Clostridium tetani: The cause of TETANUS in humans and domestic animals. It is a common inhabitant of human and horse intestines as well as soil. Two components make up its potent exotoxin activity, a neurotoxin and a hemolytic toxin.Tetanus Toxin: Protein synthesized by CLOSTRIDIUM TETANI as a single chain of ~150 kDa with 35% sequence identity to BOTULINUM TOXIN that is cleaved to a light and a heavy chain that are linked by a single disulfide bond. Tetanolysin is the hemolytic and tetanospasmin is the neurotoxic principle. The toxin causes disruption of the inhibitory mechanisms of the CNS, thus permitting uncontrolled nervous activity, leading to fatal CONVULSIONS.Tetanus: A disease caused by tetanospasmin, a powerful protein toxin produced by CLOSTRIDIUM TETANI. Tetanus usually occurs after an acute injury, such as a puncture wound or laceration. Generalized tetanus, the most common form, is characterized by tetanic muscular contractions and hyperreflexia. Localized tetanus presents itself as a mild condition with manifestations restricted to muscles near the wound. It may progress to the generalized form.Tetanus Antitoxin: An antitoxin used for the treatment of TETANUS.Clostridium: A genus of motile or nonmotile gram-positive bacteria of the family Clostridiaceae. Many species have been identified with some being pathogenic. They occur in water, soil, and in the intestinal tract of humans and lower animals.Clostridium botulinum: A species of anaerobic, gram-positive, rod-shaped bacteria in the family Clostridiaceae that produces proteins with characteristic neurotoxicity. It is the etiologic agent of BOTULISM in humans, wild fowl, HORSES; and CATTLE. Seven subtypes (sometimes called antigenic types, or strains) exist, each producing a different botulinum toxin (BOTULINUM TOXINS). The organism and its spores are widely distributed in nature.Clostridium difficile: A common inhabitant of the colon flora in human infants and sometimes in adults. It produces a toxin that causes pseudomembranous enterocolitis (ENTEROCOLITIS, PSEUDOMEMBRANOUS) in patients receiving antibiotic therapy.Foot Injuries: General or unspecified injuries involving the foot.Encyclopedias as Topic: Works containing information articles on subjects in every field of knowledge, usually arranged in alphabetical order, or a similar work limited to a special field or subject.

Tetanus toxin L chain is processed by major histocompatibility complex class I and class II pathways and recognized by CD8+ or CD4+ T lymphocytes. (1/95)

Tetanus toxin (TeNT) is a heterodimeric protein antigen, whose light chain (L) is translocated in the cytosol of neuronal target cells specifically to cleave its substrates, vesicle-associated membrane protein-2 (VAMP-2, or synaptobrevin) or cellubrevin. We report that the L chain behaves as a nominal antigen recognized by specific T-cell clones upon either class I- or II-restricted presentation. Three types of responses are observed: (i) a TeNT- and L-specific CD8+ T-cell response, that can be inhibited in a dose-dependent manner by the proteasome inhibitor clasto-Lactacystin beta-lactone; (ii) a CD4+ T-cell response specific for L but not TeNT, with recognition of a determinant processed in a chloroquine-sensitive and brefeldin A-resistant compartment; (iii) a CD4+ T-cell response against both L and TeNT, with processing in a brefeldin A-sensitive compartment. The L chain processing was investigated in U937 cells by internalization and localization of L chain by separation of the cell content by differential centrifugation experiments. After incubation with TeNT or L chain in the presence of H chain, the L chain was predominantly distributed in the cytosolic fraction, whereas incubation with L alone led to localization in a lysosome/membrane fraction. The distribution of the TeNT L chain in both cytosolic and endocytic compartments of the antigen-presenting cell accounted for its processing by both class I and class II pathways. Furthermore, an epitope overlapping with the zinc-binding region was recognized by CD4+ and CD8+ T cells.  (+info)

A defined medium for the growth of Clostridium tetani and other anaerobes of clinical interest. (2/95)

