1. Full-length infectious clone of a low passage dengue virus serotype 2 from Brazil
Full-length dengue virus (DENV) cDNA clones are an invaluable tool for many studies, including those on the development of attenuated or chimeric vaccines and on host-virus interactions. Furthermore, the importance of low passage DENV infectious clones should be highlighted, as these may harbour critical and unique strain-specific viral components from field

2. A two-plasmid strategy for engineering a dengue virus type 3 infectious clone from primary Brazilian isolate
As infecções causadas por dengue representam uma das mais prevalentes doenças transmitidas por artrópodes mundialmente, causando um amplo espectro de manifestações clínicas. A tecnologia de clones infecciosos é uma importante ferramenta para o entendimento da biologia do vírus da dengue (DENV). Clones de cDNA infeccioso têm sido construídos para m

3. MAPEAMENTO E DELEÇÃO DE EPÍTOPOS LINEARES DE LINFÓCITOS B EM PROTEÍNAS DO VÍRUS DA SÍNDROME RESPIRATÓRIA E REPRODUTIVA DOS SUÍNOS PARA A PRODUÇÃO DE UMA VACINA DIFERENCIAL / MAPPING AND DELETION OF B-CELL LINEAR EPITOPES IN PROTEINS OF PORCINE REPRODUCTIVE AND RESPIRATORY SYNDROME VIRUS FOR THE PRODUCTION OF A DIFFERENTIAL VACCINE
Porcine reproductive and respiratory syndrome virus (PRRSV) was isolated for the first time in 1991 and since then it has been associated with significant economic losses to the pig industry worldwide. Although vaccination against PRRSV is widely used, an important advance would be the development of marker vaccines allowing serologic discrimination between

4. The early use of yellow fever virus strain 17D for vaccine production in Brazil - a review
The use of yellow fever (YF) virus 17D strain for vaccine production adapted in Brazil since its introduction in 1937 was reviewed. This was possible due to the availability of official records of vaccine production. The retrieved data highlight the simultaneous use of several serially passaged 17D substrain viruses for both inocula and vaccine preparation t

5. Infectious cDNA Clone of the Epidemic West Nile Virus from New York City
We report the first full-length infectious clone of the current epidemic, lineage I, strain of West Nile virus (WNV). The full-length cDNA was constructed from reverse transcription-PCR products of viral RNA from an isolate collected during the year 2000 outbreak in New York City. It was cloned into plasmid pBR322 under the control of a T7 promoter and stabl

6. Infectious Transcripts from Cloned Genome-Length cDNA of Porcine Reproductive and Respiratory Syndrome Virus
The 5′-terminal end of the genomic RNA of the Lelystad virus isolate (LV) of porcine reproductive and respiratory syndrome virus was determined. To construct full-length cDNA clones, the 5′-terminal sequence was ligated to cDNA clones covering the complete genome of LV. When RNA that was transcribed in vitro from these full-length cDNA clones was transfe

7. Infectious cDNA clones of the DA strain of Theiler's murine encephalomyelitis virus.
The DA strain and other members of the TO subgroup of Theiler's murine encephalomyelitis viruses cause a persistent demyelinating infection, whereas the GDVII strain and other GDVII subgroup strains cause an acute lethal polioencephalomyelitis. We generated an infectious DA cDNA clone inserted into a transcription vector. Virus derived from transfection of t

8. Construction of a genome-length cDNA clone for human astrovirus serotype 1 and synthesis of infectious RNA transcripts.
We have constructed a genome-length cDNA clone for human astrovirus serotype 1. When a human colon cancer-derived cell line, CaCo-2, is transfected with RNA transcribed in vitro from this cDNA clone, infectious virus is produced at titers close to those observed after infection with intact astrovirus. A rodent cell line, BHK, which is largely refractory to a

9. Nucleotide sequence of a cDNA clone carrying the glycoprotein gene of infectious hematopoietic necrosis virus, a fish rhabdovirus.
The nucleotide sequence of the mRNA encoding the glycoprotein of infectious hematopoietic necrosis virus was determined from a cDNA clone containing the entire coding region. The G-protein cDNA is 1,609 nucleotides long (excluding the polyadenylic acid) and encodes a protein of 508 amino acids. The predicted amino acid sequence was compared with that of the

10. Construction of an Infectious cDNA Clone of Aichi Virus (a New Member of the Family Picornaviridae) and Mutational Analysis of a Stem-Loop Structure at the 5′ End of the Genome
Aichi virus is the type species of a new genus, Kobuvirus, of the family Picornaviridae. In this study, we constructed a full-length cDNA clone of Aichi virus whose in vitro transcripts were infectious to Vero cells. During construction of the infectious cDNA clone, a novel sequence of 32 nucleotides was identified at the 5′ end of the genome. Computer-ass

11. Generation of an Infectious Clone of VR-2332, a Highly Virulent North American-Type Isolate of Porcine Reproductive and Respiratory Syndrome Virus
A full-length cDNA clone of the prototypical North American porcine reproductive and respiratory syndrome virus (PRRSV) isolate VR-2332 was assembled in the plasmid vector pOK12. To rescue infectious virus, capped RNA was transcribed in vitro from the pOK12 clone and transfected into BHK-21C cells. The supernatant from transfected monolayers were serially pa

12. Recovery of Virulent and RNase-Negative Attenuated Type 2 Bovine Viral Diarrhea Viruses from Infectious cDNA Clones
Cloned cDNA derived from the genome of the virulent type 2 bovine viral diarrhea virus (BVDV) strain NY'93/C was sequenced and served for establishment of the infectious cDNA clone pKANE40A. Virus recovered from pKANE40A exhibited growth characteristics similar to those of wild-type BVDV NY'93/C and proved to be clinically indistinguishable from the wild-typ
