INTRODUCTION: Clostridium (C) perfringens and Klebsiella (K) oxytoca are pathogenous human bacteria. Due to the production of several toxins C. perfringens is virulent by causing i.a. the necrotizing fasciitis, gas gangrene and hepatic abscess. K. oxytoca mostly causes infections of the respiratory and gastrointestinal tract. PRESENTATION OF CASE: We are presenting the case of a male patient at the age of 64, who suffered from nausea and progressive pain in the right upper abdomen...

Uterine gas gangrene caused by Clostridium perfringens is a serious, often life-threatening infection that is rarely encountered in the practice of gynecologic oncology. However, the hypoxic nature of gynecologic cancers due to necrosis and/or prior radiation therapy creates a microenvironment optimal for proliferation of anaerobic bacteria such as the Clostridium species. Early recognition and aggressive treatment with IV antibiotics and surgical debridement remain the cornerstones of management in order to decrease morbidity and mortality...

Metalloproteases are a class of proteases having metal ion(s) at their catalytic sites. Bacterial collagenases are involved in human gas gangrene, periodontal diseases, food etc. The Clostridium collagenase occurs in two isoforms COL_G and Col_H. The present work is based on the protein structure-based approach for the development of collagenase inhibitor. The sequence analysis and structural alignment of both isoforms showed significant similarity in active site except aspartate switch present in Col_H. The homology model was developed and validated for Col_H peptidase domain with open aspartate switch followed by the docking of designed ligands...

Fournier's gangrene is a gas-forming, necrotising soft tissue infection affecting the perineum. It spreads rapidly along the deep fascial planes and is associated with a high mortality rate. With a growing elderly population with comorbidities, the frequency of severe cases of Fournier's gangrene is expected to increase. We retrospectively reviewed 20 patients diagnosed with Fournier's gangrene at our institution from 2003 to 2014 and analysed data. Thirteen patients had diabetes mellitus, two had been diagnosed with liver cirrhosis, and four were chronic alcoholics...

Gas gangrene is one of the most serious infections of traumatic and surgical wounds. The importance lies in the fact that, if not managed at the right time, the condition is fatal. Though perianal cellulitis and gangrene are commonly reported in immunocompromised patients, we report the case of a patient with gas gangrene involving only the anal canal extending to the rectum, a rare presentation to be reported in literature.  An 18-year-old lady, a patient of aplastic anaemia - immunodeficiency, developed gas gangrene of the anal canal possibly due to faecal contamination of anal fissures...

Snakebite is a common, frequently devastating, occupational, socio-economic hazard, and it has a great impact on the rural population of India. Snakebite is a major cause of the human morbidity and mortality since ancient times, as it not only affects the victim by systemic envenomation but also by wound infections originating from deadly pathogenic microorganisms from the oral cavity of the offending snake. The pathogens from the oral cavity of the snake tend to initiate an infection, resulting in gas gangrene, soft tissue necrosis, and permanent physical disabilities...

Blood serum from immunized humans or animals (e.g., horses) contains relevant antibodies and has been used as serum therapy to treat many diseases or envenomation events. The effectiveness of blood serum was initially discovered in 1890 when Kitasato and von Behring observed the effectiveness of this type of therapy against diphtheria and tetanus. Serum therapies played an important role in the advancement of modern medicine prior to the development of penicillin and steroids. At present, several types of serum therapy remain in clinical use...

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. casei strain expressing alpha-toxoid (LC-α strain). Expression of this modified alpha-toxoid was confirmed by SDS-PAGE, immunoblotting, and direct immunofluorescence microscopy...
