Docteur Pichon, est-ce que vous pouvez nous expliquer ce qu\u2019est le microbiome <\/strong>?
Le microbiome est une notion r\u00e9cente qui traduit un vieux terme que l\u2019on conna\u00eet tous : la flore microbienne. Le microbiome se d\u00e9finit par l\u2019ensemble des micro-organismes pr\u00e9sents chez un h\u00f4te, humain ou non. Ces derniers regroupent les bact\u00e9ries, les virus et les champignons. Il faut savoir que nous vivons avec des milliards de bact\u00e9ries sans pour autant d\u00e9velopper des pathologies infectieuses et, finalement, peu de monde en a conscience. Dans l\u2019imaginaire collectif, une bact\u00e9rie \u00e9quivaut \u00e0 une maladie. C\u2019est beaucoup plus complexe que cela. Il faut savoir que nous sommes compos\u00e9s de quelques 10 000 milliards de cellules et de dix fois plus de bact\u00e9ries !<\/p>\n\n\n\n

Cela signifie que les bact\u00e9ries ne sont pas nos ennemies <\/strong>?
Bien au contraire ! Nous avons besoin de ces bact\u00e9ries pour prot\u00e9ger notre syst\u00e8me digestif, respiratoire, reproductif, etc. C\u2019est ainsi que nous avons un microbiote intestinal, un microbiote pulmonaire, un microbiote cutan\u00e9, et je pourrais vous en citer encore beaucoup. J\u2019aime le concept de \u00ab paix arm\u00e9e \u00bb pour d\u00e9crire notre cohabitation avec ces bact\u00e9ries. En r\u00e9alit\u00e9, si nous ne tombons pas malades, c\u2019est parce que notre syst\u00e8me immunitaire (dont les globules blancs et les anticorps) contr\u00f4lent le d\u00e9veloppement de ces bact\u00e9ries, et donc leur pouvoir pathog\u00e8ne. En cas de d\u00e9s\u00e9quilibre (ou dysbiose), une infection se d\u00e9clare. Par exemple, c\u2019est en partie pour cette raison que les personnes immunod\u00e9prim\u00e9es d\u00e9veloppent des pathologies infectieuses que les autres ne d\u00e9clarent pas. <\/p>\n\n\n\n

Concr\u00e8tement, comment fonctionne le microbiote et \u00e0 quoi sert-il<\/strong> ?
Les bonnes bact\u00e9ries emp\u00eachent celles qui sont pathog\u00e8nes de se d\u00e9velopper. Dans l\u2019intestin, elles servent, par exemple, \u00e0 d\u00e9truire des d\u00e9chets toxiques ou \u00e0 en prot\u00e9ger les parois. La flore cutan\u00e9e va servir \u00e0 prot\u00e9ger la peau et \u00e9viter que des coupures s\u2019infectent. Autre exemple, un
b\u00e9b\u00e9 qui na\u00eet par voie naturelle s\u2019impr\u00e8gne du microbiome vaginal de sa m\u00e8re ce qui va lui permettre, de d\u00e9velopper \u00e0 son tour un microbiome diversifi\u00e9.
