Toxin-Antitoxin Gene Pairs Found in Tn3 Family Transposons Appear To Be an Integral Part of the Transposition Module

open access: yesmBio, 2020
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.

A case of infant botulism in a 4-month-old baby [PDF]

open access: yes, 2016
This case-report highlights: i) the difficulty of IB diagnosis as it is a rare syndrome with subclinical onset, ii) the need for an accurate training for physicians involved in IB management, iii) the efficacy and safety of TEqA in IB treatment, iv ...

THE ANTITOXIN OF TETANUS. [PDF]

open access: yesJAMA: The Journal of the American Medical Association, 1896
Among the many principles on which are based our modern theories of the etiology and therapeutics of disease is that of the vaccinating or immunizing power of attenuated cultures of specific microorganisms. Although this principle is forecast by Jenner's discovery of the vaccine against variola, it is to the great Frenchman, Pasteur, that should be ...

A widespread toxin−antitoxin system exploiting growth control via alarmone signaling

open access: yesProceedings of the National Academy of Sciences of the United States of America, 2020
Significance The alarmone (p)ppGpp is a central signaling nucleotide that is synthesized by RelA-SpoT Homologue (RSH) enzymes, and rewires bacterial physiology in response to stress. It is an unanswered question why bacteria often carry multiple (p)ppGpp-

Large-scale Purification of Type III Toxin-antitoxin Ribonucleoprotein Complex and its Components from Escherichia coli for Biophysical Studies

open access: yesBio-Protocol, 2023
Toxin–antitoxin (TA) systems are widespread bacterial immune systems that confer protection against various environmental stresses. TA systems have been classified into eight types (I–VIII) based on the nature and mechanism of action of the antitoxin ...

Phage ϕC2 mediates transduction of Tn6215, encoding erythromycin resistance, between Clostridium difficile strains [PDF]

open access: yes, 2013
UNLABELLED: In this work, we show that Clostridium difficile phage ϕC2 transduces erm(B), which confers erythromycin resistance, from a donor to a recipient strain at a frequency of 10(-6) per PFU.

An oxygen-sensitive toxin–antitoxin system

open access: yesNature Communications, 2016
Classical toxin–antitoxin systems in bacteria are based on silencing of a toxin by an antitoxin that, when inactivated, releases the toxin, resulting in a change in metabolism. Here, the authors characterize an oxygen-sensitive toxin–antitoxin system and

Two VHH Antibodies Neutralize Botulinum Neurotoxin E1 by Blocking Its Membrane Translocation in Host Cells

open access: yesToxins, 2020
Botulinum neurotoxin serotype E (BoNT/E) is one of the major causes of human botulism, which is a life-threatening disease caused by flaccid paralysis of muscles. After receptor-mediated toxin internalization into motor neurons, the translocation domain (

Small Open Reading Frames, Non-Coding RNAs and Repetitive Elements in Bradyrhizobium japonicum USDA 110 [PDF]

open access: yes, 2016
Small open reading frames (sORFs) and genes for non-coding RNAs are poorly investigated components of most genomes. Our analysis of 1391 ORFs recently annotated in the soybean symbiont Bradyrhizobium japonicum USDA 110 revealed that 78% of them contain ...
