We studied the reliability of measuring the level of antibodies against<jats:italic>Coxiella burnetii<\/jats:italic>in bulk-tank milk (BTM) to estimate the seroprevalence of<jats:italic>C. burnetii<\/jats:italic>in dairy sheep in 34 flocks. We then estimated the seroprevalence of<jats:italic>C. burnetii<\/jats:italic>in 154 dairy sheep flocks according to the level of antibodies in BTM. We tested for the accuracy of our estimation at the population level by comparing predicted mean<jats:italic>C. burnetii<\/jats:italic>flock seroprevalence with that obtained in another survey performed on the same population. Our findings showed that testing BTM by ELISA is a cost-effective and relatively good index of the seroprevalence of<jats:italic>C. burnetii<\/jats:italic>in dairy sheep and may be a useful tool for epidemiological surveillance at the population level.<\/jats:p>","DOI":"10.1017\/s0950268810003134","type":"journal-article","created":{"date-parts":[[2011,1,20]],"date-time":"2011-01-20T15:53:46Z","timestamp":1295538826000},"page":"1631-1636","source":"Crossref","is-referenced-by-count":17,"title":["Measuring antibody levels in bulk-tank milk as an epidemiological tool to search for the status of<i>Coxiella burnetii<\/i>in dairy sheep"],"prefix":"10.1017","volume":"139","author":[{"given":"F.","family":"RUIZ-FONS","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"I.","family":"ASTOBIZA","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"J.
