Large Clostridial Toxins: Mechanisms and Roles in Disease.

Microbiol Mol Biol Rev 2021 Jun 2:e0006421. Epub 2021 Jun 2.

Molecular Medicine Program, The Hospital for Sick Children Research Institute, Toronto, Ontario, Canada.

Large clostridial toxins (LCTs) are a family of bacterial exotoxins that infiltrate and destroy target cells. Members of the LCT family include Clostridioides difficile toxins TcdA and TcdB, Paeniclostridium sordellii toxins TcsL and TcsH, Clostridium novyi toxin TcnA, and Clostridium perfringens toxin TpeL. Since the 19th century, LCT-secreting bacteria have been isolated from the blood, organs, and wounds of diseased individuals, and LCTs have been implicated as the primary virulence factors in a variety of infections, including C.

Rapidly progressive and fatal distant spontaneous gas gangrene due to after biopsy of malignant cecal mass.

IDCases 2021 22;24:e01129. Epub 2021 Apr 22.

University of California, San Francisco, 155 N Fresno St, Suite 307, Fresno, CA, 93701, United States.

species are known to cause myonecrosis and gas gangrene which are often fatal infections in the setting of trauma but also spontaneously in certain populations such as colorectal malignancy, immunosuppression, and neutropenia. We report a case of an 83-year-old male who developed fatal and rapidly progressive gas gangrene due to within 48 h after biopsy of suspected malignant cecal mass. To our knowledge, such a drastic, rapid and fatal presentation after a diagnostic biopsy of malignant mass has not been previously reported and is something to be watchful for in suspected colon cancer cases.

Pathogenicity and virulence of .

is an extremely versatile pathogen of humans and livestock, causing wound infections like gas gangrene (clostridial myonecrosis), enteritis/enterocolitis (including one of the most common human food-borne illnesses), and enterotoxemia (where toxins produced in the intestine are absorbed and damage distant organs such as the brain). The virulence of this Gram-positive, spore-forming, anaerobe is largely attributable to its copious toxin production; the diverse actions and roles in infection of these toxins are now becoming established. Most toxin genes are encoded on conjugative plasmids, including the pCW3-like and the recently discovered pCP13-like plasmid families. Read More

Trauma Case Rep 2021 Apr 18;32:100469. Epub 2021 Mar 18.

Department of Health Studies, University of Zadar, Croatia.

Gas gangrene is infectious disease caused by infection. We are presenting extremely rare case of gluteal clostridial myonecrosis after intramuscular injection of diclofenac in immunocompromised young patient on a long-standing corticosteroid therapy presented with sepsis and initially absent clinical signs of severe anaerobic infection. After delayed diagnosis, she was treated with aggressive surgical removal of necrosed tissue and targeted antibiotic therapy which led to a rapid improvement allowing application of a negative-pressure wound therapy device with favorable outcome.

Department of Microbiology, Faculty of Pharmaceutical Sciences, Tokushima Bunri University, Yamashiro-cho, Japan.

Toll-like receptor 4 (TLR4) has been reported to protect against Gram-negative bacteria by acting as a pathogen recognition receptor that senses mainly lipopolysaccharide (LPS) from Gram-negative bacteria. However, the role of TLR4 in Gram-positive bacterial infection is less well understood. type A is a Gram-positive bacterium that causes gas gangrene characterized by severe myonecrosis. Read More

Intratumoral Injection of -NT Spores in Patients with Treatment-refractory Advanced Solid Tumors.

Clin Cancer Res 2021 Jan 12;27(1):96-106. Epub 2020 Oct 12.

BioMed Valley Discoveries Inc., Kansas City, Missouri.

Purpose: Intratumorally injected -NT (nontoxic; lacking the alpha toxin), an attenuated strain of , replicates within hypoxic tumor regions resulting in tumor-confined cell lysis and inflammatory response in animals, which warrants clinical investigation.

Patients And Methods: This first-in-human study (NCT01924689) enrolled patients with injectable, treatment-refractory solid tumors to receive a single intratumoral injection of -NT across 6 dose cohorts (1 × 10 to 3 × 10 spores, 3+3 dose-escalation design) to determine dose-limiting toxicities (DLT), and the maximum tolerated dose.

Results: Among 24 patients, a single intratumoral injection of -NT led to bacterial spores germination and the resultant lysis of injected tumor masses in 10 patients (42%) across all doses. Read More
