Almost a third of our lives are spent sleeping. Necessary for the body to function properly, sleep should not be neglected. We now know that reducing the amount or quality of sleep has an impact on several functions. But did you know that going to bed at irregular hours also has an impact on the intestinal microbiota? At least, that's what a recently published British study suggests. Social jetlag: a shifted sleep pattern Sleep can be altered by several factors, whether associated with lifestyle (screens, night work, etc.) or the environment (lights, etc.). Research has shown that it disruption can have [...]

Researchers have brought together all the latest scientific advances on Faecalibacterium in a recently published review.   What are new-generation probiotics? According to the WHO, probiotics are live microorganisms which when administered in adequate amounts confer a health benefit on the host. Lactic acid bacteria are their main representatives, most of which are derived from fermented food products. Next generation probiotics are bacteria isolated from the human microbiome. Faecalibacterium is a bacterial genus belonging to this new category of probiotics. It is part of our commensal intestinal microbiota.   Presentation of Faecalibacterium This is a bacterial genus that has attracted growing [...]

A recent clinical trial provides new data on the microbiota of the penis. It reveals that bacteria in the male urethra come from two distinct sources, one of which is specific to men who have vaginal sex. The urethra is not spared, and like many organs, it is colonised by micro-organisms. However, it is possible to distinguish not one, but two microbiota within the penis. In a study published on 21 March 2023 in Cell Reports Medicine on 110 men, the results reveal the presence of bacteria in the male urethra from two different sources. These two microbiotas, named in the [...]

What are the effects of dysbiosis of the gut microbiota in humans ? Gut microbiota is implicated in the right functioning of many organs, such as lungs, kidneys, liver, heart and brain. However, any disruption to the microbiota homeostasis, called dysbiosis, results in the malfunctioning of these affected organs, and the progression of many related diseases.
