Characterization

Characterization

Research Question

  • Characterization of influenza virus (biological, sequences, viruses, phenotype)

Research Gaps and Challenges

  • Characterize determinants of high- vs. low-pathogenicity avian influenza also outside the HA cleavage site Inability/ lack of ease in detecting true reassortment vs. Contamination of sample
  • Characterize zoonotic propensity
  • Limitations for in vivo testing due to animal welfare laws
  • Characterize antigenic properties with respect to vaccine susceptibility
  • Failure to maintain sample authenticity thus inability to study observed outcomes of infection
  • Transparency about human impacts
  • Lack of understanding how genomic reassortment is made exactly

Solution Routes

  • Loss of function experiments both in vitro and in vivo
  • Study virus transmission across interfaces
  • Identification of antibody epitopes important for antigenic drift in swine and poultry species
  • Development of models to predict epitopes based on HA sequence evolution
  • Promotion and adoption of a standard classification scheme (e.g., the global swine clade classification scheme and the H5 clade classification scheme) – and have this classification updated in real time (I.e.: standardized next strain, etc.)

Dependencies

  • Virus isolates
  • Pathogenicity models
  • Interface transmission models
  • Genomic surveillance in multiple hosts and even different sites within host
