1. Isolamento, avaliação do comportamento de amostras de vírus ectima contagioso e melhoramento de técnicas de diagnóstico e de cultivo in vitro.
Ectima contagioso (EC) ou orf é uma doença infecto-contagiosa da pele causada pelo vírus do ectima contagioso (ECV) ou ORFV, que acomete principalmente ovinos e caprinos, e ocasionalmente o homem. Protótipo do gênero Parapoxvírus da família Poxviridae, está amplamente disseminado em todo mundo, inclusive no Brasil, especialmente na Região Nordeste,

2. Vacina experimental produzida em cultivo celular confere proteção parcial contra o ectima contagioso em ovinos
O ectima contagioso (também conhecido como orf), é uma doença debilitante de ovinos e caprinos causada pelo vírus do orf (ORFV). A vacinação tem sido usada com relativo sucesso no controle da doença. No entanto, as vacinas atuais contêm amostras virulentas do agente, são produzidas por escarificação cutânea de animais, e apresentam eficácia ques

3. CARACTERIZAÇÃO DE GENES DO VÍRUS DO ECTIMA CONTAGIOSO ENVOLVIDOS NA REGULAÇÃO DA VIA DE SINALIZAÇÃO DO NF-κB / CHARACTERIZATION OF ORF VIRUS-ENCODED GENES INVOLVED IN THE REGULATION OF THE NF-κB SIGNALING PATHWAY
Orf virus (ORFV), the type member of the genus Parapoxvirus of the family Poxviridae, is the etiologic agent of orf or contagious ecthyma, a contagious and ubiquitous disease of sheep and goats. ORFV genome consists of a double stranded DNA molecule with approximately 138 Kb, and contains 131 putative genes. Among those, 15 are novel genes, unique to parapox

4. INFECÇÃO EXPERIMENTAL DE COELHOS E CAMUNDONGOS COM O VÍRUS DO ECTIMA CONTAGIOSO / EXPERIMENTAL INFECTION OF RABBITS AND MICE WITH CONTAGIOUS ECTHYMA VIRUS
Contagious ecthyma (orf) is a cutaneous disease that affects sheep and goats, and may be occasionally transmitted to humans. The disease is caused by orf virus (ORFV). ORFV infection produces croustous and proliferative lesions, usually on the nostrils and labial commissures of lambs, and also in the udder, teat skin and coronary bands of adults animals. The

5. Sistema de dessalinizaÃÃo por osmose reversa acionado por gerador fotovoltaico com conversor de freqÃÃncia
Uma fraÃÃo importante dos aqÃÃferos da RegiÃo Nordeste do Brasil apresenta Ãgua com nÃveis de salinidade elevados (maior que 3.000 mg.L-1). A populaÃÃo que habita essas regiÃes nÃo conta com suprimento de Ãgua nem de energia elÃtrica convencional, para acionamento de possÃveis sistemas de bombeamento e dessalinizadores. Entretanto, sistemas fot

6. Characterization of a regulatory network that controls sigma B expression in Bacillus subtilis.
The sigB operon of Bacillus subtilis encodes sigma B and three additional open reading frames (orfV, orfW, and orfX). Having previously mapped several mutations that alter the induction pattern of a sigma B-dependent promoter (ctc) to regions of cloned B. subtilis DNA which contain these three open reading frames, we directly tested the regulatory potential

7. Analysis of an orf virus chemokine-binding protein: Shifting ligand specificities among a family of poxvirus viroceptors
We identify a secreted chemokine inhibitor encoded by orf virus (ORFV), the prototypic poxvirus of the Parapoxvirus genus, and show that it is related to the poxvirus type II CC-chemokine-binding proteins (CBP-II) produced by members of the Orthopoxvirus and Leporipoxvirus genera. The ORFV chemokine-binding protein (CBP) is functionally similar to the CBP-II

8. Genomes of the Parapoxviruses Orf Virus and Bovine Papular Stomatitis Virus
Bovine papular stomatitis virus (BPSV) and orf virus (ORFV), members of the genus Parapoxvirus of the Poxviridae, are etiologic agents of worldwide diseases affecting cattle and small ruminants, respectively. Here we report the genomic sequences and comparative analysis of BPSV strain BV-AR02 and ORFV strains OV-SA00, isolated from a goat, and OV-IA82, isola

9. Vascular endothelial growth factor (VEGF)-like protein from orf virus NZ2 binds to VEGFR2 and neuropilin-1
Orf virus, a member of the poxvirus family, produces a pustular dermatitis in sheep, goats, and humans. The lesions induced after infection with orf virus show extensive proliferation of vascular endothelial cells, dilation of blood vessels and dermal swelling. An explanation for the nature of these lesions may lie in the discovery that orf virus encodes an

10. Activation of Bacillus subtilis transcription factor sigma B by a regulatory pathway responsive to stationary-phase signals.
Alternative transcription factor sigma B of Bacillus subtilis controls a stationary-phase regulon induced under growth conditions that do not favor sporulation. Little is known about the metabolic signals and protein factors regulating the activity of sigma B. The operon containing the sigma B structural gene has the gene order orfV-orfW-sigB-rsbX, and opero

11. Novel Recombinant Parapoxvirus Vectors Induce Protective Humoral and Cellular Immunity against Lethal Herpesvirus Challenge Infection in Mice
Orf virus (ORFV; Parapoxvirus ovis) was used to develop a novel vector system for the generation of effective and safe live vaccines. Based on the attenuated ORFV strain D1701-V, recombinants were produced that express the glycoproteins gC (D1701-VrVgC) or gD (D1701-VrVgD) of the alphaherpesvirus of swine, pseudorabies virus (PRV). Expression of gC and gD wa

12. Appearance of the Bona Fide Spiral Tubule of Orf Virus Is Dependent on an Intact 10-Kilodalton Viral Protein
Parapoxviruses can be morphologically distinguished from other poxviruses in conventional negative staining electron microscopy (EM) by their ovoid appearance and the spiral tubule surrounding the virion's surface. However, this technique may introduce artifacts. We have examined Orf virus (ORFV; the prototype species of the Parapoxvirus genus) by cryoelectr
