Gas gangrene is a condition where anaerobic bacteria release toxins that cause tissue death, and if not treated can be fatal. Gas gangrene is typically an infection of muscle tissue and a characteristic sign of infection is the presence of blisters that bubble with gas near infected areas. There are fewer than 3,000 cases in the United States annually. In this article you will find out more about gas gangrene symptoms and whether there have been historical outbreaks of gas gangrene.

Clostridial gas gangrene is a highly lethal necrotizing soft tissue infection of skeletal muscle caused by toxin- and gas-producing Clostridium species. The synonym clostridial myonecrosis better describes both the causative agent and the target tissue.

Gas gangrene is caused by exotoxin-producing Clostridium species (most often C. perfringens, and C. novyi,[5] but less commonly C. septicum[6] or C. ramnosum),[7] which are mostly found in soil, but also found as normal gut flora, and other anaerobes (e.g., Bacteroides and anaerobic streptococci). The exotoxin is commonly found in C. perfringens type A strain and is known as alpha toxin. This alpha toxin is a lethal toxin and also known as phospholipase C (lecithinase). It increases vascular permeability and produces necrotizing activity. These environmental bacteria may enter the muscle through a wound and go on to proliferate in necrotic tissue and secrete powerful toxins. These toxins destroy nearby tissue, generating gas at the same time.. Other organisms may occasionally cause gas gangrene (for example, Klebsiella pneumoniae in the context of diabetes).[8]. A gas composition of 5.9% hydrogen, 3.4% carbon dioxide, 74.5% nitrogen, and 16.1% oxygen was reported in one clinical ...

Gas gangrene, or clostridial myonecrosis, is usually caused by Clostridium perfringens and may occur spontaneously in association with diabetes mellitus, peripheral vascular disease, or some malignancies but more often after contamination of a deep surgical or traumatic lesion. If not controlled, clostridial myonecrosis results in multiorgan failure, shock, and death... ...

For clostridial myositis and myonecrosis (gas gangrene) or spreading clostridial cellulitis with systemic toxicity (or a presumptive diagnosis of either) the preferred treatment is a combination of hyperbaric oxygen (HBO2), surgery, and antibiotics.. Clostridial myositis and myonecrosis or gas gangrene is an acute, rapidly progressive, non-pyogenic, invasive clostridial infection of the muscles, characterized by profound toxemia, extensive edema, massive death of tissue, and a variable degree of gas production.. Gas gangrene is either an endogenous infection, caused by contamination from a clostridial focus in the body, or an exogenous infection, mostly in patients with compound and/or complicated fractures with extensive soft tissue injuries after street accidents.. The infection is caused by anaerobic, spore‑forming, Gram‑ positive encapsulated bacilli of the genus clostridium, discovered by William H. Welch in 1891. More than 150 species of clostridium have been recognized but the most ...

Spore-forming bacteria are the causative agents of some of the most dramatic life-threatening human and animal infections and toxemias, including diseases such as tetanus, botulism, gas gangrene, pseudomembranous colitis, and anthrax. This chapter reviews the current state of knowledge of virulence plasmids of the Clostridia and the bacilli. Although other pathogens are mentioned, the focus is on the major human pathogens, Clostridium perfringens and Bacillus anthracis, primarily because most is known about virulence plasmids in these species. The major toxins involved in C. perfringens type A-mediated gas gangrene, the α-toxin and perfringolysin O, together with other extracellular toxins such as collagenase and hyaluronidase, are chromosomally encoded. Along with tetanus, botulism, and gas gangrene, anthrax is one of the four classical diseases that are caused by spore-forming bacteria. Expression of the plasmid-determined toxin genes in Bacillus thuringiensis is coordinately regulated with the

Gas gangrene occurs as a result of infection by Clostridium species of bacteria that under anaerobic (low oxygen) conditions, produce toxins that cause the tissue death and associated symptoms. Gas gangrene generally occurs at the site of trauma or a recent surgical wound. The onset of gas gangrene is sudden and dramatic. Inflammation begins at the site of infection as pale to brownish-red extremely painful tissue swelling. Gas may be felt in the tissue as a crackly sensation when the swollen area is pressed with the fingers. The margins of the infected area expand so rapidly that changes are visible over a few minutes of time. The involved tissue is completely destroyed. Clostridia species of bacteria produce many different toxins, four of which (alpha, beta, epsilon, iota) are all fatal. In addition they cause tissue death (necrosis), destruction of blood (hemolysis), local decrease in circulation (vasoconstriction), and leaking on the blood vessels (increased vascular permeability). These ...

