This study focused on establishing a national surveillance system initiated by the Lao PDR government using a passive surveillance system of abattoir samples as a pilot model, and to gain information on contagious zoonoses, particularly Q fever and brucellosis, in the large ruminant population. A total of 683 cattle and buffalo samples were collected from six selected provinces of Lao PDR between March\u2013December 2019. Out of 271 samples tested, six samples (2.2%, 95% confidence interval (CI) of 1.0, 4.8) were positive in the Q fever antibody ELISA test. Only one sample (out of 683; 0.2%, 95% CI 0.0, 0.8) tested positive to the Brucella antibody ELISA test. Seroprevalence of these important zoonoses in Lao PDR were relatively low in cattle and buffaloes; however, extensive animal movement within the country was identified which could increase risks of spreading transboundary diseases. The study highlights the importance of ongoing animal health surveillance and the need to find cost-effective approaches for its long-term sustainability.<\/jats:p>","DOI":"10.3390\/ani11030742","type":"journal-article","created":{"date-parts":[[2021,3,8]],"date-time":"2021-03-08T23:04:39Z","timestamp":1615244679000},"page":"742","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":17,"title":["The Development of an Abattoir-Based Surveillance System in Lao PDR for the Detection of Zoonoses in Large Ruminants: Q Fever and Brucellosis Seroepidemiology as a Pilot Study"],"prefix":"10.3390","volume":"11","author":[{"given":"Jarunee","family":"Siengsanan-Lamont","sequence":"first","affiliation":[{"name":"Mahidol-Oxford Tropical Medicine Research Unit, Faculty of Tropical Medicine, Mahidol University, Bangkok 10400, Thailand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bounlom","family":"Douangngeun","sequence":"additional","affiliation":[{"name":"National Animal Health Laboratory, Department of Livestock and Fisheries, Ministry of Agriculture, Vientiane 0102, Laos"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Watthana","family":"Theppangna","sequence":"additional","affiliation":[{"name":"National Animal Health Laboratory, Department of Livestock and Fisheries, Ministry of Agriculture, Vientiane 0102, Laos"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Syseng","family":"Khounsy","sequence":"additional","affiliation":[{"name":"National Animal Health Laboratory, Department of Livestock and Fisheries, Ministry of Agriculture, Vientiane 0102, Laos"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Phouvong","family":"Phommachanh","sequence":"additional","affiliation":[{"name":"National Animal Health Laboratory, Department of Livestock and Fisheries, Ministry of Agriculture, Vientiane 0102, Laos"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Paul W.","family":"Selleck","sequence":"additional","affiliation":[{"name":"Mahidol-Oxford Tropical Medicine Research Unit, Faculty of Tropical Medicine, Mahidol University, Bangkok 10400, Thailand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nina","family":"Matsumoto","sequence":"additional","affiliation":[{"name":"Sydney School of Veterinary Science, Faculty of Science, University of Sydney, Camden 2570, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2356-7192","authenticated-orcid":false,"given":"Laurence J.","family":"Gleeson","sequence":"additional","affiliation":[{"name":"Mahidol-Oxford Tropical Medicine Research Unit, Faculty of Tropical Medicine, Mahidol University, Bangkok 10400, Thailand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6576-726X","authenticated-orcid":false,"given":"Stuart D.","family":"Blacksell","sequence":"additional","affiliation":[{"name":"Mahidol-Oxford Tropical Medicine Research Unit, Faculty of Tropical Medicine, Mahidol University, Bangkok 10400, Thailand"},{"name":"Centre for Tropical Medicine &amp; Global Health, Nuffield Department of Medicine, University of Oxford, Oxford OX1 4BH, UK"},{"name":"Lao-Oxford-Mahosot Hospital-Wellcome Trust Research Unit (LOMWRU), Mahosot Hospital, Vientiane 0100, Laos"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2021,3,8]]},"reference":[{"key":"ref_1","unstructured":"St\u00fcr, W.W., Gray, D., and Bastin, G.
