鹦鹉热衣原体是一种胞内寄生的革兰阴性菌，可引发人畜共患病。鹦鹉热衣原体感染多表现为呼吸道症状，在中枢神经系统受累时通常表现为脑膜炎、颅神经麻痹、吉兰巴雷综合征以及癫痫。本文介绍了1例鹦鹉热衣原体致重症肺炎且合并颅神经损害的病例，经过多西环素抗感染治疗后肺部感染及颅神经病变好转。该病例报告不仅帮助临床医师进一步熟悉鹦鹉热衣原体感染累及中枢神经系统的临床表现，更有助于其了解鹦鹉热病原体目前的诊断手段。

Chlamydia psittaci, an intracellular gram-negative bacterium that commonly infects birds, causes psittacosis in humans. Psittaci is commonly cause pneumonia, and neurological complications in psit-tacosis are rare. Psittacosis associated neurological complications include meningitis, cranial nerve palsy, Guillain-Barre Syndrome and epilepsy. We present a case study on cranial nerve palsies and severe pneumonia associated with psittacosis. Doxycycline was resumed, and the patient made a full recovery. This case report not only helps clinicians familiarize the clinical manifestations of Chlamydia psittaci infection involving the central nervous system, but also helps to understand the current diagnostic methods of the psittacosis pathogen.
