Botulinum Antitoxin: Antiserum given therapeutically in BOTULISM.Botulism: A disease caused by potent protein NEUROTOXINS produced by CLOSTRIDIUM BOTULINUM which interfere with the presynaptic release of ACETYLCHOLINE at the NEUROMUSCULAR JUNCTION. Clinical features include abdominal pain, vomiting, acute PARALYSIS (including respiratory paralysis), blurred vision, and DIPLOPIA. Botulism may be classified into several subtypes (e.g., food-borne, infant, wound, and others). (From Adams et al., Principles of Neurology, 6th ed, p1208)Botulinum Toxins: Toxic proteins produced from the species CLOSTRIDIUM BOTULINUM. The toxins are synthesized as a single peptide chain which is processed into a mature protein consisting of a heavy chain and light chain joined via a disulfide bond. The botulinum toxin light chain is a zinc-dependent protease which is released from the heavy chain upon ENDOCYTOSIS into PRESYNAPTIC NERVE ENDINGS. Once inside the cell the botulinum toxin light chain cleaves specific SNARE proteins which are essential for secretion of ACETYLCHOLINE by SYNAPTIC VESICLES. This inhibition of acetylcholine release results in muscular PARALYSIS.Botulinum Toxins, Type A: A serotype of botulinum toxins that has specificity for cleavage of SYNAPTOSOMAL-ASSOCIATED PROTEIN 25.Antitoxins: Antisera from immunized animals that is purified and used as a passive immunizing agent against specific BACTERIAL TOXINS.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.Drugs, Investigational: Drugs which have received FDA approval for human testing but have yet to be approved for commercial marketing. This includes drugs used for treatment while they still are undergoing clinical trials (Treatment IND). The main heading includes drugs under investigation in foreign countries.Neuromuscular Agents: Drugs used for their actions on skeletal muscle. Included are agents that act directly on skeletal muscle, those that alter neuromuscular transmission (NEUROMUSCULAR BLOCKING AGENTS), and drugs that act centrally as skeletal muscle relaxants (MUSCLE RELAXANTS, CENTRAL). Drugs used in the treatment of movement disorders are ANTI-DYSKINESIA AGENTS.Anti-Dyskinesia Agents: Drugs used in the treatment of movement disorders. Most of these act centrally on dopaminergic or cholinergic systems. Among the most important clinically are those used for the treatment of Parkinson disease (ANTIPARKINSON AGENTS) and those for the tardive dyskinesias.Tetanus Antitoxin: An antitoxin used for the treatment of TETANUS.Diphtheria Antitoxin: An antitoxin produced against the toxin of CORYNEBACTERIUM DIPHTHERIAE that is used for the treatment of DIPHTHERIA.Antibodies: Immunoglobulin molecules having a specific amino acid sequence by virtue of which they interact only with the ANTIGEN (or a very similar shape) that induced their synthesis in cells of the lymphoid series (especially PLASMA CELLS).Blepharospasm: Excessive winking; tonic or clonic spasm of the orbicularis oculi muscle.Spasm: An involuntary contraction of a muscle or group of muscles. Spasms may involve SKELETAL MUSCLE or SMOOTH MUSCLE.Injections, Intramuscular: Forceful administration into a muscle of liquid medication, nutrient, or other fluid through a hollow needle piercing the muscle and any tissue covering it.Muscle Spasticity: A form of muscle hypertonia associated with upper MOTOR NEURON DISEASE. Resistance to passive stretch of a spastic muscle results in minimal initial resistance (a "free interval") followed by an incremental increase in muscle tone. Tone increases in proportion to the velocity of stretch. Spasticity is usually accompanied by HYPERREFLEXIA and variable degrees of MUSCLE WEAKNESS. (From Adams et al., Principles of Neurology, 6th ed, p54)Torticollis: A symptom, not a disease, of a twisted neck. In most instances, the head is tipped toward one side and the chin rotated toward the other. The involuntary muscle contractions in the neck region of patients with torticollis can be due to congenital defects, trauma, inflammation, tumors, and neurological or other factors.Clostridium botulinum type A: Subtype of CLOSTRIDIUM BOTULINUM that produces BOTULINUM TOXINS, TYPE A which is neurotoxic to humans and animals.Clostridium botulinum type E: Subtype of CLOSTRIDIUM BOTULINUM that produces botulinum toxin type E which is neurotoxic to humans and animals.Toxoids: Preparations of pathogenic organisms or their derivatives made nontoxic and intended for active immunologic prophylaxis. They include deactivated toxins. Anatoxin toxoids are distinct from anatoxins that are TROPANES found in CYANOBACTERIA.