All participants answered a standardized questionnaire to evaluate their risk factors for Q fever, including a specific section on the work practices of the shepherds. All human subjects had a blood sample taken for serology to phase I and phase II antigens of <jats:italic>C burnetii<\/jats:italic> performed by indirect immunofluorescence assay. At each participating farm, seven to nine sheep had blood samples taken for <jats:italic>C burnetii<\/jats:italic> serology to be assessed by the complement fixation test.<\/jats:p><jats:p>RESULTS: The seroprevalence to <jats:italic>C burnetii<\/jats:italic> was higher in the group of shepherds (28.4%) than the control group (1.2%) (P&lt;0.005). Among the group of shepherds, spending more than 5 h\/week in the sheep barn (P=0.06) and buying and\/or trading sheep within the past six months (P=0.004) were associated with positive <jats:italic>C burnetii<\/jats:italic> serology. A total of 137 of 334 sheep (41%) were seropositive for <jats:italic>C burnetii<\/jats:italic>. These positive sheep were distributed in 41 of the 46 flocks (89%). No correlation could be demonstrated between a serology for <jats:italic>C burnetii<\/jats:italic> in the herds and the shepherds.<\/jats:p><jats:p>CONCLUSION: Q fever is highly prevalent in the LSLRR of Quebec, affecting 89% of the flocks and 28% of the shepherds. Shepherds in this region are at increased risk for <jats:italic>C burnetii<\/jats:italic> infection in comparison to the general population.<\/jats:p>","DOI":"10.1155\/2003\/504796","type":"journal-article","created":{"date-parts":[[2016,3,15]],"date-time":"2016-03-15T07:58:23Z","timestamp":1458028703000},"page":"97-102","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["<i>Coxiella burnetii<\/i> Seroprevalence of Shepherds and Their Flocks in the Lower Saint\u2010Lawrence River Region of Quebec, Canada"],"prefix":"10.1155","volume":"14","author":[{"given":"Patrick","family":"Dolc\u00e9","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marie-Jo\u00eble","family":"B\u00e9langer","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Krzysztof","family":"Tumanowicz","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Claude P","family":"Gauthier","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Philippe","family":"Jutras","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Richard","family":"Mass\u00e9","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Claude","family":"Montpetit","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Harold","family":"Bernatchez","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dorothy","family":"McColl","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Harvey","family":"Artsob","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2003,4]]},"container-title":["Canadian Journal of Infectious Diseases and Medical Microbiology"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/downloads.hindawi.com\/journals\/cjidmm\/2003\/504796.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1155\/2003\/504796","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2024,12,31]],"date-time":"2024-12-31T05:02:27Z","timestamp":1735621347000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1155\/2003\/504796"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2003,1]]},"references-count":0,"journal-issue":{"issue":"2","published-print":{"date-parts":[[2003,1]]}},"alternative-id":["10.1155\/2003\/504796"],"URL":"https:\/\/doi.org\/10.1155\/2003\/504796","archive":["Portico"],"relation":{},"ISSN":["1712-9532","1918-1493"],"issn-type":[{"value":"1712-9532","type":"print"},{"value":"1918-1493","type":"electronic"}],"subject":[],"published":{"date-parts":[[2003,1]]},"assertion":[{"value":"2002-02-26","order":0,"name":"received","label":"Received","group":{"name":"publication_history","label":"Publication History"}},{"value":"2002-09-12","order":2,"name":"accepted","label":"Accepted","group":{"name":"publication_history","label":"Publication History"}},{"value":"2003-04-01","order":3,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}]}}
