Modulating the evolutionary trajectory of tolerance using antibiotics with different metabolic dependencies

Nature Communications, 2022
Antibiotic tolerance, or the ability of bacteria to survive antibiotic treatment in the absence of genetic resistance, often involves a low metabolic state. Here, Zheng et al. show that tolerance does not readily evolve against antibiotics whose efficacy

Genetic Determinants of Intrinsic Antibiotic Tolerance in Mycobacterium avium

Microbiology Spectrum, 2021
The Mycobacterium avium complex (MAC) is one of the most prevalent causes of nontuberculous mycobacteria pulmonary infection in the United States, and yet it remains understudied.

Antimicrobial Activity of the Quinoline Derivative HT61 against Staphylococcus aureus Biofilms. [PDF]

, 2020
Staphylococcus aureus biofilms are a significant problem in health care settings, partly due to the presence of a nondividing, antibiotic-tolerant subpopulation. Here we evaluated treatment of S.

Collective antibiotic tolerance: mechanisms, dynamics and intervention [PDF]

Nature Chemical Biology, 2015
Bacteria have developed resistance against every antibiotic at a rate that is alarming considering the timescale at which new antibiotics are developed. Thus, there is a critical need to use antibiotics more effectively, extend the shelf life of existing antibiotics and minimize their side effects.

A Dietary Source of High Level of Fluoroquinolone Tolerance in mcr-Carrying Gram-Negative Bacteria

Research, 2023
The emergence of antibiotic tolerance, characterized by the prolonged survival of bacteria following antibiotic exposure, in natural bacterial populations, especially in pathogens carrying antibiotic resistance genes, has been an increasing threat to ...

Inflammatory cytokines and biofilm production sustain Staphylococcus aureus outgrowth and persistence: A pivotal interplay in the pathogenesis of Atopic Dermatitis [PDF]

, 2018
Individuals with Atopic dermatitis (AD) are highly susceptible to Staphylococcus aureus colonization. However, the mechanisms driving this process as well as the impact of S. aureus in AD pathogenesis are still incompletely understood.

Dynamic energy budget approach to evaluate antibiotic effects on biofilms [PDF]

, 2017
Quantifying the action of antibiotics on biofilms is essential to devise therapies against chronic infections. Biofilms are bacterial communities attached to moist surfaces, sheltered from external aggressions by a polymeric matrix.

Antibiotic tolerance among clinical isolates of bacteria [PDF]

Antimicrobial Agents and Chemotherapy, 1986
One of the unique features of p-lactam antibiotics and other cell-wall inhibitors like vancomycin and bacitracin is that they can rapidly kill and in many cases lyse susceptible bacteria. Many other types of antibacterial agents (e.g., trimethoprim or chloramphenicol) are primarily bacteriostatic: they inhibit multiplication but do not cause an ...

Interplay between circadian and other transcription factors—Implications for cycling transcriptome reprogramming

FEBS Letters, EarlyView.
This perspective highlights emerging insights into how the circadian transcription factor CLOCK:BMAL1 regulates chromatin architecture, cooperates with other transcription factors, and coordinates enhancer dynamics. We propose an updated framework for how circadian transcription factors operate within dynamic and multifactorial chromatin landscapes ...

Persisters show heritable phenotype and generate bacterial heterogeneity and noise in protein expression [PDF]

, 2009
Persisters are a small subpopulation of bacteria that survive a lethal concentration of antibiotic without antibiotic resistance genes. Isolation of persisters from normally dividing population is considered difficult due to their slow growth, low ...