Clostridium perfringens (formerly known as C. welchii) is a Gram-positive, rod-shaped, anaerobic, spore-forming bacterium of the genus Clostridium. It is always present in nature and is a normal component of decaying vegetation, marine sediment, the intestinal tract of humans, other vertebrates, insects, and soil. It can be a human pathogen and also harmlessly ingested. Commonly it is encountered in infections as a component of the normal flora where it takes a minor role in the disease. Infections show some evidence of tissue necrosis, bacteremia, emphysematous cholecystitis, and gas gangrene, which is also known as clostridial myonecrosis. The toxin in gas gangrene is α-toxin which inserts into the plasma membrane of cells disrupting normal cellular function C. perfringens. Ingestion can lead to bacteria multiplying and leading to colic, diarrhea, and sometimes nausea. C. perfringens bacteria are the third-most-common cause of food-borne illness, with poorly prepared meat and poultry the ...

The action of HBO2 on clostridia (and other anaerobes) is based on the formation of O2 free radicals in the relative absence of free radical degrading enzymes, such as superoxide dismutases, catalases, and peroxidases. Van Unnik(20) showed that an O2 tension of 250 mmHg is necessary to stop alpha‑ toxin production. Although it does not kill all clostridia, it is bacteriostatic both in vivo and in vitro.(20-24) Tissue O2 measurements made by Schoemaker,(25) Kivisaari and Niinikoski,(26) and Sheffield(27) have shown that treatment with HBO2 at 3.0 atm abs is required to achieve tissue partial pressures above 300 mmHg. Free-circulating toxins and/or tissue‑ bound toxins are not affected by high O2 levels but they are rapidly detoxified by normal host factors.(9,21,28,29) If further toxin elaboration is prevented by the addition of hyperbaric oxygen, a very sick patient can rapidly be made non-toxic. The diagnosis of clostridial myonecrosis is based primarily on clinical data, supported by the ...

Extended subcutaneous emphysema was noted, with foul smelling areas of necrosis in most of biceps brachii and the flexors of the forearm. Broad resection of necrotic tissues of arm and forearm was done. Thorough mechanical irrigation of the affected area was performed using normal saline, hypertonic solutions and the Stryker irrigation-suction device. Approximating tension sutures were used and the wound was let to be healed by third intention [Figure ​2b]. Subsequently the patient was transferred to the intensive care unit. Cultures of tissue specimens obtained intraoperatively revealed Staphylococcus epidermidis, Clostridium perfringens and Staphylococcus aureus.. Postoperatively the patient remained in the intensive care unit intubated and in septic shock. The first postoperative day he developed acute renal failure attributed to myoglobinuria requiring hemodialysis. The second postoperative day his platelet count was decreased to 45Κ/μL and increased gradually the following days. ...

General Information: The species type strain, originally isolated from a human gas gangrene patient. Causative agent of gas gangrene. This genus comprises about 150 metabolically diverse species of anaerobes that are ubiquitous in virtually all anoxic habitats where organic compounds are present, including soils, aquatic sediments and the intestinal tracts of animals and humans. This shape is attributed to the presence of endospores that develop under conditions unfavorable for vegetative growth and distend single cells terminally or sub-terminally. Spores germinate under conditions favorable for vegetative growth, such as anaerobiosis and presence of organic substrates. It is believed that present day Mollicutes (Eubacteria) have evolved regressively (i.e., by genome reduction) from gram-positive clostridia-like ancestors with a low GC content in DNA. Known opportunistic toxin-producing pathogens in animals and humans. Some species are capable of producing organic solvents (acetone, ethanol, ...

Alpha toxin or alpha-toxin refers to several different protein toxins produced by bacteria. Alpha toxin may be: Staphylococcus aureus alpha toxin, a membrane-disrupting toxin that creates pores causing hemolysis and tissue damage. Clostridium perfringens alpha toxin, a membrane-disrupting toxin with phospholipase C activity, which is directly responsible for gas gangrene and myonecrosis. Pseudomonas aeruginosa alpha toxin ...

