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 [...]

Book – À fleur de pet
Dora Moutot, journalist, wrote the book “À fleur de pet” based on her experiences. A complicated medical journey A true sharing of her story, in which she explains her symptoms and her complicated medical journey. Her suffering is both physical and mental with a disease not understood. Indeed, gas and bloating punctuate her life and no solution seems to answer these problems. Social isolation, misunderstanding of health professionals and those around them, stress, embarrassment and untimely pain are part of her daily life. Doctors diagnose her with functional colopathy, also known as irritable bowel syndrome. Unfortunately, this is a label that [...]

Helping women through a vaginal microbiota transplantation
Inspired by fecal transplantation, an American team of scientists wants to develop vaginal microbiota transplantation. For what? Help women with bacterial vaginosis. What is bacterial vaginosis? 15 to 20% of French women have already had bacterial vaginosis. And you may have already suffered from it. It is a very common vaginal infection related to dysbiosis of the vaginal microbiota. It is contracted especially when the vaginal pH becomes too alkaline. This multi-microbial infection is characterised by the significant growth of bacteria such as Gardnerella vaginalis for example, to the detriment of the beneficial bacteria constituting the vaginal microbiota. Often without any symptoms [...]

The 100 main concepts to know about the intestinal microbiota, probiotics and prebiotics
This is the 100th blog post! And to celebrate, nothing better than sharing 100 concepts to know about the different subjects of our profession: the intestinal microbiota, probiotics and prebiotics. Intestinal microbiota 1.The most talked about microbiota is the intestinal microbiota 2.However, there are other microbiota: oral, skin, vaginal, pulmonary 3.Nevertheless, 95% of our bacteria are concentrated in the gastrointestinal tract 4.The gut microbiota is made up of about 100,000 billion microorganisms 5.Which represents almost 10 times the number of human cells 6.These bacteria are 10 to 50 times smaller than our cells 7.Bacteria, fungi, [...]

Book – Les bactéries, des amies qui vous veulent du bien
The intestinal microbiota is a large ecosystem with no less than 100,000 billion bacteria. But are these bacteria our “friends”? Pr. Gabriel Perlemuter and Dr. Anne-Marie Cassard are demonstrating this idea in their book: Les bactéries, des amies qui vous veulent du bien – Le bonheur est dans l’intestin. The hygienist theory, a plague for our bacteria Bacteria have long been considered harmful and that is why, as human beings, we sought to eliminate them. We looked for every possible means to eradicate them in order to constitute aseptic environments: this is the hygienist theory. However, we live in symbiosis with [...]

Book – Jamais seul
The Eukaryotes, to which we belong, are never alone: “they have acquired their main energetic metabolisms of bacteria which they have packaged into their cells and which have become hereditary”. This quote from the excellent book “Jamais seul” written by Marc-André Selosse, reflects quite well the author’s idea: organisms resulting from the evolution of living world have always dealt with bacteria. The author therefore offers us a vision of the original life and sometimes confusing due to the systematic presence of microorganisms in biological processes. A book that teaches us perfectly the symbiosis notion, described through many examples in the unicellular, [...]

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 [...]
