In vitro potency test for evaluation of Clostridium perfringens type D epsilon toxoid
The control of enterotoxemia caused by the epsilon toxin, produced by Clostridium perfringenstype D, is based on vaccination with epsilon toxoid. The potency test for this immunogen is conducted using seroneutralization in mice.

Modulation of ecdysal cyst and toxin dynamics of two Alexandrium (Dinophyceae) species under small-scale turbulence [PDF]
Some dinoflagellate species have shown different physiological responses to certain turbulent conditions. Here we investigate how two levels of turbulent kinetic energy dissipation rates (epsilon = 0.4 and 27 cm(2) s(-3)) affect the PSP toxins and ...

Conductance increases produced by bath application of cholinergic agonists to Electrophorus electroplaques [PDF]
When solutions containing agonists are applied to the innervated face of an Electrophorus electroplaque, the membrane's conductance increases. The agonist-induced conductance is increased at more negative membrane potentials.

Biochemical and Pharmacological Studies of Clostridium perfringens .EPSILON.-Toxin.
D型ウエルシュ菌のe毒素は, 致死, 壊死作用を有するタンパク毒素で, 本菌によるヒツジの腸性中毒症の病原因子と考えられている。本研究では, e毒素の作用機構解明の手がかりを得るため, e毒素の in vivo と in vitro における作用, さらに構造と機能について検討した。まず, e毒素をラットに投与すると末梢血管の収縮による急激な血圧上昇が認められること, さらに本毒素は, in vitro で血管, 回腸などの摘出平滑筋組織を収縮させることを明らかにした。この作用は毒素が神経系にNa+の流入を促進し, その結果, 神経伝達物質が遊離, そしてCa2+チャンネルが活性化されて引き起こされることが判明した。一方, e毒素は脳組織において1種類のシアロ糖タンパク質に特異的に結合すること ...

The Clostridium perfringens epsilon toxin, a select agent, is responsible for a severe, often fatal enterotoxemia characterized by edema in the heart, lungs, kidney, and brain. The toxin is believed to be an oligomeric pore-forming toxin.

The Clostridium perfringens Epsilon Toxin as a Bioterrorism Weapon [PDF]
The Clostridium perfringens epsilon toxin made by the microorganism true bacteria could be a doubtless fatal bioterrorism weapon. If used effectively, this agent might cause important morbidity and mortality and, because of a scarcity of existing analysis into the result of this poison in humans, no therapeutic or preventive measures exist as medical ...

Cryo-EM structure of lysenin pore elucidates membrane insertion by an aerolysin family protein [PDF]
Lysenin from the coelomic fluid of the earthworm Eisenia fetida belongs to the aerolysin family of small β-pore-forming toxins (β-PFTs), some members of which are pathogenic to humans and animals. Despite efforts, a high-resolution structure of a channel
