What does the change in taxonomy of the genus Lactobacillus imply?

Laura_Exden2020-07-15T16:01:38+02:0026 June 2020|That's your concern, The Science|Comments Off on What does the change in taxonomy of the genus Lactobacillus imply?

After several years of work and discussion, the taxonomy of the genus Lactobacillus is modified. This change will have many economic, scientific and regulatory consequences. Why is the Lactobacillus taxonomy changing? What is taxonomy? This is the science that classifies, groups and names living organisms. Lactobacilli were first described in 1901 with Lactobacillus delbrueckii, an essential species for the yogurt production. Over time, thanks to new methods of genetic sequencing, more than 260 different species of Lactobacilli have been identified. The accepted normal diversity being exceeded, it is no longer possible to reasonably and coherently group these species because of the [...]

Future moms: your microbiota during pregnancy

Laura_Exden2020-06-11T10:09:11+02:0012 June 2020|The Science, Women|Comments Off on Future moms: your microbiota during pregnancy

It is a fact, pregnancy leads to major endocrine, metabolic and immunological changes. However, did you know that the bacteria you harbor will also be impacted, in intestine, vagina and placenta? Pregnancy impacts the intestinal microbiota… The intestinal microbiota changes throughout pregnancy: the bacterial diversity as well as the richness decrease between the 1st and the 3rd trimester. During the first trimester, the bacterial ecosystem is comparable to that of healthy non-pregnant women. A considerable change is observable from the 2nd trimester of pregnancy, and even more important in the last trimester. These differences in composition include loss of bacterial diversity [...]

Is the intestinal microbiota linked to muscle strength?

Laura_Exden2020-05-26T12:38:43+02:0017 April 2020|The Science|Comments Off on Is the intestinal microbiota linked to muscle strength?

Is the intestinal microbiota linked to muscle strength? That is the question. The intestinal microbiota acts on many aspects of our health: digestion, immunity, oral health, intimate comfort, gut-brain axis etc. It would also have an impact on the skeletal muscles. Emerging evidence supports a role for the gut microbiome on the maintenance of lean body mass and physical functioning. Sarcopenia also called muscle wasting is an inevitable phenomenon in aging. With age, body composition, muscle strength and lean body decrease. We lose strength and muscle. Could the intestinal microbiota, which loses richness and diversity in older, play a role? An [...]

Mastitis : probiotics as reinforcement

Laura_Exden2020-05-26T12:40:35+02:0007 February 2020|The Science, Women|Comments Off on Mastitis : probiotics as reinforcement

Becoming a mother is wonderful. The baby’s arrival brings a new dimension to life. Breastfeeding during the first six months of life is highly recommended by the WHO (World Health Organisation) in order to fill the energy and immune needs necessary for the development of child. However, some problems may arise during this period. One of them is mastitis. Indeed, mastitis is the main cause of early weaning. What is mastitis? Mastitis is an inflammatory condition of the breast that can be accompanied by an infection. It is usually unilateral and occurs for 6 weeks after birth (although it can occur [...]

Contact lenses: a device that modifies the ocular microbiota

Laura_Exden2020-05-26T12:42:55+02:0029 November 2019|That's your concern, The Science|Comments Off on Contact lenses: a device that modifies the ocular microbiota

Contact lenses are very useful in everyday life for many people. Indeed, they allow invisible vision correction. Placed directly on the eye cornea, contact lenses offer an excellent field of view. But did you know that the eye is harboring its own microbiota? A bacterial community that provides protection against possible harmful microorganisms? Now, you do. This ecosystem which is present on the eyes’ surface, could be altered when it comes into contact with contact lenses. Wearing lenses changes the ocular microbiota… Lens wearers have a bacteria proportion in the eyes identical to those found on the skin. This outcome results [...]

A pill to learn more about the gut microbiota

Laura_Exden2020-05-26T12:44:36+02:0015 November 2019|The Science, Unusual|Comments Off on A pill to learn more about the gut microbiota

The gut microbiota, an organ difficult to define… The intestinal microbiota… What a vast organ! It consists of a very large number of microorganisms including one hundred thousand billion bacteria, the majority of which is housed in our intestines. Bacteria are ten times more numerous than our human cells. we are largely composed of bacteria, with whom we live in symbiosis. We develop our intestinal microbiota from birth. It becomes more complex with time until it becomes mature after 2-3 years. Very complex and diversified ecosystem, it is at the origin of many health essential functions like the process of digestion [...]

If sports performance depended on an intestinal bacterium?

Laura_Exden2020-05-26T12:48:53+02:0006 September 2019|That's your concern, The Science|Comments Off on If sports performance depended on an intestinal bacterium?

The holidays are over and it is time to go back to school or work. It is also time for good resolutions! And that can go through the resumption of physical activity. But, as you can imagine, we are not all equal: some are good, some are not... Physical performance would be due to a bacterium And if the physical abilities were due to the microbiota composition? This is what are reported the team of Joslin Diabetes researchers after analyzing Boston runners in 2015. Scientists recovered fecal samples from athletes over a 2-week period: from one week before until one week [...]

(Freepik) Rob Knight, a researcher from University of California. He is a recognized scientist in the field of gut microbiota. He has written the book named “Follow your gut” in collaboration with the journalist Brendan Buhler. This book is based on his TED talk (2014) “How our microbes make us who we are”. It gives a general vision of the gut microbiota and current knowledge on it. The author-researcher begins his book on a basic concept. He explains to us that the human being is not alone in his body. Indeed, it lives in symbiosis with innumerable microorganisms having [...]