The growth of six strains of Clostridium tetani was assessed in a chemically supplemented commercially available defined medium. All strains grew reliably even after 12 serial passages, and two strains produced demonstrable toxic activity after passage. Consistent growth of the test strains could also be obtained on a solid version of this medium ("CA109-S" medium), and the strains could be serially passaged on this medium. Preliminary evidence is presented that the medium supports the surface growth of some other test anaerobes. Such a defined solid medium might prove of value in further studies on the surface growth of C. tetani and of other anaerobes of clinical interest.  (+info)

Isolation and purification of two antigenically active, "complimentary" polypeptide fragments of tetanus neurotoxin. (3/95)

Tetanus neurotoxin (molecular weight approximately 160,000) was purified from bacterial extracts (intracellular toxin) and mildly trypsinized and from culture filtrates (extracellular toxin). Both purified preparations could be dissociated reversibly into two polypeptide chains, with molecular weights of 53,000 (fragment alpha) and 107,000 (fragment beta), by treatment with 100 mM dithiothreitol (DTT) and 4 M urea with concomitant loss of toxicity. Upon removal of DDT and urea from the dissociated toxin preparation by dialysis, these fragments reassociated, forming the whole toxin. The two fragments were isolated and purified from the dissociated toxin by gel filtration on an Ultrogel AcA 44 column equilibrated with buffer containing 2 M urea and 1 mM DTT. The preparation of fragment alpha was nontoxic whereas that of fragment beta was slightly toxic. Immunodiffusion analyses, using horse antitoxin, showed that the antigenicities of fragment alpha and fragment beta were distinct from each other but were partially identical with that of undissociated toxin. The abilities of these fragments to precipitate antitoxin were lost on heating at 60 C for 5 min. The molecular substructure of tetanus neurotoxin is discussed on the basis of these findings.  (+info)

Safety and immunogenicity of a new equine tetanus immunoglobulin associated with tetanus-diphtheria vaccine. (4/95)

In a single-center double-blind, randomized trial in West Africa, we evaluated the safety and immunogenicity of a new pasteurized, pepsin-digested equine tetanus immunoglobulin (heat-treated equine tetanus immunoglobulin [HT-ETIG]) in the post-exposure prophylaxis of tetanus compared with the reference product, equine tetanus immunoglobulin (ETIG). A total of 134 adults presenting to Garoua Hospital, Cameroon with a tetanus-prone wound were randomized to receive a 3,000 international units (IU) intramuscular injection (deltoid) of either HT-ETIG or ETIG, simultaneously with a tetanus-diphtheria vaccine. No serious adverse reactions were reported. The incidences of local and systemic reactions were similar in the two groups. Repeated measures of equine tetanus-antibody levels measured from Day 0 to Day 28 showed that titers were significantly higher in the HT-ETIG group (P = 0.017). At Day 7, a higher percentage of subjects in the HT-ETIG group had equine antibody levels > or = 0.1 IU/ml (80.4% versus 37.9%; P < 0.0001). No cases of tetanus occurred during the follow-up, attesting to the efficacy of the combined prophylactic treatment.  (+info)

Protection against tetanus by needle-free inoculation of adenovirus-vectored nasal and epicutaneous vaccines. (5/95)

The effectiveness of vaccination programs would be enhanced greatly through the availability of vaccines that can be administered simply and, preferably, painlessly without the need for timed booster injections. Tetanus is a prime example of a disease that is readily preventable by vaccination but remains a major threat to public health due to the problems associated with administration of the present vaccine. Here we show that a protective immune response against live Clostridium tetani infection in mice can be elicited by an adenovirus vector encoding the tetanus toxin C fragment when administered as a nasal or epicutaneous vaccine. The results suggest that these vaccination modalities would be effective needle-free alternatives. This is the first demonstration that absorption of a small number of vectored vaccines into the skin following topical application of a patch can provide protection against live bacteria in a disease setting.  (+info)

Antibody responses to vaccinations given within the first two years after transplant are similar between autologous peripheral blood stem cell and bone marrow transplant recipients. (6/95)

