Identification and characterization of a tumor necrosis factor receptor like protein encoded by Singapore grouper iridovirus.
Virus encoded tumor necrosis factor receptors (TNFRs) have been demonstrated to facilitate virus to escape from apoptosis or other host immune response for viral replication. Singapore grouper iridovirus (SGIV), a large DNA virus which belongs to genus Ranavirus, is a major pathogen resulting in hea...
Cotton leaf curl Gezira alphasatellite associated with tomato leaf curl Sudan virus approaches the expected upper size limit in the evolutio...
We report the detection of unexpectedly large cotton leaf curl Gezira alphasatellite molecules (up to 1467 nt) associated with an isolate of a novel strain of tomato leaf curl Sudan virus (ToLCSDV) in tomato plants affected by ToLCD. A recombinant nature is suggested for this ToLCSDV isolate. Copyr...
Comparative analysis of error-prone replication mononucleotide repeats across baculovirus genomes.
We mapped these MNRs in the 59 baculovirus genomes. We found that the MNR frequencies of baculovirus genomes are different and not correlated with the genome sizes. Although the average A/T content of baculoviruses is 58.67%, the A/T MNR frequency is significantly higher than that of the G/C MNRs. F...
Genetic characterization of Duck Hepatitis A Viruses isolated in China.
These results demonstrate the genetic and biological diversity of DHAVs in China and aid in understanding the epidemiology and evolution of DHAVs. Published by Elsevier B.V....
Infectious transcripts of an asymptomatic panicovirus identified from a metagenomic survey.
A new panicovirus was identified from a metagenomic survey of plant viruses in the Tallgrass Prairie Preserve (TPP), Osage County, Oklahoma, USA. Thin paspalum asymptomatic virus (TPAV) was isolated from Paspalum setaceum var. muehlenbergii. The complete 4195 nucleotide sequence encodes six proteins...
Neuraminidase amino acids 149 and 347 determine the infectivity and oseltamivir sensitivity of pandemic influenza A/H1N1 (2009) and avian in...
Pandemic influenza A/H1N1 (2009) and avian influenza A/H5N1 neuraminidase (NA) differ at two critical residues, positions 149 and 347. Recombinant influenza A viruses were constructed in which these two residues in pandemic influenza A/H1N1 (2009) NA were changed to the corresponding amino acids of...
Evidence for different patterns of natural inter-genotype recombination between two PCV2 parental strains in the field.
These results demonstrate that recombination between PCV2a and PCV2b strains can occur in cap protein coding region through different patterns and yield different recombinants. Our study not only provided new evidences that PCV2 strains can undergo recombination through a variety of patterns, but al...
VP1 protein of Foot-and-mouth disease virus (FMDV) impairs baculovirus surface display.
We constructed recombinant baculoviruses that display the protein VP1 of FMDV on their surface, with either polar (fused to gp64) or nonpolar (fused to anchor membrane from VSV-G protein) distribution. Insect cells infected with the different recombinant baculoviruses expressed VP1 fusion protein to...
Domestic cats and dogs are susceptible to H9N2 avian influenza virus.
Our results demonstrate that H9N2 AIV can infect domestic cats and dogs via the upper respiratory tract and indicate that cats are more susceptible than dogs to H9N2 AIV. These findings suggest that domestic dogs and cats may serve as host species contributing to the adaptation of H9N2 viruses in ma...
Agroinoculation of a full-length cDNA clone of cotton leafroll dwarf virus (CLRDV) results in systemic infection in cotton and the model pla...
We also demonstrated that the virus that accumulated in the agroinfected plants was transmissible by the vector A. gossypii. This result confirms the production of biologically active transmissible virions. In addition, the clone was infectious in Nicotiana benthamiana plants which developed interve...
