Botulinum toxin: Wikis From Wikipedia, the free encyclopedia. Botulinum toxin is a medication and a neurotoxic protein produced by the bacterium Clostridium botulinum, and is known to be very toxic with an LD50 of roughly 0.005–0.05 µg/kg. Despite its deadly toxic effect, it is sometimes used in very small doses to treat muscle spasms.

ArticleCoordinate regulation of siderophore and diphtheria toxin production by iron in Corynebacterium diphtheriae â In response to iron-deprivation, lysogenic Corynebacterium diphtheriae C7(β) synthesizes and secretes diphtheria toxin and siderophore and induces a high-affinity iron uptake system. Diphtheria toxin is encoded by β phage, but genes for siderophore production are encoded on the bacterial chromosome. Diphtheria toxin and siderophore production were shown to be coordinately induced during late logarithmic phase growth of wild-type C7(β) in iron-limited medium.

BOTULINUM TOXIN Botulinum toxin, one of the most poisonous biological substances known, is a neurotoxin produced by the bacterium Clostridium botulinum. C. botulinum elaborates eight antigenically distinguishable exotoxins (A, B, C 1, C 2, D, E, F and G).

Vibrio cholerae V. cholerae pathogenicity genes code for proteins directly or indirectly involved in the virulence of the bacteria. During infection, V. cholerae secretes cholera toxin, a protein that causes profuse, watery diarrhea.. cholerae was first isolated as the cause of cholera by Italian anatomist Filippo Pacini in 1854, but his discovery was not widely known until Robert Koch, working independently 30 years later, publicized the knowledge and the means of fighting the disease.

Vibrio cholerae Vibrio cholerae is a Gram-negative, comma-shaped bacterium. Some strains of V. cholerae cause the disease cholera. V. cholerae is a facultative anaerobic organism and has a flagellum at one cell pole.holera infections are most commonly acquired from drinking water in which V. cholerae is found naturally or into which it has been introduced from the feces of an infected person. Other common vehicles include contaminated fish and shellfish, produce, or leftover cooked grains that have not been properly reheated.

BOTULINUM TOXIN Introduction. Botulinum toxin, also called “miracle poison,” is one of the most poisonous biological substances known.[ 1 ] It is a neurotoxin produced by the bacterium Clostridium botulinum, an anaerobic, gram-positive, spore-forming rod commonly found on plants, in soil, water and the intestinal tracts of animals.

- Cholera is highly contagious. Cholera can be transferred person to person by infected fecal matter entering a mouth or by water or food contaminated with Vibrio cholerae bacteria.holera causes profuse diarrhea episodes and vomiting. The cause of cholera are toxins secreted by the Vibrio cholerae bacteria. Microscopically, these bacteria appear curved (comma-shaped) and have a negative Gram stain.

Scientific Name for Cholera Vibrio cholerae is a type of bacteria that cause cholera (an acute, diarrheal illness that can result in severe dehydration and even death within a matter of hours).These are Gram-negative rods (see Pictures of Cholera) that are facultatively anaerobic, which means they can survive either with or without oxygen.ibrio cholerae Serogroup O1 is the bacteria that is most often the cause of cholera. Vibrio cholerae Serogroup O139, a Vibrio cholerae Serogroup non-O1 bacterium, is the other cause of cholera. There are about 70 other species of Vibrio cholerae Serogroup non-O1; these other species rarely cause diarrhea.

Shiga-like toxin Shiga-like toxin , also known as verotoxin and verocytotoxin , is a toxin generated by some strains of Escherichia coli (but see below ). It is named for its similarity to the AB5-type Shiga toxin produced by the bacteria Shigella dysenteriae (see Vero cell ). There are two types, known as SLT1 and SLT2.

- Abstract The toxin ss-N-methylamino-L-alanine (BMAA) was proposed to contribute to the ALS/Parkinsonism-dementia complex of Guam (ALS/PDC) based on its presence in cycad seeds, which constituted a dietary item in afflicted populations, and its ability to induce a similar disease phenotype in primates.n past studies we found that toxic and excitatory effects of BMAA on cultured neurons were dependent upon the presence of bicarbonate in the medium, and suggested that formation of a carbamate adduct of the side-chain amino group might produce structures capable of activating glutamate receptors.

Lipid A Chemical structure of lipid A as found in E. coli. Lipid A is a lipid component of an endotoxin held responsible for the toxicity of gram-negative bacteria. It is the innermost of the three regions of the lipopolysaccharide (LPS), also called endotoxin molecule, and its hydrophobic nature allows it to anchor the LPS to the outer membrane.

Vibrio Cholerae Bacteria Vibrio cholerae bacteria can cause cholera, which is an acute, diarrheal illness that can result in severe dehydration and even death within a matter of hours. Vibrio cholerae bacteria are gram-negative rods (see Pictures of Cholera) that are facultatively anaerobic.ibrio cholerae bacteria then begin to produce their toxin, which is the main cause of the characteristic cholera symptom: watery diarrhea. A person needs to ingest a lot of Vibrio cholerae bacteria in order to develop symptoms of cholera.
