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.

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

Foodborne botulism from consumption of homemade spoiled eggs: a case series and literature review [PDF]
Botulism is a rare but life-threatening condition that primarily results from ingestion of food contaminated with the exotoxins produced by Clostridium botulinum.

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.

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 ...

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

Toxin-antitoxin (TA) systems are ubiquitous genetic elements that play an essential role in multidrug tolerance and virulence of bacteria. So far, little is known about the TA systems in Streptococcus suis.

Unrelated toxin-antitoxin systems cooperate to induce persistence. [PDF]
Persisters are drug-tolerant bacteria that account for the majority of bacterial infections. They are not mutants, rather, they are slow-growing cells in an otherwise normally growing population.

Much of the diversity of prokaryotic genomes is contributed by the tightly controlled recombination activity of transposons (Tns). The Tn3 family is arguably one of the most widespread transposon families.
