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.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.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.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, Type A: A serotype of botulinum toxins that has specificity for cleavage of SYNAPTOSOMAL-ASSOCIATED PROTEIN 25.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.Clostridium botulinum type B: Subtype of CLOSTRIDIUM BOTULINUM that produces botulinum toxin type B which is neurotoxic to humans and animals.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.Botulinum Antitoxin: Antiserum given therapeutically in BOTULISM.Clostridium Infections: Infections with bacteria of the genus CLOSTRIDIUM.Clostridium botulinum type D: Subtype of CLOSTRIDIUM BOTULINUM that produces botulinum toxin type D which is neurotoxic to ANIMALS, especially CATTLE, but not humans.Clostridium botulinum type F: Subtype of CLOSTRIDIUM BOTULINUM that produces botulinum toxin type F which is neurotoxic to humans and animals.ADP Ribose Transferases: Enzymes that transfer the ADP-RIBOSE group of NAD or NADP to proteins or other small molecules.

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.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.Antitoxins: Antisera from immunized animals that is purified and used as a passive immunizing agent against specific BACTERIAL TOXINS.Food Irradiation: Treatment of food with RADIATION.Bacterial Toxins: Toxic substances formed in or elaborated by bacteria; they are usually proteins with high molecular weight and antigenicity; some are used as antibiotics and some to skin test for the presence of or susceptibility to certain diseases.Lethal Dose 50: The dose amount of poisonous or toxic substance or dose of ionizing radiation required to kill 50% of the tested population.Anti-Dyskinesia Agents: Drugs used in the treatment of movement disorders.

Type B botulinum2
- A sample of the patient's serum collected before antitoxin administration demonstrated the presence of type B botulinum toxin. (cdc.gov)
- The effects of carbon dioxide, sodium chloride, and sodium nitrite on type B botulinum neurotoxin (BoNT/B) gene ( cntB ) expression in nonproteolytic Clostridium botulinum were investigated in a tryptone-peptone-yeast extract (TPY) medium. (asm.org)
Acquired the toxin1
- C. botulinum is a lipase-positive microorganism that grows between pH of 4.8 and 7.0 and cannot use lactose as a primary carbon source, characteristics important for biochemical identification. (wikipedia.org)
- Nitrite and salt inhibit the growth of Clostridium botulinum , a deadly microorganism which can occur in foods under certain situations. (usda.gov)
- The correct acid concentration, in the form of vinegar, is important because acid prevents the growth of Clostridium botulinum, a deadly microorganism, in quick process pickles. (osu.edu)
- In humans, the toxin latches onto specific proteins in nerve endings and irreversibly destroys them. (thehealthsuccesssite.com)
- In contrast to TeNT, BoNTs are associated to non-toxic proteins (ANTPs) to form highly stable botulinum complexes. (caister.com)
- Without causing an actual infection, vaccines introduce weakened or detoxified versions of disease-related proteins to the immune system, which remembers to destroy them upon their next encounter. (blogspot.com)
- Food that has been improperly preserved or stored can harbor botulinum toxin-producing clostridia. (thehealthsuccesssite.com)
- Safe food preservation methods destroy spores or inhibit their germination and growth. (cdc.gov)
- BSM agar is a selective and differential media used for the presumptive identification of Clostridium botulinum from food or fecal samples. (anaerobesystems.com)
- BSM supports good growth of Clostridium botulinum from food or clinical infections. (anaerobesystems.com)
- Research published earlier this year, also in the journal Current Microbiology , indicated that glyphosate formulations , at concentrations lower than presently used in agricultural applications, are capable of destroying food organisms widely used as starters in traditional and industrial dairy technologies, such as Geotrichum candidum, Lactococcus lactis subsp. (healthimpactnews.com)
- The Food Safety and Inspection Service (FSIS) is proposing to amend the Federal meat inspection regulations to eliminate the requirements for both ready-to-eat (RTE) and not-ready-to-eat (NRTE) pork and pork products to be treated to destroy trichinae ( Trichinella spiralis ) because the regulations are inconsistent with the Hazard Analysis and Critical Control Point (HACCP) regulations, and because these prescriptive regulations are no longer necessary. (federalregister.gov)
- Control of C. botulinum in food products requires destruction of the spores through processing or prevention of growth through formulation, temperature control, or a combination of these factors. (ecolab.com)
- The toxin is generally destroyed by heating or boiling food for a sufficient amount of time, however the spores are heat resistant and require very high temperature treatments before they are safe to consume. (calpoison.org)
- As such, safe canning procedures often require pressurization in addition to boiling which can kill off the spores and prevent production of botulinum in food products. (drlam.com)
- these measures include adjustment of the pH and addition of sodium chloride and other food preservatives to prevent growth and formation of neurotoxin by C. botulinum . (asm.org)
Production of antibodies2
- In broad usage, any substance or entity which the body recognizes as foreign and induces the production of antibodies to neutralize or destroy the antigen. (bdipharma.com)
- Vaccines stimulate the immune system s production of antibodies that identify and destroy disease-causing organisms that enter the body. (reportsnreports.com)
- However, C. botulinum tolerates traces of oxygen due to the enzyme superoxide dismutase, which is an important antioxidant defense in nearly all cells exposed to oxygen. (wikipedia.org)
- In the laboratory, C. botulinum is usually isolated in tryptose sulfite cycloserine (TSC) growth medium in an anaerobic environment with less than 2% oxygen. (wikipedia.org)
- C. botulinum thrives in moist foods that are low in salt (less than 10%), particularly when they are stored at temperatures above 38°F. These organisms will not grow in an aerobic environment, but other aerobic organisms in a closed system can rapidly convert an aerobic environment to an anaerobic environment by using the oxygen for their own growth, permitting growth of C. botulinum . (uga.edu)
- Clostridia, as a family, are obligate anaerobes, meaning that oxygen is toxic to them. (videosliv.com)
- C. botulinum grows under anaerobic (no oxygen) conditions. (ecolab.com)
- High levels of oxygen, high amounts of sugar, high acidity, extremely low moisture and low temperature below 3 degree Celsius inhibit the growth and production of Clostridium botulinum spores and toxins. (drlam.com)
- The pH of the pickling liquid was 3.5 (i.e., adequate to prevent C. botulinum germination and toxin formation. (cdc.gov)
- In previous studies on C. botulinum workers have focused mainly on the germination and outgrowth of spores in both microbiological growth medium and different foods ( 10 , 18 , 22 , 27 ). (asm.org)