As a consequence of the significantly larger inoculum of lymphoid cells present in peripheral blood stem cell (PBSC) harvests compared to bone marrow (BM), it is possible that autoPBSCT recipients may have an earlier and*or enhanced response to vaccines. Until data to confirm this become available, the European Blood and Marrow Transplantation Association (EBMT) recommend that all transplant recipients be immunized in the same way regardless of stem cell source. We performed a prospective study comparing serological responses to influenza, pneumococcal polysaccharide and tetanus toxoid vaccines between autoPBSCT with autoBMT recipients. Antibody responses in sibling HLA-matched allogeneic BMT (alloBMT) survivors were also evaluated. All vaccines were administered within the first 2 years after stem cell transplantation. Fifty patients were enrolled. The time of vaccination after transplant was similar between autoPBSCT (mean 11 months for each vaccine) and autoBMT recipients (mean 12 months except 13 months for tetanus toxoid) (P = NS). Serological responses were poor and no significant difference in response to any of the vaccines used was seen between the three transplant cohorts. We provide no evidence that current EBMT guidelines be modified. Large prospective vaccine studies are needed to address the issue more fully.  (+info)

Chronic ulcers and myasis as ports of entry for Clostridium tetani. (7/95)

Evaluating tetanus immune status is not yet the usual clinical practice regarding patients with chronic ulcers or myasis. However, of 858 tetanus patients at Hospital Couto Maia (Salvador, Bahia, Brazil) aged 1 year or above, 2 had pressure ulcers and 17 had chronic ulceration of the lower limbs where these skin lesions were the ports of entry for Clostridium tetani. In these 19 cases, the following predisposing factors were described: venous insufficiency (n=6), sickle cell anemia (n=2), Hansen s disease (n=1), malnutrition (n=1), diabetes mellitus (n=1), trauma (n=1) and unknown factors (n=7). In 6 other cases, in addition to the Hansen s disease patient, the port of entry for tetanus was the site of extraction of Tunga penetrans larvae. In these 25 cases, the majority of patients (68%) were over 40 years old (17/25) and all of these patients stated that they had either not followed a tetanus toxoid vaccination regimen (19/25), or had partially completed such a regimen, or did not give precise information (6/25). Among the same series studied, over half (52%) of the patients died (13/25). We conclude that tetanus prevention must be included in the treatment of chronic skin ulcer patients, vaccination coverage should be increased among older people, and strategies aimed at improving coverage for all age groups must be reviewed.  (+info)

The genome sequence of Clostridium tetani, the causative agent of tetanus disease. (8/95)

Tetanus disease is one of the most dramatic and globally prevalent diseases of humans and vertebrate animals, and has been reported for over 24 centuries. The manifestation of the disease, spastic paralysis, is caused by the second most poisonous substance known, the tetanus toxin, with a human lethal dose of approximately 1 ng/kg. Fortunately, this disease is successfully controlled through immunization with tetanus toxoid; nevertheless, according to the World Health Organization, an estimated 400,000 cases still occur each year, mainly of neonatal tetanus. The causative agent of tetanus disease is Clostridium tetani, an anaerobic spore-forming bacterium, whose natural habitat is soil, dust, and intestinal tracts of various animals. Here we report the complete genome sequence of toxigenic C. tetani E88, a variant of strain Massachusetts. The genome consists of a 2,799,250-bp chromosome encoding 2,372 ORFs. The tetanus toxin and a collagenase are encoded on a 74,082-bp plasmid, containing 61 ORFs. Additional virulence-related factors could be identified, such as an array of surface-layer and adhesion proteins (35 ORFs), some of them unique to C. tetani. Comparative genomics with the genomes of Clostridium perfringens, the causative agent of gas gangrene, and Clostridium acetobutylicum, a nonpathogenic solvent producer, revealed a remarkable capacity of C. tetani: The organism can rely on an extensive sodium ion bioenergetics. Additional candidate genes involved in the establishment and maintenance of a pathogenic lifestyle of C. tetani are presented.  (+info)

