In Papua New Guinea (PNG), the epidemiology of JEV remains poorly understood, with limited data on its circulation in pig populations. This study aimed to determine the seroprevalence of JEV in commercial and semicommercial pig farms in Central Province, PNG, a region experiencing rapid urban and agricultural expansion.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods:<\/jats:title>\n                    <jats:p>Serum samples (n = 136) were collected from grower (5\u20137 months old) and breeder pigs (8\u201336 months old) on three farms and tested using competitive ELISA for JEV antibodies, with follow-up testing to resolve cross-reactivity with antigenically related orthoflaviviruses.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>Overall, 45% of pigs tested positive for JEV-specific antibodies. By age, a significantly greater proportion of grower pigs were seronegative to JEV, and although seropositivity was similar in grower and breeder pigs, breeder pigs showed higher proportions of cross-reactive results, suggesting multiple exposure to JEV or other orthoflaviviruses. No significant association was found between JEV serostatus and reproductive outcomes in breeding sows.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>These findings provide evidence of JEV circulation in a densely populated region of PNG and support the need for integrated One Health surveillance to inform risk-based control strategies.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/15303667261442507","type":"journal-article","created":{"date-parts":[[2026,4,13]],"date-time":"2026-04-13T14:54:29Z","timestamp":1776092069000},"page":"496-502","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":1,"title":["Seroprevalence of Japanese Encephalitis in Pigs in Central Province, Papua New Guinea"],"prefix":"10.1177","volume":"26","author":[{"given":"Elaine","family":"Hevoho","sequence":"first","affiliation":[{"name":"Animal Health Section, Technical &amp; Advisory Division, National Agriculture Quarantine &amp; Inspection Authority, Port Moresby, Papua New Guinea."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Antonio","family":"Di Rubbo","sequence":"additional","affiliation":[{"name":"Australian Centre for Disease Preparedness, CSIRO, Geelong, Australia."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andy K.","family":"Yombo","sequence":"additional","affiliation":[{"name":"Animal Health Section, Technical &amp; Advisory Division, National Agriculture Quarantine &amp; Inspection Authority, Port Moresby, Papua New Guinea."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"David T.","family":"Williams","sequence":"additional","affiliation":[{"name":"Australian Centre for Disease Preparedness, CSIRO, Geelong, Australia."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bruce","family":"Gummow","sequence":"additional","affiliation":[{"name":"Discipline of Veterinary Science, James Cook University, Townsville, Australia."},{"name":"Department of Production Animal Studies, Faculty of Veterinary Science, University of Pretoria, Pretoria, South Africa."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0963-4926","authenticated-orcid":false,"given":"Victoria J.","family":"Brookes","sequence":"additional","affiliation":[{"name":"Sydney School of Veterinary Science, Faculty of Science, The University of Sydney, Camperdown, Australia."},{"name":"Sydney Infectious Diseases Institute, Faculty of Medicine and Health, The University of Sydney, Camperdown, Australia."}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2026,4,13]]},"reference":[{"key":"e_1_3_3_2_1","first-page":"e00895","article-title":"Surveillance of Japanese encephalitis virus in piggery effluent and environmental samples: A complementary tool for outbreak detection","author":"Ahmed W","year":"2025","unstructured":"Ahmed W, , Gebrewold M, , Williams DT, et al.
