Microbial communities are groups of microorganisms that share a common living space. The microbial populations that form the community can interact in different ways, for example as predators and prey or as symbionts.
Altering gut bacteria in male mice revealed that microorganisms are needed for normal sperm development and offspring health. Scientists discuss the implications in terms of understanding microbes, male fertility and pregnancy.
Two species of auxotrophic marine bacteria are shown to share precursors to synthesize the essential cofactor vitamin B12, and such ligand cross-feeding may be a common phenomenon in the ocean and other ecosystems.
The gut microbiota and microglia play critical roles in Alzheimer’s disease (AD). Here, the authors show that Bacteroides fragilis contributes to AD pathogenesis in mouse models by suppressing immune-mediated microglial clearance of amyloid beta.
Altering gut bacteria in male mice revealed that microorganisms are needed for normal sperm development and offspring health. Scientists discuss the implications in terms of understanding microbes, male fertility and pregnancy.
Unusual microbial communities in a person’s lower airways could influence the onset and progression of lung cancer and other conditions, and might point the way to therapies.
Multidisciplinary culture-dependent and -independent techniques elucidate the unique microbial nitrogen cycle in nutrient-poor coastal Antarctica soils and reveal the contribution of novel key microbes to their nitrogen budget.
This Genome Watch article highlights the recent use of large-scale monitoring of natural microbiomes to examine feedback between environmental change and microbial adaptation.
The clinical translation of therapeutics on the basis of human gut microorganisms is hampered by our limited knowledge of how microbes survive and adapt to fluctuating conditions in the gut. The systematic exploration of gut microbiome survival strategies and trade-offs will thus enable the design of more efficient microbiome-based interventions.
