Small, EarlyView.Biomimetic nanocarriers based on liposomes and Myxobacteria outer‐membrane vesicles (OMVs) are effective antibiotic delivery systems. Hybrids have a higher drug loading and can target intracellular pathogens, while OMVs evade immune clearance. Biomimetic nanoantibiotics effectively eliminate the biofilms of Gram‐negative bacteria. Besides, Myxobacteria

Holling Type I versus Holling Type II functional responses in Gram-negative bacteria [PDF]
, 2018 We consider how the double-membrane structure of the cell envelope of Gram-negative bacteria affects its functional response, which is the mathematical relationship that expresses how the nutrient uptake flux depends on environmental conditions.

Chromosome‐scale genome assembly of the South American fruit fly, Anastrepha fraterculus sp.1
Insect Science, EarlyView.Anastrepha fraterculus sp. 1 is a major fruit fly pest in Argentina, currently controlled through chemical treatments and traps. This study aims to enhance the genomic understanding of this species to support the development of sterile insect technique as well as the use of innovative technologies.

The Role of the Hfq Protein in Bacterial Resistance to Antibiotics: A Narrative Review
MicroorganismsThe antibiotic resistance of pathogenic microorganisms is currently one of most major medical problems, causing a few million deaths every year worldwide due to untreatable bacterial infections.

Role of metal-dependent regulation of ESX-3 secretion in intracellular survival of Mycobacterium tuberculosis [PDF]
, 2016 More people die every year from Mycobacterium tuberculosis infection than from infection by any other bacterial pathogen. Type VII secretion systems (T7SS) are used by both environmental and pathogenic mycobacteria to secrete proteins across their ...

The FEBS Journal, EarlyView.Expression of the LEA‐K peptide in E. coli BL21 (DE3) improved bacterial viability under acidic stress (pH4), suggesting a protective function. RNA‐sequencing of LEA‐K‐expressing vs. non‐expressing cells revealed 283 differentially expressed genes (DEGs). In silico docking linked LEA‐K to two‐component systems (TCS) proteins (Rcs, BtsS/R, and EnvZ/OmpR)

The ribosome‐associated complex regulates cytosolic translation upon mitoprotein‐induced stress
The FEBS Journal, EarlyView.Defects in mitochondrial protein import trigger a stress response. The contribution of translation regulation to such a response is only partially understood. We demonstrate that the deletion of mitochondrial surface proteins (TOM70/TOM71) leads to defects in mitochondrial biogenesis and slow growth.

Membranes, 2020 Fluoroquinolones (FQs) are broad-spectrum antibiotics largely used in the clinical practice against Gram-negative and some Gram-positive bacteria. Nevertheless, bacteria have developed several antimicrobial resistance mechanisms against such class of ...

Silver resistance in Gram-negative bacteria: a dissection of endogenous and exogenous mechanisms [PDF]
, 2015 Objectives: To gain a more detailed understanding of endogenous (mutational) and exogenous (horizontally acquired) resistance to silver in Gram-negative pathogens, with an emphasis on clarifying the genetic bases for resistance.