Three patients who were treated at the authors institutions for soft tissue Vibrio vulnificus infections of the lower extremities, underwent leg amputation. The infection occurred after penetrating injury of the lower extremities by spines of various fish. In three patients the injuries were incurred by spines of Drakaina fish and in one case by Cyprinus caprio fish. The first one is a common fish in Greece area, but the last one is a consumed fish, imported from other Mediterranean countries. Extensive soft tissue necrosis and amputation was performed in three cases, because of aggressive gas gangrene or septic complications. Although blood cultures were positive in all cases, no reccurent infection was detected after 3-6 years of follow up except in one patient. Unfortunatelly a reccurent inflammatory process with concomitant calcaneous osteo-myelitis was developed three years after the initial injury, in this case ...

You see it all the time in westerns - the wounded cowboy is biting down on a piece of leather and somebody is pouring his whiskey or moonshine (yowza) into his wound to clean it. But does it work. Actually, the answer is yes. It needs to be between 120 and 180 proof to be most effective.. You should know though, that many studies show that ethyl alcohol, the alcohol in liquor, doesnt kill some bacteria, including Clostridium, the bacteria responsible for tetanus, botulism, and gas gangrene. Still it kills most others, though it works slower than isopropyl alcohol.. So, if youve got the vodka or the whiskey and a wound that needs cleaning, bite down on the strop and pour it on. Since it has other uses such as making tinctures and drinking, its a good thing to have around.. ...

Dr. Alexander suggested that an important feature of these macabre medical experiments not only represented a ruthless and distorted pursuit of scientific goals but also elucidated sinister motivations with practical ulterior motives arising out of the requirements of serving under a totalitarian state. Within the Nazi hierarchy, there was fear, suspicion, rivalry, intrigue, and an internecine struggle within their ranks which the Germans euphemistically termed self-selection of leaders. For example, Dr. Gebhardt performed these grisly experiments to clear himself of the suspicion he had contributed to the death of SS General Reinhard Heydrich, The Hangman, either because of his own medical negligence or, deliberately, by failing to treat his wound with the advent of the new sulfonamide antibiotics. After Heydrich (who had been ambushed by Czech partisans) died from gas gangrene, Himmler told Dr. Gebhardt the only way he could clear himself from the possible repercussions of Heydrichs death ...

Project Summary:. Clostridium Difficile (c. diff) is a bacteria which causes much morbidity and mortality worldwide. It does so by causing diarrhea and abdominal pain. It can be mild and self-limited, to severe and lethal, even in developed countries. It can require removal of the colon to try to spare a victims life. This isnt always successful. Current treatment is withdrawal of any unnecessary antibiotics, addition of one of two antibiotics that work pretty reliably against c.diff, hydration, and observation for signs the patient might need to be operated.. The investigators propose that instead of trying to kill the bacteria that are a problem, with limited antibiotic choices, the investigators can give the patient a bowel prep and quickly and reliably wash the bacteria, and the toxin that actually wreaks the havoc, out of their system.. The investigators will collect variables of mortality, LOS, ICU days, surgical interventions (colectomy or ileostomy and lavage), time to test negative ...

When a gaseous substance is placed in a container and the volume of the container is decreased, the pressure exerted by the gas on the walls of the container increases. This implies that there is a specific relationship between the volume occupied by a gas and the pressure exerted by it. The Anglo-Irish chemist & physicist Robert Boyle studied this relationship and published his findings as an experimental gas law which is now known as Boyles law. The statement of this law can be written as:. The pressure exerted by an ideal gas is inversely proportional to the volume occupied by it as long as the absolute temperature of the gas and the number of moles of gaseous substance are kept constant. Boyles law can be expressed mathematically as:. P ∝ 1/V. Where P is the pressure exerted by the gas and V is the volume occupied by it. It is important to note that this law is sometimes referred to as the Boyle-Mariotte law or as Mariottes law. The English experimenter Henry Power and the English ...

