The supply of synaptic vesicles in the nerve terminal is maintained by a temporally linked balance of exo- and endocytosis. Tetanus and botulinum neurotoxins block neurotransmitter release by the enzymatic cleavage of proteins identified as critical for synaptic vesicle exocytosis. We show here that botulinum neurotoxin A is unique in that the toxin-induced block in exocytosis does not arrest v...

BACKGROUND Botulinum neurotoxin treatment is the most common aesthetic procedure in the United States. A number of serotypes and formulations are available worldwide. Similarities and differences among these toxins were evaluated by reviewing the existing literature. METHODS Reports of botulinum neurotoxin for aesthetic use, published in peer-reviewed literature or presented at recent profess...

The rapidly growing number of botulinum neurotoxin sequences poses the problem of the possible evolutionary significance of the variability of these superpotent neurotoxins for toxin-producing Clostridium species. To progress in the understanding of this remarkable phenomenon, we suggest that researchers should (i) abandon an anthropocentric view of these neurotoxins as human botulism-causing a...

background: food-born botulism is caused by ingestion of contaminated food with clostridium botulinum neurotoxin. case: in food-born botulism, due to acetylcholine release blockade, neuromuscular signs and symptoms are common, but in this case report we present a food-born botulism with papiledema and venous sinus thrombosis. conclusion: papiledema and fever could not rule out the diagnosis of ...

Botulism is neuromuscular paralysis secondary to a neurotoxin secreted from Clostridium Botulinum bacteria. It is a rare syndrome that results from food poisoning with the spore-forming clostridium bacteria. The ingested food is contaminated with the pre-secreted botulinum toxin. Infant botulism occurs with the ingestion of the clostridia spores that later germinate and colonize the intestine a...
