Marine aerobic biofilm as biocathode catalyst [PDF]

open access: yes, 2010
Stainless steel electrodes were immersed in open seawater and polarized for some days at − 200 mV vs. Ag/AgCl. The current increase indicated the formation of biofilms that catalysed the electrochemical reduction of oxygen.

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 ...

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.

Mycobacterium biofilms

open access: yesBiofilm, 2023
The genus Mycobacterium includes some of the deadliest pathogens of History (Mycobacterium tuberculosis, Mycobacterium leprae), but most of the species within the genus are environmental microorganisms. Because some of these nontuberculous mycobacteria (NTM) species can be human pathogens, the study of these mycobacterial biofilms has increased during ...

Biofilm dispersion [PDF]

open access: yesNature Reviews Microbiology, 2020
The formation of microbial biofilms enables single planktonic cells to assume a multicellular mode of growth. During dispersion, the final step of the biofilm life cycle, single cells egress from the biofilm to resume a planktonic lifestyle. As the planktonic state is considered to be more vulnerable to antimicrobial agents and immune responses ...

Biofilms Formed by Gram-Negative Bacteria Undergo Increased Lipid A Palmitoylation, Enhancing In Vivo Survival

open access: yesmBio, 2014
Bacterial biofilm communities are associated with profound physiological changes that lead to novel properties compared to the properties of individual (planktonic) bacteria.

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 ...

Bacteria-Infected Artificial Urine Characterization Based on a Combined Approach Using an Electronic Tongue Complemented with 1H-NMR and Flow Cytometry

open access: yesBiosensors, 2023
The prevailing form of bacterial infection is within the urinary tract, encompassing a wide array of bacteria that harness the urinary metabolome for their growth.

Staphylococcal Biofilms [PDF]

open access: yesMicrobiology Spectrum, 2008
ABSTRACTStaphylococci, with the leading speciesStaphylococcus aureusandStaphylococcus epidermidis, are the most frequent causes of infections on indwelling medical devices. The biofilm phenotype that those bacteria adopt during device-associated infection facilitates increased resistance to antibiotics and host immune defenses. This review presents and

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.
