Diversity at its best: bacterial taxis [PDF]

Environmental Microbiology, 2010
Summary Bacterial taxis is one of the most investigated signal transduction mechanisms. Studies of taxis have primarily used Escherichia coli and Salmonella as model organism.

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

FEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

Adenylylation of Gyrase and Topo IV by FicT Toxins Disrupts Bacterial DNA Topology [PDF]

, 2015
Toxin-antitoxin (TA) modules are ubiquitous molecular switches controlling bacterial growth via the release of toxins that inhibit cell proliferation.

The human gut microbiome across the life course

FEBS Letters, EarlyView.
Despite significant individual variation and continuous change throughout life, the human gut microbiome follows some life stage‐specific trends. This article provides a brief overview of how gut microbiome composition shifts across different phases of life. Created in BioRender. Özkurt, E. (2026) https://BioRender.com/8q4nrnc.

Diversity of Xenorhabdus and Photorhabdus spp. and their symbiotic entomopathogenic nematodes from Thailand [PDF]

, 2012
Xenorhabdus and Photorhabdus spp. are bacterial symbionts of entomopathogenic nematodes (EPNs). In this study, we isolated and characterized Xenorhabdus and Photorhabdus spp.

Manure amendment and the rhizosphere of Amaranthus hybridus soil bacterial communities in a semi-arid irrigated agroecosystem

Ecosistemas y Recursos Agropecuarios
Soil biodiversity is fundamental to nutrient cycling and ecosystem functioning in agroecosystems, yet the combined effects of organic amendments and weed rhizospheres on soil bacterial communities remain insufficiently explored in semi-arid irrigated ...

Bacterial diversity is positively correlated with soil heterogeneity

Ecosphere, 2018
Plant and animal diversity generally increases with increasing environmental heterogeneity. Here, we test whether this relationship also holds for bacterial communities in soil. Specifically, we investigate whether invasive annual grasslands have reduced

Paenibacillus sp. Strain OL15 Immobilized in Agar as a Potential Bioremediator for Waste Lubricating Oil-Contaminated Soils and Insights into Soil Bacterial Communities Affected by Inoculations of the Strain and Environmental Factors

Biology, 2022
Waste lubricating oil is a widespread common soil pollutant. In this study, the waste lubricating oil degraders were isolated from the oil-contaminated soil.

Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

FEBS Letters, EarlyView.
We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...

Insights into the bacterial symbiont diversity in spiders [PDF]

Ecology and Evolution, 2018
AbstractMost spiders are natural enemies of pests, and it is beneficial for the biological control of pests to learn the relationships between symbionts and their spider hosts. Research on the bacterial communities of insects has been conducted recently, but only a few studies have addressed the bacterial communities of spiders.
