Metagenomics analysis of bacterial structure communities within natural biofilm [PDF]

Heliyon, 2019
Résumé Les profils bactériens du biofilm domestique naturel n'ont pas été largement étudiés. La majorité de ces lignées bactériennes ne sont pas cultivables. Ainsi, cette étude vise (i) à énumérer certaines lignées bactériennes potentielles en utilisant une méthode basée sur la culture dans des échantillons de biofilm et confirmée en utilisant Biolog ...

Architectural differentiation reflects bacterial community structure in stream biofilms [PDF]

The ISME Journal, 2009
Abstract Laboratory studies have documented the extensive architectural differentiation of biofilms into complex structures, including filamentous streamers generated by turbulent flow. Still, it remains elusive whether this spatial organization of natural biofilms is reflected in the community structure.

Bacterial and archaeal community structures in perennial cave ice [PDF]

Scientific Reports, 2018
AbstractIce entrenched microcosm represents a vast reservoir of novel species and a proxy for past climate reconstitution. Among glacial ecosystems, ice caves represent one of the scarcely investigated frozen habitats. To characterize the microbial diversity of perennial ice from karst ecosystems, Roche 454 sequencing of 16S rRNA gene amplicons from ...

Bacterial epibiont communities of panmictic Antarctic krill are spatially structured [PDF]

Molecular Ecology, 2021
AbstractAntarctic krill (Euphausia superba) are amongst the most abundant animals on Earth, with a circumpolar distribution in the Southern Ocean. Genetic and genomic studies have failed to detect any population structure for the species, suggesting a single panmictic population.

Deterministic processes structure bacterial genetic communities across an urban landscape [PDF]

Nature Communications, 2019
AbstractLand-use change is predicted to act as a driver of zoonotic disease emergence through human exposure to novel microbial diversity, but evidence for the effects of environmental change on microbial communities in vertebrates is lacking. We sample wild birds at 99 wildlife-livestock-human interfaces across Nairobi, Kenya, and use whole genome ...

Acidification increases abundances of Vibrionales and Planctomycetia associated to a seaweed-grazer system: potential consequences for disease and prey digestion efficiency [PDF]

, 2018
Ocean acidification significantly affects marine organisms in several ways, with complex interactions. Seaweeds might benefit from rising CO2 through increased photosynthesis and carbon acquisition, with subsequent higher growth rates.

Temporal and Spatial Impact of Human Cadaver Decomposition on Soil Bacterial and Arthropod Community Structure and Function [PDF]

, 2018
As vertebrate carrion decomposes, there is a release of nutrient-rich fluids into theunderlying soil, which can impact associated biological community structure andfunction. How these changes alter soil biogeochemical cycles is relatively unknown and may

Impact of Experimental Hookworm Infection on the Human Gut Microbiota [PDF]

, 2014
The interactions between gastrointestinal parasitic helminths and commensal bacteria are likely to play a pivotal role in the establishment of host-parasite cross-talk, ultimately shaping the development of the intestinal immune system.

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.

Soil Microbial Community Response to Nitrogen Application on a Swamp Meadow in the Arid Region of Central Asia

Frontiers in Microbiology, 2022
Although a large number of studies have reported the importance of microbial communities in terrestrial ecosystems and their response to nitrogen (N) application, it is not clear in arid alpine wetlands, and the mechanisms involved need to be clarified ...
