1. Isolamento do vírus Parainfluenza bovino tipo 3 no Rio Grande do Sul, Brasil : relato de caso / Isolation of bovine Parainfluenza virus type 3 in Rio Grande do Sul, Brazil
É descrito o isolamento do vírus Parainfluenza bovino tipo 3 (bPI-3) a partir de secreções nasais coletadas de um bovino com infecção respiratória. A identificação do agente foi realizada através de isolamento em cultivo celular e confirmada por testes de hemaglutinação, inibição da hemaglutinação, hemadsorção e imunofluorescência direta.

2. RT-PCR for detection on bovine parainfluenza virus type 3 (bPIV-3) = RT-PCR para detecção do vírus parainfluenza bovino tipo 3 (bPIV-3) / RT-PCR para detecção do vírus parainfluenza bovino tipo 3 (bPIV-3)
A técnica de RT-PCR tem sido freqüentemente utilizada para a detecção do vírus parainfluenza humano tipo 3 (hPIV- 3), mas a literatura é escassa em relação ao vírus parainfluenza bovino tipo 3 (bPIV-3) .O objetivo deste trabalho foi descrever uma técnica de reação em cadeia pela polimerase, precedida de transcrição reversa (RT-PCR), para a dete

3. Desenvolvimento de técnicas de RT-PCR para seqënciamento do gene da hemaglutinina-neuraminidase (HN) e detecção do vírus Parainfluenza bovino tipo 3 / Development of RT-PCR techniques for hemagglutinin-neuraminidase (HN) gene sequencing and detection of bovine type 3 Parainfluenza virus
Existem diversos trabalhos publicados sobre a utilização de diferentes métodos imunológicos para diagnosticar infecções do trato respiratório causadas por vírus parainfluenza bovino tipo 3 (bPIV-3). Entretanto, é escassa a literatura sobre a utilização da técnica de isolamento viral. Até o presente momento não havia sido relatada a utilização

4. Protection from parainfluenza-3 virus and persistence of infectious bovine rhinotracheitis virus in sheep vaccinated with a modified live IBR-PI-3 vaccine.
Ewes (N = 7) and their lambs (N = 12) were vaccinated with a commercial modified live infectious bovine rhinotracheitis-parainfluenza type 3 virus vaccine. Both the vaccinated ewes and lambs and a group of unvaccinated ewes (N = 8) and their lambs (N = 13) were subsequently challenged with virulent parainfluenza type 3 virus. Although absolute immunity to in

5. Lack of Virus-Specific Bacterial Adherence to Bovine Embryonic Lung Cells Infected with Bovine Parainfluenza Virus Type 3 †
Infection of bovine embryonic lung cells with bovine parainfluenza virus type 3 did not induce in vitro, virus-specific, hemadsorption-related adherence of Corynebacterium pyogenes, Haemophilus somnus, Staphylococcus aureus, Streptococcus zooepidemicus, Pasteurella haemolytica, Listeria monocytogenes, Escherichia coli, Pasteurella multocida, Brucella sp., or

6. Methods for the detection of viruses in bovine serum.
An evaluation of selected commonly used procedures for the recovery of endogenous viral contaminants in bovine serum was undertaken. Low speen centrifugation (25,000 x g) was found to be efficient for the recovery of bovine herpesvirus type 1 (BHV-1) and parainfluenza virus type 3(PI-3) in bovine serum. Decreased infectivity titers were obtained when parainf

7. Serology of bovine parainfluenza virus type 3: comparison of the enzyme linked immunosorbent assay and hemagglutination inhibition.
An enzyme linked immunosorbent assay (ELISA) for the detection of antibody to bovine parainfluenza virus type 3 has been compared with the hemagglutination inhibition test on 130 field sera, and seven other paired sera showing a significant raise of titers. The ELISA was found to be four to 64 times more sensitive than the hemagglutination inhibition test an

8. Expression of the Surface Glycoproteins of Human Parainfluenza Virus Type 3 by Bovine Parainfluenza Virus Type 3, a Novel Attenuated Virus Vaccine Vector
Bovine parainfluenza virus type 3 (bPIV3) is being evaluated as an intranasal vaccine for protection against human PIV3 (hPIV3). In young infants, the bPIV3 vaccine appears to be infectious, attenuated, immunogenic, and genetically stable, which are desirable characteristics for an RNA virus vector. To test the potential of the bPIV3 vaccine strain as a vect

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. Epizootiological survey of parainfluenza-3, reovirus-3, respiratory syncytial and infectious bovine rhinotracheitis viral antibodies in sheep and goat flocks in Quebec.
A serological survey was conducted in an attempt to detect antibodies against bovine respiratory viruses in sheep and goats from seven geographical areas of Quebec. Sera from 10% of the animals in 182 sheep flocks and 40 goat flocks were collected and specific antibodies against parainfluenza-3, reovirus type 3, respiratory syncytial and infectious bovine rh

11. Recombinant type 5 adenoviruses expressing bovine parainfluenza virus type 3 glycoproteins protect Sigmodon hispidus cotton rats from bovine parainfluenza virus type 3 infection.
Cotton rats were used to study the replication and pathogenesis of bovine parainfluenza virus type 3 (bPIV3) and to test the efficacy of the F and HN glycoproteins in modulating infection. In vitro cultures of cotton rat lung cells supported the growth of bPIV3 as shown by virus recovery, immunofluorescence, immunoprecipitation, and syncytium induction. Intr

12. Bovine parainfluenza type 3 virus infection: ultrastructural aspects of viral pathogenesis in the bovine respiratory tract.
After aerosolization of a bovine strain of parainfluenza type 3 virus, the pathogenesis of the virus was followed from the trachea to the bronchioalveolar compartments of the lung of colostrum-free calves and of conventionally reared calves during a 5- to 12-day postexposure interval. By tissue titration, plaque assay, and electron microscopy, it was found t
