Functional validation of putative toxin-antitoxin genes from the Gram-positive pathogen Streptococcus pneumoniae: phd-doc is the fourth bona-fide operon.

Frontiers in microbiology

Chan WT, Yeo CC, Sadowy E, Espinosa M.
PMID: 25538695
Front Microbiol. 2014 Dec 05;5:677. doi: 10.3389/fmicb.2014.00677. eCollection 2014.

Bacterial toxin-antitoxin (TAs) loci usually consist of two genes organized as an operon, where their products are bound together and inert under normal conditions. However, under stressful circumstances the antitoxin, which is more labile, will be degraded more rapidly,...

FURTHER STUDIES ON THE TITRATION AND NEUTRALIZATION OF THE WESTERN STRAIN OF EQUINE ENCEPHALOMYELITIS VIRUS IN TISSUE CULTURE.

The Journal of experimental medicine

Huang CH.
PMID: 19871313
J Exp Med. 1943 Aug 01;78(2):111-26. doi: 10.1084/jem.78.2.111.

1. Titration and neutralization of the Western strain of equine encephalomyelitis virus can be carried out in vitro by means of tissue culture. 2. The in vitro titration test as presented is a more sensitive method than animal inoculation....

EXPERIMENTS ON THE PRODUCTION OF SPECIFIC ANTISERA FOR INFECTIONS OF UNKNOWN CAUSE : I. TYPE EXPERIMENTS WITH KNOWN ANTIGENS-A BACTERIAL HEMOTOXIN (MEGATHERIOLYSIN), THE PNEUMOCOCCUS, AND POLIOMYELITIC VIRUS.

The Journal of experimental medicine

Rous P, Robertson OH, Oliver J.
PMID: 19868319
J Exp Med. 1919 Feb 28;29(3):283-304. doi: 10.1084/jem.29.3.283.

Attempts to produce antisera in animals to combat specific infections are usually deferred until the cause of the infection has been isolated and grown in pure culture to furnish antigen. It has seemed to us that the fulfillment of...

The Variety in the Common Theme of Translation Inhibition by Type II Toxin-Antitoxin Systems.

Front Genet. 2020 Apr 17;11:262. doi: 10.3389/fgene.2020.00262. eCollection 2020.

Type II Toxin-antitoxin (TA) modules are bacterial operons that encode a toxic protein and its antidote, which form a self-regulating genetic system. Antitoxins put a halter on toxins in many ways that distinguish different types of TA modules. In...

Immunodiffusion Detection of Clostridium botulinum Colonies.

Journal of food protection

Lilly T, Kautter DA, Lynt RK, Solomon HM.

J Food Prot. 1984 Nov;47(11):868-870. doi: 10.4315/0362-028X-47.11.868.

Toxic colonies of Clostridium botulinum types A, B, E and F were detected by precipitating toxin around the colonies on agar containing antitoxin. Incorporating antitoxin in a gel diffusion agar overlay after colonies had developed was unsatisfactory for detection...

Front Microbiol. 2016 Dec 21;7:2071. doi: 10.3389/fmicb.2016.02071. eCollection 2016.

Toxin-antitoxin (TA) systems, which consist of an intracellular toxin and its antidote (antitoxin), are encoded by ubiquitous genetic modules in prokaryotes. Commonly, the activity of a toxin is inhibited by its antitoxin under normal growth conditions. However, antitoxins are...

Gulf War Illness (GWI) is defined by the Centers for Disease Control and Prevention (CDC) as a multi-symptom illness having at least one symptom from two of three factors, which include: fatigue, mood-cognition problems, and musculoskeletal disorders. The cluster...

Clostridioides difficile - phage relationship the RNA way.

Clostridioides difficile (formerly Clostridium difficile)-associated diarrhea is currently the most frequently occurring nosocomial diarrhea worldwide. During its infection cycle this pathogen needs to survive in phage-rich gut communities. Recent data strongly suggest that regulatory RNAs control gene expression in...

Toxin-antitoxin (TA) systems are small genetic elements composed of a noxious toxin and a counteracting cognate antitoxin. Although they are widespread in bacterial chromosomes and in mobile genetic elements, their cellular functions and activation mechanisms remain largely unknown. It...
