Highly pathogenic avian influenza (H7N1) in ostriches (Struthio camelus) [PDF]

Avian Pathology, 2000
The clinical, virological and pathological findings observed in a natural outbreak of highly pathogenic avian influenza in intensively farmed ostriches (Struthio camelus) are reported. Clinical signs characterized by anorexia, depression, nervous and enteric signs were observed in young birds, which resulted in death of 30% of the affected birds. Virus

The Role of miRNAs in Chicken Immune Regulation and Prospects for Disease‐Resistant Breeding

Animal Research and One Health, EarlyView.
A schematic workflow illustrating the screening of disease‐resistant miRNAs and the generation of miRNA‐based disease‐resistant chickens via PGC‐mediated germline genome editing. ABSTRACT MicroRNAs (miRNAs) are emerging as pivotal regulators of the immune system, playing a decisive role in shaping disease resistance in chicken.

Characterization of highly pathogenic avian influenza virus in retail dairy products in the US

medRxiv
In March 2024, clade 2.3.4.4b H5N1 highly pathogenic avian influenza virus (HPAIV) was detected in dairy cattle in the US, and it was discovered that the virus could be detected in raw milk. Although affected cow’s milk is diverted from human consumption

Highly pathogenic avian influenza and wild birdsr

Uirusu, 2009
Highly pathogenic avian influenza virus (HPAIV) subtype H5N1 prevails worldwide and causes serious problems in poultry industry. The virus is also known as one of the most important zoonotic agents derived from avian species. Because many bird species other than poultry such as chicken and duck are susceptible for HPAIV infection, wild birds are ...

Free-grazing Ducks and Highly Pathogenic Avian Influenza, Thailand

Emerging Infectious Diseases, 2006
Thailand has recently had 3 epidemic waves of highly pathogenic avian influenza (HPAI); virus was again detected in July 2005. Risk factors need to be identified to better understand disease ecology and assist HPAI surveillance and detection. This study analyzed the spatial distribution of HPAI outbreaks in relation to poultry, land use, and other ...

Highly Pathogenic Avian Influenza A(H5N8) Virus, Cameroon, 2017 [PDF]

Emerging Infectious Diseases, 2018
Highly pathogenic avian influenza A(H5N8) viruses of clade 2.3.4.4 spread into West Africa in late 2016 during the autumn bird migration. Genetic characterization of the complete genome of these viruses detected in wild and domestic birds in Cameroon in January 2017 demonstrated the occurrence of multiple virus introductions.

Heat Stress and Gut Microbiome Dynamics in Poultry: Interplay, Consequences, and Mitigation Strategies

Animal Research and One Health, EarlyView.
Heat stress disrupts gut microbial balance in poultry, impairing nutrient absorption and immunity. This review outlines the interplay between thermal stress and microbiome dynamics and discusses integrative mitigation strategies, probiotics, phytogenics, cooling systems, and genetic adaptation to enhance poultry resilience.

The evolutionary landscape and serotypic dynamics of avian infectious bronchitis virus from spike protein

iMetaOmics, EarlyView.
This study integrates two decades of surveillance with genomic and structural analyses to decipher how spike protein glycosylation haplotypes drive avian coronavirus evolution. We uncover how specific glycosylation patterns associate with receptor‐binding affinity, shape global transmission dynamics, and correlate with clinical outcomes.
