Disease relevance of Arenaviruses, New World


High impact information on Arenaviruses, New World

  • The apparent lack of SKI-1 cleavage at the CCHF virus Gc RKPL site indicates that related proteases, other than SKI-1, are likely to be involved in the processing at this site and identical or similar sites utilized in several New World arenaviruses [3].
  • Phylogenetic analysis of NP or GPC amino acid sequences from all New World arenaviruses revealed three lineages and that Tamiami and Whitewater Arroyo viruses were probably derived from a single recombinant progenitor [4].
  • The different phylogenetic histories of the N and GPC genes indicate that the WWA virus genome is a product of recombination between two Tacaribe complex viruses [5].
  • One patient with laboratory-confirmed Machupo virus infection who received ribavirin recovered without sequelae, as did a second patient with suspected BHF whose epidemiological and clinical features were similar to those of the first patient [6].
  • The purpose of this study was to extend our knowledge on the geographic and natural rodent host ranges of New World arenaviruses in California. Sera from 1,094 sigmodontine and 112 murine rodents were tested for antibody against Whitewater Arroyo and Amapari viruses [7].

Chemical compound and disease context of Arenaviruses, New World

  • In cells infected with Machupo virus in the presence of actinomycin D the synthesis of similar sedimentation classes of RNAs and certain amounts of 28S RNA have been detected [8].
  • RNA from Machupo virus infected cells was centrifuged in a linear sucrose gradient and RNAs from gradient fractions were tested separately for template activity in a cell-free protein synthesizing system from rabbit reticulocytes [9].
