A pragmatic harm reduction approach to manage a large outbreak of wound botulism in people who inject drugs, Scotland 2015 [PDF]

, 2018
Background People who inject drugs (PWID) are at an increased risk of wound botulism, a potentially fatal acute paralytic illness. During the first 6 months of 2015, a large outbreak of wound botulism was confirmed among PWID in Scotland, which resulted ...

Toxin-Antitoxin Systems and Persistence

, 2019
Toxin-antitoxin (TA) systems are small genetic modules comprising a stable toxic protein and an antitoxin preventing the toxin activity. In type II TA systems, antitoxins are unstable proteins that are degraded by host ATP-dependent proteases. In steady-state conditions, the antitoxin forms a complex with the toxin in which the toxic activity is ...

Type II Toxin-Antitoxin Systems: Evolution and Revolutions

Journal of Bacteriology, 2020
Type II toxin-antitoxin (TA) systems are small genetic elements composed of a toxic protein and its cognate antitoxin protein, the latter counteracting the toxicity of the former. While TA systems were initially discovered on plasmids, functioning as addiction modules through a phenomenon called postsegregational killing, they were later shown to be ...

Escherichia coli EHEC Germany outbreak preliminary functional annotation using BG7 system [PDF]

, 2011
We have annotated the European outbreak E. coli EHEC genome sequenced by BGI (6-2-2011) and assembled with MIRA by Nick Loman (6-2-2011 ). Our system BG7, Bacterial Genome annotation of Era7 Bioinformatics, predicts ORFs and annotates them based on ...

Characterization of a Streptococcus mutans intergenic region containing a small toxic peptide and its cis-encoded antisense small RNA antitoxin. [PDF]

PLoS ONE, 2013
Toxin-antitoxin (TA) modules consist of a pair of genes that encode two components: a protein toxin and an antitoxin, which may be in the form of either a labile protein or an antisense small RNA. Here we describe, to the best of our knowledge, the first

Stay or Go: Sulfolobales Biofilm Dispersal Is Dependent on a Bifunctional VapB Antitoxin

mBio, 2023
A type II VapB14 antitoxin regulates biofilm dispersal in the archaeal thermoacidophile Sulfolobus acidocaldarius through traditional toxin neutralization but also through noncanonical transcriptional regulation.

Regulation of toxin–antitoxin systems by proteolysis

Plasmid, 2013
Toxin-antitoxin systems are widely distributed among many bacterial species, including human pathogens. Typically, these systems consist of two genes in an operon which encodes a stable toxin disrupting essential cellular processes and a labile antitoxin preventing toxicity.

Orphan Toxin OrtT (YdcX) of Escherichia coli Reduces Growth during the Stringent Response

Toxins, 2015
Toxin/antitoxin (TA) systems are nearly universal in prokaryotes; toxins are paired with antitoxins which inactivate them until the toxins are utilized. Here we explore whether toxins may function alone; i.e., whether a toxin which lacks a corresponding ...

Association Between Toxin-Antitoxin Systems and Biofilm Formation [PDF]

Jundishapur Journal of Microbiology, 2014
Toxin-antitoxin (TA) systems are found on the chromosomes and plasmids of many Bacteria such as Escherichia coli. The roles of TA systems in bacteria are enigmatic. Multiple biological functions of TA systems are proposed including growth modulation, persistence, and biofilm formation. Biofilms of E.

Molecular Characterization of Protease Activity in Serratia sp. Strain SCBI and Its Importance in Cytotoxicity and Virulence [PDF]

, 2014
A newly recognized Serratia species, termed South African Caenorhabditis briggsae isolate (SCBI), is both a mutualist of the nematode Caenorhabditis briggsae KT0001 and a pathogen of lepidopteran insects. Serratia sp.
