Abstract

Three strains of H6N6 subtype avian influenza virus (AIV) were isolated from live-poultry markets of central China during 2009-2010. A phylogenetic analysis showed that these isolates originated from gene reassortment among different virus lineages of the H6 subtype. In an experimental infection of animals, the selected isolate was non-pathogenic for chickens and low-pathogenic for mice. The wild-type isolate was capable of replication in mouse lung without prior adaptation, and the virulence to mice increased rapidly during adaption in mouse lung. The genomes of viruses of passage 0 (P0), P4, and P8 were sequenced and compared, and virulence-related amino acid substitutions were found in multiple sites during mouse lung passage.

Keynote webinar | Spotlight on medication adherence

Live: Thursday 27th June 2024, 18:00-19:30 (CEST)

WHO estimates that half of all patients worldwide are non-adherent to their prescribed medication. The consequences of poor adherence can be catastrophic, on both the individual and population level.

Join our expert panel to discover why you need to understand the drivers of non-adherence in your patients, and how you can optimize medication adherence in your clinics to drastically improve patient outcomes.
