botulism/carbohydrate

In skeletal muscle under a local botulinic intoxication and denervation the alterations in metabolism of glycogen, phosphocreatine, lactic and pyruvic acids were studied. The data obtained suggest that the dissimilarity in impairments of carbohydrate-energy metabolism in botulism and denervation was

Content of lactic and pyruvic acids, glycogen, sodium and potassium ions are well as the total LDH activity and its isoenzyme spectrum were not distinctly altered, when secretion of salivary glands was inhibited by administration of botulinic toxin into rats (within 48 hrs after the toxin

Botulinum neurotoxins (BoNTs) cause the disease botulism manifested by flaccid paralysis that could be fatal to humans and animals. Oral ingestion of the toxin with contaminated food is one of the most common routes for botulism. BoNT assembles with several auxiliary proteins to survive in the

A rapid competitive RT/PCR assay was developed to determine the effects of nutrients on Clostridium botulinum type E toxin gene expression. The type E strain (EVH) was grown in a nutrient-rich broth containing 1% glucose (base medium). Toxin gene expression was quantified at both mid and late

Botulinum neurotoxin (BoNT) inhibits neurotransmitter release in motor nerve endings, causing botulism, a condition often resulting from ingestion of the toxin or toxin-producing bacteria. BoNTs are always produced as large protein complexes by associating with a non-toxic protein, non-toxic

Botulism food poisoning is caused primarily by ingestion of the Clostridium botulinum neurotoxin (BoNT). The 1300 amino acid BoNT forms a progenitor toxin (PTX) that, when associated with a number of other proteins, increases its oral toxicity by protecting it from the low pH of the stomach and from

Twenty-two lactating Holstein cattle in Tennessee had clinical signs of intoxication with preformed Clostridium botulinum toxin. These signs included weakness, paralysis of the tongue and chest muscles, abdominal breathing, and, in 11 of the 22 cows, death. Differential diagnoses included

Botulinum neurotoxins (BoNTs) and tetanus neurotoxin (TeNT) are the causative agents of the paralytic diseases botulism and tetanus, respectively. Entry of toxins into neurons is mediated through initial interactions with gangliosides, followed by binding to a protein co-receptor. Herein, we aimed

Botulinum neurotoxin produced by Clostridium botulinum type B is in the form of a complex of 12S and 16S toxins. Food-borne botulism is caused by these complex toxins which are ingested orally and absorbed from the digestive tract. Here, we show that the human milk SIgA binds to the type B16S toxin.

Clostridium butyricum, the type species of the genus Clostridium, is considered an obligate anaerobe, yet it has been shown to grow in the presence of oxygen. C. butyricum strains atypically producing the botulinum neurotoxin type E are the leading cause of type E human botulism in

Foodborne pathogenic bacteria are exposed to a number of environmental stresses during food processing, storage, and preparation, and in the human body. In order to improve the safety of food, the understanding of molecular stress response mechanisms foodborne pathogens employ is essential. Many

Botulinum neurotoxins (BoNTs) are produced as progenitor toxin complexes (PTCs) by Clostridium botulinum. The PTCs are composed of BoNT and non-toxic neurotoxin-associated proteins (NAPs), which serve to protect and deliver BoNT through the gastrointestinal tract in food borne botulism. HA33 is a

Botulinum neurotoxin (BoNT), produced by Clostridium botulinum, is the most potent toxin and produced as a complex with non-toxic components. Food-borne botulism is caused by the ingestion of these BoNT complexes. Hemagglutinin (HA), one of the non-toxic components, is known to have lectin

A large number of intellectually engaging and potentially serious neuromuscular diseases have been presented. The emergency medicine physician must be able to recognize those entities that have the potential to clinically deterioration. The evaluation of weakness requires a comprehensive,

Botulinum neurotoxins (BoNTs) are produced by Clostridium botulinum and cause the fatal disease botulism, a flaccid paralysis of the muscle. BoNTs are released together with several auxiliary proteins as progenitor toxin complexes (PTCs) to become highly potent oral poisons. Here, we report the