Clostridium tetani. Coloured Scanning Electron Micrograph (SEM) of a cluster of the bacteria Clostridium tetani, cause of tetanus (lockjaw). These bacteria are Gram-positive, spore-forming, rod-shaped anaerobic bacilli. Clostridium tetani produce spores which live in soil and in manure, but are also found in the human intestine. If the spores or bacteria enter the body through a wound, tetanus may result. Bacteria multiply producing a nerve toxin which affects the activity of muscles. Stiffness of the jaw (lockjaw), back and facial muscles may occur with painful spasms. DPT vaccination in childhood immunizes against tetanus.

Clostridium tetani, formerly known as bacillus Nicolaier is a gram-positive bacillus spore forming, anaerobic strict, which releases an exotoxin neurotropic
While C. tetani is frequently benign in the soil or in the intestinal tracts of animals, it can sometimes cause the severe disease tetanus. Disease generally begins with spores entering the body through a puncture wound.[7] Once inside a wound, C. tetani spores germinate and grow, releasing the toxins tetanolysin and tetanospasmin as cells lyse.[2] The function of tetanolysin is unclear, although it may help C. tetani to establish infection within a wound.[8][2] Tetanospasmin (also called "tetanus toxin") is one of the most potent toxins known, with an estimated lethal dose of less than 2.5 nanograms per kilogram of body weight, and is responsible for the symptoms of tetanus.[8][2] Tetanospasmin spreads via the lymphatic system and bloodstream throughout the body, where it is taken up into various parts of the nervous system.[8] In the nervous system, tetanospasmin acts by blocking the release of the inhibitory neurotransmitters glycine and gamma-aminobutyric acid at motor nerve endings.[7] This ...
This enzyme is involved in nucleotide metabolism: it produces dUMP, the immediate precursor of thymidine nucleotides and it decreases the intracellular concentration of dUTP so that uracil cannot be incorporated into DNA.
The infection begins when endospores of C. tetani enter an anaerobic wound. Tetanus can also occur in burn victim, in patients receiving intramuscular injections, person obtaining a tattoo, in persons with frostbite, dental infections, penetrating eye injuries and umbilical stump infections. Other risk factors include diabetes, chronic wounds(skin ulcers.gangrene) parental drug abuse and recent surgery .Unvaccinated mother, home delivery, and unhygienic cutting of the umbilical cord increase susceptibility to tetanus. History of neonatal tetanus in a previous child is a risk factor for subsequent neonatal tetanus. Potentially infectious substances applied to the umbilical stump (e.g., animal dung, mud, clarified butter) are risk factors for neonates. Immunity from tetanus decreases with advancing age. Since the bacterium is an obligate anaerobe, an anaerobic environment is needed for the endospores to germinate and the vegetative bacteria to grow. Vegetative bacteria eventually produce ...
Ive had parents often come into the emergency room after their child has taken a tumble asking for a Tetanus vaccine, which is why I felt the need to write a post explaining what Tetanus is and why we need to vaccinate our kids.. WHAT IS TETANUS?. Tetanus is a disease commonly known as lockjaw. It is caused by the bacteria, Clostridium tetani and can be fatal. The toxin from the bacteria affects the nervous system and causes severe painful muscle spasms, which can interfere with the ability to breathe. Currently there is no cure for Tetanus and treatment is mainly symptomatic until the effects of the toxin wear off. Complete recovery can take up to several months.. WHERE IS THE BACTERIA FOUND?. Clostridial spores can be found everywhere. They are found in soil, dust and animal faeces (including humans). Once the spores enter a wound they grow into mature bacteria, which produce the powerful toxin. Clostridium tetani is found worldwide.. WHAT ARE THE SIGNS AND SYMPTOMS OF TETANUS?. Signs and ...

