This study aimed to investigate the seroprevalence and risk factors of Chlamydia and Chlamydia abortus infection in cattle in Shanxi Province. In November 2020, a large-scale investigation of Chlamydia seroprevalence was conducted on 981 cattle serum samples collected from 40 cattle farms in 11 cities of Shanxi Province. The seroprevalence of Chlamydia and C. abortus was examined by indirect hemagglutination assay (IHA) and enzyme-linked immunosorbent assay (ELISA), respectively. The seroprevalence of Chlamydia and C. abortus was 52.29% (513\/981) and 2.96% (29\/981), respectively, in cattle in Shanxi Province. Location was identified as a risk factor for Chlamydia and C. abortus infection (p &lt; 0.05). Under different management patterns, the seroprevalence of Chlamydia and C. abortus in large-scale animal farming companies was higher than that in household animal farms and animal farming cooperatives, and only the seroprevalence of Chlamydia was significantly different in different management patterns (p &lt; 0.01). The results showed that there was higher seroprevalence of Chlamydia in cattle in Shanxi Province, while C. abortus was not the dominant species. This study provided baseline information on Chlamydia infection in cattle in Shanxi Province, which constitutes valuable data for monitoring livestock health and preventing potential zoonoses.<\/jats:p>","DOI":"10.3390\/ani13020252","type":"journal-article","created":{"date-parts":[[2023,1,11]],"date-time":"2023-01-11T02:59:54Z","timestamp":1673405994000},"page":"252","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Seroprevalence and Risk Factors of Chlamydia Infection in Cattle in Shanxi Province, North China"],"prefix":"10.3390","volume":"13","author":[{"given":"Xiao-Jing","family":"Wu","sequence":"first","affiliation":[{"name":"College of Veterinary Medicine, Shanxi Agricultural University, Jinzhong 030801, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jin","family":"Gao","sequence":"additional","affiliation":[{"name":"College of Veterinary Medicine, Shanxi Agricultural University, Jinzhong 030801, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Qian","family":"Zhang","sequence":"additional","affiliation":[{"name":"College of Veterinary Medicine, Shanxi Agricultural University, Jinzhong 030801, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chen-Xu","family":"Li","sequence":"additional","affiliation":[{"name":"College of Veterinary Medicine, Shanxi Agricultural University, Jinzhong 030801, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"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":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8473-6511","authenticated-orcid":false,"given":"Qing","family":"Liu","sequence":"additional","affiliation":[{"name":"College of Veterinary Medicine, Shanxi Agricultural University, Jinzhong 030801, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"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":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yu-Ping","family":"Lei","sequence":"additional","affiliation":[{"name":"Veterinary Laboratory, Shanxi Provincial Animal Disease Prevention and Control Center, Taiyuan 030008, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Wen-Wei","family":"Gao","sequence":"additional","affiliation":[{"name":"College of Veterinary Medicine, Shanxi Agricultural University, Jinzhong 030801, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2023,1,10]]},"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.
