    The alpha-toxin is one of the virulence factors of Clostridium perfringens for gas gangrene in humans and animals or necrotic enteritis in poultry. The C-terminal domain of this toxin ( cpa 247-370 ) was synthesized and cloned into pT1NX vector to construct the pT1NX-alpha plasmid. This surface-expressing plasmid was electroporated into Lactobacillus casei ATCC 393, generating the recombinant L. Read More

    Clostridium perfringens alpha-toxin (ATX) is considered as a prototype of cytotoxic bacterial phospholipases C, and is the major virulence factor in C. perfringens-induced gas gangrene. It is known that, depending on the dose, ATX causes membrane disruption and cytolysis or only limited hydrolysis of its substrates. Read More

    Role of p38alpha/beta MAP Kinase in Cell Susceptibility to Clostridium sordellii Lethal Toxin and Clostridium difficile Toxin B.
    Toxins (Basel) 2016 Dec 22;9(1). Epub 2016 Dec 22.
    Institute for Toxicology, Hannover Medical School, Carl-Neuberg-Str. 1, D-30625 Hannover, Germany.
    Lethal Toxin from Clostridium sordellii (TcsL), which is casually involved in the toxic shock syndrome and in gas gangrene, enters its target cells by receptor-mediated endocytosis. Inside the cell, TcsL mono-O-glucosylates and thereby inactivates Rac/Cdc42 and Ras subtype GTPases, resulting in actin reorganization and an activation of p38 MAP kinase. While a role of p38 MAP kinase in TcsL-induced cell death is well established, data on a role of p38 MAP kinase in TcsL-induced actin reorganization are not available. Read More

    Fulminant Clostridium perfringens Sepsis in Kidney Transplant: A Case Report.
    Transplant Proc 2016 Nov;48(9):3112-3114
    Transplant Division, Department of Surgery, Indiana University School of Medicine, Indianapolis, Indiana.
    Background: Infections, particularly urinary tract infections, and cardiovascular accidents are the main causes of morbidity and mortality during the 1st year after kidney transplantation (KT). Bacteria and viruses, such as Escherichia coli, Enteroccoci, and Polyoma BK virus are common in the 1st 6 months, so they are controlled routinely. On the other hand, Clostridium perfringens infection is a rare life-threatening condition, associated with a high mortality rate especially in the transplant population, that is not controlled routinely.

    Soft Tissue Reconstruction Pyramid for the Diabetic Charcot Foot.
    Clin Podiatr Med Surg 2017 Jan 3;34(1):69-76. Epub 2016 Sep 3.
    Division of Podiatric Medicine and Surgery, Department of Orthopaedics, University of Texas Health Science Center San Antonio, 7703 Floyd Curl Drive, MSC 7776, San Antonio, TX 78229, USA.
    Foot and ankle ulcerations in patients with diabetic Charcot neuroarthropathy (DCN) occur frequently and can be challenging to address surgically when conservative care fails. Patients with acute or chronic diabetic foot ulcers (DFU) are at continued risk for development of osteomyelitis, septic arthritis, gas gangrene, and potential lower extremity amputation. Concurrent vasculopathy and peripheral neuropathy as well as uncontrolled medical comorbidities complicate the treatment approach. Read More

    Infection and Immunity Program, Biomedicine Discovery Institute and Department of Microbiology, Monash University, Clayton, VIC 3800, Australia.
    The ability of a pathogenic bacterium to scavenge iron from its host is important for its growth and survival during an infection. Our studies on C. perfringens gas gangrene strain JIR325, a derivative of strain 13, showed that it is capable of utilizing both human hemoglobin and ferric chloride, but not human holo-transferrin, as an iron source for in vitro growth.

    Lacking the 'protective label' of diabetes: Phenytoin-induced distal symmetrical peripheral neuropathy. A clinical case report.
    J Tissue Viability 2016 Nov 24;25(4):225-228. Epub 2016 Jun 24.
    Discipline of Podiatric Medicine, College of Medicine Nursing & Health Sciences, Aras Moyola, National University of Ireland Galway, Ireland. Electronic address:
    This report documents an unusual case of distal symmetrical peripheral neuropathy (DSPN) in an otherwise healthy patient without diabetes mellitus (DM) presenting to a podiatric wound care clinic. The development of gas gangrene coupled with Charcot neuroarthropathic changes ultimately resulted in a potentially life-saving transmetatarsal (TMT) amputation. Causation of, or at least a contributor to, the DSPN was likely phenytoin usage for epileptic seizures. Read More

    Analysis of the virulence-associated RevSR two-component signal transduction system of Clostridium perfringens.
    Int J Med Microbiol 2016 Sep 20;306(6):429-42. Epub 2016 May 20.
    Infection and Immunity Program, Biomedicine Discovery Institute and Department of Microbiology, Monash University, Clayton, Victoria 3800, Australia. Electronic address:
    Clostridium perfringens is a Gram-positive, anaerobic, spore-forming bacterium that causes human gas gangrene (clostridial myonecrosis) and food poisoning. Early studies showed that virulence was regulated by the VirSR two-component signal transduction system. However, our identification of the RevR orphan response regulator indicated that more than one system was involved in controlling virulence. Read More

    Massive gas gangrene secondary to occult colon carcinoma.
    Radiol Case Rep 2016 Jun 5;11(2):67-9. Epub 2016 Mar 5.
    Department of Radiology, Duke University Medical Center, DUMC Box 3808, Durham, NC 27710, USA.
    Gas gangrene is a rare but often fatal soft-tissue infection. Because it is uncommon and the classic symptom of crepitus does not appear until the infection is advanced, prompt diagnosis requires a high index of suspicion. We present a case report of a middle-aged man who presented with acute onset lower-extremity pain that was initially thought to be due to deep vein thrombosis. Read More

    RNA-seq analysis of virR and revR mutants of Clostridium perfringens.

    Infection and Immunity Program, Biomedicine Discovery Institute and Department of Microbiology, Monash University, Clayton, 3800, Australia.
    Background: Clostridium perfringens causes toxin-mediated diseases, including gas gangrene (clostridial myonecrosis) and food poisoning in humans. The production of the toxins implicated in gas gangrene, α-toxin and perfringolysin O, is regulated by the VirSR two-component regulatory system. In addition, RevR, an orphan response regulator, has been shown to affect virulence in the mouse myonecrosis model. Read More