Tetanus is a terrible disease cause by Clostridium tetani bacteria. Horses are particularly sensitive to tetanus when compared with other species. Clostridium tetani bacteria normally gain entry through a wound. These bacteria then produce a toxin which results in a contraction of the musculature. Horses affected will normally appear distressed, with rigid, pricked up ears and protrusion of the 3rd eyelid when the head is lifted. Lockjaw is a term associated with tetanus, whereby the horse is unable to open its mouth, leaving it unable to eat or drink. Fortunately we are able to prevent it through the use of vaccination. The prognosis for any horse with tetanus is very guarded, it is a very distressing disease for horse and owner alike, and for this reason we recommend all horses are vaccinated against tetanus. Initial vaccination requires the administration of 2 injections approximately 4 weeks apart, a further injection 18 months later, and then repeated every other year. ...
Tetanus is a common, fatal disease in sheep and goats caused by a bacterium known as Clostridium tetani. The spores of this bacterium can be found in feces, they produce a powerful toxin in open wounds, and are not affected or destroyed by disinfectants. Most often, tetanus is caused by infection of an open wound. Because sheep undergo several maintenance procedures, such as castration, ear-marking, tail-docking, dehorning and debudding, sheep are highly at risk for contracting tetanus. Dog bites or deep scratches can also be homes for the bacteria. Incubation of Clostridium tetani is between 3 days and 3 weeks. During this time, the bacteria multiply and generate this powerful toxin. This toxin then affects the nerves around the site of injury/wound, travels to the spinal cord and brain, and ultimately causes uncontrollable muscle spasms. Consequently, signs and symptoms of tetanus infection include muscle stiffness and spasms, bloat, panic, uncoordinated walking and movements, and/or the ...

Tetanus neurotoxin (TeNT) secreted by Clostridium tetani is the causative agent of the spastic paralysis distinctive of human tetanus. TeNT is structurally related to the family of botulinum neurotoxins (BoNTs) produced by Clostridium botulinum that cause flaccid paralysis by disabling synaptic exocytosis at peripheral cholinergic neurons. By contrast, TeNT targets the central nervous system (CNS) by hijacking receptors for neurotrophic factors to enter peripheral neurons thereby being sorted into non‐acidifying endosomes, trafficking via retrograde axonal transport organelles, and entering spinal inhibitory interneurons after transcytosis (Fig 1A). In this issue of EMBO Reports, Masuyer et al [1] describe the structural plasticity of individual TeNT domains in the context of the holotoxin in response to environmental pH, a key factor modulating TeNT fate and action. Through the concerted use of X‐ray crystallography, single particle cryo‐EM, and small angle X‐ray scattering (SAXS), the ...

Tetanus is caused by the tetanus bacterium Clostridium tetani.[1] Tetanus is an international health problem, as C. tetani endospores are ubiquitous. Endospores can be introduced into the body through a puncture wound (penetrating trauma). Due to C. tetani being an anaerobic bacterium, it and its endospores thrive in environments that lack oxygen, such as a puncture wound. The disease occurs almost exclusively in persons inadequately immunized.[22] It is more common in hot, damp climates with soil rich in organic matter. Manure-treated soils may contain spores, as they are widely distributed in the intestines and feces of many animals such as horses, sheep, cattle, dogs, cats, rats, guinea pigs, and chickens.[1] In agricultural areas, a significant number of human adults may harbor the organism. The spores can also be found on skin surfaces and in contaminated heroin.[1] Heroin users, particularly those that inject the drug subcutaneously, appear to be at high risk of contracting tetanus.[1] ...
On day 5 postoperatively, the patient developed tonicclonic seizures. There was no previous history of epilepsy. The patient was apyrexial. He had spasms, tenesmus and opisthotonus. The spatula test was positive. Blood investigations showed a neutrophilia of 84.6% with other parameters being normal. The patient was subsequently admitted to the ICU and started on tetanus immunoglobulin, anticonvulsants (phenytoin), metronidazole, penicillin G, as well as supportive measures.. He demised 10 days later in ICU.. Discussion. Tetanus is a devastating disease involving muscle spasm and autonomic instability. It is caused by the exotoxin (tetanospasmin) of Clostridium tetani, which is a Grampositive, anaerobic, spore-forming bacillus. This bacterium needs low oxygen tension for its survival and it is very sensitive to heat.

