Widespread fungal-bacterial competition for magnesium lowers bacterial susceptibility to polymyxin antibiotics. [PDF]

PLoS Biol
Fungi and bacteria coexist in many polymicrobial communities, yet the molecular basis of their interactions remains poorly understood. Here, we show that the fungus Candida albicans sequesters essential magnesium ions from the bacterium Pseudomonas aeruginosa. To counteract fungal Mg2+ sequestration, P.

The idiosyncrasy of spatial structure in bacterial competition. [PDF]

BMC Res Notes, 2015
The spatial structure of a habitat can have a strong impact on community dynamics. Different experimental approaches exist to explore the effect of spatial structure on bacterial communities. To investigate the effect of 'space', a single implementation of spatial structure is often contrasted to bacterial community dynamics in well-mixed cultures ...

Competitive effects in bacterial mRNA decay

Journal of Theoretical Biology, 2020
In living organisms, the same enzyme catalyses the degradation of thousands of different mRNAs, but the possible influence of competing substrates has been largely ignored so far. We develop a simple mechanistic model of the coupled degradation of all cell mRNAs using the total quasi-steady-state approximation of the Michaelis-Menten framework ...

Competitive adherence as a mechanism of bacterial interference [PDF]

Canadian Journal of Microbiology, 1983
To determine whether competition among bacteria for specific attachment sites on host cells can explain bacterial interference, Staphylococcus aureus strain 502A was tested in turn against two different nasal coryneforms, a strain of Pseudomonas aeruginosa, and a virulent strain of S. aureus, all in the presence of nasal mucosal cells.

Characterization of the Achromobacter xylosoxidans Type VI Secretion System and Its Implication in Cystic Fibrosis

Frontiers in Cellular and Infection Microbiology, 2022
Bacteria of the genus Achromobacter are environmental germs, with an unknown reservoir. It can become opportunistic pathogens in immunocompromised patients, causing bacteremia, meningitis, pneumonia, or peritonitis.

Neisseria mucosa Does Not Inhibit the Growth of Neisseria gonorrhoeae

Sci, 2022
Antibiotic-sparing treatments are required to prevent the further emergence of antimicrobial resistance in Neisseria gonorrhoeae. Commensal Neisseria species have previously been found to inhibit the growth of pathogenic Neisseria species. For example, a

Stability of multispecies bacterial communities: Signaling networks may stabilize microbiomes [PDF]

, 2013
Multispecies bacterial communities can be remarkably stable and resilient even though they consist of cells and species that compete for environmental resources.

Putative Antimicrobial Peptides Within Bacterial Proteomes Affect Bacterial Predominance: A Network Analysis Perspective

Frontiers in Microbiology, 2021
The predominance of bacterial taxa in the gut, was examined in view of the putative antimicrobial peptide sequences (AMPs) within their proteomes.

The coevolution of toxin and antitoxin genes drives the dynamics of bacterial addiction complexes and intragenomic conflict [PDF]

, 2012
Bacterial genomes commonly contain 'addiction' gene complexes that code for both a toxin and a corresponding antitoxin. As long as both genes are expressed, cells carrying the complex can remain healthy.

Cooperation, competition and antibiotic resistance in bacterial colonies [PDF]

The ISME Journal, 2018
Abstract Bacteria commonly live in dense and genetically diverse communities associated with surfaces. In these communities, competition for resources and space is intense, and yet we understand little of how this affects the spread of antibiotic-resistant strains.