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.Toxins, Biological: Specific, characterizable, poisonous chemicals, often PROTEINS, with specific biological properties, including immunogenicity, produced by microbes, higher plants (PLANTS, TOXIC), or ANIMALS.Antibodies, Bacterial: Immunoglobulins produced in a response to BACTERIAL ANTIGENS.Antibody Specificity: The property of antibodies which enables them to react with some ANTIGENIC DETERMINANTS and not with others. Specificity is dependent on chemical composition, physical forces, and molecular structure at the binding site.Sialorrhea: Increased salivary flow.Contracture: Prolonged shortening of the muscle or other soft tissue around a joint, preventing movement of the joint.Tendons: Fibrous bands or cords of CONNECTIVE TISSUE at the ends of SKELETAL MUSCLE FIBERS that serve to attach the MUSCLES to bones and other structures.New JerseyHip Contracture: Permanent fixation of the hip in primary positions, with limited passive or active motion at the hip joint. Locomotion is difficult and pain is sometimes present when the hip is in motion. It may be caused by trauma, infection, or poliomyelitis. (From Current Medical Information & Technology, 5th ed)Tendon Injuries: Injuries to the fibrous cords of connective tissue which attach muscles to bones or other structures.Achilles Tendon: A fibrous cord that connects the muscles in the back of the calf to the HEEL BONE.Spores, Bacterial: Heat and stain resistant, metabolically inactive bodies formed within the vegetative cells of bacteria of the genera Bacillus and Clostridium.Eyebrows: Curved rows of HAIR located on the upper edges of the eye sockets.Diplopia: A visual symptom in which a single object is perceived by the visual cortex as two objects rather than one. Disorders associated with this condition include REFRACTIVE ERRORS; STRABISMUS; OCULOMOTOR NERVE DISEASES; TROCHLEAR NERVE DISEASES; ABDUCENS NERVE DISEASES; and diseases of the BRAIN STEM and OCCIPITAL LOBE.Eye Movements: Voluntary or reflex-controlled movements of the eye.Heart Murmurs: Heart sounds caused by vibrations resulting from the flow of blood through the heart. Heart murmurs can be examined by HEART AUSCULTATION, and analyzed by their intensity (6 grades), duration, timing (systolic, diastolic, or continuous), location, transmission, and quality (musical, vibratory, blowing, etc).Heroin Dependence: Strong dependence, both physiological and emotional, upon heroin.Civil Disorders: Deliberate and planned acts of unlawful behavior engaged in by aggrieved segments of the population in seeking social change.Abducens Nerve: The 6th cranial nerve which originates in the ABDUCENS NUCLEUS of the PONS and sends motor fibers to the lateral rectus muscles of the EYE. Damage to the nerve or its nucleus disrupts horizontal eye movement control.Endopeptidases: A subclass of PEPTIDE HYDROLASES that catalyze the internal cleavage of PEPTIDES or PROTEINS.Neprilysin: Enzyme that is a major constituent of kidney brush-border membranes and is also present to a lesser degree in the brain and other tissues. It preferentially catalyzes cleavage at the amino group of hydrophobic residues of the B-chain of insulin as well as opioid peptides and other biologically active peptides. The enzyme is inhibited primarily by EDTA, phosphoramidon, and thiorphan and is reactivated by zinc. Neprilysin is identical to common acute lymphoblastic leukemia antigen (CALLA Antigen), an important marker in the diagnosis of human acute lymphocytic leukemia. There is no relationship with CALLA PLANT.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.Poison Control Centers: Facilities which provide information concerning poisons and treatment of poisoning in emergencies.Capnography: Continuous recording of the carbon dioxide content of expired air.Hospitals, County: Hospitals controlled by the county government.Oximetry: The determination of oxygen-hemoglobin saturation of blood either by withdrawing a sample and passing it through a classical photoelectric oximeter or by electrodes attached to some translucent part of the body like finger, earlobe, or skin fold. It includes non-invasive oxygen monitoring by pulse oximetry.Charcoal: An amorphous form of carbon prepared from the incomplete combustion of animal or vegetable matter, e.g., wood. The activated form of charcoal is used in the treatment of poisoning. (Grant & Hackh's Chemical Dictionary, 5th ed)Poisoning: A condition or physical state produced by the ingestion, injection, inhalation of or exposure to a deleterious agent.Ciguatoxins: Polycyclic ethers produced by Gambierdiscus (DINOFLAGELLATES) from gambiertoxins, which are ingested by fish which in turn may be ingested by humans who are susceptible to the CIGUATERA POISONING.Oxocins: Compounds based on an 8-membered heterocyclic ring including an oxygen. They can be considered medium ring ethers.Marine Toxins: Toxic or poisonous substances elaborated by marine flora or fauna. They include also specific, characterized poisons or toxins for which there is no more specific heading, like those from poisonous FISHES.Dictionaries, MedicalDictionaries as Topic: Lists of words, usually in alphabetical order, giving information about form, pronunciation, etymology, grammar, and meaning.Exotoxins: Toxins produced, especially by bacterial or fungal cells, and released into the culture medium or environment.Dictionaries, Chemical

