Outline of Final Research Achievements

It has been shown that the gut microbiota plays an important role in the whole body immune system and it may affect patient's prognosis and infectious complications in emergency patients. In recent years, it has become possible to analyze comprehensive bacterial mirobiota by high-throughput sequencer. This study revealed the dynamic gut microbiota changes in the acute phase of severe emergency patients and that the antibiotics and the severity of the disease had some effect on gut microbiota change. Also, it was revealed that each patient had a unique gut microbiota at the time of arrival and that the gut microbiota shifted especially up to one week after hospitalization, and thereafter it shifted to a new and static state. It was also shown that the deviation of excessive intestinal flora may adversely affect the life prognosis of the host patient.
