Raoultella Planticola is a gram negative, aerobic, rod bacteria found in water and soil and is rarely reported to cause infections in humans. This case study is the first of its kind in reporting R. planticola appendicitis.
We report a case of a woman presenting with a two-day history of increased weakness, fatigue and anorexia, localized pain to the right lower quadrant, and elevated white blood cell count. CT results demonstrated acute uncomplicated appendicitis which was managed via laparoscopic appendectomy. The patient became febrile on the day of the procedure and was found to have R. planticola bacteremia which was treated with amoxicillin-clavulanate. She was discharged on postoperative day two and reported an unremarkable recovery at her five-week follow-up appointment.
R. planticola is a common organism that is rarely, though increasingly, associated with human infection. Interestingly, prior to hospitalization, this patient did not have any risk factors commonly associated with R. planticola infection, such as seafood consumption. However, she may have had gastrointestinal tract colonization with R. planticola prior to onset of appendicitis and appendectomy. Bacteremia likely resulted from micro-perforation of the appendix.
Although infection with R. planticola is typically benign when treated appropriately, this pathogen has homology with Klebsiella species, and has the potential to acquire antimicrobial resistance. The case presented here suggests that R. planticola should be considered as a potential source of bacteremia in inflammatory/infectious gastrointestinal tract diseases even in the absence of typical risk factors.
植生拉乌尔菌是一种革兰氏阴性需氧杆菌,存在于水和土壤中,很少有报道称其会导致人类感染。本病例研究是首例关于植生拉乌尔菌性阑尾炎的报道。
我们报告一例女性病例,患者有两天的虚弱、疲劳和厌食加重病史,右下腹局部疼痛,白细胞计数升高。CT结果显示为急性单纯性阑尾炎,通过腹腔镜阑尾切除术进行治疗。患者在手术当天发热,被发现患有植生拉乌尔菌血症,用阿莫西林-克拉维酸进行治疗。她在术后第二天出院,在五周的随访预约中报告恢复情况良好。
植生拉乌尔菌是一种常见的微生物,虽然与人类感染的关联越来越少,但仍时有发生。有趣的是,在住院之前,该患者没有任何通常与植生拉乌尔菌感染相关的危险因素,如食用海鲜。然而,在阑尾炎和阑尾切除术发病之前,她的胃肠道可能已经被植生拉乌尔菌定植。菌血症可能是由阑尾的微小穿孔引起的。
虽然适当治疗时,植生拉乌尔菌感染通常是良性的,但这种病原体与克雷伯菌属具有同源性,并且有可能获得抗菌药物耐药性。此处呈现的病例表明,即使没有典型的危险因素,在炎症性/感染性胃肠道疾病中,植生拉乌尔菌也应被视为菌血症的潜在来源。
