Keeping the wolves at bay: antitoxins of prokaryotic type II toxin-antitoxin systems

Frontiers in Molecular Biosciences, 2016
In their initial stages of discovery, prokaryotic toxin-antitoxin (TA) systems were confined to bacterial plasmids where they function to mediate the maintenance and stability of usually low- to medium-copy number plasmids through the post-segregational ...

Viral evasion of a bacterial suicide system by RNA-based molecular mimicry enables infectious altruism.

PLoS Genetics, 2012
Abortive infection, during which an infected bacterial cell commits altruistic suicide to destroy the replicating bacteriophage and protect the clonal population, can be mediated by toxin-antitoxin systems such as the Type III protein-RNA toxin-antitoxin

Toxin-antitoxin genes are differentially expressed in Escherichia coli relA and spoT mutans cultured under nitrogen, fatty acid, or carbon starvation conditions

Frontiers in Microbiology
IntroductionThe stringent response is one of the fundamental mechanisms that control and modulate bacterial adaptation to stress conditions, such as nutrient limitation.

Determination of low tetanus or diphtheria antitoxin titers in sera by a toxin neutralization assay and a modified toxin-binding inhibition test

Brazilian Journal of Medical and Biological Research, 2007
A method for the screening of tetanus and diphtheria antibodies in serum using anatoxin (inactivated toxin) instead of toxin was developed as an alternative to the in vivo toxin neutralization assay based on the toxin-binding inhibition test (TOBI test).

Toxin-Antitoxin Flocculation in Tetanus

Experimental Biology and Medicine, 1936
While the flocculation-test with diphtheria-toxin and antitoxin has given fairly good results,1, 2 the method has been found unreliable when applied to toxins and respective antitoxins of tetanus,3, 4, 5 botulinus,6, 7 staphylococcus,8 and Streptococcus scarlatinœ.9, 10Bronfenbrenner and Reichert6 found that antitoxin obtained by immunizing animals ...
