Abstract:
... Entry processes were compared between dengue-2 (DEN-2) virus and a DEN-2 neutralisation escape mutant virus in baby hamster kidney (BHK) cells. The mutant virus (mu6B2) was resistant to neutralisation by a monoclonal antibody, MAb 6B2. Infection of BHK cells by the wild-type DEN-2 virus resulted in direct penetration of the virions into the cytoplasm whereas the mutant virus entered cells by endoc ...

Subject:
Tick-borne encephalitis virus; artificial membranes; viruses
Abstract:
... The fusion motif of tick-borne encephalitis virus E protein has been predicted to be located within its conserved region (98–120). Results are presented to demonstrate that non-neutralizing monoclonal antibody which recognizes a synthetic peptide corresponding to residues 98–113 of the E protein sequence can block the fusion of the virus particles with artificial membranes. ...

Abstract:
... Chaperonin 10 of M. tuberculosis conferred partial or total protection against generalized foot-and-mouth disease (FMD) in guinea-pigs challenged with O₁ Lausanne FMD virus. Chaperonin 10-immunized animals mounted an antibody response to the protein, one epitope of which was found in the C-terminal half. A similar recognition pattern was observed in FMD-convalescent guinea-pigs, swine and cattle. ...

Subject:
Murine hepatitis virus; electrophoresis; membrane proteins; messenger RNA; open reading frames; ribosomes; start codon; translation (genetics); viruses
Abstract:
... The unique region of mRNA 5 of murine hepatitis virus contains two open reading frames, ORF 5a and ORF 5b. The downstream ORF 5b encodes the envelope (E) protein, an integral membrane protein of the virus. We have shown previously that the expression of ORF 5b is mediated by the internal entry of ribosomes. In the experiments reported here, we have used the in vitro translation of synthetic mRNAs ...

Six BCVs isolated in feces, intestinal content or tracheal exudate of the cows were analyzed for their antigenic properties by cross virus neutralization (VN) tests. The isolates were divided into two groups, one o ...

We determined the untranslated 5′-leader sequence for three different isolates of porcine reproductive and respiratory syndrome virus (PRRSV): pathogenic European- and American-types, as well as an American-type vaccine strain. 5′-leader from European- and American-type PRRSV differed in length (220 and 190 nt, respectively), and exhibited only approximately 50% nucleotide homology. Nevertheless, ...

Alfalfa mosaic virus; Ilarvirus; RNA; capsid; coat proteins; exoribonucleases; genome; models; virus replication; viruses
Abstract:
... Alfamo- and ilarviruses are characterized by the deficiency of their genomes (three messenger-sense RNAs) to start an infection cycle. The RNAs are in capsids built from a single species of protein of about 24 kD. A few dimers of this coat protein per RNA molecule are sufficient to activate the genome. Since the first description of genome activation [Bol JF, van Vloten-Doting L, Jaspars EMJ (1971 ...

Abstract:
... Turnip vein-clearing virus (TVCV) and tobacco mosaic virus (TMV) represent subgroups of tobamoviruses infecting cruciferous and solanaceous plants, respectively. To identify adaptations that may have been necessary in the evolution of the TVCV subgroup from a TMV-like ancestor, the infection of turnip plants by TMV and by chimeras between TMV and TVCV was explored. TMV accumulated at spatially lim ...

The phylogenetic relationships of encephalomyocarditis (EMC) viruses isolated from pigs and rodents in Europe were determined by comparison of nucleotide sequences from two different regions of the virus genome, the VP3/VP1 gene junction (part of the capsid-coding region) and part of the 3D polymerase-coding region. Thirty-five European EMC viruses could be divided into two genetic groups, one whi ...

Activation of the major immediate-early (IE) promoter (MIEP) of HCMV by dbcAMP was observed in human neuroblastoma IMR-32 cells, but not in glioma 118MGC and astrocytoma U373-MG cells. The 19 bp repeat element in the enhancer of the MIEP was most lik ...

Abstract:
... The nucleotide sequences of the 3′-terminal open reading frame (ORF3) and 3′ untranslated region (3′UTR) were determined for four Norwalk-like viruses (NLVs) belonging to genogroup 2. Three of the viruses, isolated in 1995 and 1996, were closely related to Mexico virus (92–93% nucleotide identity in ORF3). The fourth virus, isolated in 1984, was unique, showing only 49–58% nucleotide identity with ...
