However, the information on Chlamydia infection in sheep was limited in Shanxi Province, northern China. In the present study, a total of 984 serum samples of sheep were collected from 11 regions in Shanxi Province, northern China in the autumn of 2020. The antibodies against Chlamydia and Chlamydia abortus were examined by the indirect hemagglutination assay (IHA) and indirect enzyme-linked immunosorbent assay (ELISA), respectively. The result showed that 351 (35.67%, 95% CI 32.68\u201338.66) of 984 serum samples were positive for Chlamydia, and the seroprevalence ranged from 6.67% to 70.79% among the different regions. In addition, antibodies to C. abortus infection were detected in 78 (7.93%, 95% CI 6.24\u20139.61) of 984 serum samples, and the seroprevalence ranged from 6.24% to 14.81% among the different regions. This is the first report on the seroprevalence of Chlamydia and C. abortus in sheep in Shanxi province, northern China. The findings provide baseline information for preventing and controlling Chlamydia infection in sheep in Shanxi Province, China.<\/jats:p>","DOI":"10.3390\/vetsci9120656","type":"journal-article","created":{"date-parts":[[2022,11,24]],"date-time":"2022-11-24T02:54:05Z","timestamp":1669258445000},"page":"656","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["The Seroprevalence of Chlamydia Infection in Sheep in Shanxi Province, China"],"prefix":"10.3390","volume":"9","author":[{"given":"Chen-Xu","family":"Li","sequence":"first","affiliation":[{"name":"College of Veterinary Medicine, Shanxi Agricultural University, Jinzhong 030801, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jin","family":"Gao","sequence":"additional","affiliation":[{"name":"College of Veterinary Medicine, Shanxi Agricultural University, Jinzhong 030801, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sheng-Rong","family":"Shi","sequence":"additional","affiliation":[{"name":"College of Veterinary Medicine, Shanxi Agricultural University, Jinzhong 030801, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wen-Wei","family":"Gao","sequence":"additional","affiliation":[{"name":"College of Veterinary Medicine, Shanxi Agricultural University, Jinzhong 030801, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2530-4628","authenticated-orcid":false,"given":"Xing-Quan","family":"Zhu","sequence":"additional","affiliation":[{"name":"College of Veterinary Medicine, Shanxi Agricultural University, Jinzhong 030801, China"},{"name":"Key Laboratory of Veterinary Public Health of Higher Education of Yunnan Province, College of Veterinary Medicine, Yunnan Agricultural University, Kunming 650201, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yu-Ping","family":"Lei","sequence":"additional","affiliation":[{"name":"Veterinary Laboratory, Shanxi Provincial Animal Disease Prevention and Control Center, Taiyuan 030008, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yu","family":"Zhang","sequence":"additional","affiliation":[{"name":"Veterinary Laboratory, Shanxi Provincial Animal Disease Prevention and Control Center, Taiyuan 030008, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7621-4628","authenticated-orcid":false,"given":"Wen-Bin","family":"Zheng","sequence":"additional","affiliation":[{"name":"College of Veterinary Medicine, Shanxi Agricultural University, Jinzhong 030801, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,11,24]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"385","DOI":"10.1038\/nrmicro.2016.30","article-title":"Chlamydia cell biology and pathogenesis","volume":"14","author":"Elwell","year":"2016","journal-title":"Nat.
