Varley CD, Rogers LM, Dixon BR, Bernard SC, Lacy DB, Sulpizio E, Aronoff DM, Townes JM. Persistent bacteremia and psoas abscess caused by a lethal toxin-deficient Paeniclostridiumsordellii. Anaerobe. 2022 Jan 24. 102520 p. PMID: 35085782 [PubMed]
We 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.