Two other forms of botulism also have occurred. Adult intestinal botulism is very rare and occurs among adults by the same route as infant botulism. Iatrogenic botulism is also very rare and can occur as a complication from injecting botulism toxin for cosmetic or medical purposes.. Who gets botulism?. Anyone can get botulism with about 200 cases reported in the United States each year. Most cases involve infant botulism which occurs in babies younger than 12 months old. Infant botulism has been associated with honey, a natural product that can contain botulism spores. Foodborne botulism can occur after eating home-canned, preserved or fermented foods that are contaminated with toxin. Foods with low acid content (e.g., asparagus, green beans, beets, corn, and potatoes) are the most common sources of home-canning related botulism. Wound botulism can occur more often in people who inject drugs or who have open wounds that are exposed to soil or gravel. Iatrogenic botulism is rare but can occur ...

Botulism in the United States: A Clinical and Epidemiologic Review | Annals of Internal Medicine | American College of...
Botulism is caused by a neurotoxin produced from the anaerobic, spore-forming bacterium Clostridium botulinum. Botulism in humans is usually caused by toxin types A, B, and E. Since 1973, a median of 24 cases of foodborne botulism, 3 cases of wound botulism, and 71 cases of infant botulism have been reported annually to the Centers for Disease Control and Prevention (CDC). New vehicles for transmission have emerged in recent decades, and wound botulism associated with black tar heroin has increased dramatically since 1994. Recently, the potential terrorist use of botulinum toxin has become an important concern.. Botulism is characterized by symmetric, descending, flaccid paralysis of motor and autonomic nerves, usually beginning with the cranial nerves.Blurred vision, dysphagia, and dysarthria are common initial complaints. The diagnosis of botulism is based on compatible clinical findings; history of exposure to suspect foods; and ...
There are three main types of botulism, categorized by the way the disease is acquired. Food-borne botulism is caused by eating food contaminated with botulinum toxin. This typically occurs when a stored food item contains Clostridium botulinum spores which begin to grow and produce the toxin within the food item, if environmental conditions are favorable.. Wound botulism occurs when the Clostridium botulinum bacteria infects a wound and then produces the toxin.. Infant botulism occurs when an infant consumes the spores of the botulinum bacteria which are commonly found in the environment. Once the bacteria enter an infants immature intestines, the spores can grow produce and release the toxins.. Adult intestinal botulism is the rarest form of botulism. Like infant botulism, it is caused when Clostridium botulinum spores are ...

Infant botulism and botulism immune globulin in the UK: a case series of four infants | Archives of Disease in Childhood
A 6-month-old infant was admitted to the intensive care unit of our centre with a 2-day history of poor feeding, decreased movement of all limbs and respiratory distress. The patient was hypotonic and cold peripherally with a metabolic acidosis. Treatment for presumed sepsis was commenced. On day 4 of illness the child became unconscious and bradycardic, necessitating ventilation.. Cranial MRI was normal. Electromyography (EMG) was suggestive of Guillian-Barre syndrome but there was no improvement despite intravenous immunoglobulin therapy. Infantile botulism was queried, and a faecal sample sent for analysis to the regional Health Protection Laboratory confirmed the presence of toxin A producing Clostridium botulinum on PCR. Botulism immune globulin (BabyBIG) was given on day 16 of the illness. Improvement was notable but still slow, requiring continued ventilation for 6 weeks through a tracheostomy ...
Although the worldwide incidence of infant botulism is rare, the majority of cases are diagnosed in the United States. An infant can acquire botulism by ingesting Clostridium botulinum spores, which are found in soil or honey products. The spores germinate into bacteria that colonize the bowel and synthesize toxin. As the toxin is absorbed, it irreversibly binds to acetylcholine receptors on motor nerve terminals at neuromuscular junctions. The infant with botulism becomes progressively weak, hypotonic and hyporeflexic, showing bulbar and spinal nerve abnormalities. Presenting symptoms include constipation, lethargy, a weak cry, poor feeding and dehydration. A high index of suspicion is important for the diagnosis and prompt treatment of infant botulism, because this disease can quickly progress to respiratory failure. Diagnosis is confirmed by isolating the organism or toxin in the stool and finding a classic electromyogram pattern. Treatment consists of nutritional and ...
For clinical consultation for a patient with suspected infant botulism, the patients physician should contact the Infant Botulism Treatment and Prevention Program (IBTPP) on-call physician at (510) 231-7600 (24/7/365).

Foodborne botulism, a potentially lethal neuroparalytic disease, is caused by ingesting preformed Clostridium botulinum neurotoxin. We reviewed surveillance data and reports from 1990 to 2000. Of 263 cases from 160 foodborne botulism events (episode of one or more related cases) in the United States, 103 (39%) cases and 58 events occurred in Alaska. Patients median age was 48 years; 154 (59%) were female; the case-fatality rate was 4%. The median number of cases per event was 1 (range 1-17). Toxin type A caused 51% of all cases; toxin type E caused 90% of Alaska cases. A particular food was implicated in 126 (79%) events. In the lower 49 states, a noncommercial food item was implicated in 70 (91%) events, most commonly, home-canned vegetables (44%). Two restaurant-associated outbreaks affected 25 persons. All Alaska cases were attributable to traditional Alaska Native foods. Botulism prevention efforts should be focused on those who preserve food at home, Alaska Natives, and ...