It strikes young and old alike, often invading the body through innocuous wounds. Tetanus is caused by tetanospasmin and tetanolysin, the deadly toxins of the bacterium Clostridium tetani. The disease is classified as generalised, localised, cephalic, or neonatal tetanus. It is characterised by painful spasms which manifest as lockjaw (trismus), facial contortions (risus sardonicus), trunkal rigidity (opisthotonus), and vocal cord spasms (laryngospasm). The disease is awfully distressing and, when advanced, untreatable. It is a stain on the world that this avoidable disorder continuous to threaten a large number of its inhabitants. Check neurochecklists for more on the pathology, clinical features, and management of tetanus.. ...

Q: I thought there was no tetanus anymore in the United States, so why do I need a tetanus shot?A: Tetanus is not passed from person to person. It is caused by a neurotoxin produced by the bacterium Clostridium tetani, which lives in the gut of many animals and so can exist in soil/dust pretty much anywhere. Therefore, it is not a disease that can be eradicated. Tetanus is one of the diseases that does not give lifelong immunity.Typically C. tetani spores enter the body through a contaminated

Clostridium tetani, the causative agent of tetanus, is ubiquitous in the environment and distributed worldwide. The organism is found in soil and in the intestines of animals and humans. When spores of C. tetani are introduced into the anaerobic or hypoaerobic conditions found in wounds or devitalized tissue, they germinate to vegetative bacilli that elaborate toxin and cause disease. This now infrequent but often fatal disease has been associated with injuries to otherwise healthy persons, particularly during military conflicts. During 1998--2000, the case-fatality ratio for reported tetanus in the United States was 18% (26). Although tetanus is not transmitted from person to person, contamination of wounds with debris might increase the risk for tetanus among persons injured in mass-casualty settings. Proper wound care and debridement play a critical role in tetanus prevention. Serologic tests indicate that immunity to tetanus toxin is not acquired naturally. However, protection against ...
Many people believe that you can get a single dose tetanus-only shot. The only tetanus vaccine available in the U.S. contains both diphtheria toxoid and tetanus toxoid. Following are the ingredients and description of manufacturing for Sanofi Pasteur s DT (Diphtheria/Tetanus) pediatric vaccine taken straight out of the package insert: DESCRIPTION Diphtheria and Tetanus Toxoids Adsorbed USP (For Pediatric Use) (DT), for intramuscular use, is a sterile suspension of alum-precipitated (aluminum potassium sulfate) toxoid in an isotonic sodium chloride solution. The vaccine, after shaking, is a turbid liquid, whitish-gray in color. Corynebacterium diphtheriae cultures are grown in a modified Mueller and Miller medium.1 Clostridium tetani cultures are grown in a peptone-based medium containing bovine extract. The meat used in this medium is US sourced. Both toxins are detoxified with formaldehyde. The detoxified materials are then separately purified by serial ammonium sulfate fractionation and ...

Glycine (symbol Gly or G;[5] /ˈɡlaɪsiːn/)[6] is an amino acid that has a single hydrogen atom as its side chain. It is the simplest amino acid (since carbamic acid is unstable), with the chemical formula NH2‐CH2‐COOH. Glycine is one of the proteinogenic amino acids. It is encoded by all the codons starting with GG (GGU, GGC, GGA, GGG). Glycine is integral to the formation of alpha-helices in secondary protein structure due to its compact form. For the same reason, it is the most abundant amino acid in collagen triple-helices. Glycine is also an inhibitory neurotransmitter - interference with its release within the spinal cord (such as during a Clostridium tetani infection) can cause spastic paralysis due to uninhibited muscle contraction. Glycine is a colorless, sweet-tasting crystalline solid. It is the only achiral proteinogenic amino acid. It can fit into hydrophilic or hydrophobic environments, due to its minimal side chain of only one hydrogen atom. The acyl radical is glycyl. ...
Tetanus, also known as lockjaw, is a serious bacterial infection caused by the bacteria Clostridium tetani. Tetanus causes severe muscle spasms and can be fatal.

