Figure

Phylogenetic analysis of highly pathogenic avian influenza A(H5N1) clade 2.3.4.4b virus detected in domestic cat, France, 2022. Tree was created by using MEGA 7 software (https://megasoftware.net) and the neighbor-joining method with 1,000 bootstrap replicates for complete concatenated HPAI H5N1 virus segments. All sequences belong to the A/duck/Saratov/29-02V/2021–like genotype. Red solid circle indicates virus sequence from cat; black solid circle indicates sequence from a nearby duck farm. Both sequences are available in the GISAID database (https://www.gisaid.org) under accession nos. EPI_ISL_16395206 (cat) and EPI_ISL_16740903 (duck). Red bracket indicates closely related sequences detected during the same period and area in France from domestic bird farms. Scale bar indicates nucleotide substitutions per site.
