This study aimed to conduct a comprehensive survey of IAV in a wide range of wildlife in the Orinoco flooded savannas of Colombia, a region of high biodiversity and a strategic location for monitoring viral transmission. Sampling was conducted during both dry and rainy seasons in two localities. ELISA and qPCR targeted 2028 individuals from 173 bird, mammal, and reptile species, 124 of them without previously published reports. There were positive results for 54 species, with 34 representing first-time world reports. Of the qPCR, 13.4% were positive from birds, and 2.9% were from mammals. Seropositivity was identified in 5.7% of birds, 2.7% of mammals, and 1.3% of reptiles. These findings underscore the potential role of these diverse species as reservoirs or incidental hosts in the transmission cycle of IAV, emphasizing the need for expanded research on less-studied taxa and their ecological interactions. The results also contribute to our understanding of the epidemiology of IAV in the Neotropics and can inform future surveillance and mitigation strategies.<\/jats:p>","DOI":"10.3390\/ani15152201","type":"journal-article","created":{"date-parts":[[2025,7,28]],"date-time":"2025-07-28T07:57:24Z","timestamp":1753689444000},"page":"2201","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["A Broad Wildlife Survey of Influenza A Virus in the Orinoco Flooded Savannas from Colombia: New Reports and Perspectives"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0009-0006-9034-9143","authenticated-orcid":false,"given":"Astrid Katerine","family":"C\u00e1rdenas Parra","sequence":"first","affiliation":[{"name":"Laboratorio de Estudios Moleculares de la Orinoquia, Universidad Internacional del Tr\u00f3pico Americano (Unitr\u00f3pico), Yopal 850002, Colombia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Juan Pablo","family":"Bar\u00f3n Vera","sequence":"additional","affiliation":[{"name":"Laboratorio de Estudios Moleculares de la Orinoquia, Universidad Internacional del Tr\u00f3pico Americano (Unitr\u00f3pico), Yopal 850002, Colombia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7500-6680","authenticated-orcid":false,"given":"Iv\u00e1n Fernando","family":"Calixto-Bot\u00eda","sequence":"additional","affiliation":[{"name":"Laboratorio de Estudios Moleculares de la Orinoquia, Universidad Internacional del Tr\u00f3pico Americano (Unitr\u00f3pico), Yopal 850002, Colombia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1775-0804","authenticated-orcid":false,"given":"Nubia E.","family":"Matta","sequence":"additional","affiliation":[{"name":"Laboratorio Relaci\u00f3n Par\u00e1sito Hospedero, Departamento de Biolog\u00eda, Facultad de Ciencias, Universidad Nacional de Colombia, Bogot\u00e1 111321, Colombia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Oscar Andr\u00e9s","family":"Rodr\u00edguez-Fandi\u00f1o","sequence":"additional","affiliation":[{"name":"Laboratorio de Estudios Moleculares de la Orinoquia, Universidad Internacional del Tr\u00f3pico Americano (Unitr\u00f3pico), Yopal 850002, Colombia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6359-4000","authenticated-orcid":false,"given":"Lady Johana","family":"Correa-Higuera","sequence":"additional","affiliation":[{"name":"Laboratorio de Estudios Moleculares de la Orinoquia, Universidad Internacional del Tr\u00f3pico Americano (Unitr\u00f3pico), Yopal 850002, Colombia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,7,26]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"176","DOI":"10.18257\/raccefyn.136","article-title":"La biodiversidad de Colombia: Significado y distribuci\u00f3n regional","volume":"39","year":"2015","journal-title":"Rev.
