Microbiota Flashcards
Describe the beginging of baby life in relation to microbiota
In the beginning the baby is sterile because it lived in a sterile environment but after birth it will be in touch with the mother’s microbiota and so its skin and so it’s they just if track will get a normal microbiota shared by the mother and then in the years that come the baby will be in touch with a third people animals and objects an enrich its own microbiota
Microbiome central vs secondarie
What is the difference?
The central microbiome is one that is shared among. most people. It’s not really very varied. On the other hand, second. microbiome is a biome that is very specific from one individual to another and varies a lot between species and individuals.
Facteurs externes qui influencent le microbiote (4)
- Hygiène personnel (savon, déodorant, rince-bouche, douche vaginale)
- Diète (riche en fibre, en graisse, en sucre) + diversifiée ou non
- H2O (avec chlore vs eau de puits)
- Prise d’antibiotique

What areas of skin would you excpect to have the most bacteria?
Sweaty parts:
Il est influencé par la présence ou non de glandes sébacées et l’humidité
In which of these ares do we ave the least of bacteria and why?
Saliva
Stomach
Colon
Stomach :
Acid protects against bacteria. What happens when we take an anti-acid -> more bacteria
In the colon
Bactéries _________ strictes plus nombreuses que les bactéries ____________
anaérobies
aérobies
True or False
L’analyse du microbiote ne permet pas de prédire le développement éventuel d’une maladie
True.
At the current age, nothing shows a correlation between microbiota and illness
List the general principales fonctions du microbiote intestinal (3)
1) Fonctions métaboliques
2) Stimule l’immunité innée
3) Prévient la colonisation par des bactéries pathogènes