Barbiturate ingestion in three adult captive tigers (Panthera tigris) and concomitant fatal botulism of one
WILLIAMS, J H et al. Barbiturate ingestion in three adult captive tigers (Panthera tigris) and concomitant fatal botulism of one. J. S. Afr. Vet. Assoc. [online]. 2011, vol.82, n.4, pp.244-249. ISSN 2224-9435.. Zoo animals, including tigers, have been reported to suffer from barbiturate intoxication, with pentabarbitone being most commonly recorded. Clinical signs range from mild ataxia to general anaesthesia with recovery over hours to days with several factors affecting hepatic barbiturate metabolism and tissue partitioning. Botulism is an often fatal intoxication in man, animals, birds and certain fish. The occurrence in carnivores is uncommon to rare, with only 2 reports found of botulism in felids. This report relates to 3 adult captive cohabiting tigers that simultaneously developed signs of abdominal discomfort, progressive ataxia, recumbency and comatose sleep resembling stage 2 anaesthesia, alternating with periods of distracted wakefulness and ataxic movements. These signs occurred 4 ...
Acidic food stuffs like tomatoes have traditionally been thought of as safe as far as the risk of botulism was concerned. However, an outbreak of six cases, one of whom died, in Azerbaijan, which has subsequently been linked to home made pickled tomatoes, has brought that conventional wisdom into question. More of this outbreak can be read on the Azer News article.. Botulism results from the presence of the botulinum toxin, which is a neurotoxin produced by the bacterium Clostridium botulinum. Optimal storage conditions, clean and hygienic preparation and proper pH and salting is known to avoid the development of this bacterial toxin in pickled foods. Using pressure techniques to make pickles out of food matter with low acid content guards against the development of this toxin and using boiling or other conventional techniques maybe dangerous.. ...
Centre for Food Safety - Food Safety Topics - Formula Products Contaminated with Clostridium Botulinum
Formula Products Contaminated with Clostridium Botulinum - FAQ What is Clostridium botulinum? C. botulinum is an anaerobic, gram-positive, spore-forming rod that commonly found in the soil. Although the toxin is destroyed by boiling for 10 minutes or longer; inactivation of spores requires much higher temperature. What is the cause of botulism? Foodborne botulism results from ingestion of preformed toxin present in contaminated foods. Since C. botulinum can only grow in the absence of oxygen, foodborne botulism occurs in products with low oxygen content (e.g. in airtight packaging) as well as with right combination of storage and preservative parameters. The bacterium will grow and produce toxin in these products which are then eaten without sufficient heating or post-production cooking to inactivate the toxin. This is the case in lightly preserved foods such as fermented, ...
The patient was treated with mechanical ventilation and trivalent (A,B,E) equine botulinum antitoxin. Type A toxin was detected in the beans and so was presumably responsible for the symptoms. He made a slow recovery over the next three months. Botulism in the arctic For many years, epidemics of illness have been described in which ﬁsh or meat products are responsible. This is relatively common in the Arctic, where over 200 outbreaks have been reported since the early 1900s, with an overall fatality rate of about 20%. Recently, hepatitis B virus sequences have been found to be integrated into the liver cell genome in some, but not all, patients with chronic hepatitis or primary hepatocellular carcinoma. This evidence has identiﬁed hepatitis B virus as a major etiological factor for primary hepatocellular carcinoma in certain populations, particularly in Taiwan and the Peoples Republic of China. Some epidemiological studies have suggested that aﬂatoxin poses ...
On July 7 and July 11, 2007, public health officials in Texas and Indiana, respectively, reported to CDC four suspected cases of foodborne botulism, two in each state. Investigations conducted by state and local health departments revealed that all four patients had eaten brands of Castleberrys hot dog chili sauce before illness began. Botulinum toxin type A was detected in the serum of one Indiana patient and in a leftover chili mixture obtained from his home. CDC informed the Food and Drug Administration (FDA) of the apparent link between illness and consumption of the chili sauce. On July 18, FDA issued a consumer advisory, and the manufacturer, Castleberrys Food Company (Augusta, Georgia), subsequently recalled the implicated brand and several other products produced in the same set of retorts (commercial-scale pressure cookers for processing canned foods) at the same canning facility. Examination of the canning facility in Georgia during the outbreak investigation had ...

The recall was later expanded to include 80 types of sauces, beans, stew, chili, hash and pet ...
The management of patients suspected of having botulism consists of both supportive measures and antitoxin administration. Management is also complicated by the absence of a timely diagnostic biological marker to confirm the diagnosis and the time sensitive nature of treatment implementation to prevent further progression of illness.. In general, patients should be admitted to an appropriate area of the hospital for continuous monitoring of respiratory and neurological function. There is a risk of progressive muscle weakness and subsequent respiratory failure. Objective measures such as negative inspiratory force, pulse oximetry, and end-tidal capnography are often used to determine need for intubation and ventilator support.. Activated charcoal is generally administered to patients, if no contraindications exist. In vitro studies show that it absorbs serotype toxin A and it is suggested even after a substantial time delay as the bacteria and spores may still be present in the ...