The ocean is a major sink for anthropogenic carbon dioxide (CO2), with the CO2 uptake causing changes to ocean chemistry. To monitor these changes and provide a chemical background for biological and biogeochemical studies, high quality partial pressure of CO2 (pCO2) sensors are required, with suitable accuracy and precision for ocean measurements. Optodes have the potential to measure in situ pCO2 without the need for wet chemicals or bulky gas equilibration chambers that are typically used in pCO2 systems. However, optodes are still in an early developmental stage compared to more established equilibrator-based pCO2 systems. In this study, we performed a laboratory-based characterization of a time-domain dual lifetime referencing pCO2 optode system. The pCO2 optode spot was illuminated with low intensity light (0.2 mA, 0.72 mW) to minimize spot photobleaching. The spot was calibrated using an experimental gas calibration rig prior to deployment, with a determined response time (τ63) of 50 s at 25°C.

Anaerobic infection is an infectious process (often a complication of the wound process), caused by anaerobes. Among the pathogens A. and. Two groups of microorganisms are distinguished: spore-forming anaerobes, or clostridia, and non-spore-forming (nonclostridial) anaerobes (see Anaerobes). They are an integral part of normal human microflora, are found in the intestines, organs of the genitourinary system, as well as on the surface of the skin, mucous membranes. Anaerobes of exogenous flora are detected in the soil, in the mass of decomposing organic compounds. An important role is played by such factors as the amount of anaerobes in the wound, the morphology and virulence of the pathogens, the potentiating effect of the microbial associates, etc. Pathogenic properties of anaerobes are realized in the presence of deformed and practically devoid of blood supply of tissue sites, chronic intoxication, accompanied by a decrease in protective reactions of the organism, etc..

Za kalcijeve ione Ca2+ so prepustni nekateri živčni nikotinski receptorji, kar lahko sproži sproščanje drugih živčnih prenašalcev.[4] Kanalček se odpre hipoma in ostaja načeloma odprt, dokler agonist ostaja vezan na vezavno mesto, kar običajno traja okoli 1 milisekundo.[3] V redkih primerih pa se lahko kanalček spontano zapre kljub vezavi acetilholina ali pa se kljub odsotnosti liganda odpre. Zato vezava acetilholina zgolj poveča verjetnost odprtja kanalčka; več acetilholina se veže na receptor, večja je verjetnost, da se bo kanalček odprl.[11].

Gas gangrene or C. myonecrosis is a rare life-threatening illness that results in necrotising soft tissue injury. Early recognition and diagnosis is imperative as the disease course is rapid. Risk factors for developing fulminant soft tissue infections include trauma, immunosupression, diabetes and vascular disease. More specifically, gas gangrene is commonly associated with patients post surgery or trauma due to the presence of Clostridium perfringes. Only 16% of cases occur spontaneously and the organisms responsible is usually the more virulent C. septicum.1 2 Clostridium is an anaerobic, spore-forming, positive rod.2 It constitutes part of the normal flora of the gastrointestinal tract. There are over 100 different strains of Clostridium of varying clinical significance. C. septicum infection resulting in bacteraemia is extremely rare. Larson et al 3 reviewed all cases of Clostridium infection at their institution from 1966 to 1993. Among 241 cases of Clostridium, 32 cases were C. septicum ...

A collection of disease information resources and questions answered by our Genetic and Rare Diseases Information Specialists for Clostridium perfringens infection

Clostridium perfringens is a Gram-positive bacterium responsible for bacteremia, gas gangrene, and occasionally food poisoning. Its genome encodes three sialidases, nanH, nanI, and nanJ, that are involved in the removal of sialic acids from a variety of glycoconjugates and that play a role in bacterial nutrition and pathogenesis. Recent studies on trypanosomal (trans-) sialidases have suggested that catalysis in all sialidases may proceed via a covalent intermediate similar to that of other retaining glycosidases. Here we provide further evidence to support this suggestion by reporting the 0.97A resolution atomic structure of the catalytic domain of the C. perfringens NanI sialidase, and complexes with its substrate sialic acid (N-acetylneuramic acid) also to 0.97A resolution, with a transition-state analogue (2-deoxy-2,3-dehydro-N-acetylneuraminic acid) to 1.5A resolution, and with a covalent intermediate formed using a fluorinated sialic acid analogue to 1.2A resolution. Together, these structures

