An optimised protocol for detection of SARS-CoV-2 in stool

BMC Microbiology, 2021
Background SARS-CoV-2 has been detected in stool samples of COVID-19 patients, with potential implications for faecal-oral transmission. Compared to nasopharyngeal swab samples, the complexity of the stool matrix poses a challenge in the detection of the

The Pregnancy and EARly Life study (PEARL) - a longitudinal study to understand how gut microbes contribute to maintaining health during pregnancy and early life

BMC Pediatrics, 2021
Background The early life period represents the first step in establishing a beneficial microbial ecosystem, which in turn affects both short and longer-term health.

LotuS2: an ultrafast and highly accurate tool for amplicon sequencing analysis

Microbiome, 2022
Background Amplicon sequencing is an established and cost-efficient method for profiling microbiomes. However, many available tools to process this data require both bioinformatics skills and high computational power to process big datasets. Furthermore,

Fecal microbiota transfer between young and aged mice reverses hallmarks of the aging gut, eye, and brain

Microbiome, 2022
Background Altered intestinal microbiota composition in later life is associated with inflammaging, declining tissue function, and increased susceptibility to age-associated chronic diseases, including neurodegenerative dementias.

Absence of Bacteria Permits Fungal Gut-To-Brain Translocation and Invasion in Germfree Mice but Ageing Alone Does Not Drive Pathobiont Expansion in Conventionally Raised Mice

Frontiers in Aging Neuroscience, 2022
Age-associated changes in the structure of the intestinal microbiome and in its interaction with the brain via the gut-brain axis are increasingly being implicated in neurological and neurodegenerative diseases.

Extracellular vesicles produced by the human gut commensal bacterium Bacteroides thetaiotaomicron elicit anti-inflammatory responses from innate immune cells

Frontiers in Microbiology, 2022
Bacterial extracellular vesicles (BEVs) produced by gut commensal bacteria have been proposed to play an important role in maintaining host homeostasis via interactions with the immune system.

Panakeia - a universal tool for bacterial pangenome analysis

BMC Genomics, 2022
Background Development of new pan-genome analysis tools is important, as the pangenome of a microbial species has become an important method to define the diversity of a selected taxon, most commonly a species, in the last years.

Global genomic pathogen surveillance to inform vaccine strategies: a decade-long expedition in pneumococcal genomics

Genome Medicine, 2021
Vaccines are powerful agents in infectious disease prevention but often designed to protect against some strains that are most likely to spread and cause diseases.

Role of mucin glycosylation in the gut microbiota-brain axis of core 3 O-glycan deficient mice

Scientific Reports, 2023
Alterations in intestinal mucin glycosylation have been associated with increased intestinal permeability and sensitivity to inflammation and infection. Here, we used mice lacking core 3-derived O-glycans (C3GnT−/−) to investigate the effect of impaired ...

Polyphosphate application influences morpho-physiological root traits involved in P acquisition and durum wheat growth performance

BMC Plant Biology, 2022
Background Among phosphate (P) fertilizers, polyphosphates (PolyPs) have shown promising results in terms of crop yield and plant P nutrition. However, compared to conventional P inputs, very little is known on the impact of PolyPs fertilizers on below ...
