Research Question

Knowledge on patterns of host susceptibility

Research Gaps and Challenges

  • Understanding patterns of host susceptibility based on molecular markers and on host ecology
  • Molecular determinants of viral adaptation/restriction to different species/tissues
  • Determinants of host adaptation beyond the HA and NA proteins
  • Mechanisms of intra-host virus evolution

Solution Routes

  • Increasing understanding of potential reservoir species at the human/animal interface
  • Investigate what are the main species involved in maintaining the virus in wild bird metapopulation, particularly for HPAI clade 2.3.4.4b
  • To grow knowledge beyond the polybasic cleavage site on HA
  • Identify determinants of virus shedding in respiratory and / or digestive tracts
  • Do species behave differently to the virus in different geographies?
  • And production systems? Are there environmental factors? And stress
    factors?
  • Understanding transmissibility in ostriches/ducks and the resistance to
    highly pathogenic viruses resulting in potential transmission to wild birds due to farming practices

Dependencies

  • Surveillance in locations where multiple species are exposed to influenza A viruses.

State Of the Art

  • Infection in Spain in minks, nice work about change in genome and danger for humans