In June 2018, the New York City Department of Health and Mental Hygiene investigated an outbreak of botulism among three related, adult women, which was traced to ingestion of home-canned peas. Botulinum antitoxin was administered and all three patients survived but required prolonged intensive care and rehabilitation.
The chaetoglobins are a structurally unique class of azaphilone alkaloid dimers with reported anticancer activity. They are also a potential platform for the development of antibacterial and botulinum antitoxin. Notably, this class of compounds has not been synthesized to date. Chaetoglobin A (1) and B (2) were originally isolated from the endophytic fungus Chaetomium globosum.1 Chaetoglobin A has been shown to be potentially active against human colon and breast cancer. However, the bioactivity of chaetoglobin B has not been studied due lack of material, suggesting the need of further research. The main goal of this project is the design and optimization of a synthetic route for chaetoglobin natural products. Achiral phenol coupling has been studied for many years; however, the regioselective methods reported to date are substrate-dependent and limited in scope. - Previously, we developed a regio- and enantioselective method for oxidative phenol coupling ...

A newly published research study by scientists at the UK Institute of Food Research (IFR) has identified part of the mechanism by which the resistant endospores of the dangerous foodborne pathogen Clostridium botulinum (the cause of botulism) are able to germinate.. It is known that spore germination is initiated when certain small molecules (germinants) are recognised by a specific germinant receptors (GR) located in the inner membrane of the spore. The IFR researchers were able to identify two active GRs in the spores of Cl. botulinum, which respond to amino acid germinants and act in synergy, but are unable to function alone. Other GRs form a complex that seems to play a role in controlling the speed of germination.. The authors of the study say that understanding the germination mechanism of Cl. botulinum spores is essential if new control measures to prevent germination and subsequent toxin production ...

The Centers for Disease Control and Prevention estimate that 48 million people get sick from foodborne illnesses every year. Thats 1 for every 6 people in the United States. Another 128,000 are hospitalized and 3,000 die annually from foodborne illnesses.. However, of the 48 million people who get sick, the CDC says the cause of the majority of the illnesses is "unspecified agents." A whopping 39.9 million are "due to agents not yet described, unrecognized foodborne agents, and noninfectious agents.". With foodborne illnesses in the news constantly from the Chipotle Restaurant chain to the local farmers, its worth asking about food safety. Its a reasonable assumption that the food that comes from channels such as chain restaurants and grocery stores is safe to eat.. The challenge becomes that many people either purposefully or (in the process of cooking) accidentally remove dangerous bacteria in their food. "Much of the food safety burden falls on the consumer when it comes to meat, poultry, ...
Botulism Toxin Injection as a Treatment for Arthritis of the Basal Thumb Joint - Tabular View - ClinicalTrials.gov
Purpose: Basal joint arthritis, or carpometacarpal (CMC) osteoarthritis, of the thumb is very common, particularly in the elderly. Morbidities include pain, decreased range of motion, and decreased strength. Nonsurgical treatments for CMC arthritis include oral analgesics, splinting, and steroid injection. In multiple recent trials, botulinum toxin A (BTX-A) injection has been shown to be an efficacious nonsurgical option for osteoarthritis of large joints, including those that have failed steroid injections. To our knowledge, the efficacy of BTX-A injection in thumb CMC arthritis has not been examined.. Methods: Patients with a clinical and radiographic diagnosis of basal joint arthritis who are appropriate and willing candidates for injection therapy will be selected. The primary symptom indicating need for injection would be pain not controlled with more conservative measures (e.g. nonsteroidal anti-inflammatory drugs (NSAIDs), splinting, physical therapy, etc.) Weakness ...
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 ...

