is a Gram-negative bacillary bacterium known for its multidrug resistance, particularly to carbapenems. This resistance complicates treatment and results in a high mortality rate, especially in hospitalized patients, which can reach up to 52 %. In this case, the infection was observed in a 73-year-old immunocompetent patient with a chronic exacerbated subdural hemorrhage with midline deviation and tracheostomy, who was hospitalized and febrile, and the bacterium was isolated in bronchial secretion cultures. The patient responded favorably to treatment with sulfamethoxazole/trimethoprim and other recurrent infections caused by , and . Ultimately, the immunocompetent patient improved and was discharged, able to ventilate independently.
是一种革兰氏阴性杆菌，以其多重耐药性而闻名，尤其是对碳青霉烯类药物耐药。这种耐药性使治疗变得复杂，并导致高死亡率，尤其是在住院患者中，死亡率可达52%。在该病例中，一名73岁免疫功能正常的患者出现慢性加重性硬膜下血肿伴中线移位并进行了气管切开术，住院期间发热，在支气管分泌物培养中分离出该细菌。患者对磺胺甲恶唑/甲氧苄啶治疗反应良好，且未出现由该细菌及其他细菌引起的反复感染。最终，该免疫功能正常的患者病情好转并出院，能够自主通气。
