1. Description of a human Bocavirus recombinant strain in the Americas
Human bocaviruses (HBoV) are mainly associated with respiratory and gastroenteric infections. These viruses belong to the family Parvoviridae, genus Bocaparvovirus and are classified in four subtypes (HBoV1-4). Recombination and point mutation have been described as basis of parvovirus evolution. In this study three viral sequences were obtained from positiv

2. Human virome in nasopharynx and tracheal secretion samples
BACKGROUND In Brazil the implementation of the Sentinel Surveillance System of Influenza began in 2000. Central public health laboratories use reverse transcription-quantitative polymerase chain reaction (RT-qPCR) for diagnosis of respiratory viruses, but this protocol identifies only specific targets, resulted in inconclusive diagnosis for many samples. T

3. Identification of Human Bocavirus type 4 in a child asymptomatic for respiratory tract infection and acute gastroenteritis - Goiânia, Goiás, Brazil
Abstract Human Bocavirus (HBoV) has been identified from feces and respiratory samples from cases of both acute gastroenteritis and respiratory illness as well as in asymptomatic individuals. The aim of this study was to detect and characterize HBoV from fecal samples collected from hospitalized children aged less than five years old with no symptoms of resp

4. 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

5. 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

6. Human bocavirus 1 and 3 infection in children with acute gastroenteritis in Brazil
To determine the positivity rate of human bocavirus (HBoV) 1 and 3 among children who presented with acute gastroenteritis symptoms during the period of 1994-2004 in the Central-West Region of Brazil, 762 faecal samples were tested using polymerase chain reaction (PCR) for the detection of HBoV DNA. Primers for a segment of the non-structural viral protein 1

7. High prevalence of human bocavirus 1 in infants with lower acute respiratory tract disease in Argentina, 2007 - 2009
Human bocavirus (HBoV) is a parvovirus whose association with respiratory disease is currently under investigation. OBJECTIVE: To determine HBoV prevalence in children with lower acute respiratory infection. METHODS: We investigated HBoV in 433 nasopharyngeal aspirates collected in 2007-2009 from children 0 to 5 years old hospitalized with bronchiolitis or p

8. 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

10. Molecular characterization of viruses associated with gastrointestinal infection in HIV-positive patients
BACKGROUND: Diarrhea is a major cause of morbidity and mortality among HIV-infected patients worldwide. OBJECTIVE: We sought to determine the frequency of viral gastrointestinal infections among Brazilian HIV-infected patients with diarrhea. METHODS: A collection of 90 fecal specimens from HIV-infected individuals with diarrhea, previously tested for the pre

12. Respiratory infections by human bocavirus: molecular and clinical features. / Infecções respiratórias por bocavirus humano: aspectos clínicos e moleculares
O bocavirus humano (HBoV) é um parvovirus recentemente identificado em associação com a presença de sintomas de infecção do trato respiratório. Esse vírus possui um genoma de aproximadamente 5217 nucleotídeos que contém 3 open reading frames que codificam 4 proteínas (NS1, NP-1, VP-1 e VP-2). HBoV tem sido detectado em amostras respiratórias de d
