Dysbiosis (also called dysbacteriosis) is a term for a microbial imbalance on or inside the body. Dysbiosis is most commonly reported as a condition in the digestive tract. It has been reported to be associated with illnesses, such as inflammatory bowel disease, chronic fatigue syndrome, obesity, cancer,〔 〕 bacterial vaginosis, and colitis. Typical microbial colonies found on or in the body are normally benign or beneficial. These beneficial and appropriately sized microbial colonies carry out a series of helpful and necessary functions, such as aiding in digestion. They also help protect the body from the penetration of pathogenic microbes. These beneficial microbial colonies compete with each other for space and resources and outnumber human cells by a factor 10:1. The term "dysbiosis" is not a standardized medical term. Apparently similar concepts are also described as "microbial imbalance", "bacterial imbalance", or "increased levels of harmful bacteria and reduced levels of the beneficial bacteria".〔http://news.harvard.edu/gazette/story/2014/03/imbalance-in-microbial-population-found-in-crohns-patients/〕 == Causes == Dysbiosis may be caused by such diverse things as repeated and inappropriate antibiotic exposure, alcohol misuse, or inappropriate diet. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「dysbiosis」の詳細全文を読む スポンサード リンク
