Shooting yourself in the foot: How immune cells induce antibiotic tolerance in microbial pathogens.
PLoS Pathogens, 2021 Antibiotic treatment failure of infection is common and frequently occurs in the absence of genetically encoded antibiotic resistance mechanisms. In such scenarios, the ability of bacteria to enter a phenotypic state that renders them tolerant to the ...

In vitro activity of ceftazidime, ciprofloxacin, meropenem, minocycline, tobramycin and trimethoprim/sulfamethoxazole against planktonic and sessile Burkholderia cepacia complex bacteria [PDF]
, 2009 Objectives: The goal of the present study was to obtain a comprehensive overview of the bacteriostatic and bactericidal effects of six commonly used antibiotics on planktonic as well as on sessile Burkholderia cepacia complex cells.

Molecular analysis of antibiotic tolerance in pneumococci
International Journal of Medical Microbiology, 2002 Widespread pneumococcal resistance and the emergence of tolerance underscores the need to develop new antimicrobials. Uncovering the mechanisms of autolysin activation could yield not only new antibacterial targets but also ways to eradicate a pool of bacteria facilitating the spread of resistance.

FEBS Open Bio, EarlyView.5‐Aminolevulinic acid combined with ferric ammonium citrate (5‐ALA/FAC) stimulates dermal papilla cell activity and promotes hair follicle growth. The treatment enhances ERK and AKT signaling, increases hair‐inductive gene expression, and restores dermal papilla function suppressed by dihydrotestosterone and oxidative stress, resulting in enhanced hair

Advanced Engineering Materials, EarlyView.This study investigates innovative thermoreversible hydrogels derived from S53P4 bioactive glass extracts to aid in the healing of infected diabetic foot wounds. These injectable gels, which gel at body temperature, release beneficial ions and remain stable over time.

Hydrogen Sulfide Sensitizes Acinetobacter baumannii to Killing by Antibiotics
Frontiers in Microbiology, 2020 The production of endogenous hydrogen sulfide (H2S) has been shown to confer antibiotic tolerance in all bacteria studied to date. Therefore, this mediator has been speculated to be a universal defense mechanism against antibiotics in bacteria.

Examination of the effect of reduction of probiotic species Lactobacillus due to broad spectrum antibiotic treatment on oral tolerance [PDF]
, 2009 Antibiotic usage is on the rise in industrialized countries and as a result the prevalence of autoimmune and atopic diseases has risen. The use of antibiotics is connected to a depletion of the microflora located within the gastrointestinal tract.

Staphylococcus aureus Persisters Tolerant to Bactericidal Antibiotics [PDF]
Microbial Physiology, 2012 Bacterial persister cells are non- or slow-growing reversible phenotypic variants of the wild type, tolerant to bactericidal antibiotics. We analyzed here Staphylococcus aureus persister levels by monitoring colony-forming unit counts of planktonically grown cells treated with six different antimicrobials over time.

Advanced Engineering Materials, EarlyView.Selenium was incorporated into a sol–gel‐derived bioactive glass to enable sustained therapeutic ion release. The selenium‐containing glass preserved bioactivity while selectively inducing cytotoxicity in osteosarcoma cells and maintaining osteoblastic viability.
