Medical Countermeasures against Ricin Intoxication

open access: yesToxins, 2023
Ricin toxin is a disulfide-linked glycoprotein (AB toxin) comprising one enzymatic A chain (RTA) and one cell-binding B chain (RTB) contained in the castor bean, a Ricinus species.

Clostridium and Bacillus Binary Enterotoxins: Bad for the Bowels, and Eukaryotic Being

open access: yesToxins, 2014
Some pathogenic spore-forming bacilli employ a binary protein mechanism for intoxicating the intestinal tracts of insects, animals, and humans. These Gram-positive bacteria and their toxins include Clostridium botulinum (C2 toxin), Clostridium difficile (

AB 5 Preassembly Is Not Required for Shiga Toxin Activity [PDF]

open access: yesJournal of Bacteriology, 2016
ABSTRACT Shiga toxin (Stx)-producing Escherichia coli (STEC) is a major cause of foodborne illness, including the life-threatening complication hemolytic-uremic syndrome. The German outbreak in 2011 resulted in nearly 4,000 cases of infection, with 54 deaths.

Role of Homologous Fc Fragment in the Potency and Efficacy of Anti‐Botulinum Antibody Preparations

open access: yesToxins, 2017
The only approved treatment for botulism relies on passive immunity which is mostly based on antibody preparations collected from hyper‐immune horses. The IgG Fc fragment is commonly removed from these heterologous preparations to reduce the incidence of

Purification and some properties of Clostridium botulinum type AB toxin [PDF]

open access: yesFEMS Microbiology Letters, 1986
Abstract The progenitor toxin of Clostridium botulinum type AB was purified; both large-sized (L) and medium-sized (M) toxins were found. The toxicity of M toxin increased by about 10-fold upon trypsinization; the increase was due mostly to type B toxin and a little to type A toxin.

Production, Characterisation and Testing of an Ovine Antitoxin against Ricin; Efficacy, Potency and Mechanisms of Action

open access: yesToxins, 2017
Ricin is a type II ribosome-inactivating toxin that catalytically inactivates ribosomes ultimately leading to cell death. The toxicity of ricin along with the prevalence of castor beans (its natural source) has led to its increased notoriety and ...

Pharmacological inhibition of host cell neddylation reduces intoxication of cells by diphtheria toxin and clostridial enterotoxins TcdB and C2

open access: yesMicrobiology Spectrum
NEDD8 is a ubiquitin-like molecule that is conjugated to lysine residues of protein substrates in a process known as neddylation, which affects their stability, degradation, and interactions.

Uptake and Processing of the Cytolethal Distending Toxin by Mammalian Cells

open access: yesToxins, 2014
The cytolethal distending toxin (Cdt) is a heterotrimeric holotoxin produced by a diverse group of Gram-negative pathogenic bacteria. The Cdts expressed by the members of this group comprise a subclass of the AB toxin superfamily.
