Immunogenic and Protective Potentials of Recombinant Receptor Binding Domain and a C-Terminal Fragment of Clostridium botulinum Neurotoxin Type E
Clostridium Botulinum Type E neurotoxin heavy chain consists of two domains: the translocation domain asthe N-terminal half and the binding domain as the Cterminal half (Hc). One effective way to neutralize botulinum neurotoxin is to inhibit binding of this toxin to neuromuscular synapses with antibodies against binding domain. Two synthetic genes, coding for Hc (the full length binding d...
متن کاملCharacterization of Clostridium botulinum spores and its toxin in honey
Botulism is a serious paralytic disease caused by Clostridium botulinum toxin in foods. There are seven recognized serotypes of botulinum neurotoxins among which the principal prevalent types in humans include A, B and E. Infant botulism results from intestinal colonization and toxin production by C. botulinum spores in babies less than 1 year old. Honey is the most important food discriminated...
متن کاملStructural analysis by X-ray crystallography and calorimetry of a haemagglutinin component (HA1) of the progenitor toxin from Clostridium botulinum.
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 intestinal proteases. One of these associated proteins, HA1, has also been suggested to be invol...
متن کاملDouble Sandwich ELISA Modified Method for the Detection of Clostridium Botulinum Type E
Background & Objective: A very small amount of botulinum toxin can cause death and on the other hand, there is no cure for its poison other than antitoxin. Therefore, a diagnostic method that can detect very small amounts of botulinum toxin in a short time is very important. In this study, rapid and accurate detection of botulinum toxin type E has been performed with the double sandwich ELISA m...
متن کاملCellular Entry of Clostridium perfringens Iota-Toxin and Clostridium botulinum C2 Toxin
Clostridium perfringens iota-toxin and Clostridium botulinum C2 toxin are composed of two non-linked proteins, one being the enzymatic component and the other being the binding/translocation component. These latter components recognize specific receptors and oligomerize in plasma membrane lipid-rafts, mediating the uptake of the enzymatic component into the cytosol. Enzymatic components induce ...
