Pseudomonas stutzeri is distributed widely in the environment, and occupies different ecological niches. However, it is found in clinically relevant infections as an opportunistic pathogen. Isolation of P. stutzeri from an odontogenic inflammatory cyst is an uncommon microbiological finding that has not been reported to date. In the case presented here, the bacterium was isolated from surgical material obtained from excision of an inflammatory odontogenic cyst located in the tooth 1.2, and presenting with concomitant pulp necrosis. Complementary techniques such as radiographs, CAT scans, and histopathological and microbiological studies were used to establish definitive diagnosis. The obtained results allowed classifying the process as an inflammatory cyst infected by P. stutzeri. Biotyping and characterization of the susceptibility profile of the isolated strain allowed adjusting the antibiotic therapy more specifically. The microbiological studies allowed establishing the etiology of the infectious process, adjusting the treatment plan, and re-establishing tissue integrity.
斯氏假单胞菌广泛分布于环境中，占据不同的生态位。然而，它作为一种机会致病菌可在临床相关感染中被发现。从牙源性炎性囊肿中分离出斯氏假单胞菌是一项罕见的微生物学发现，迄今为止尚未见报道。在本文所述病例中，该细菌是从位于1.2号牙的炎性牙源性囊肿切除术中获得的手术材料中分离出来的，该囊肿伴有牙髓坏死。采用了X光片、计算机断层扫描以及组织病理学和微生物学研究等辅助技术来进行明确诊断。所获结果使该病程被归类为由斯氏假单胞菌感染引起的炎性囊肿。对分离菌株进行生物分型和药敏谱特征分析有助于更精准地调整抗生素治疗方案。微生物学研究有助于确定感染病程的病因，调整治疗方案，并恢复组织完整性。
