Comparison of toxins of Clostridium butyricum and Clostridium botulinum type E.

Characterization of a neurotoxigenic Clostridium butyricum strain isolated from the food implicated in an outbreak of food-borne type E botulism.

Neurotoxigenic Clostridium butyricum was isolated from the food implicated in an outbreak of clinically diagnosed type E botulism in China. PCR assay showed that the isolate (LCL 155) contained the type E botulinum toxin gene. This appears to be the first report of neurotoxigenic C. butyricum causing food-borne botulism.

Genetic analysis of type E botulinum toxin-producing Clostridium butyricum strains.

Type E botulinum toxin (BoNT/E)-producing Clostridium butyricum strains isolated from botulism cases or soil specimens in Italy and China were analyzed by using nucleotide sequencing of the bont/E gene, random amplified polymorphic DNA (RAPD) assay, pulsed-field gel electrophoresis (PFGE), and Southern blot hybridization for the bont/E gene. Nucleotide sequences of the bont/E genes of 11 Chines...

Finished Whole-Genome Sequences of Clostridium butyricum Toxin Subtype E4 and Clostridium baratii Toxin Subtype F7 Strains

Clostridium butyricum and Clostridium baratii species have been known to produce botulinum toxin types E and F, respectively, which can cause botulism, a rare but serious neuroparalytic disease. Here, we present finished genome sequences for two of these clinically relevant strains.

Double 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...
