1. 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

2. 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

3. 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

4. Bovine Parainfluenza Virus Type 3 (BPIV3) Fusion and Hemagglutinin-Neuraminidase Glycoproteins Make an Important Contribution to the Restricted Replication of BPIV3 in Primates
This study examines the contribution of the fusion (F) and hemagglutinin-neuraminidase (HN) glycoprotein genes of bovine parainfluenza virus type 3 (BPIV3) to its restricted replication in the respiratory tract of nonhuman primates. A chimeric recombinant human parainfluenza type 3 virus (HPIV3) containing BPIV3 F and HN glycoprotein genes in place of its ow

5. A Recombinant Human Parainfluenza Virus Type 3 (PIV3) in Which the Nucleocapsid N Protein Has Been Replaced by That of Bovine PIV3 Is Attenuated in Primates
The shipping fever (SF) and Kansas (Ka) strains of bovine parainfluenza virus type 3 (BPIV3) are restricted in their replication in rhesus monkeys 100- to 1,000-fold compared to human parainfluenza virus type 3 (HPIV3), and the Ka strain also was shown to be attenuated in humans. To initiate an investigation of the genetic basis of the attenuation of BPIV3 i

6. Chimeric Bovine Respiratory Syncytial Virus with Attachment and Fusion Glycoproteins Replaced by Bovine Parainfluenza Virus Type 3 Hemagglutinin-Neuraminidase and Fusion Proteins
Chimeric bovine respiratory syncytial viruses (BRSV) expressing glycoproteins of bovine parainfluenza virus type 3 (BPIV-3) instead of BRSV glycoproteins were generated from cDNA. In the BRSV antigenome cDNA, the open reading frames of the major BRSV glycoproteins, attachment protein G and fusion protein F, were replaced individually or together by those of

7. 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

8. Determinants of the Host Range Restriction of Replication of Bovine Parainfluenza Virus Type 3 in Rhesus Monkeys Are Polygenic
The Kansas strain of bovine parainfluenza virus type 3 (BPIV3) is 100- to 1,000-fold restricted in replication in the respiratory tracts of nonhuman primates compared to human PIV3 (HPIV3), an important pathogen of infants and young children. BPIV3 is also restricted in replication in human infants and children, yet it is immunogenic and is currently being e

9. Recombinant Bovine/Human Parainfluenza Virus Type 3 (B/HPIV3) Expressing the Respiratory Syncytial Virus (RSV) G and F Proteins Can Be Used To Achieve Simultaneous Mucosal Immunization against RSV and HPIV3
Recombinant bovine/human parainfluenza virus type 3 (rB/HPIV3), a recombinant bovine PIV3 (rBPIV3) in which the F and HN genes were replaced with their HPIV3 counterparts, was used to express the major protective antigens of respiratory syncytial virus (RSV) in order to create a bivalent mucosal vaccine against RSV and HPIV3. The attenuation of rB/HPIV3 is p

10. Mucosal Immunization of Rhesus Monkeys against Respiratory Syncytial Virus Subgroups A and B and Human Parainfluenza Virus Type 3 by Using a Live cDNA-Derived Vaccine Based on a Host Range-Attenuated Bovine Parainfluenza Virus Type 3 Vector Backbone
Reverse genetics was used to develop a two-component, trivalent live attenuated vaccine against human parainfluenza virus type 3 (HPIV3) and respiratory syncytial virus (RSV) subgroups A and B. The backbone for each of the two components of this vaccine was the attenuated recombinant bovine/human PIV3 (rB/HPIV3), a recombinant BPIV3 in which the bovine HN an

11. Parainfluenza Virus Type 3 Expressing the Native or Soluble Fusion (F) Protein of Respiratory Syncytial Virus (RSV) Confers Protection from RSV Infection in African Green Monkeys
Respiratory syncytial virus (RSV) causes respiratory disease in young children, the elderly, and immunocompromised individuals, often resulting in hospitalization and/or death. After more than 40 years of research, a Food and Drug Administration-approved vaccine for RSV is still not available. In this study, a chimeric bovine/human (b/h) parainfluenza virus

12. Paramyxovirus mRNA editing leads to G deletions as well as insertions.
Paramyxoviruses are thought to edit their P gene mRNAs co-transcriptionally, by a mechanism in which the polymerase stutters and reads the same template base more than once. Sendai virus (SeV) and bovine parainfluenza virus type 3 (bPIV3) are closely related viruses, but SeV edits its P gene mRNA with the insertion of a single G residue (at approximately 50%
