Clostridium sordellii (C. sordellii) is an anaerobic gram-positive rod most commonly found in the soil and sewage but also as part of the normal flora of the gastrointestinal tract and vagina of a small percentage of healthy individuals. C. sordellii infection is considered to result from childbirth, abortion, and/or gynecological procedures. Although many strains of C. sordellii are nonpathogenic, virulent toxin-producing strains exist. Infection with this organism typically manifests as a patient experiencing septic shock rapidly followed by end-organ failure. Identification of C. sordelli has been successful by traditional culture, mass spectrometry methods, and via molecular methods. Herein, we present a fatal case of C. sordellii infection of a postpartum 33-year-old Asian woman. The organism was isolated by culture and identified using matrix-assisted laser desorption/ionization-time-of-flight (MALDI-TOF) technology. With the advent of rapid detection methods, antepartum screening for the fatal Clostridium species should be implemented in the general female population.
索氏梭菌(C. sordellii)是一种厌氧革兰氏阳性杆菌,最常见于土壤和污水中,但在一小部分健康个体的胃肠道和阴道正常菌群中也可发现。索氏梭菌感染被认为是由分娩、流产和/或妇科手术引起的。虽然许多索氏梭菌菌株无致病性,但存在产生毒性毒素的菌株。感染这种微生物通常表现为患者迅速出现感染性休克,随后出现终末器官衰竭。通过传统培养、质谱方法和分子方法已成功鉴定出索氏梭菌。在此,我们报告一例33岁亚洲产后妇女索氏梭菌感染致死病例。通过培养分离出该微生物,并使用基质辅助激光解吸/电离飞行时间(MALDI-TOF)技术进行鉴定。随着快速检测方法的出现,应在一般女性人群中开展对致命梭菌物种的产前筛查。
