目的 探究肺泡灌洗液靶向高通量测序（tNGS）在鹦鹉热衣原体肺炎中应用效果。方法 选取2021年5月—2025年3月我院收治的35例鹦鹉热衣原体肺炎患者进行研究，患者均接受肺泡灌洗液tNGS检测、肺泡灌洗液常规病原检测，以病原学为金标准，分析肺泡灌洗液tNGS对鹦鹉热衣原体肺炎的诊断效能。结果 金标准对鹦鹉热衣原体阳性检出35例，检出率100.00%，肺泡灌洗液tNGS阳性检出率高于传统病原检测，检测结果回报耗时短于肺泡灌洗液传统病原检测（P＜0.05）。结论 鹦鹉热衣原体肺炎临床症状缺乏特异性，容易转为重症肺炎，肺泡灌洗液tNGS可提高鹦鹉热衣原体肺炎检出率且结果回报较快，采用四环素类、喹诺酮类抗生素有助于改善患者预后。

     Objective To investigate the application effect of targeted next-generation sequencing（tNGS）of bronchoalveolar lavage fluid（BALF）in Chlamydia psittaci pneumonia．Methods Thirty-five patients with Chlamydia psittaci pneumonia admitted to our hospital from May 2021 to March 2025 were selected for the study．All patients underwent BALF tNGS and conventional BALF pathogen detection．With etiology as the gold standard，the diagnostic efficacy of BALF tNGS for Chlamydia psittaci pneumonia was analyzed．Results The gold standard detected 35 cases of Chlamydia psittaci positive，with a detection rate of 100.00%．The positive detection rate of tNGS in alveolar lavage fluid was higher than that of traditional pathogen detection，and the results report time of tNGS was shorter than that of traditional pathogen detection（P＜0.05）．Conclusions Chlamydia psittaci pneumonia lacks specificity in clinical symptoms and is easy to turn into severe pneumonia，bronchoalveolar lavage fluid tNGS can improve the detection rate of Chlamydia psittaci pneumonia and the results return quickly，and the use of tetracyclines and quinolones antibiotics can help improve the prognosis of patients．