Patente US7507419 - Topically applied Clostridium botulinum toxin compositions and treatment methods - Google Patentes
Hyperactive glandular conditions are treated using topically formulated botulinum toxin compositions. In the preferred embodiment of the invention, topical botulinum preparations are applied directly to the skin by a patient as needed to suppress his or her hyperhidrosis, bromhidrosis, chromhidrosis, nevus sudoriferous, acne, seborrhiec dermatitis or other glandular condition. In other embodiments, topical botulinum toxins are applied with the aid of mechanical, electrical, and/or chemical transdermal delivery enhancers.
However, foods which are high in refined sugar, trans-fatty acid (milk products) oxidized fatty acids (fried oils) and synthetically hydrogenated vegetable oil contents may not cause acne but are definitely not very good for your health, and so an excess of these foods should be avoided. You can be infected with intestinal toxemia if your diet is low on fiber and essential vitamins and high on these contents. The result of glut of toxins may show on your skin ...
Journal of Pediatric Ophthalmology and Strabismus | Infant botulism is an exceedingly rare disease. Because confirmatory laboratory testing is not available for several days after time of presentation, infant botulism remains a clinical diagnosis. The authors demonstrate how raised intraocular pressure may provide an additional clinical clue to making the diagnosis.
Bacterial toxin-antitoxin loci consist of two genes: one encodes a potentially toxic protein, and the second, an antitoxin to repress its function or expression. The antitoxin can either be an RNA or a protein. For type I and type III loci, the antitoxins are RNAs; however, they have very different modes of action. Type I antitoxins repress toxin protein expression through interacting with the toxin mRNA, thereby targeting the mRNA for degradation or preventing its translation or both; type III antitoxins directly bind to the toxin protein, sequestering it. Along with these two very different modes of action for the antitoxin, there are differences in the functions of the toxin proteins and the mobility of these loci between species. Within this review, we discuss the major differences as to how the RNAs repress toxin activity, the potential consequences for utilizing different regulatory ...
Three outbreaks of botulism type E occurring in waterbirds on Lake Michigan since autumn 1976 are discussed. Natural ingestion of food containing type E toxin by Ring-billed Gulls (Larus delawarensis) and the presence of type E toxin in the blood from moribund gulls were demonstrated. Concurrent presence of type C and type E botulinal toxins was found in a die-off of Common Loons (Gavia immer). In combination with previous reported outbreaks, these incidents suggest that this disease is geographically widespread in Lake Michigan, and that environmental conditions conducive to type E botulinal toxin production and consumption occur in both summer and autumn....
Recombination and insertion events involving the botulinum neurotoxin complex genes in Clostridium botulinum types A, B, E and...
Clostridium botulinum is a taxonomic designation for at least four diverse species that are defined by the expression of one (monovalent) or two (bivalent) of seven different C. botulinum neurotoxins (BoNTs, A-G). The four species have been classified as C. botulinum Groups I-IV. The presence of bont genes in strains representing the different Groups is probably the result of horizontal transfer of the toxin operons between the species. Chromosome and plasmid sequences of several C. botulinum strains representing A, B, E and F serotypes and a C. butyricum type E strain were compared to examine their genomic organization, or synteny, and the location of the botulinum toxin complex genes. These comparisons identified synteny among proteolytic (Group I) strains or nonproteolytic (Group II) strains but not between the two ...
IMMUNOCHEMICAL STUDIES OF ANTITOXIN PRODUCED IN NORMAL AND ALLERGIC INDIVIDUALS HYPERIMMUNIZED WITH DIPHTHERIA TOXOID |...
1. The immunological properties of two contrasting types of human antisera, each containing a high titer of diphtheria antitoxin, have been investigated. 2. Sera which contain only non-precipitating antitoxin exhibit most of the properties of atopic reagin-containing sera. This type of antitoxin is capable of sensitizing normal human skin to toxin or toxoid and remains for many weeks in the injected area. It exhibits no Danysz effect, does not fix complement unless very large amounts of serum are used, and can be specifically coprecipitated by addition of precipitating antitoxin and toxin. On the other hand, it is capable of sensitizing guinea pigs to fatal anaphylactic shock. Heating at 56°C. for 4 hours destroys the skin-sensitizing properties and results in almost quantitative conversion to a modified antitoxin which is capable of blocking the wheal and erythema reaction caused by injection of toxoid into sensitized skin. ...

Welcome to CDC stacks | Optimization of peptide substrates for botulinum neurotoxin E improves detection sensitivity in the...
Botulinum neurotoxins (BoNTs) produced by Clostridium botulinum are the most poisonous substances known to humankind. It is essential to have a simple, quick, and sensitive method for the detection and quantification of botulinum toxin in various media, including complex biological matrices. Our laboratory has developed a mass spectrometry-based Endopep-MS assay that is able to rapidly detect and differentiate all types of BoNTs by extracting the toxin with specific antibodies and detecting the unique cleavage products of peptide substrates. Botulinum neurotoxin type E (BoNT/E) is a member of a family of seven distinctive BoNT serotypes (A-G) and is the causative agent of botulism in both humans and animals. To improve the sensitivity of the Endopep-MS assay, we report here the development of novel peptide substrates for the detection of ...
0038]Botulinum toxin type A can be obtained by establishing and growing cultures of Clostridium botulinum in a fermenter and then harvesting and purifying the fermented mixture in accordance with known procedures. All the botulinum toxin serotypes are initially synthesized as inactive single chain proteins which must be cleaved or nicked by proteases to become neuroactive. The bacterial strains that make botulinum toxin serotypes A and G possess endogenous proteases and serotypes A and G can therefore be recovered from bacterial cultures in predominantly their active form. In contrast, botulinum toxin serotypes C1, D and E are synthesized by nonproteolytic strains and are therefore typically unactivated when recovered from culture. Serotypes B and F are produced by both proteolytic and nonproteolytic strains and therefore can be recovered in ...
In this study we observed an increase of insula activation and involvement of the PPC conjoint with decreased activation of the somatosensory system during self-paced swallowing in a patient suffering from severe dysphagia due to botulism intoxication. A second measurement after clinical recovery showed cortical swallowing processing in the primary and secondary sensorimotor system as well as declined insula activation comparable to the results of a group of healthy control subjects.. To distinguish whether the changed swallowing behaviour is altering brain activation or whether cortical changes are driving the altered behaviour a slow swallowing task was performed by one of the control subjects. This imitation of impaired swallowing behaviour resulted in a slight increase of EMG power, while wavelet and SAM results where comparable to those in the normal swallowing task. We therefore conclude that the changed behaviour in deglutition alone cannot explain the observed changes in cortical ...

