Persistent bacteremia and psoas abscess caused by a lethal toxin-deficient Paeniclostridiumsordellii. Anaerobe. 2022;75:102520. doi:10.1016/j.anaerobe.2022.102520https://hdl.handle.net/1805/43521We present a case of persistent bacteremia and psoas abscess from Paeniclostridium sordellii without severe symptoms or the classically associated toxic shock syndrome. Further laboratory evaluation demonstrated that the Paeniclostridium sordellii isolate lacked the lethal toxin gene and there was no cytotoxicity to exposed Vero cells.en-USPublisher PolicyBacteremiaBacterial toxinClostridium sordelliiClostridium speciesGram-positive bacilliPaeniclostridium sordelliiArticle
