Rods of the Acinetobacter genus are present mainly in the external environment (e.g. water, soil) and in animals, while in humans they may comprise physiological flora. The main pathogenic species is Acinetobacter baumannii complex, which constitutes a common cause of nosocomial infections, particularly in patients with underlying diseases and risk factors (e.g. prior broad-spectrum antibiotic therapy, malignancy, central venous catheter, mechanical ventilation); however, infections of the eye caused by strains of Acinetobacter spp. are very rare. We report a unique case of community-acquired corneal ulcer caused by Acinetobacter non-baumannii (possibly A. junii), in a patient with no risk factors identified. The case highlights the need for obtaining a sample from the cornea for bacteriological culture in the case of suspected ophthalmic infection as identification of the pathogen, and assessment of its susceptibility profile enables proper antibiotic therapy, improves the outcome and may constitute an eyesight-saving management.
不动杆菌属的杆菌主要存在于外部环境(如水、土壤)和动物中,而在人类中它们可能构成生理性菌群。主要的致病菌种是鲍曼不动杆菌复合体,它是医院感染的常见原因,尤其是在有基础疾病和危险因素的患者中(如先前的广谱抗生素治疗、恶性肿瘤、中心静脉导管、机械通气);然而,不动杆菌属菌株引起的眼部感染非常罕见。我们报告了一例由非鲍曼不动杆菌(可能是琼氏不动杆菌)引起的社区获得性角膜溃疡的独特病例,该患者未发现危险因素。该病例强调了在疑似眼部感染时从角膜获取样本进行细菌培养的必要性,因为病原体的鉴定及其药敏谱的评估能够进行适当的抗生素治疗,改善治疗结果,并可能构成挽救视力的处理措施。