The Botulinum neurotoxin serotype A (BoNT/A), a byproduct of the Clostridium botulinum bacteria, is responsible for causing the paralytic disease, Botulism. BoNT/A has a lethal dose (LD50) of 1.3 ng/kg of body weight in humans, making it the worlds most lethal toxin. Its potency, ease of extraction, and reproducibility raises concern the toxin may be weaponized and used in bioterrorism. The therapeutics currently available to treat the disease are not viable for large scale infections, resulting in mass casualties in the case of an attack. Therefore, efforts to develop alternative therapeutics are essential. The toxin is a dimer composed of a heavy chain (HC) and a light chain (LC). The HC binds to neuronal cells and aids the LC into the cytosol of the cell. Once in the cytosol the LC, a zinc metalloprotease, terminates neurotransmission by cleaving SNARE proteins. Our laboratory focuses on the development and synthesis of small molecules as ...

Background: Two decades ago, botulinum neurotoxin (BoNT) type A was introduced to the commercial market. Subsequently, the toxin was approved by the FDA to address several neurological syndromes, involving muscle, nerve, and gland hyperactivity. These syndromes have typically been associated with abnormalities in cholinergic transmission. Despite the multiplicity of botulinal serotypes (designated as types A through G), therapeutic preparations are currently only available for BoNT types A and B. However, other BoNT serotypes are under study for possible clinical use and new clinical indications; Objective: To review the current research on botulinum neurotoxin serotypes A-G, and to analyze potential applications within basic science and clinical settings; Conclusions: The increasing understanding of botulinal neurotoxin pathophysiology, including the neurotoxins effects on specific neuronal populations, will help us in tailoring treatments ...

Botulinum neurotoxins (BoNTs) are extremely potent toxins that are capable of causing death or respiratory failure leading to long-term intensive care. Treatment includes serotype-specific antitoxins, which must be administered early in the course of the intoxication. Rapidly determining human exposure to BoNT is an important public health goal. In previous work, our laboratory focused on developing Endopep-MS, a mass spectrometry-based endopeptidase method for detecting and differentiating BoNT/A-G serotypes in buffer and BoNT/A, /B, /E, and /F in clinical samples. We have previously reported the effectiveness of antibody-capture to purify and concentrate BoNTs from complex matrices, such as clinical samples. Because some antibodies inhibit or neutralize the activity of BoNT, the choice of antibody with which to extract the toxin is critical. In this work, we evaluated a panel of 16 anti-BoNT/A monoclonal ...

In a news release, the Canadian Food Inspection Agency (CFIA) said three people are ill after eating fesikh from Lotus Catering and Fine Food in Toronto. The CFIA said the fish has been recalled because it may be contaminated with Clostridium botulinum, the bacterium that produces toxins which can cause botulism.. Fesikh is a traditional Egyptian fish dish made from mullet, which is dried in the sun until it putrefies and then salted and left to pickle for at least 40 days. Despite annual warnings by health officials against the dangers of fesikh, most Egyptians eat it during the Sham al-Nessim spring celebration.. Cases of food poisoning from incorrectly prepared fesikh are reported each year.. Food contaminated with Clostridium botulinum toxin may not look or smell spoiled. Consumption of food contaminated with the toxin may cause nausea, vomiting, fatigue, dizziness, headache, double vision, dry throat, respiratory ...

Binding agents with differential activity can be provided, whereby certain activities of a first part of the binding agent are reduced or prevented until binding to a target occurs. This is useful if the binding agent is intended to bind both an effector cell and a target to be destroyed, because the effector cell can be protected from significant cell damage that might otherwise occur (e.g. due to premature activation of complement and/or ADCC). Such binding agents are useful in the treatment of cancer, for example.

Botulism is a blood poisoning caused by bacteria known as Clostridium botulism. Ingestion of the toxin produced by the bacteria gives rise to the disease known as botulism. It is not an infection but a poisoning caused by the metabolic by-products of the bacteria. The toxin is possibly produced in living animals but normally in rotting food, carcasses or other organic material and is often carried by maggots; it is primarily a disease of warmer climates where conditions are favorable for the organisms to multiply and produce the botulinal toxin. Man and probably all warm-blooded animals are susceptible to some degree. Certain species are more likely to suffer than others on account of their feeding habits. Some birds such as vultures, which eat rotting carcasses or its associated maggots, appear to be relatively resistant. Waterfowl are most commonly affected, becoming poisoned in hot weather when the bacteria in the mud of stagnant ponds produce large quantities of the toxin. Clinical Signs: ...

