On the potential significance of the intrinsically disordered regions in the Clostridiodes difficile toxins A and B.

Curr Protein Pept Sci 2022 May 18. Epub 2022 May 18.

Department of Molecular Medicine, Morsani College of Medicine, University of South Florida, Tampa, FL 33612, USA.

Background: Clostridiodes (or Clostridium) difficile is a spore-forming, Gram-positive anaerobic bacterium which may cause symptoms ranging from diarrhea to pseudomembranous colitis. During the C. difficile infection (CDI), the two primary bacterial toxins, toxin A (TcdA) or toxin B (TcdB), disrupt host cell function mainly through the inactivation of small GTPases that regulate the actin cytoskeleton.

Clostridium difficile infection after ileostomy closure and anastomotic failure in rectal cancer surgery patients.

BJS Open 2022 Mar;6(2)

Division of Colon and Rectal Surgery, Department of Surgery, University of Ulsan College of Medicine and Asan Medical Center, Seoul, Republic of Korea.

Background: Diverting ileostomy during resection of rectal cancer is frequently performed in patients at risk of anastomotic failure. Clostridium difficile infection (CDI) is reported to be frequent in patients who receive ileostomy closure with a questionable association to postoperative anastomosis leak. The primary aim of this study was to determine the incidence of CDI following ileostomy closure in patients who underwent rectal cancer surgery; the secondary aim was to assess the rate of postileostomy closure CDI in patients who presented with leakage at the original colorectal anastomosis site.

SEASON GAP score: A predictor of Clostridioides difficile infection among patients with tube feeding.

J Infect Chemother 2022 Apr 16. Epub 2022 Apr 16.

Department of Infectious Diseases, St. Luke's International Hospital: 9-1, Akashi-cho, Chuo-ku, Tokyo, 104-8560, Japan.

Introduction: Clostridioides difficile infection (CDI) is an important community- and hospital-acquired infection. Patients receiving tube feeding often have diarrhoea, and it is still unclear whether the traditional criteria for submitting samples for Clostridioides difficile (CD) testing as determined by the frequency of the diarrhoea apply to these patients.

Methods: We conducted a retrospective study comparing the clinical features of tube-fed inpatients with suspected CDI, with CDI, and those without CDI admitted between 2004 and 2020. Read More

Regulatory transcription factors of pathogenesis with a focus on toxin regulation.

Crit Rev Microbiol 2022 Apr 7:1-16. Epub 2022 Apr 7.

Department of Molecular Medicine, Morsani College of Medicine, University of South Florida, Tampa, FL, USA.

(CD), a nosocomial gut pathogen, produces two major exotoxins, TcdA and TcdB, which disrupt the gut epithelial barrier and induce inflammatory/immune responses, leading to symptoms ranging from mild diarrhoea to pseudomembranous colitis and potentially to death. The expression of toxins is regulated by various transcription factors (TFs) which are induced in response to CD physiological life stages, nutritional availability, and host environment. This review summarises our current understanding on the regulation of toxin expression by TFs that interconnect with pathways of flagellar synthesis, quorum sensing, motility, biofilm formation, sporulation, and phase variation.

Institute for Toxicology, Hannover Medical School, Hannover, Germany.

infection (CDI) in humans causes pseudomembranous colitis (PMC), which is a severe pathology characterized by a loss of epithelial barrier function and massive colonic inflammation. PMC has been attributed to the action of two large protein toxins, Toxin A (TcdA) and Toxin B (TcdB). TcdA and TcdB mono-O-glucosylate and thereby inactivate a broad spectrum of Rho GTPases and (in the case of TcdA) also some Ras GTPases. Read More
