جامعه ی میکروب هایی که درون (یا حتی روی) بدن انسان زندگی می کنند، به همان اندازه که ممکن است خطرساز و بیماری زا باشند، مهم و کارگشا هستند. شاید ما قادر به دیدن شان نباشیم، اما نه میلیون، نه میلیارد، بلکه تریلیون ها باکتری، ویروس، قارچ و دیگر ارگانیسم های زنده و میکروسکوپی درون بدن ما زندگی می کنند. از پوست و داخل دهان گرفته تا درون روده.
همانند انسان که طی صدها هزار سال تکامل یافته، این ارگانیسم ها هم سیر تکاملی خود را طی کرده اند و هر چه بیشتر به نقش آن ها در بدن خود پی می بریم، به اهمیت شان افزوده می شود. میکروب ها همه جا نقش دارند و زندگی بدون آن ها امکان پذیر نیست.
با این حال، هنوز نکات بسیاری است که ما نمی دانیم ولی طی 20 سال گذشته، اطلاعات و حقایق بسیاری رو شده که به افزایش کیفیت سلامت و زندگی کمک شایانی کرده است. در ادامه می خواهیم 30 حقیقت جالب علمی را در این رابطه مرور کنیم.
