1. 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

2. Antiviral activity of the Lippia graveolens (Mexican oregano) essential oil and its main compound carvacrol against human and animal viruses
Mexican oregano (Lippia graveolens) is a plant found in Mexico and Central America that is traditionally used as a medicinal herb. In the present study, we investigated the antiviral activity of the essential oil of Mexican oregano and its major component, carvacrol, against different human and animal viruses. The MTT test (3-4,5-dimethythiazol-2yl)-2,5-diph

3. Avaliação in vitro da atividade antiviral de extratos de plantas frente ao metapneumovirus aviário (AMPV) e vírus respiratório sincicial bovino (BRSV) / In vitro evaluation of antiviral activity of plants extract against avian metapneumovirus (AMPV) and bovine respiratory syncytial virus (BRSV)
Para avaliar a atividade antiviral dos extratos de plantas brasileiras foram eleitos o Metapneumovirus aviário (aMPV) e o vírus Respiratório sincicial bovino (BRSV) pertences à família Paramyxoviridae, subfamília Pneumovirinae, gêneros Metapneumovirus e Pneumovirus respectivamente. Tanto o aMPV quanto o BRSV são vírus semelhantes aos que causam doen

4. Analise filogenetica de isolados autoctones do virus respiratorio sincicial bovino (BRSV) e aprimoramento de um modelo experimental em camundongos / Phylogenetic analysis of authochtonous bovine respiratory syncytial virus isolates and improvement of an experimental model of infection in mice
O Vírus Respiratório Sincicial Bovino (BRSV) é uma causa importante de doença respiratória em bovinos. O BRSV é um membro da família Paramyxoviridae, subfamília Pneumovirinae, pertencendo ao gênero Pneumovirus. Nos últimos quinze anos, evidências sorológicas e de isolamento do vírus revelaram que o BRSV está circulando no Brasil, causando doen�

5. Detecção, isolamento e caracterização molecular parcial de virus respiratorio sincicial bovino (BRSV) em amostras de campo / Detection, isolation and molecular characterization of bovine respiratory syncytial virus (BRSV) in field samples
No presente estudo, técnicas para a detecção do vírus respiratório sincicial bovino, BRSV, visando ao diagnóstico e caracterização molecular deste patógeno, foram adaptadas e aplicadas em amostras coletadas de animais sem levar em consideração a presença de sinais e sintomas clínicos característicos de infecções causadas por esse agente. Foi

6. Adaptação e comparação das tecnicas de RT-nested-PCR e imuno-histoquimica no diagnostico do virus respiratorio sincicial bovino (BRSV)
Bovine respiratory syncytial virus (BRSV) is the etiologic agent of widely distributed respiratory infections and is responsible for significant economic losses in commercial cattle production. Infection by BRSV produces pathological changes such as bronchiolitis and interstitial pneumonia and affects mainly young animals. The poor growth of the virus in cel

7. Characterization of bovine respiratory syncytial virus isolated in Brazil
This paper presents the first isolation of bovine respiratory syncytial virus in Brazil and its physicochemical, morphological and molecular characterization. The virus was isolated from 33 samples of nasotracheal secretions, successively inoculated into a Madin-Darby bovine kidney cell culture, which was characterized by physicochemical tests and morphologi

8. Caracterização molecular de virus respiratorio sincicial bovino (BRSV) isolado no Brasil
The bovine respiratory syncytial virus (BRSV) causes acute infection in the respiratory tract of cattle and is wide spread in the world, causing significant economic losses. The objective of this project was to characterize the BRSV, named BRSV-25-BR, isolated from a 2 months calve from Rio Grande do Sul state cattle, which presented respiratory disease symp

9. Antiviral effects of bovine interferons on bovine respiratory tract viruses.
The antiviral effects of bovine interferons on the replication of bovine respiratory tract viruses were studied. Bovine turbinate monolayer cultures were treated with bovine interferons and challenged with several bovine herpesvirus 1 strains, bovine viral diarrhea virus, parainfluenza type 3 virus, goat respiratory syncytial virus, bovine respiratory syncyt

10. 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

11. Detection of antibody to bovine syncytial virus and respiratory syncytial virus in bovine fetal serum.
Batches of commercial fetal bovine serum, described by the suppliers as antibody-free, all contained antibody to bovine syncytial virus (BSV) when tested by indirect immunofluorescence. Antibody to bovine respiratory syncytial virus (RSV) was not detected in these sera. Twenty-four percent of individual fetal bovine sera contained antibody to BSV, and 14% co

12. Monoclonal antibodies to the fusion protein of bovine respiratory syncytial virus.
Five monoclonal antibodies specific for bovine respiratory syncytial virus were characterized by Western immunoblotting, radioimmunoprecipitation, and epitope mapping assays. The monoclonal antibodies were found to be specific for the fusion protein, and there were at least two antigen binding sites, one of which was neutralizing.
