FROZEN TOXIN-ANTITOXIN REACTIONS
JAMA: The Journal of the American Medical Association, 1924To the Editor: —At your request, we make the following statement concerning the effort of freezing on the toxin-antitoxin mixtures in the towns of Concord and Bridgewater, Mass.: A preparation of toxin-antitoxin was used in some forty children in January; the reactions were slight and such as were to be expected. During an intense cold spell, a number

Type II toxin/antitoxin MqsR/MqsA controls type V toxin/antitoxin GhoT/GhoS.
Environmental microbiology, 2014Toxin endoribonucleases of toxin/antitoxin (TA) systems regulate protein production by selectively degrading mRNAs but have never been shown to control other TA systems. Here we demonstrate that toxin MqsR of the MqsR/MqsA system enriches toxin ghoT mRNA in vivo and in vitro, since this transcript lacks the primary MqsR cleavage site 5'-GCU.

Pertussis Toxin-Antitoxin Neutralization Technic
Journal of Infectious Diseases, 1944The method which has been adopted to prepare a standard antitoxic serum is as follows: The crude rabbit serum is titrated by the mouse technic, which will be described later. A portion of this serum is then diluted with saline to a titer of about 200 units per cc.

Chromosomal bacterial type II toxin–antitoxin systems
Canadian Journal of Microbiology, 2012Most prokaryotic chromosomes contain a number of toxin–antitoxin (TA) modules consisting of a pair of genes that encode 2 components, a stable toxin and its cognate labile antitoxin. TA systems are also known as addiction modules, since the cells become “addicted” to the short-lived antitoxin product (the unstable antitoxin is degraded faster than the

Toxin-Antitoxin Systems: Implications for Plant Disease
Annual Review of Phytopathology, 2017Toxin-antitoxin (TA) systems are gene modules that are ubiquitous in free-living prokaryotes. Diverse in structure, cellular function, and fitness roles, TA systems are defined by the presence of a toxin gene that suppresses bacterial growth and a toxin-neutralizing antitoxin gene, usually encoded in a single operon.

Archaeal Type II Toxin-Antitoxins
2012A few of the bacterial type II TA systems, primarily those involved in translational inhibition, occur widely throughout the archaeal domain. Using a bioinformatic approach, the frequency and distribution of these diverse TA loci were examined within completed genomes of 124 archaea that are distributed fairly evenly throughout the major archaeal phyla.

"TISSUE HYPERSENSITIVENESS FOLLOWING TOXIN-ANTITOXIN"
JAMA: The Journal of the American Medical Association, 1927To the Editor: —InThe Journal, April 2, is an article by Drs. Gatewood and Baldridge on "tissue hypersensitiveness following the administration of toxin-antitoxin (phenomenon of Arthus)." The question of whether toxin-antitoxin with its minute amount of antitoxic globulin sensitizes individuals to such a degree that they develop accelerated or more ...

ANAPHYLACTIC PHENOMENA AFTER TOXIN-ANTITOXIN
JAMA: The Journal of the American Medical Association, 1927To the Editor: —I have noted several queries inThe Journalas to the toxicity, if any, from the active immunization against diphtheria by periodic injections of toxin-antitoxin mixture. I have immunized a few thousand children during the last four years, without any definite reaction till recently.

2012
The toxIN locus from a cryptic plasmid of the plant pathogen Pectobacterium atrosepticum was the first type III toxin–antitoxin (TA) system to be identified. This new paradigm describes how an RNA antitoxin directly interacts with and inhibits a protein toxin.
