Stay or Go: Sulfolobales Biofilm Dispersal Is Dependent on a Bifunctional VapB Antitoxin
mBio, 2023 A type II VapB14 antitoxin regulates biofilm dispersal in the archaeal thermoacidophile Sulfolobus acidocaldarius through traditional toxin neutralization but also through noncanonical transcriptional regulation.

Induced DNA bending by unique dimerization of HigA antitoxin
IUCrJ, 2020 The bacterial toxin–antitoxin (TA) system regulates cell growth under various environmental stresses. Mycobacterium tuberculosis, the causative pathogen of tuberculosis (TB), has three HigBA type II TA systems with reverse gene organization, consisting ...

Clinical cases of atypical and severe botulism
Zaporožskij Medicinskij Žurnal, 2020 The aim of the work was to present two clinical cases of botulism: the atypical course and the severe course with late administration of heptavalent botulinum antitoxin, which still had a significant positive clinical effect and contributed to a faster ...

Structure, Evolution, and Functions of Bacterial Type III Toxin-Antitoxin Systems. [PDF]
, 2016 Toxin-antitoxin (TA) systems are small genetic modules that encode a toxin (that targets an essential cellular process) and an antitoxin that neutralises or suppresses the deleterious effect of the toxin.

Humoral Response of Buffaloes to a Recombinant Vaccine against Botulism Serotypes C and D
Toxins, 2017 Botulism is a fatal intoxication caused by botulinum neurotoxins (BoNTs), which are mainly produced by Clostridium botulinum and characterized by flaccid paralysis.

Immunological Characterization and Neutralizing Ability of Monoclonal Antibodies Directed Against Botulinum Neurotoxin Type H. [PDF]
, 2016 BackgroundOnly Clostridium botulinum strain IBCA10-7060 produces the recently described novel botulinum neurotoxin type H (BoNT/H). BoNT/H (N-terminal two-thirds most homologous to BoNT/F and C-terminal one-third most homologous to BoNT/A) requires ...

YoeB toxin is activated during thermal stress. [PDF]
, 2015 Type II toxin-antitoxin (TA) modules are thought to mediate stress-responses by temporarily suppressing protein synthesis while cells redirect transcription to adapt to environmental change.

Toxin-antitoxins and bacterial virulence.
FEMS Microbiology Reviews, 2016 Bacterial virulence relies on a delicate balance of signals interchanged between the invading microbe and the host. This communication has been extensively perceived as a battle involving harmful molecules produced by the pathogen and host defenses.
