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

open access: yesPLoS 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 IMMUNIZATION AGAINST DIPHTHERIA [PDF]

open access: yesJAMA: The Journal of the American Medical Association, 1922
The development of antitoxin in the bodies of animals injected with diphtheria toxin is one of the best established of facts. Since von Behring and Roux announced the results of their investigations, large numbers of horses have been injected with toxin and have developed abundant antitoxin.

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

open access: yesBrazilian 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).

The role of efflux and physiological adaptation in biofilm tolerance and resistance

open access: yes, 2016
Microbial biofilms demonstrate a decreased susceptibility to antimicrobial agents. Various mechanisms have been proposed to be involved in this recalcitrance. We focus on two of these factors.

Toxin-Antitoxin Flocculation in Tetanus

open access: yesExperimental 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 ...

Druggability of bacterial toxins-antitoxins [PDF]

open access: yes, 2015
53 p.-8 fig.-3 tab.Type II (proteic) toxin-antitoxin (TA) operons are widely spread in bacteria and archaea. They are organized as operons in which, usually, the antitoxin gene precedes the cognate toxin gene.

Novel Single-Cell Method for Studying Toxin-Antitoxin Systems [PDF]

open access: yes, 2016
细菌的抗药性危害日益严重,毒素-抗毒素(TA)系统在细菌内的异质性表达是多药耐受性存留细胞形成的重要原因。阐明致病菌中毒素-抗毒素系统的作用机理和生理功能对研发防控致病菌的新策略和疾病诊断治疗等具有重要意义。目前,对TA系统的研究主要集中在基因水平或转录水平,而传统基于蛋白质水平的检测方法,如WesternBlot等都是对大量细菌裂解液中的毒素抗毒素蛋白进行检测,是大量细菌内毒素抗毒素蛋白表现的集权平均。对单细菌水平的毒素-抗毒素蛋白进行快速逐一分析可揭示因集权平均而被掩盖的个体差异 ...
