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.

Regulating Toxin-Antitoxin Expression: Controlled Detonation of Intracellular Molecular Timebombs

Toxins, 2014
Genes for toxin-antitoxin (TA) complexes are widely disseminated in bacteria, including in pathogenic and antibiotic resistant species. The toxins are liberated from association with the cognate antitoxins by certain physiological triggers to impair ...

Coupling immunity and programmed cell suicide in prokaryotes: Life-or-death choices [PDF]

, 2017
Host-pathogen arms race is a universal, central aspect of the evolution of life. Most organisms evolved several distinct yet interacting strategies of anti-pathogen defense including resistance to parasite invasion, innate and adaptive immunity, and ...

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).

Analysis of virus genomes from glacial environments reveals novel virus groups with unusual host interactions [PDF]

, 2015
Microbial communities in glacial ecosystems are diverse, active, and subjected to strong viral pressures and infection rates. In this study we analyse putative virus genomes assembled from three dsDNA viromes from cryoconite hole ecosystems of Svalbard ...
