pacientes pediátricos com câncer e infecção respiratória aguda (IRA) e/ou febre. MÉTODOS: estudo transversal, de janeiro de 2011 a dezembro de 2012. Foram analisadas secreções de aspirado da nasofaringe de menores de 21 anos, com quadro respiratório agudo, atendidos