Q: Isnt there a rat poison that causes tetanus infection?A: No. The medical condition known as tetanus is due to a neurotoxin produced by Clostridium tetani (as discussed in last weeks column), and that requires infection with this bacterium. However, strychnine (a substance sometimes used in rat poisons) poisoning may have some symptoms similar to tetanus, specifically tetany (involuntary contraction of muscles).Poisons are one method used to control rat populations, and
The author, with blinding flashbacks of treating this disease, witnessed a talk show conversation wherein a young empty headed starlet with the strong certainty that characterizes knowing nothing, espoused naturalism through the avoidance of vaccinations - including tetanus.. Talk about stupid! Try this on, a child bent backward in unremitting muscle anarchy such that buttocks are pressed against the back of the head enfolded within rigid violently shaking thighs as vertebrae audibly break in sequence, one by one. Thats tetanus. Dont worry about the mechanism. This ones preventable. Get the shots. Keep them up to date. Nastier than any tyrannosaurus, the organism that causes tetanus is everywhere. Rarity of this disease merely reflects the populations immunity status.. Clostridium tetani secretes toxins which block GABA (gamma amino butyrate) and glycine in the inhibitory neural circuits. There is also direct muscle damage. A botulism-type mix may also be seen with paralysis. About one week ...
Scientists who use animals or animal tissues in their experiments need to be protected from hazards in the laboratory. For example, a bite from a rat can transmit disease and make a person sick. Most laboratories will be part of an occupational health program that monitors the scientists health.. The occupational health program that monitors my laboratory recently told me that it is time to get my tetanus booster shot. Tetanus is caused by bacteria (Clostridium tetani) found in the soil and in the intestinal tracts of some animals. Most cases of tetanus infection occur when people step on objects, such as rusty nails, that are contaminated by the bacteria. Animal bites can also transmit the bacteria.. Tetanus toxin works in the spinal cord by blocking the activity of inhibitory interneurons. These interneurons are connected to other neurons that make muscles contract. The results of this blockage are the classic signs of tetanus infection: stiff and rigid muscles, especially around the jaws. ...
Historically, tetanus was a feared complication of wound infections. This Clostridium tetani toxin-mediated disease is one of several toxin-mediated diseases resulting from wound infections, along with staphylococcal and streptococcal toxic shock syndrome, wound botulism, and wound diphtheria. Since the advent of routine vaccination after trauma injury and passive immunization for grossly contaminated wounds, tetanus has become uncommon in the United States with an average of 43 cases annually from 1998 to 2000.1 Worldwide it is still a major cause of morbidity and mortality, and remains one of the WHO targeted diseases. Overall, 500,000 to 1 million cases occur worldwide each year, with 213,000 deaths, the majority in children less than 5 years of age. This is mainly due to inadequate vaccination, either because of access to care or neonatal infections before vaccination is ...
The diagnosis is a clinical one, relatively easy to make in areas where tetanus is seen often, but often delayed in the developed world where cases are seen infrequently.31 The differential includes tetany, strychnine poisoning, drug induced dystonic reactions, rabies, and orofacial infection. In neonates the differential diagnosis would also include hypocalcaemia, hypoglycaemia, meningitis and meningoencephalitis, and seizures.. Penicillin remains the standard therapy for tetanus in most parts of the world, although antibiotics for Clostridium tetani probably play a relatively minor part in the specific treatment of the disease. The dose is 100 000-200 000 IU/kg/day intramuscularly or intravenously for 7 to 10 days. Johnson and Walker were the first to report that intravenous administration of penicillin could cause convulsions, and went on to show, in animal models, that penicillin caused myoclonic convulsions when applied directly to the cortex.32 Penicillin became the standard model for ...
We describe a case of a diagnostically difficult stroke mimic, cephalic tetanus.1 Currently there are 12-15 cases of tetanus reported annually in the United Kingdom,2 but worldwide it accounts for one million deaths, 80% being in Africa and South East Asia.3 Tetanus is caused by infection with clostridium tetani.4 5 Cephalic Tetanus is defined as a combination of trismus and paralysis of one or more cranial nerves, most commonly the facial nerve. It is rare, 0.9-3% of all tetanus cases, and has a high mortality of between 15-30% if it progresses to generalised tetanus.1. A 76 year old right handed lady presented to the stroke unit with sudden onset of swallowing difficulty, speech impairment and left sided facial weakness on waking. She had multiple vascular risk factors, however on examination her signs had resolved. Of note she had a sutured right supraorbital laceration sustained a week prior to presentation following a road traffic accident. Computed tomography (CT) showed no acute stroke ...

