A case of infant botulism in a 4-month-old baby [PDF]

open access: yes, 2016
This case-report highlights: i) the difficulty of IB diagnosis as it is a rare syndrome with subclinical onset, ii) the need for an accurate training for physicians involved in IB management, iii) the efficacy and safety of TEqA in IB treatment, iv ...

Evolution of the SpoIISABC Toxin-Antitoxin-Antitoxin System in Bacilli [PDF]

open access: yesToxins, 2016
Programmed cell death in bacteria is generally associated with two-component toxin-antitoxin systems. The SpoIISABC system, originally identified in Bacillus subtilis, consists of three components: a SpoIISA toxin and the SpoIISB and SpoIISC antitoxins. SpoIISA is a membrane-bound protein, while SpoIISB and SpoIISC are small cytosolic antitoxins, which

The Cysteine Protease MaOC1, a Prokaryotic Caspase Homolog, Cleaves the Antitoxin of a Type II Toxin-Antitoxin System

open access: yesFrontiers in Microbiology, 2021
The bloom-forming cyanobacterium Microcystis aeruginosa is known for its global distribution and for the production of toxic compounds. In the genome of M.

The light chain but not the heavy chain of botulinum A toxin inhibits exocytosis from permeabilized adrenal chromaffin cells [PDF]

open access: yes, 1989
The heavy and light chains of botulinum A toxin were separated by anion exchange chromatography. Their intracellular actions were studied using bovine adrenal chromaffin cells permeabilized with streptolysin O.

Diverse genetic contexts of HicA toxin domains propose a role in anti-phage defense

open access: yesmBio
Toxin–antitoxin (TA) modules are prevalent in prokaryotic genomes, often in substantial numbers. For instance, the Mycobacterium tuberculosis genome alone harbors close to 100 TA modules, half of which belong to a singular type.

Complete Assembly of the Genome of an Acidovorax citrulli Strain Reveals a Naturally Occurring Plasmid in This Species [PDF]

open access: yes, 2019
Acidovorax citrulli is the causal agent of bacterial fruit blotch (BFB), a serious threat to cucurbit crop production worldwide. Based on genetic and phenotypic properties, A.

A MXene‐Based Nanothermal Knife Inhibits Aggresome‐Mediated Persister Formation for Preventing Dental Caries

open access: yesAdvanced Science, EarlyView.
Early childhood caries (ECC) involves cariogenic persisters that evade antimicrobial treatment. Persisters achieve this by downregulating heat shock proteins (HSPs) and formation of protein aggregates. Ti3C2 MXene‐based photothermal therapy (PTT) acts as a “nanothermal knife,” disrupting membranes, upregulating HSPs, inhibits aggregates, prevents ...

Role of Homologous Fc Fragment in the Potency and Efficacy of Anti‐Botulinum Antibody Preparations

open access: yesToxins, 2017
The only approved treatment for botulism relies on passive immunity which is mostly based on antibody preparations collected from hyper‐immune horses. The IgG Fc fragment is commonly removed from these heterologous preparations to reduce the incidence of

Molecular Characterization of SehB, a Type II Antitoxin of Salmonella enterica Serotype Typhimurium: Amino Acid Residues Involved in DNA-Binding, Homodimerization, Toxin Interaction, and Virulence

open access: yesFrontiers in Microbiology, 2020
Salmonella enterica serotype Typhimurium is a bacterium that causes gastroenteritis and diarrhea in humans. The genome of S. Typhimurium codes for diverse virulence factors, among which are the toxin-antitoxin (TA) systems.
