Abstract：
Bacterial pneumonia causes significant morbidity and mortality especially in elderly and immunocompromised hosts. Achromobacter xylosoxidans denitrificans pneumonia is very rarely reported. However, the reported cases have been in patients who are either immunocompromised or have bronchiectasis. We hereby present a unique case of Achromobacter xylosoxidans denitrificans pneumonia in an immunocompetent patient with advanced chronic obstructive pulmonary disease (COPD). Our patient is a Caucasian male admitted with shortness of breath, fever and cough. Chest X-ray demonstrated right-sided infiltrates and he was treated with intravenous ceftriaxone and azithromycin. He was discharged home on oral amoxicillin-clavulanate 875-125 mg two times per day for a total of 7 days. Patient returned to emergency room after 5 weeks with persistent symptoms and chest X-ray revealed persistent right-sided infiltrate and sputum culture showed Achromobacter xylosoxidans denitrificans. The patient was started on oral levofloxacin 750 mg one time per day for 2 weeks with resolution of symptoms.
摘要：
细菌性肺炎引起显著的发病率和死亡率,尤其是在老年人和免疫受损的宿主中。很少报道木糖氧显色杆菌反硝化杆菌肺炎。然而,报告的病例是免疫功能低下或支气管扩张的患者。在此，我们介绍了患有晚期慢性阻塞性肺疾病（COPD）的免疫功能正常的患者中的木氧化杆菌脱氮杆菌肺炎的独特病例。我们的病人是一名高加索男性，因呼吸急促入院，发烧和咳嗽。胸部X光检查显示右侧浸润，他接受了头孢曲松和阿奇霉素静脉注射治疗。他每天两次口服阿莫西林-克拉维酸875-125mg出院，共7天。5周后，患者因症状持续而返回急诊室，胸部X光检查显示持续右侧浸润，痰液培养显示木氧嗜铬杆菌。患者开始口服左氧氟沙星750mg，每天一次，持续2周，症状缓解。
