Africa-Press – Senegal. <\/strong><\/span>Les buveurs de cafe\u0301 he\u0301bergent dans leur microbiote intestinal une bacte\u0301rie qui se de\u0301lecte aussi particulie\u0300rement du breuvage, re\u0301ve\u0300le une vaste e\u0301tude e\u0301pide\u0301miologique mene\u0301e par une e\u0301quipe italo-ame\u0301ricaine. Pour la premie\u0300re fois, une espe\u0300ce bacte\u0301rienne est associe\u0301e a\u0300 un aliment bien spe\u0301cifique consomme\u0301 par une grande partie de l\u2019humanite\u0301.<\/p>\n

Les chercheurs ont compare\u0301 le microbiote intestinal de 22.000 personnes issues de 43 pays en se\u0301quenc\u0327ant l\u2019ADN bacte\u0301rien de leurs fe\u0300ces. Sur les 115 espe\u0300ces bacte\u0301riennes dont les effectifs augmentaient avec la consommation re\u0301gulie\u0300re de cafe\u0301, la bacte\u0301rie Lawsonibacter asaccharolyticus sortait du lot en e\u0301tant jusqu\u2019a\u0300 huit fois plus abondante chez les amateurs de cafe\u0301, et cela quel que soit leur a\u0302ge, leur sexe ou leur e\u0301tat de sante\u0301. Cette bacte\u0301rie, re\u0301cemment identifie\u0301e dans le co\u0302lon humain, e\u0301tait fre\u0301quente dans les populations ayant un mode de vie occidental mais restait rare chez les enfants et le singe.<\/p>\n

Une forte consommation de cafe\u0301 ne semble pas nocive pour le microbiote<\/b><\/p>\n

Sa pre\u0301sence, indique l\u2019e\u0301tude publie\u0301e dans la revue scientifique Nature Microbiology, e\u0301tait associe\u0301e a\u0300 celle dans le sang de produits de de\u0301gradation des acides chloroge\u0301niques, des polyphe\u0301nols pre\u0301sents en abondance dans le cafe\u0301. Ces substances peuvent a\u0300 leur tour favoriser la prolife\u0301ration d\u2019autres types de bacte\u0301ries be\u0301ne\u0301fiques du microbiote intestinal. Une tre\u0300s forte consommation de cafe\u0301 n\u2019entrai\u0302nait cependant pas plus de changements dans les populations bacte\u0301riennes qu\u2019une consommation mode\u0301re\u0301e et ne semble donc pas nocive pour l\u2019e\u0301quilibre du microbiote intestinal.<\/p>\n

Le cafe\u0301 doit-il ses proprie\u0301te\u0301 be\u0301ne\u0301fiques a\u0300 cette bacte\u0301rie?<\/b><\/p>\n

In vitro, la croissance de la bacte\u0301rie e\u0301tait la seule a\u0300 e\u0302tre stimule\u0301e par le cafe\u0301, qu\u2019il soit avec ou sans cafe\u0301ine, l\u2019alcaloi\u0308de psychoactif du cafe\u0301. Les chercheurs soulignent que de nombreuses espe\u0300ces bacte\u0301riennes du microbiote intestinal humain re\u0301agissent au cafe\u0301 mais restent a\u0300 identifier car elles sont difficilement cultivables et meurent en pre\u0301sence d\u2019oxyge\u0300ne. De futures recherches de\u0301termineront si c\u2019est a\u0300 elles, avec L. asaccharolyticus, que le cafe\u0301 doit ses proprie\u0301te\u0301s be\u0301ne\u0301fiques pour l\u2019organisme.<\/p>\n
