Detectan #influenza aviar A #H7N3 en #granja del norte de #México https://boletinaldia.sld.cu/aldia/2025/04/26/detectan-influenza-aviar-ah7n3-en-granja-del-norte-de-mexico/

La Secretaría de Agricultura y Desarrollo Rural de México confirmó hoy la detección del virus de influenza aviar AH7N3 en una granja comercial del municipio de Marín, en el norteño estado de Nuevo León.

An #epizootic of highly pathogenic avian #influenza virus #H7N3 in a #Mexican ecological #reserve, Arch Virol.: https://link.springer.com/article/10.1007/s00705-024-06200-6

#Phylogenetic #analysis revealed that the HPAI H7N3 virus detected in affected birds shared a close genetic relationship with Mexican H7N3 isolates from 2012.

The property is located in the #Terang region and is linked to the property at #Meredith where the #H7N3 high pathogenicity strain of avian influenza virus has resulted in numerous poultry deaths.

The following subtypes were determined and whole-genome nucleotide sequences of the isolated strains were obtained: #H1N1 (n = 2), #H3N8 (n = 8), #H4N6 (n = 2), #H7N3 (n = 2), #H8N4 (n = 1), #H10N5 (n = 1), and #H12N5 (n = 1). No high pathogenicity influenza virus H5 subtype was detected.

Phylogenetic analysis indicated that the Egyptian H6N1 strain A/Garganey/Egypt/20869C/2022(H6N1) has a unique genomic #constellation, with gene #segments inherited from different subtypes (#H5N1, #H3N8, #H7N3, H6N1, and #H10N1) that have been detected previously in AIVs from Egypt and some Eurasian countries.

-- The #zoonotic #potential of this new virus should be considered. #H7N2, #H7N3, #H7N7 viruses have all been previously associated with #conjunctivitis and/or #respiratory symptoms in #humans while in 2003 in the Netherlands a fatal case occurred following an infection with H7N7.
