13. Atividade antiviral da quercetina sobre alguns vírus de importância veterinária / Antiviral activity of the quercetin against important virus of veterinary medicine
The search for new substances with potential antimicrobials is growing and is necessary due, mainly, to the development of resistance of infectious agents to the current drugs. Natural compounds, among them flavonoids, have been a particularly rich source of these antimicrobial agents. The objective of this work was to evaluate the antiviral potential of fla

14. Prevalência de anticorpos contra os vírus da influenza, da arterite viral e herpesvírus em eqüinos do Estado do Rio Grande do Sul, Brasil
O presente estudo teve como objetivo determinar a prevalência de anticorpos contra os vírus da influenza (EIV), da arterite viral (EVAV) e herpesvírus (EHV) em eqüinos no Estado do Rio Grande do Sul (RS), Brasil. Amostras de soro provenientes de eqüinos de 65 municípios do Estado foram submetidas ao teste de inibição da hemaglutinação (HI) para a p

15. Characterization of Brazilian isolates of equine herpesvirus type A / Caracterização genomica de isolados brasileiros do herpesvirus equino do tipo 1
Equine Herpesvirus Type 1 (EHV-1) is a member of Alphaherpesvirinae subfamily implicated with abortions, respiratory and neurological disturbs in horses. The principal mode of viral transmission is through close contact virus-containing secretions of infected horses. Systemic pathogenesis in which this virus is implicated combines primary respiratory infecti

16. Avaliação da função dos macrófagos alveolares após infecção experimental em cavalos por herpesvírus eqüino tipo 1
O papel dos macrófagos alveolares (MA) nos mecanismos de defesa pulmonar foi estudado em cavalos infectados pelo herpesvírus eqüino tipo 1 (EHV-1). Cinco cavalos adultos foram inoculados com 10(6,6) TCID50 do EHV-1, por instilação intranasal. A citologia do lavado broncoalveolar (LBA) foi feita usando-se citocentrifugação das amostras e confecção de

17. Uso de um sistema de ELISA para detecção de anticorpos contra herpesvírus eqüino 1 (HVE-1) em éguas gestantes assintomáticas e potros recém-nascidos
Um sistema de ELISA foi utilizado para se estudar a prevalência do herpesvirus eqüino 1 (HVE-1) em plantéis de cavalos brasileiros vacinados e não vacinados. Amostras de soros foram coletadas de éguas gestantes assintomáticas, antes e após o parto e de seus respectivos potros recém-nascidos. O antígeno foi preparado de uma fração viral purificada

18. Genetic relatedness and colinearity of genomes of equine herpesvirus types 1 and 3.
The arrangement and location of homologous DNA sequences within the genomes of equine herpesvirus type 1 (EHV-1) and EHV-3 were investigated by using Southern blot hybridization analyses conducted under stringent conditions. Recombinant plasmid libraries comprising 95 and 84% of the EHV-1 and EHV-3 genomes, respectively, were labeled with 32P-deoxynucleotide

19. Genetic relatedness of the genomes of equine herpesvirus types 1, 2, and 3.
Genomic DNAs of equine herpesvirus type 1 (EHV-1), EHV-2 (equine cytomegalovirus), and EHV-3 were examined by reassociation kinetic and thermal denaturation analyses to determine the extent and degree of homology among the three viral DNAs. Results of reassociation analyses indicated a limited homology among the three EHV genomes. Homologous DNA sequences eq

20. Genetic relatedness of equine herpesvirus types 1 and 3.
The genetic relatedness of two types of equine herpesviruses (EHVs), 1 (EHV-1) and 3 (EHV-3), was determined by DNA-DNA reassociation kinetics. Denatured, labeled viral DNA probe was allowed to reassociate in the presence or absence of the second unlabeled viral DNA. The initial rate of reassociation of either labeled viral DNA was increased by the presence

21. Use of lambda gt11 and monoclonal antibodies to map the genes for the six major glycoproteins of equine herpesvirus 1.
To localize the genes for the major glycoproteins of equine herpesvirus 1 (EHV-1), a library of the EHV-1 genome was constructed in the lambda gt11 expression vector. Recombinant bacteriophage expressing EHV-1 glycoprotein epitopes as fusion products with beta-galactosidase were detected by immunoscreening with monoclonal antibodies specific for each of six

22. Coexpression by vaccinia virus recombinants of equine herpesvirus 1 glycoproteins gp13 and gp14 results in potentiated immunity.
The equine herpesvirus 1 glycoprotein 14 (EHV-1 gp14) gene was cloned, sequenced, and expressed by vaccinia virus recombinants. Recombinant virus vP613 elicited the production of EHV-1-neutralizing antibodies in guinea pigs and was effective in protecting hamsters from subsequent lethal EHV-1 challenge. Coexpression of EHV-1 gp14 in vaccinia virus recombinan

23. Epitopes of glycoprotein G of equine herpesviruses 4 and 1 located near the C termini elicit type-specific antibody responses in the natural host.
Specific serological diagnosis of equine herpesvirus 4 (EHV4; equine rhinopneumonitis virus) and EHV1 (equine abortion virus) hitherto has not been possible because of extensive antigenic cross-reactivity between these two closely related but distinct viruses. Recently, we identified EHV4 glycoprotein G (gG) and characterized it as a type-specific, secreted

24. Expression of equine herpesvirus 1 glycoprotein D by using a recombinant baculovirus.
Glycoprotein D (gD) of equine herpesvirus 1 (EHV-1) was expressed at the surface of insect cells infected by a recombinant baculovirus. EHV-1 gD was detected as multiple forms (56, 52, and 48 kDa) from 18 to 96 h postinfection. Laboratory animals inoculated with the recombinant EHV-1 gD developed neutralizing antibody responses against both EHV-1 and EHV-4.
