To assess the risk of psittacosis posed by pet birds, the seroprevalence of <jats:italic>Chlamydia psittaci<\/jats:italic> antibodies in 360 Eurasian siskins (<jats:italic>Carduelis spinus<\/jats:italic>), 289 oriental skylarks (<jats:italic>Alauda arvensis<\/jats:italic>) and 36 black-tailed grosbeaks (<jats:italic>Coccothraustes migratorius<\/jats:italic>) in Gansu province, north-western China was detected by an indirect haemagglutination assay. Twenty-seven out of 289 (9.34\u200a%) <jats:italic>Alauda arvensis<\/jats:italic>, 45 out of 360 (12.50\u200a%) <jats:italic>Carduelis spinus<\/jats:italic> and 2 out of 36 (5.56\u200a%) <jats:italic>Coccothraustes migratorius<\/jats:italic> were positive for <jats:italic>Chlamydia psittaci<\/jats:italic> infection at a cut-off dilution of 1\u200a:\u200a16. The prevalence of <jats:italic>Chlamydia psittaci<\/jats:italic> was higher in <jats:italic>Carduelis spinus<\/jats:italic> (12.5\u200a%) than in <jats:italic>Alauda arvensis<\/jats:italic> (9.34\u200a%) and <jats:italic>Coccothraustes migratorius<\/jats:italic> (5.56\u200a%); however, the differences were not statistically significant (<jats:italic>P<\/jats:italic>&gt;0.05). Statistical analysis indicated that <jats:italic>Chlamydia psittaci<\/jats:italic> seroprevalence in adult pet birds (12.4\u200a%, 67\/540) was significantly higher than that in juvenile pet birds (4.83\u200a%, 7\/145) (<jats:italic>P<\/jats:italic>&lt;0.01). There was no statistical difference in <jats:italic>Chlamydia psittaci<\/jats:italic> seroprevalence between male (12.4\u200a%) and female (8.27\u200a%) birds. To our knowledge, this is the first report indicating the seroprevalence of <jats:italic>Chlamydia psittaci<\/jats:italic> exposure in pet birds in China. Our results indicate that close contact with pet birds poses the risk of zoonotic transmission of <jats:italic>Chlamydia psittaci<\/jats:italic>.<\/jats:p>","DOI":"10.1099\/jmm.0.070003-0","type":"journal-article","created":{"date-parts":[[2014,1,21]],"date-time":"2014-01-21T03:06:20Z","timestamp":1390273580000},"page":"578-581","source":"Crossref","is-referenced-by-count":31,"title":["Chlamydia psittaci exposure in pet birds"],"prefix":"10.1099","volume":"63","author":[{"given":"W.","family":"Cong","sequence":"first","affiliation":[{"name":"College of Animal Science and Technology, Jilin Agricultural University, Changchun, Jilin Province 130118, PR China"},{"name":"State Key Laboratory of Veterinary Etiological Biology, Lanzhou Veterinary Research Institute, Chinese Academy of Agricultural Sciences, Lanzhou, Gansu Province 730046, PR China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"S.
