Intermittent antibiotic treatment of bacterial biofilms favors the rapid evolution of resistance

open access: yesCommunications Biology, 2023
Mutations in sbmA and fusA are rapidly selected in biofilm but not planktonic E. coli when exposed to intermittent amikacin antibiotic treatment, which suggests that the biofilm environment favors rapid evolution of resistance.

Biofilms as Promoters of Bacterial Antibiotic Resistance and Tolerance

open access: yesAntibiotics, 2020
Multidrug resistant bacteria are a global threat for human and animal health. However, they are only part of the problem of antibiotic failure. Another bacterial strategy that contributes to their capacity to withstand antimicrobials is the formation of ...

Anti-diarrheal drug loperamide induces dysbiosis in zebrafish microbiota via bacterial inhibition

open access: yesMicrobiome, 2023
Background Perturbations of animal-associated microbiomes from chemical stress can affect host physiology and health. While dysbiosis induced by antibiotic treatments and disease is well known, chemical, nonantibiotic drugs have recently been shown to ...

A dissipative particle dynamics model of biofilm growth [PDF]

open access: yesPhys. Rev. E 83, 066702, 2011, 2018
A dissipative particle dynamics (DPD) model for the quantitative simulation of biofilm growth controlled by substrate (nutrient) consumption, advective and diffusive substrate transport, and hydrodynamic interactions with fluid flow (including fragmentation and reattachment) is described.

Visible spectroelectrochemical characterization of geobacter sulfurreducens biofilms on optically transparent indium tin oxide electrode [PDF]

open access: yes, 2011
We report visible spectroelectrochemical (SEC) characterization of cytochrome c552 (cyt c552) in viable Geobacter sulfurreducens biofilms on tin-doped indium oxide (ITO) electrodes poised at 0.24 V vs.. SHE. G.

Screening of Escherichia coli Species Biodiversity Reveals New Biofilm-Associated Antiadhesion Polysaccharides

open access: yesmBio, 2011
Bacterial biofilms often form multispecies communities in which complex but ill-understood competition and cooperation interactions occur. In light of the profound physiological modifications associated with this lifestyle, we hypothesized that the ...

Polymicrobial synergy stimulates Porphyromonas gingivalis survival and gingipain expression in a multi-species subgingival community

open access: yesBMC Oral Health, 2021
Background Dysbiosis in subgingival microbial communities, resulting from increased inflammatory transudate from the gingival tissues, is an important factor in initiation and development of periodontitis.

Host Soluble Factors Cause Changes in Staphylococcus epidermidis Antibiotic Susceptibility and Biofilm Formation Ability

open access: yesPathogens, 2023
Staphylococcus epidermidis is a major nosocomial pathogen with a remarkable ability to adhere to the surfaces of indwelling medical devices and form biofilms. Unlike other nosocomial pathogens, the interaction of S.
