2. Profilaxia da infecção por vírus sincicial respiratório: estudo clínico prospectivo de crianças submetidas ao uso de palivizumabe. / Prophylactic treatment of infection by the sincycial respiratory virus: prospective clinical study of infants to the use of palivizumab.
Respiratory Syncytial Virus (RSV) is the most important etiologic agent in acute lower respiratory tract infections (ALRTIs) in children under two years, with high rates of hospitalization and death in high risk children for severe RSV infection. Objective: To identify the virus present in acute respiratory tract infections (ARTIs) and to analyze rates of ho

3. 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

4. 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

6. Caracterização molecular de Vírus Respiratório Sincicial Humano (HRSV) isolados na cidade de São Paulo no período de 2007 a 2008. / Characterization and epidemiologic of Human Respiratory Syncytial Virus (HRSV) isolated in São Paulo city in 2007-2008.
Human Respiratory Syncytial Virus (HRSV) is considered the most common cause of lower respiratory tract disease in infants and young children and are the main guilty for the elevated children hospitalizations rate under 5 years of age. The HRSV has a world-wide distribution, being able to attack all the ages however the 6 weeks to 9 months children of are th

7. Expression of human respiratory syncytial virus N and P proteins: functional and immunization studies. / Expressão das proteínas N e P do vírus respiratório sincicial humano: estudos funcionais e de imunização.
The Human Respiratory Syncytial Virus is a single stranded negative RNA enveloped virus and it is considered the most important pathogen of the respiratory tract of infants and neonates. The viral N and P proteins were expressed in bacteria, purified and used for the production of polyclonal antibodies in mice. In silico studies allowed the prediction of int

8. Genetic variability in the G gene of human respiratory syncytial virus (hRSV) and in the F gene of human metapneuvirus (hMPV) / Variabilidade do gene G do virus repiratorio sicial humano (hRSV) e gene F do metapneumovirus humano (hMPV)
The members of the Paramyxoviridae are enveloped, non-segmented viruses, with negative-sense single stranded genomes. Respiratory syncytial virus (hRSV) is the best characterized agent viral of this group, associated with respiratory diseases in lower respiratory tract. Recently, a new human pathogen belonging to the subfamily Pneumovirinae was identified, t

9. Serological Evidence for the Association of Bovine Respiratory Syncytial Virus with Respiratory Tract Disease in Alabama Cattle 1
A serological investigation for neutralizing antibody to bovine respiratory syncytial virus (BRSV) was conducted using an antigenically related human strain of respiratory syncytial virus. Results demonstrated the effectiveness of the procedure. Sixty-seven percent of healthy, adult cattle tested were found to have antibody to BRSV. Calves in several herds w

10. Topically administered immunoglobulin reduces pulmonary respiratory syncytial virus shedding in owl monkeys.
A human intravenous immunoglobulin preparation containing neutralizing antibodies to respiratory syncytial virus (RSV) was utilized for intratracheal and topical treatment of laboratory-induced RSV infections in owl monkeys (Aotus trivirgatus). Topically administered antibodies induced significant reductions in RSV shedding in the lower respiratory tract.

11. Respiratory syncytial virus infection in mice.
The A2 strain of human respiratory syncytial virus replicated in the nose and lung of BALB/c mice, with virus growing to higher titers in older animals than in younger animals. Virus was recovered from the nose between days 2 and 7 with peak titers on days 3 and 4, and from the lungs between days 2 and 9, with peak titers on days 4 through 6. Serum antibody

12. Human monoclonal Fab fragments derived from a combinatorial library bind to respiratory syncytial virus F glycoprotein and neutralize infectivity.
Respiratory syncytial virus (RSV) is the most important cause, throughout the world, of severe viral lower respiratory tract illness in young children. Antibodies are known to mediate resistance to RSV infection and illness. We have isolated a number of human monoclonal Fab fragments to RSV F glycoprotein from a combinatorial antibody library expressed on th