Alpha toxin, a phospholipase C, is the most important toxin involved in gas gangrene resulting from C. perfringens invasion into traumatic wounds or deoxygenated tissues (1, 15). Since C. perfringens is now being used as an antigen delivery vehicle for an oral vaccine, it is necessary to inactivate the plc gene in this vector for safety reasons. In this report we modified Target-Tron technology for application in C. perfringens. This involved constructing a shuttle plasmid containing a modified L. lactis Ll.LtrB intron and then selecting insertional mutants after introducing the plasmid into C. perfringens.. The retrohoming reaction of the L. lactis Ll.LtrB intron is carried out by a ribonucleoprotein complex of an intron-encoded protein (IEP) and excised intron lariate RNA. The IEP first recognizes a small number of fixed positions in the flanking regions of the DNA target site and facilitates local DNA unwinding, enabling the intron RNA to base pair to a 14- to 16-nucleotide target region. ...

Clostridium perfringens is an anaerobic gram-positive spore-forming bacillus. It is one of the pathogens with larger distribution in the environment; it can be isolated from soil and water samples, which also belongs to the intestinal flora of animals and humans. However, on some occasions it can act as an opportunistic pathogen, causing diseases such as gas gangrene, enterotoxemia in sheep and goats and lamb dysentery, among others. In human beings, it is associated to diseases such as food poisoning, necrotic enterocolitis of the infant and necrotic enteritis or pigbel in Papua-New Guinea tribes.

First described by Klein in 1899, it was noted to be the most prominent bacteria during human decomposition; historically it was described as putrefying flora. Clostridium cadaveris is usually considered non-pathogenic; unlike other species of Clostridium, it does not produce toxins. Clostridium cadaveris is found in soil, water, and is a normal component of the human intestinal tract. The genus Clostridium is large and phylogenetically diverse, comprising over 150 species. Clostrida are extensively found in nature predominantly as benign soil saprophytes. A number of Clostridium species are pathogenic to humans. Members including C.botulinium, C. perfringens, and C.septicum are spore forming and the cause of botulism and gas gangrene respectively. Clostridium cadaveris is closely related phylogenetically to Clostridium fallax and Clostridium intestinale. Infections in ...

Look, its easy to view the above as a bit of political satire, but its actually the way new usages enter a language. Gangrene as a political tag is a perfect extension of the concept of a diseased limb rotting from lack of oxygen to an economy rotting from lack of energy. Gangrene also starts with the word gang, which accurately identifies the leadership of the Gangrene movement as gangsters.. I first tried to move away from the concept of green entirely, when a half year ago I started a Facebook Group called The Golden Economy. But trying to change the language of a debate is an uphill battle so instead of trying to challenge everything associated with the green political movement Ive decided to take on the slightly more modest task of distinguishing between life-affirming green pursuits and life-strangling gangrene policies.. So lets start contrasting Green versus Gangrene.. ...

Gangrene is a localised area of tissue death and is normally the result of a critically insufficient blood supply to part of the body. It can be classified as dry or wet. Dry gangrene does not cause sepsis or cause the patient to die. However, it can result in local tissue death with the tissue eventually being sloughed off. Wet gangrene is usually infected by bacteria, and if left untreated, the patient usually develops sepsis and dies within a few hours or days.

A central challenge for efficient auto-ignition controlled low-temperature gasoline combustion (LTGC) engines has been achieving the combustion phasing needed to reach stable performance over a wide operating regime. The negative valve overlap (NVO) strategy has been explored as a way to improve combustion stability through a combination of charge heating and altered reactivity via a recompression stroke with a pilot fuel injection. The study objective was to analyze the thermal and chemical effects on NVO-period energy recovery. The analysis leveraged experimental gas sampling results obtained from a single-cylinder LTGC engine along with cylinder pressure measurements and custom data reduction methods used to estimate period thermodynamic properties. The engine was fueled by either iso-octane or ethanol, and operated under sweeps of NVO-period oxygen concentration, injection timing, and fueling rate. Gas sampling at the end of the NVO period was performed via a custom dump-valve apparatus, ...
