Epsilon toxin: a fascinating pore‐forming toxin

The FEBS Journal, 2011
Epsilon toxin (ETX) is produced by strains of Clostridium perfringens classified as type B or type D. ETX belongs to the heptameric β‐pore‐forming toxins including aerolysin and Clostridium septicum alpha toxin, which are characterized by the formation of a pore through the plasma membrane of eukaryotic cells consisting in a β‐barrel of 14 amphipatic β

Clostridium perfringens epsilon toxin: The third most potent bacterial toxin known

Anaerobe, 2014
Epsilon toxin (ETX) is produced by Clostridium perfringens type B and D strains and causes enterotoxemia, a highly lethal disease with major impacts on the farming of domestic ruminants, particularly sheep. ETX belongs to the aerolysin-like pore-forming toxin family.

Cellular effects of epsilon toxin on the cell viability and oxidative stress of normal and lung cancer cells.

Microbial Pathogenesis, 2022
INTRODUCTION Clostridium perfringens is a type of gram-positive anaerobic bacilli. C.perfringens produces many toxins, of which epsilon (ε) is one of the major ones.

Clostridium perfringens epsilon-toxin requires acid sphingomyelinase for cellular entry.

Anaerobe, 2023
OBJECTIVES Clostridium perfringens epsilon-toxin is considered to be a crucial agent in enterotoxemia in domestic animals. Epsilon-toxin enters host cells via endocytosis and results in the formation of late endosome/lysosome-derived vacuoles.

Neurological disorders produced by Clostridium perfringens type D epsilon toxin

Anaerobe, 2004
Although the epsilon toxin of Clostridium perfringens type D produces disease in many species of domestic livestock, neurological disturbance is more common and better studied in sheep. High levels of circulating toxin, especially in lambs, cause cerebral microvascular endothelial damage with disruption of the blood-brain barrier leading to a severe ...

Development and evaluation of cell membrane-based biomimetic nanoparticles loaded by Clostridium perfringens epsilon toxin: a novel vaccine delivery platform for Clostridial-associated diseases

Nanotoxicology, 2023
As Clostridium perfringens (C. perfringens) epsilon toxin (ETX) ranks as the third most potent clostridial toxin after botulinum and tetanus toxins, vaccination is necessary for creatures that can be affected by it to be safe from the effects of this ...

Amino groups in Clostridium perfringens epsilon prototoxin and epsilon toxin

Microbial Pathogenesis, 1986
Modification with succinic anhydride (SA) of Clostridium perfringens epsilon prototoxin or toxin resulted in a loss of activation by trypsin or lethal activity, respectively. The prototoxin was more sensitive to succinylation than the toxin. On the other hand, the succinylated prototoxin was activated and cleaved by chymotrypsin, but not by trypsin ...
