  • In other words, competition exists between viruses and their hosts to utilize the limited amount of cellular translation machinery. (mdpi.com)
  • 17 ) used fluorescently labeled viruses to demonstrate that viruses could control the abundance of susceptible hosts. (asm.org)
  • There is a theory that some viruses are not just harmless to their hosts, but may even be beneficial to them because they cause deadly disease in their enemies - such as man. (lrb.co.uk)
  • A virus with reduced pathogenicity as a result of treatment or repeated passage through hosts. (tabers.com)
  • Viral transmission is the process by which viruses spread between hosts. (conferenceseries.com)
  • Recombinant yellow fever viruses are affective therapeutic vaccines for treatment of murine experimental solid tumors and pulmonary metastases", Journal of Viroloqy (2000), 74(19):9197-9205. (lens.org)
  • 400-fold increase in newly replicated plasmid in cells infected with vaccinia virus. (biomedcentral.com)
  • To further investigate the possible homology of F12 and DNAPs, we used the sequence of the F12 homolog encoded by the most distant from VACV, early branching chordopoxvirus, the Nile Crocodile Virus (NCV) (YP_784228), as the query for a new PSI-BLAST search. (biomedcentral.com)
  • The vast sequence divergence among different virus groups has presented a great challenge to alignment-based analysis of virus phylogeny. (biomedcentral.com)
  • Furthermore, preliminary sequence analysis of persistent virus revealed a single nucleotide substitution within the VP1 coding region, resulting in the V50A amino acid substitution. (deepdyve.com)
