To our knowledge, no studies have been conducted to assess influenza A exposure in stray cats in regions with positive cases of wild birds. This study aimed to determine the seroprevalence of anti-influenza A antibodies in feral cats from a region in Spain with cases of positive wild birds. A cross-sectional study of stray cats (n¿=¿183) was conducted between March 2022 and March 2023. The presence of antibodies against the influenza A virus was tested using a commercial enzyme-linked immunosorbent assay kit adapted for this study and confirmed by competitive enzyme-linked immunosorbent assay for the detection of antibodies against the haemagglutinin H5. During sample collection, none of the cats exhibited clinical signs of illness. Four of the 183 animals tested showed anti-influenza A antibodies by ELISA, and the seroprevalence of influenza A was 2.19% (95% confidence interval 0.85%–5.48%). Due to the low number of positive cases detected, it appears that cats did not have an important epidemiological role in influenza A transmission during this period. info:eu-repo/semantics/openAccess All rights reserved http://www.europeana.eu/rights/rr-f/ 2.3 2024 VETERINARY SCIENCES 30 / 170 = 0.176 2024 Q1 T1 INFECTIOUS DISEASES 76 / 137 = 0.555 2024 Q3 T2 0.788 2024 Veterinary (miscellaneous) 2024 Q1 Immunology and Microbiology (miscellaneous) 2024 Q2 Public Health, Environmental and Occupational Health 2024 Q2 Epidemiology 2024 Q2 Infectious Diseases 2024 Q2 5.0 2024 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion Martínez, Mariví Rueda, Pablo Pérez, María Dolores Universidad de Zaragoza (orcid)0000-0003-2555-8425 Lacasta, Delia Universidad de Zaragoza (orcid)0000-0002-7822-6646 Marteles, Diana Universidad de Zaragoza Ruíz, Héctor Universidad de Zaragoza (orcid)0000-0002-8474-2831 Gonzalez, Ana Verde, María Teresa Universidad de Zaragoza (orcid)0000-0003-2957-1379 Pardo, Julián Universidad de Zaragoza (orcid)0000-0003-0154-0730 Arias, Maykel (orcid)0000-0002-9730-2210 Peña-Fresneda, Natacha Fernández, Antonio Universidad de Zaragoza (orcid)0000-0002-2557-4890 Trotta, Michele 1011 566 Universidad de Zaragoza Dpto.
