1. Reconstrução ligamentar da membrana interóssea do antebraço, no tratamento da instabilidade da articulação radioulnar distal
RESUMO: As infecções por pestivírus são importantes nas indústrias pecuárias, com infecções em bovinos, ovinos e suínos. O gênero Pestivirus da família Flaviviridae inclui quatro espécies reconhecidas: vírus da diarreia viral bovina 1 (BVDV-1), vírus da diarreia viral bovina 2 (BVDV-2), vírus da doença de fronteira (VDF) e vírus da peste su�

3. Estudo transversal para estimar a frequência de anticorpos anti-vírus da diarreia viral bovina-1 em suínos domésticos da região de Mossoró, no estado do Rio Grande do Norte, Brasil
RESUMO: Este estudo investigou a ocorrência de anticorpos contra o BVDV-1 em rebanhos suínos localizados na região da cidade de Mossoró do Estado do Rio Grande do Norte, Brasil. Um tamanho de amostra de 412 animais foi estimado assumindo uma prevalência desconhecida (fixada em 50%). O teste de virusneutralização foi utilizado para detectar a presenç

4. Classical swine fever virus: recovery of infectious viruses from cDNA constructs and generation of recombinant cytopathogenic defective interfering particles.
The 5'- and 3'-terminal sequences of the genomic RNA from classical swine fever virus (CSFV) were determined, and the resulting information was used for construction of full-length CSFV cDNA clones. After transfection of in vitro-transcribed RNA derived from a cDNA construct, infectious CSFV was recovered from porcine cells. To confirm the de novo generation

5. Classical Swine Fever Virus Interferes with Cellular Antiviral Defense: Evidence for a Novel Function of Npro
Classical swine fever virus (CSFV) replicates efficiently in cell lines and monocytic cells, including macrophages (MΦ), without causing a cytopathic effect or inducing interferon (IFN) secretion. In the present study, the capacity of CSFV to interfere with cellular antiviral activity was investigated. When the porcine kidney cell line SK-6 was infected wit

6. Classical swine fever virus: independent induction of protective immunity by two structural glycoproteins.
To study which proteins of classical swine fever virus (CSFV) are able to confer protective immunity in swine, N-terminal autoprotease, viral core protein, and the three structural glycoproteins were expressed via vaccinia virus recombinants (VVR). CSFV proteins synthesized in cells infected with VVR showed migration characteristics on sodium dodecyl sulfate

7. Internal entry of ribosomes is directed by the 5' noncoding region of classical swine fever virus and is dependent on the presence of an RNA pseudoknot upstream of the initiation codon.
Bicistronic RNAs containing the 373-nucleotide-long 5' nontranslated region (NTR) of the classical swine fever virus (CSFV) genome as intercistronic spacer were used to show the presence of an internal ribosome entry site (IRES) in the 5' end of the CSFV genome. By coexpression of the poliovirus 2A protease it was demonstrated that the CSFV 5' NTR-driven tra

8. Diagnostic Evaluation of a Real-Time Reverse Transcriptase PCR Assay for Detection of Classical Swine Fever Virus
A fluorogenic-probe hydrolysis (TaqMan)-reverse transcriptase (RT) PCR for classical swine fever virus (CSFV) was evaluated for diagnostic sensitivity and specificity by using clinical samples obtained from the Dominican Republic, where the disease is enzootic. The sensitivity of this test, using nasal swab samples taken from both symptomatic and asymptomati

9. Nucleotide sequence of classical swine fever virus strain Alfort/187 and transcription of infectious RNA from stably cloned full-length cDNA.
The complete nucleotide sequence of the genome of classical swine fever virus (CSFV) strain Alfort/187 was determined from three cDNA libraries constructed by cloning of DNA fragments obtained from independent sets of reverse transcription and PCR. The cDNA fragments were then assembled and inserted downstream of a T7 promoter in a P15A-derived plasmid vecto

10. Classical Swine Fever Virus Erns Deletion Mutants: trans-Complementation and Potential Use as Nontransmissible, Modified, Live-Attenuated Marker Vaccines
An SK6 cell line (SK6c26) which constitutively expressed the glycoprotein Erns of classical swine fever virus (CSFV) was used to rescue CSFV Erns deletion mutants based on the infectious copy of CSFV strain C. The biochemical properties of Erns from this cell line were indistinguishable from those of CSFV Erns. Two Erns deletion mutants were constructed, vir

11. Specific Interaction of Eukaryotic Translation Initiation Factor 3 with the 5′ Nontranslated Regions of Hepatitis C Virus and Classical Swine Fever Virus RNAs
Translation of hepatitis C virus (HCV) and classical swine fever virus (CSFV) RNAs is initiated by cap-independent attachment (internal entry) of ribosomes to the ∼350-nucleotide internal ribosomal entry segment (IRES) at the 5′ end of both RNAs. Eukaryotic initiation factor 3 (eIF3) binds specifically to HCV and CSFV IRESs and plays an essential role in

12. Deletions of Structural Glycoprotein E2 of Classical Swine Fever Virus Strain Alfort/187 Resolve a Linear Epitope of Monoclonal Antibody WH303 and the Minimal N-Terminal Domain Essential for Binding Immunoglobulin G Antibodies of a Pig Hyperimmune Serum
The major structural glycoprotein E2 of classical swine fever virus (CSFV) is responsible for eliciting neutralizing antibodies and conferring protective immunity. The current structural model of this protein predicts its surface-exposed region at the N terminus with a short stretch of the C-terminal residues spanning the membrane envelope. In this study, th
