Clostridium Sordellii as an Uncommon Cause of Fatal Toxic Shock Syndrome in a Postpartum 33-Year-Old Asian Woman, and the Need for Antepartum Screening for This Clostridia Species in the General Female Population.

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. © American Society for Clinical Pathology, 2016.