... is a serious Clostridium tetani bacteria-caused infection; the bacteria are responsible for producing a toxin that affects the nervous system and the brain. The toxin leads to stiffness in the muscles of the jaw, muscles in other areas of the body. This is the forum for discussing anything related to this health condition
According to the Mayo Clinic, when the Clostridium tetani bacteria enters a wound spores release a powerful toxin, called tetanospasmin, which actively impairs your motor neurons, nerves that control your muscles. The most common symptoms of tetanus are spasms and stiffness in your jaw muscles, stiffness of your neck muscles, difficulty swallowing, stiffness of your abdominal muscles, painful body spasms lasting for several minutes, typically triggered by minor occurrences, such as a draft, loud noise, physical touch or light. Some people may also suffer from fever, sweating, elevated blood pressure and rapid heart rate ...

Just a note about tetanus. Spores of the bacterium that cause tetanus, Clostridium tetani, are found in soil, dust, saliva and animal faeces. Because it is everywhere, we are continually being bombarded with these spores. It lives within us and is found on the surface of the body, in the mouth, in the gastro-intestinal tract, in house dust and clothing. This continuous contact with the bacteria, gives us a natural immunity and it is usually only the really sick, immune deficient or weakened person who will succumb to it.. Tetanus deaths have been declining steadily over the 20th century with death rates recorded as just 3.5 per 1 million people in 1947 down to 1 death in 50 million in 2007. I think it is a complete waste of money, but the pharmaceutical industry would disagree. They have raked in billions in profits with this vaccine.. ...

By injuries with instruments contaminated with the blood of patients (danger of Hepatitis B or AIDS), or by contaminations of a wound with anthrax, rabies, Pseudomonas mallei, Tetanus (Clostridium tetani) or Clostridium perfringens or other extremely dangerous microbes the contaminating agents have to be killed immediately in the wound. Therefore in these cases the wound itself should be treated directly with tincture of iodine as far as possible. Afterwards a hospital has to be contacted directly and immediately. After any injury, the injured limb has to be immobilized for 24 hours. ...
Soon after starting planning my volunteer trip to Carriacou I was given advice about vaccinations I would require. These were basically for rabies and tetanus. As I was tested and proven that I already had enough anti-bodies against tetanus (Clostridium tetani) all I had to do was to get my rabies shots. Great. Cashed out over £110 for this and thought this was it.. Then later I heard about this Chikungunya virus that was causing issues round the world but it was also prevalent in the Caribbean. Turns out this virus causes a quite nasty disease. OK, not exactly ebola grade badness but can still be lethal in extreme cases and can also cause severe joint pain that can linger for months and even a few years. And, you guessed it, absolutely no vaccine for it.. Want to know more? optimistic version and slightly less cheerful version. ...

Tetanus occurs when a very powerful toxin from a bacteria called Clostridium tetani climbs the nerves into the spinal cord. The nerve cells dont communicate well when this happens and they begin sending too many signals to the muscles. The muscles go into spasm. This is what caused the Haitian babys jaw to lock and his hands to clench. His arched back is due to muscle contraction and is very painful. When contraction of the tracheal and pharyngeal muscles occurs, periods of apnea can occur, and the baby cannot breathe. Seizures and swings in blood pressure are common also ...
