Influenza A(H5N1) Virus Infections in 2 Free-Ranging Black Bears (Ursus americanus), Quebec, Canada
Emerg Infect Dis. 2023 Oct;29(10):2145-2149. doi: 10.3201/eid2910.230548.ABSTRACTWholly Eurasian highly pathogenic avian influenza H5N1 clade 2.3.4.4b virus was isolated from 2 free-ranging black bears with meningoencephalitis in Quebec, Canada. We found that isolates from both animals had the D701N mutation in the polymerase basic 2 gene, previously known to promote adaptation of H5N1 viruses to mammal hosts.PMID:37735770 | DOI:10.3201/eid2910.230548 (Source: Emerging Infectious Diseases)

Viruses, Vol. 15, Pages 1909: Different Outcomes of Chicken Infection with UK-Origin H5N1-2020 and H5N8-2020 High-Pathogenicity Avian Influenza Viruses (Clade 2.3.4.4b)
Marek J. Slomka Clade 2.3.4.4 H5Nx highly pathogenic avian influenza viruses (HPAIVs) of the &ldquo;goose/Guangdong&rdquo; lineage have caused a series of European epizootics since 2014. During autumn/winter 2020&ndash;2021, several H5Nx subtypes were detected in the UK, with H5N8 being the dominant subtype in wild birds and poultry. Despite the greater subtype diversity (due to viral neuraminidase gene reassortment) reported in wild birds, only H5N8 and H5N1 subtypes caused clade 2.3.4.4 UK HPAIV poultry outbreaks during this period. The direct inoculation of layer chickens showed that H5N8-2...

Viruses, Vol. 15, Pages 1906: Spreading of the High-Pathogenicity Avian Influenza (H5N1) Virus of Clade 2.3.4.4b into Uruguay
Conclusions: The arrival of the 2.3.4.4b clade in Uruguay may have been mediated by birds that acquired the virus from Argentine and Chilean waterfowl migrating in the Pacific Flyway. (Source: Viruses)

News at a glance: Costly invasive species, cancer in younger adults, and fumigating Paris
ECOLOGY Annual cost of invasive species put at half-a-trillion dollars Invasive species cause more than $423 billion per year in damage to agriculture, fisheries, water supplies, and other ecosystem-dependent benefits worldwide, according to the summary of a comprehensive review by dozens of scientists, released this week. The monetary losses, adjusted for inflation, have quadrupled every decade since 1970 , the study’s baseline, the summary says. The report is the first on the topic from the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services, which has 143 ...

Spatio-temporal distribution & amp; seasonality of highly pathogenic avian influenza H5N1 & amp; H5N8 outbreaks in India, 2006-2021
CONCLUSIONS: Such studies on the seasonality of HPAI outbreaks would help in the development of prevention and control strategies. The recent human infections of H5N1 and H9N2 viruses highlight the need to strengthen surveillance in wild, resident, migratory birds and in poultry along with One Health studies in India.PMID:37675691 | DOI:10.4103/ijmr.ijmr_2002_22 (Source: Indian J Med Res)
