However, a management strategy is lacking to protect at\u2010risk humans handling infected aborted material and pregnant mares. This study proposes a protocol for approaching <jats:italic>C. psittaci<\/jats:italic> foetal loss after investigating four foetal losses that occurred on a horse stud in the Hunter Valley, Australia in 2021. Swabs from the foetal loss cases (<jats:italic>n<\/jats:italic>\u00a0=\u00a04), close contact mares (<jats:italic>n<\/jats:italic>\u00a0=\u00a059), and foals of the close contact mares (<jats:italic>n<\/jats:italic>\u00a0=\u00a033) were collected and tested for <jats:italic>C. psittaci<\/jats:italic> using both isothermal points of care and quantitative polymerase chain reaction (qPCR) laboratory\u2010based testing. Genotyping was performed utilising <jats:italic>C. psittaci<\/jats:italic> multilocus sequence typing and <jats:italic>omp<\/jats:italic>A sequencing from <jats:italic>C. psittaci<\/jats:italic> positive pooled foetal and placental (<jats:italic>n<\/jats:italic>\u00a0=\u00a03) DNA. Foetal and placental samples from the four foetal loss cases were all positive for <jats:italic>C. psittaci<\/jats:italic> with 100% agreement between the isothermal swab testing on the farm and qPCR DNA testing at an external laboratory. Genotyping revealed the clonal and identical sequence type 24 (ST24) <jats:italic>C. psittaci<\/jats:italic> strains in all samples. <jats:italic>C. psittaci<\/jats:italic> was not detected in close contact with mares or their foals. There was no statistically significant difference in foal survival between the close contact mare groups that did and did not receive antimicrobial intervention (P\u2009&gt;\u20090.05). The proposed protocol is intended to raise awareness and begin a discussion for guidelines around handling of chlamydial foetal loss cases in late pregnant mares which pose a zoonotic threat to farm workers and veterinarians.<\/jats:p>","DOI":"10.1111\/avj.13206","type":"journal-article","created":{"date-parts":[[2022,9,8]],"date-time":"2022-09-08T03:54:53Z","timestamp":1662609293000},"page":"600-604","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Suspected chlamydial foetal loss highlights the need for standardised on\u2010farm protocols"],"prefix":"10.1111","volume":"100","author":[{"given":"SI","family":"Anstey","sequence":"first","affiliation":[{"name":"Centre for Bioinnovation University of the Sunshine Coast  Sippy Downs Queensland Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"C","family":"Jenkins","sequence":"additional","affiliation":[{"name":"NSW Department of Primary Industries, Animal and Plant Health laboratories Elizabeth Macarthur Agricultural Institute  Menangle New South Wales Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1340-2562","authenticated-orcid":false,"given":"M","family":"Jelocnik","sequence":"additional","affiliation":[{"name":"Centre for Bioinnovation University of the Sunshine Coast  Sippy Downs Queensland Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2022,9,7]]},"reference":[{"key":"e_1_2_5_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.tvjl.2021.105683"},{"key":"e_1_2_5_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.onehlt.2017.02.003"},{"key":"e_1_2_5_4_1","doi-asserted-by":"publisher","DOI":"10.1038\/s41426-018-0089-y"},{"key":"e_1_2_5_5_1","doi-asserted-by":"publisher","DOI":"10.1099\/jmm.0.001284"},{"key":"e_1_2_5_6_1","doi-asserted-by":"publisher","DOI":"10.1186\/s12917-021-02986-8"},{"key":"e_1_2_5_7_1","doi-asserted-by":"publisher","DOI":"10.3390\/pathogens10081015"},{"key":"e_1_2_5_8_1","doi-asserted-by":"publisher","DOI":"10.1038\/emi.2016.135"},{"key":"e_1_2_5_9_1","unstructured":"Australian Institute of Health and Welfare.National Notifiable Diseases Surveillance System.
