Since the 1950s, pond sliders have been imported worldwide as companion animals, but have often ended up in foreign ecosystems with great ecological consequences. Moreover, both autochthonous and invasive species of turtles can be carriers of pathogens, including Chlamydiaceae. In the present study, pulmonary tissues collected from four Trachemys scripta were tested with a 23S-targeting real-time PCR (rPCR) specific for the Chlamydiaceae family. The turtles were hosted in a rescue center for wild exotic animals located in northeastern Italy, and were found dead after the hibernation period. Two out of four individuals resulted positive in rPCR for the presence of Chlamydiaceae. Further characterization of this positivity was performed by phylogenetic analysis of the 16S rRNA and outer membrane protein A genes. The phylogenetic tree showed that these chlamydial strains are identical to a novel Chlamydia reported in 2017 in Polish freshwater turtles, and closely related to Chlamydia pneumoniae and to other chlamydial strains found in reptiles. This first finding evidences the presence of this Chlamydia strain in Italian turtles, but further studies will be necessary to confirm the presence and the strain pathogenicity and to evaluate its prevalence in the local turtles\u2019 population.<\/jats:p>","DOI":"10.3390\/ani12060784","type":"journal-article","created":{"date-parts":[[2022,3,20]],"date-time":"2022-03-20T21:25:00Z","timestamp":1647811500000},"page":"784","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Detection of a Novel Chlamydia Species in Invasive Turtles"],"prefix":"10.3390","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7809-0331","authenticated-orcid":false,"given":"Laura","family":"Bellinati","sequence":"first","affiliation":[{"name":"Istituto Zooprofilattico Sperimentale delle Venezie, 35020 Legnaro, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Stefano","family":"Pesaro","sequence":"additional","affiliation":[{"name":"Dipartimento di Scienze Agro-Alimentari, Ambientali e Animali Sezione di Patologia Veterinaria, Universit\u00e0 degli Studi di Udine, Via Sondrio, 33100 Udine, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8837-866X","authenticated-orcid":false,"given":"Federica","family":"Marcer","sequence":"additional","affiliation":[{"name":"Dipartimento di Medicina Animale, Produzioni e Salute, Universit\u00e0 degli Studi di Padova, 35020 Legnaro, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6738-2125","authenticated-orcid":false,"given":"Patrizia","family":"Danesi","sequence":"additional","affiliation":[{"name":"Istituto Zooprofilattico Sperimentale delle Venezie, 35020 Legnaro, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2104-4531","authenticated-orcid":false,"given":"Alda","family":"Natale","sequence":"additional","affiliation":[{"name":"Istituto Zooprofilattico Sperimentale delle Venezie, 35020 Legnaro, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6056-7821","authenticated-orcid":false,"given":"Letizia","family":"Ceglie","sequence":"additional","affiliation":[{"name":"Istituto Zooprofilattico Sperimentale delle Venezie, 35020 Legnaro, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,3,20]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"37","DOI":"10.1017\/S0030605300020275","article-title":"Red-eared terrapin farms and conservation","volume":"20","author":"Warwick","year":"1986","journal-title":"Oryx"},{"key":"ref_2","first-page":"155","article-title":"Alien freshwater turtles which may become established in Japan in the near future","volume":"2","author":"Yasukawa","year":"2005","journal-title":"Bull.
