Microbial phenotypic heterogeneity and antibiotic tolerance
Current Opinion in Microbiology, 2007Phenotypic heterogeneity, defined as metastable variation in cellular parameters generated by epigenetic mechanisms, is crucial for the persistence of bacterial populations under fluctuating selective pressures. Diversity ensures that some individuals will survive a potentially lethal stress, such as an antibiotic, that would otherwise obliterate the ...

Current Opinion in Microbiology
Bacterial biofilms consist of large, self-formed aggregates where resident bacteria can exhibit very different physiological states and phenotypes. This heterogeneity of cell types is crucial for many structural and functional emergent properties of ...

Nanoparticles Promote Bacterial Antibiotic Tolerance via Inducing Hyperosmotic Stress Response.
Small, 2022With the rapid development of nanotechnology, nanoparticles (NPs) are widely used in all fields of life. Nowadays, NPs have shown extraordinary antimicrobial activities and become one of the most popular strategies to combat antibiotic resistance ...

Metal-containing landfills as a source of antibiotic tolerance
Environmental Monitoring and Assessment, 2023To unveil the potential effect of metal presence to antibiotic tolerance proliferation, four sites of surface landfills containing tailings from metal processing in Slovakia (Hnúšťa, Hodruša, Košice) and Poland (Tarnowskie Góry) were investigated. Tolerance and multitolerance to selected metals (Cu, Ni, Pb, Fe, Zn, Cd) and antibiotics (ampicillin ...

Antibiotic Tolerance of Staphylococcus epidermidis
Scandinavian Journal of Infectious Diseases, 1985The phenomenon of antibiotic tolerance was studied in 50 strains of Staphylococcus epidermidis isolated from blood cultures. The antibiotics used for study were methicillin, nafcillin, oxacillin, cephalothin, cefazolin and vancomycin. The MICs and MBCs were determined in Mueller Hinton Broth (MHB) and Brain Heart Infusion broth (BHI) after incubation ...

Nonmultiplying Bacteria are Profoundly Tolerant to Antibiotics
2012Bacteria survive treatments with antimicrobial agents; they achieve this in two ways. Firstly, bacteria quickly become tolerant to these agents. This tolerance is temporary, reversible, and associated with slowing of the multiplication rate. Secondly, bacteria can undergo genetic mutations leading to permanent clonal resistance to antimicrobial agents.

Safety and tolerability of inhaled antibiotics in patients with bronchiectasis
Pulmonary Pharmacology & Therapeutics, 2022Bronchiectasis is typically treated with inhaled antibiotics in clinical practice. However, there is a striking lack of standardised procedures for the preparation of noncommercial solutions. We used biochemical parameters to analyse the safety and tolerability of inhaled antibiotics in patients with bronchiectasis, and determined potential ...

Antibiotic Tolerance in Producer Organisms
1979Publisher Summary Antibiotics are found predominantly in the culture medium and not within the cells. This suggests that excretion is built into the biosynthetic process and, on present evidences, it is predicted that a mechanism to discourage reentry of the metabolite is an essential component in a majority of protective systems.
