Botulinum neurotoxin (BoNT), produced by Clostridium botulinum, cleaves proteins involved in neurotransmitter release, thereby triggering flaccid paralyses, which are responsible for botulism. BoNT is classified into seven serotypes (BoNT/A-G); BoNT/A and BoNT/B are used as medical therapeutics and anti-wrinkle reagents. In this study, we investigated the efficacy of BoNT/CD, a mosaic toxin of BoNT/C and BoNT/D, to assess its potential as a therapeutic alternative for BoNT/A. In a cultured neuron assay, BoNT/CD cleaved syntaxin and SNAP-25 with higher efficacy than BoNT/C and BoNT/A. Intramuscularly administrated BoNT/CD induced dose-dependent muscle paralysis, and the paralysis lasted ~21 days in a mouse digit abduction score assay (BoNT/A-induced paralysis lasted ~30 days). BoNT/C failed to induce local paralysis without systemic toxicity. Multiple alignment analyses of the amino acid sequences of the receptor binding domain (HC) of eight BoNT/CDs and two BoNT/Ds showed sequence clustering in five groups. Comparing BoNT/CD strain 003-9 (BoNT/CD003-9) and strain 6813 (BoNT/CD6813) showed that both BoNT/CDs displayed similar efficacies in cultured neurons, but BoNT/CD003-9 displayed higher efficacy in a mouse model than BoNT/CD6813. These findings suggest that BoNT/CD may be a potential alternative for patients who do not respond to existing BoNT-based therapeutics.

<p>We developed “Yezo Venison Sausage” using the characteristics of Yezo sika deer meat to overcome disadvantages associated with the unique smell and tough texture of deer meat to turn Yezo sika deer, a Hokkaido-specific biological resource, into a beneficial resource. “Yezo Venison Sausage” is produced by the addition of 20% minced pork fat, 20% crushed ice, 2.4% salt, 2% sugar, 0.15% color developer, 0.1% ascorbic acid, 0.2% polyphosphate, 0.4% baking soda, 0.6% coarse ground black pepper, 0.2% all spice, and 0.1% sage to minced Yezo sika deer thigh. The ingredients are mixed by hand and then filled into casings made of sheep intestine. After drying at 60°C for 30 min, the sausage is smoked at 60°C for 30 min and then cooked at a central temperature of 70°C for 1 min. The newly developed “Yezo Venison Sausage” shows greatly improved texture and bloody taste quality. Further, the high protein, low fat, and high iron contents, all of which are distinctive characteristics of deer meat, along with the distinctive redness of the meat confer an excellent balance between the sensory and nutritional characteristics of the sausage. </p>
