Avian chlamydiosis (AC), caused by <jats:italic>Chlamydia psittaci<\/jats:italic> (<jats:italic>C. psittaci<\/jats:italic>) as well as new emerging <jats:italic>C. avium<\/jats:italic>, <jats:italic>C. gallinacea<\/jats:italic> and <jats:italic>C. ibidis<\/jats:italic>, have been described in nearly 500 avian species worldwidely. The Crested Ibis (<jats:italic>Nipponia nippon<\/jats:italic>) is a world endangered avian species with limited population and vulnerable for various infections. To get a better understanding of the prevalence of <jats:italic>Chlamydia<\/jats:italic> spp. in the endangered Crested Ibis, faecal samples were collected and analysed. The results confirmed that 20.20% (20\/99) of the faecal samples were positive for <jats:italic>Chlamydiaceae<\/jats:italic> and were identified as <jats:italic>C. ibidis<\/jats:italic> with co-existence of <jats:italic>C. psittaci<\/jats:italic> in one of the 20 positive samples. In addition, <jats:italic>ompA<\/jats:italic> sequence of <jats:italic>C. psittaci<\/jats:italic> obtained in this study was classified into the provisional genotype Matt116, while that of <jats:italic>C. ibidis<\/jats:italic> showed high genetic diversity, sharing only 77% identity with <jats:italic>C. ibidis<\/jats:italic> reference strain 10-1398\/6. We report for the first time the presence of <jats:italic>C. ibidis and C. psittaci<\/jats:italic> in the Crested Ibis, which may indicate a potential threat to the endangered birds and should be aware of the future protection practice.<\/jats:p>","DOI":"10.1017\/s0950268819002231","type":"journal-article","created":{"date-parts":[[2020,1,8]],"date-time":"2020-01-08T00:14:31Z","timestamp":1578442471000},"source":"Crossref","is-referenced-by-count":36,"title":["Detection
