It is the causal agent of avian chlamydiosis and psittacosis in humans and it is globally distributed. Chlamydia psittaci is one of the main zoonotic pathogens transmitted by birds. In Argentina, there has been limited research on the prevalence and genetic variability of C. psittaci. The aim of this study was to detect and genotype C. psittaci using molecular techniques in birds living in Buenos Aires City, Argentina, during the period 2012\u20132015. A descriptive, observational, retrospective and cross-sectional study was carried out. A total of 983 bird samples submitted for diagnosis of avian chlamydiosis were analyzed. The frequency of C. psittaci was 12.54% and 7.89% in Psittaciformes and Columbiformes, respectively. A 348 bp region of the ompA gene was sequenced in positive samples. Molecular genotyping was performed through a Bayesian phylogenetic analysis. Of the 983 bird samples, 83 were positive for C. psittaci and 44 could be sequenced. The genotypes found were A, B, and E. Despite the high levels of host specificity, we found six psittacids with genotype B and one pigeon with genotype A, reflecting the affiliative interaction between Psittaciformes and Columbiformes. This study represents the first survey reporting the presence of C. psittaci in birds within the largest and most populous city in Argentina.<\/jats:p>","DOI":"10.3390\/ani14223286","type":"journal-article","created":{"date-parts":[[2024,11,14]],"date-time":"2024-11-14T09:14:31Z","timestamp":1731575671000},"page":"3286","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Molecular Detection and Genotyping of Chlamydia psittaci in Birds in Buenos Aires City, Argentina"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2389-1956","authenticated-orcid":false,"given":"Mar\u00eda Julia","family":"Madariaga","sequence":"first","affiliation":[{"name":"Secci\u00f3n Serolog\u00eda y Pruebas Biol\u00f3gicas, Instituto de Zoonosis Luis Pasteur, Ciudad Aut\u00f3noma de Buenos Aires C1405DCD, Argentina"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0345-7861","authenticated-orcid":false,"given":"Diego Alfredo","family":"Caraballo","sequence":"additional","affiliation":[{"name":"Instituto de Ecolog\u00eda, Gen\u00e9tica y Evoluci\u00f3n de Buenos Aires, CONICET-Universidad de Buenos Aires, Ciudad Aut\u00f3noma de Buenos Aires C1428EHA, Argentina"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7743-1795","authenticated-orcid":false,"given":"Mar\u00eda Luisa","family":"Teijeiro","sequence":"additional","affiliation":[{"name":"Secci\u00f3n Serolog\u00eda y Pruebas Biol\u00f3gicas, Instituto de Zoonosis Luis Pasteur, Ciudad Aut\u00f3noma de Buenos Aires C1405DCD, Argentina"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8535-0306","authenticated-orcid":false,"given":"Eduardo Jorge","family":"Boeri","sequence":"additional","affiliation":[{"name":"Secci\u00f3n Serolog\u00eda y Pruebas Biol\u00f3gicas, Instituto de Zoonosis Luis Pasteur, Ciudad Aut\u00f3noma de Buenos Aires C1405DCD, Argentina"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mar\u00eda Estela","family":"Cadario","sequence":"additional","affiliation":[{"name":"Servicio Bacteriolog\u00eda Cl\u00ednica, INEI-ANLIS \u201cDr. Carlos G.
