He presented to the hospital for treatment. Chest computed tomography (CT) showed a high-density shadow in the deep area of the left lower lung. Sputum culture returned negative. Empirical treatment with multiple antibiotics was given. No improvement was observed in the patient\u2019s condition. Next-generation sequencing (NGS) was performed on bronchoalveolar lavage fluid. It confirmed the diagnosis of\n                      <jats:italic>Chlamydia psittaci<\/jats:italic>\n                      infection. The lesion was located deeply. The clinical team promptly adjusted the antibiotic regimen. Intensive pulmonary rehabilitation training was added simultaneously. It facilitated the drainage of deep-seated sputum. The patient finally achieved complete recovery and was discharged.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>This case report indicates that in patients with high fever, clinicians should first determine the etiological factors and identify the lesion site. Accurate diagnosis can thus be achieved. In this case, the lesion was deeply located in the lung. Even with sensitive antibiotics, complete elimination of the lesion was difficult. Therefore, active pulmonary rehabilitation intervention should be implemented promptly. It promotes airway clearance, sputum excretion, and secretion drainage. It also accelerates the patient\u2019s recovery process.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.3389\/fmed.2026.1764616","type":"journal-article","created":{"date-parts":[[2026,3,27]],"date-time":"2026-03-27T05:19:49Z","timestamp":1774588789000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["Chlamydia psittaci pneumonia without cough: recovery, case report and literature review"],"prefix":"10.3389","volume":"13","author":[{"given":"Mingxuan","family":"Yang","sequence":"first","affiliation":[{"name":"Department of Rehabilitation Medicine, The Second Affiliated Hospital of Kunming Medical University, Kunming","place":["Yunnan, China"]},{"name":"Kunming Medical University, Kunming","place":["Yunnan, China"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xue","family":"Yang","sequence":"additional","affiliation":[{"name":"Department of Rehabilitation Medicine, The Second Affiliated Hospital of Kunming Medical University, Kunming","place":["Yunnan, China"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ying","family":"He","sequence":"additional","affiliation":[{"name":"Department of Rehabilitation Medicine, The Second Affiliated Hospital of Kunming Medical University, Kunming","place":["Yunnan, China"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Liqing","family":"Yao","sequence":"additional","affiliation":[{"name":"Department of Rehabilitation Medicine, The Second Affiliated Hospital of Kunming Medical University, Kunming","place":["Yunnan, China"]},{"name":"School of Rehabilitation, Kunming Medical University, Kunming","place":["Yunnan, China"]}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1965","published-online":{"date-parts":[[2026,3,27]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"262","DOI":"10.1647\/217-265","article-title":"Compendium of measures to control Chlamydia psittaci infection among humans (Psittacosis) and pet birds (Avian Chlamydiosis), 2017.","volume":"31","author":"Balsamo","year":"2017","journal-title":"J Avian Med Surg"},{"key":"B2","doi-asserted-by":"publisher","first-page":"e512","DOI":"10.1016\/S2666-5247(22)00064-7","article-title":"Human-to-human transmission of Chlamydia psittaci in China, 2020: an epidemiological and aetiological investigation.","volume":"3","author":"Zhang","year":"2022","journal-title":"Lancet Microbe"},{"key":"B3","doi-asserted-by":"publisher","first-page":"1","DOI":"10.1093\/femspd\/ftu016","article-title":"Chlamydia psittaci in ducks: a hidden health risk for poultry workers.","volume":"73","author":"Vorimore","year":"2015","journal-title":"Pathog Dis"},{"key":"B4","doi-asserted-by":"publisher","first-page":"1456","DOI":"10.1099\/jmm.0.001456","article-title":"Sixteen cases of severe pneumonia caused by Chlamydia psittaci in South China investigated via metagenomic next-generation sequencing.","volume":"70","author":"Xiao","year":"2021","journal-title":"J Med Microbiol."},{"key":"B5","doi-asserted-by":"publisher","first-page":"11","DOI":"10.1186\/s12879-024-10374-4","article-title":"Chlamydia psittaci pneumonia -
