Abstract：
We present a case of Raoultella planticola (R. planticola) infection that resulted in community-acquired pneumonia in an immunocompetent patient with an eight-week history of productive cough. This gram-negative bacterium is typically found in the environment and has the potential to infect humans. Raoultella planticola infections in humans have been recorded in several case reports from throughout the world in recent years, usually affecting immunocompromised patients. Although R. planticola is sensitive to most antibiotic groups, recent studies have revealed an increase in the infrequent acquisition of resistance genes in R. planticola, such as carbapenem resistance, making this pathogen a potential emergent threat. Our patient acquired R. planticola pneumonia in the absence of any underlying risk factors, making this the first case in the UK of R. planticola causing community-acquired pneumonia in an immunocompetent person.
摘要：
我们介绍了一例扁平Raoultella（R。planticola）感染，导致免疫功能正常的患者有8周的生产性咳嗽史，导致社区获得性肺炎。这种革兰氏阴性细菌通常在环境中发现，并有可能感染人类。近年来，在世界各地的几例病例报告中都记录了人类的扁平Raoultella感染，通常影响免疫功能低下的患者。虽然R.planticola对大多数抗生素组敏感，最近的研究表明，在R.planticola中很少获得抗性基因的增加，如碳青霉烯抗性，使这种病原体成为潜在的紧急威胁。我们的患者在没有任何潜在危险因素的情况下获得了R.planticola肺炎，这使其成为英国首例R.planticola引起免疫功能正常的人社区获得性肺炎的病例。
