Acinetobacter spp. are one of the main pathogens responsible for healthcare-associated infections and are associated with high rates of morbidity and mortality globally, mainly because of their high capacity to present and develop resistance to antimicrobials. To identify species of the Acinetobacter and their resistance profiles from samples collected from hospitalized patients, health professionals and hospital environmental sources in the intensive care units of different public reference hospitals in Porto Velho City, Rondônia, Western Brazilian Amazon. Isolates were identified using microbiological and molecular techniques. The antimicrobial susceptibility profile was determined by disk diffusion. A total of 201 Acinetobacter spp. isolates were identified, of which 47.3% originated from hospital structures, 46.8% from patients and 6% from healthcare professionals. A. baumannii and A. nosocomialis were the most prevalent, with frequency of 58.7% and 31.8%, respectively. Regarding the susceptibility profile, it was observed that 56.3% were classified as multidrug-resistant and 76.2% of the samples belonging to A. baumannii were resistant to carbapenems. In contrast, 96.9% were susceptible to polymyxin B and 91.3% to doxycycline. The data presented here can be used to guide and strengthen the control of multidrug-resistant infections caused by Acinetobacter spp., in addition to improving providing information from a traditionally unassisted region of Brazil.

不动杆菌属 是导致医疗保健相关感染的主要病原体之一，并与全球高发病率和死亡率相关，主要是因为它们对抗菌药物产生和产生耐药性的能力很强。从巴西亚马逊西部朗多尼亚州波多韦柳市不同公立参考医院重症监护病房的住院患者、卫生专业人员和医院环境来源收集的样本中鉴定不动杆菌的种类及其耐药性概况。使用微生物学和分子技术鉴定分离株。通过纸片扩散测定抗菌敏感性曲线。共有201个不动杆菌属。已鉴定出分离株，其中 47.3% 来自医院机构，46.8% 来自患者，6% 来自医疗保健专业人员。鲍曼不动杆菌和院内不动杆菌最为常见，频率分别为 58.7% 和 31.8%。关于药敏情况，观察到 56.3% 的鲍曼不动杆菌样品具有多重耐药性，76.2% 的鲍曼不动杆菌样品对碳青霉烯类药物具有耐药性。相比之下，96.9% 的人对多粘菌素 B 敏感，91.3% 的人对多西环素敏感。除了改进巴西传统上不受援助地区的信息提供外，此处提供的数据还可用于指导和加强对不动杆菌属引起的多重耐药感染的控制。