The carboxy-terminal domain of the heavy chain recognizes a specific binding site, while the nitrogen-terminus transports the lighter chain into the nerve cytosol (Peck et al. 2010). The lighter chain contains metalloproteases that target specific proteins involved in controlling the exocytosis machinery (Verderio et al. 2006). The inhibition of this integral machinery stops the release of acetylcholine and the neuron fails to send an important signal throughout the body. The lighter chain also decreases the stability of the binding complex, further preventing acetylcholine from being able to bind to the synaptic vesicles (Peck et al. 2010). In addition to releasing neurotoxins when exposed to varying environmental conditions, Clostridium botulinum also increases production of proteases that are secreted from the cell to breakdown polypeptides to contribute to contaminating food and therefore increasing its own toxicity. A large proportion of the bacterias ...
When written, the Professor requested that his name be omitted due to concern for reprisal.. Glyoxylide and associated antitoxins act catalytically, yet the substances themselves are readily oxidized because of the unsaturated double bond linkages, and that is what makes them effective. In this latter respect, the substances differ from true catalysts and enzymes, which are not used up in the process of reaction. It appears as though these antitoxins are so to speak "highly combustible" in the metabolism of animals and their oxidation, therefore can occur at the low oxidative levels which obtain in the sick organism. By analogy, they would have a lower "kindling temperature." And once these metabolites burst into "flame," a great release of energy and radiation occurs which spreads like "wildfire" to toxic substances, which are then burned in their turn. This oxidation then continues from cell to cell in the body in all directions, from many centers of dispersal, operating ...
The paralysis and respiratory failure that occur with botulism may require a patient to be on a breathing machine (ventilator) for weeks, plus intensive medical and nursing care. The paralysis slow improves, usually over several weeks. If diagnosed early, foodborne and wound botulism can be treated with an antitoxin from horse serum which blocks the action of toxin circulating in the blood. This can prevent patients from worsening, but recovery still may take many weeks. ...

Botulinum neurotoxin A (BoNT/A), mainly represented by subtype A1, is the most toxic substance known. It causes naturally-occurring food poisoning, and is among the biological agents at the highest risk of being weaponized. Several antibodies neutralizing BoNT/A by targeting its heavy chain (BoNT/A-H) have been isolated in the past. For the first time however, an IgG (4LCA) recently isolated by hybridoma technology and targeting the BoNT/A light chain (BoNT/A-L), was shown to inhibit BoNT/A endopeptidase activity and protect in vivo against BoNT/A. In the present study, a phage-displayed library was constructed from a macaque (Macaca fascicularis) hyper-immunized with BoNTA/L in order to isolate scFvs inhibiting BoNT/A endopeptidase activity for clinical use. Diversity of the scFvs constituting the library was limited due to the frequent presence, within the genes intended to be part of the library, of restriction sites utilized for its construction. After ...
Fortunately, we have very few, if any, botulism cases associated with foods in the US. Now we only see what is known as "wound botulism." This is what happens when a cut is not cleaned out well and scabs over. In a very few cases, this will provide an ideal environment for the botulism organism to grow. Again, very fortunately this is an extremely rare event…. Many of us believe that home canned foods are probably not as inherently safe as the data might suggest, because almost everyone cooks the food before serving it. Botulism toxin is destroyed by boiling for 10 minutes. So even if the products were improperly canned, people would still be safe because of the cooking. The other nice(?) thing is that there are some spoilage organisms that are even more heat resistant than the one that causes botulism so the food starts to ooze or fizz out of the jar. Most people (but not all, I must report) are sensible enough to throw the stuff out rather than try to eat it." Douglas L. Holt, Ph.D., Chair, ...

Antitoxins are needed that can be produced economically with improved safety and shelf life compared to conventional antisera-based therapeutics. Here we report a practical strategy for development of simple antitoxin therapeutics with substantial advantages over currently available treatments. The therapeutic strategy employs a single recombinant targeting agent that binds a toxin at two unique sites and a clearing Ab that binds two epitopes present on each targeting agent. Co-administration of the targeting agent and the clearing Ab results in decoration of the toxin with up to four Abs to promote accelerated clearance. The therapeutic strategy was applied to two Botulinum neurotoxin (BoNT) serotypes and protected mice from lethality in two different intoxication models with an efficacy equivalent to conventional antitoxin serum. Targeting agents were a single recombinant protein consisting of a heterodimer of two camelid ...

Background. Gene therapy with LentiGlobin Drug Product (DP), which contains autologous CD34+ hematopoietic stem cells transduced with the betibeglogene darolentivec (BB305) lentiviral vector, has been shown to eliminate red blood cell (RBC) transfusions in most patients with TDT with non-β0/β0 genotypes in the prior HGB-204 (Northstar) phase 1/2 study, with a safety profile consistent with myeloablative conditioning. A key finding in HGB-204 was that the average number of therapeutic gene copies per CD34+ cell (i.e. vector copy number [VCN] per diploid genome; median 0.7, range 0.3-1.5) in the DP correlated with peripheral HbAT87Q (transgenic hemoglobin [Hb]) expression at 6 months. To optimize the proportion of patients able to achieve "transfusion independence" and increase unsupported Hb levels after treatment, a refined manufacturing process for LentiGlobin DP was used, to increase the DP VCN and the proportion of transduced cells. Herein, we report initial data from the phase 3 HGB-207 ...
