摘要

本文报道了1例脲放线杆菌（Actinobacillus ureus）引起恶性肿瘤患者肺部感染的病例，并进行文献复习。该患者在住院化疗期间机体免疫功能低下时，机会性感染了脲放线杆菌，引起了典型的肺部炎症。在诊治过程中与临床医生及时沟通，对致病菌及时进行药敏试验，指导临床对患者规范用药。使用头孢哌酮舒巴坦联合左氧氟沙星静脉滴注进行抗感染对症治疗后，患者肺部炎症明显好转。文献显示脲放线杆菌的感染率明显高于临床的认知水平，因此在临床实践中应将其视为易感患者的潜在病原体。本病例通过对1例脲放线杆菌机会性感染导致的肺部炎症进行报道，以提高实验室工作人员对该病原体的认知，为临床医生及时诊治少见病原体的感染提供参考。

Abstract

This article reports a case of pulmonary infection caused by Actinobacillus ureus in a patient with a malignant tumor and a literature review. This patient was infected with Actinobacillus ureus during hospitalisation for chemotherapy when the body's immune function was low. We communicated with clinicians during the testing process, performed drug susceptibility testing according to clinical needs, and assisted in the clinical treatment of the patient using cefoperazone sulbactam in combination with intravenous levofloxacin for anti-infective symptomatic treatment. Although Ureaplasma actinomycetemcomitans is generally recognised as a normal flora of the respiratory tract in clinical practice, the prevalence of infection with this organism is higher than the general level of recognition, according to the available literature; therefore, it should be regarded as a potential pathogen in susceptible patients in clinical practice. In this case, the laboratory characteristics and clinical manifestations of Actinobacillus ureus were studied and researched to increase the knowledge of medical practitioners about this pathogen, and to provide clinicians with a reference for the diagnosis of this type of disease.
