Chaperone addiction of toxin–antitoxin systems
Some bacterial toxin-antitoxin systems consist of a labile antitoxin that inhibits a toxin, and a chaperone that stabilizes the antitoxin. Here, Bordes et al.

Structural insights into chaperone addiction of toxin-antitoxin systems [PDF]
SecB homologs can be associated with stress-responsive type II toxin–antitoxin (TA) systems and form tripartite toxin-antitoxin-chaperone systems (TAC).

A Case of Botulism Fast Adjusting with Antitoxin Administration in the Early Period and the Use of Electromyography in Diagnosis [PDF]
Botulism is a rare but potentially life-threatening neuroparalytic syndrome caused by the action of a neurotoxin caused by the bacterium Clostridium botulinum. Early diagnosis and early treatment is important. In cases where botulism occurs sporadically,

Toxin–Antitoxin Systems in Pathogenic Bacteria [PDF]
© 2021 by the authorToxin–antitoxin (TA) systems, which are ubiquitously present in plasmids, bacterial and archaeal genomes, are classified as types I to VI, according to the nature of the antitoxin and to the mode of toxin inhibition [1–5].

Ricin, produced from the castor beans of Ricinus communis, is a cytotoxin that exerts its action by inactivating ribosomes and causing cell death. Accidental (e.g., ingestion of castor beans) and/or intentional (e.g., suicide) exposure to ricin through ...

RNA antitoxin SprF1 binds ribosomes to attenuate translation and promote persister cell formation in Staphylococcus aureus [PDF]
Persister cells are a subpopulation of transiently antibiotic-tolerant bacteria associated with chronic infection and antibiotic treatment failure. Toxin-antitoxin systems have been linked to persister cell formation but the molecular mechanisms leading ...

Post-Exposure Anti-Ricin Treatment Protects Swine against Lethal Systemic and Pulmonary Exposures
Ricin, a plant-derived toxin originating from the seeds of Ricinus communis (castor bean plant), is one of the most lethal toxins known. To date, there is no approved post-exposure therapy for ricin exposures.

Modeling sRNA-Regulated Plasmid Maintenance. [PDF]
We study a theoretical model for the toxin-antitoxin (hok/sok) mechanism for plasmid maintenance in bacteria. Toxin-antitoxin systems enforce the maintenance of a plasmid through post-segregational killing of cells that have lost the plasmid.

Investigation of the Frequency of Foodborne Botulism in Patients Referred to Loghman Hospital in Tehran City, Iran, From 2008 to 2019 [PDF]
Background: Foodborne botulism is a fatal paralytic illness caused mainly by the neurotoxin produced by an anaerobic bacterium called Clostridium botulinum. In this study, the frequency of foodborne botulism in patients referred to a hospital in Iran has
