Protection conferred by an H5 DNA vaccine against highly pathogenic avian influenza in chickens: The effect of vaccination schedules.
highly pathogenic avian influenza (HPAI) viruses of the Asian lineage (A/goose/Guangdong/1/96) belonging to clade 2.3.4.4 have spread worldwide through wild bird migration in two major waves: in 2014/2015 ...
Combined Phylogeographic Analyses and Epidemiologic Contact Tracing to Characterize Atypically Pathogenic Avian Influenza (H3N1) Epidemic, Belgium, 2019.
call for detailed investigations of dispersal dynamics of epidemics. We integrated phylogeographic and epidemiologic analyses to investigate the dynamics of a low pathogenicity avian influenza (H3N1) ...
Concomitant NA and NS deletion on avian Influenza H3N1 virus associated with hen mortality in France in 2019.
virus showed that all segment sequences belonged to the Eurasian lineage and were phylogenetically very close to many of the Belgian H3N1 viruses detected in 2019. The French virus presented two genetic ...
Has Epizootic Become Enzootic? Evidence for a Fundamental Change in the Infection Dynamics of Highly Pathogenic Avian Influenza in Europe, 2021.
reservoirs. We propose contrasting hypotheses for this emergence: (i) resident viruses have been maintained, presumably in wild birds, in northern Europe throughout the summer of 2021 to cause some of the ...
Redesign and Validation of a Real-Time RT-PCR to Improve Surveillance for Avian Influenza Viruses of the H9 Subtype.
Chain Reaction Abstract: Avian influenza viruses of the H9 subtype cause significant losses to poultry production in endemic regions of Asia, Africa and the Middle East and pose a risk to human health. ...
Study of the underlying mechanisms and consequences of pathogenicity differences between two in vitro selected G1-H9N2 clones originating from a single isolate.
significant economic losses in the commercial poultry industry due to reduced egg production and increased mortality. The field observations have shown that H9N2 viruses circulate and naturally mix with other ...
Complete Coding Sequences of One H9 and Three H7 Low-Pathogenic Influenza Viruses Circulating in Wild Birds in Belgium, 2009 to 2012
Publication Type: Peer reviewed scientific article Authors: Steven Van Borm; Rosseel, Toon; Sylvie Marché; Mieke Steensels; Vangeluwe, Didier; Linden, Annick; Thierry van den Berg; Bénédicte Lambrecht Source: Genome Announcements, Volume 4, Issue 3 (2016) ...
Biosafety risk assessment and management of laboratory-derived influenza A (H5N1) viruses transmissible in ferrets
for human-to-human transmission and retain their current virulence. Recently, two research teams have succeeded in modifying HPAI A (H5N1) viruses in such a way that they could be efficiently ...
Genesis and spread of multiple reassortants during the 2016/2017 H5 avian influenza epidemic in Eurasia.
and occasionally in humans. In recent years, H5 HPAI viruses of this lineage infecting poultry in Asia have spilled over into wild birds and spread via bird migration to countries in Europe, Africa, and ...
