Role of the flagellar hook in the structural development and antibiotic tolerance of Pseudomonas aeruginosa biofilms

open access: yesThe ISME Journal, 2021
Pseudomonas aeruginosa biofilms exhibit an intrinsic resistance to antibiotics and constitute a considerable clinical threat. In cystic fibrosis, a common feature of biofilms formed by P. aeruginosa in the airway is the occurrence of mutants deficient in

Robustness analysis of culturing perturbations on Escherichia coli colony biofilm beta-lactam and aminoglycoside antibiotic tolerance

open access: yesBMC Microbiology, 2010
Background Biofilms are ubiquitous. For instance, the majority of medical infections are thought to involve biofilms. However even after decades of investigation, the in vivo efficacy of many antimicrobial strategies is still debated suggesting there is ...

Proteolytic Queues at ClpXP Increase Antibiotic Tolerance [PDF]

open access: yesACS Synthetic Biology, 2019
Abstract Antibiotic tolerance is a widespread phenomenon that renders antibiotic treatments less effective and facilitates antibiotic resistance. Here we explore the role of proteases in antibiotic tolerance, short-term population survival of antibiotics, using queueing theory (i.e.

Human serum triggers antibiotic tolerance in Staphylococcus aureus

open access: yesNature Communications, 2021
Staphylococcus aureus frequently causes infections that are challenging to treat, leading to high rates of persistent and relapsing infection. Here, to understand how the host environment influences treatment outcomes, we study the impact of human serum ...

Antibiotic Tolerance and Treatment Outcomes in Cystic Fibrosis Methicillin-Resistant Staphylococcus aureus Infections

open access: yesMicrobiology spectrum, 2022
Chronic MRSA infections remain challenging to treat in patients with cystic fibrosis (CF). The ability of the bacterial population to survive high concentrations of bactericidal antibiotics, including vancomycin, despite lacking resistance is considered ...

Does diagnostic uncertainty increase antibiotic prescribing in primary care?

open access: yesnpj Primary Care Respiratory Medicine, 2021
This study aimed to determine the association between factors relevant to diagnostic uncertainty and physicians’ antibiotic-prescribing behaviour in primary care.

Comparative proteomic investigation of multiple methicillin-resistant Staphylococcus aureus strains generated through adaptive laboratory evolution

open access: yesiScience, 2021
Summary: Recent discoveries indicate that tolerance and resistance could rapidly evolve in bacterial populations under intermittent antibiotic treatment. In the present study, we applied antibiotic combinations in laboratory experiments to generate novel

PurN Is Involved in Antibiotic Tolerance and Virulence in Staphylococcus aureus

open access: yesAntibiotics, 2022
Staphylococcus aureus can cause chronic infections which are closely related to persister formation. Purine metabolism is involved in S. aureus persister formation, and purN, encoding phosphoribosylglycinamide formyltransferase, is an important gene in ...

The Sulfide-Responsive SqrR/BigR Homologous Regulator YgaV of Escherichia coli Controls Expression of Anaerobic Respiratory Genes and Antibiotic Tolerance

open access: yesAntioxidants, 2022
Compositions and activities of bacterial flora in the gastrointestinal tract significantly influence the metabolism, health, and disease of host humans and animals.

Genetic Determinants of Intrinsic Antibiotic Tolerance in Mycobacterium avium

open access: yesMicrobiology 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.
