METHOD OF ANALYZING INTESTINAL FLORA AND ANALYTICAL APPARATUS

摘要

A method of analyzing intestinal flora which comprises: collecting a sample from a subject; extracting bacteria to give a suspension of the bacteria; extracting bacterial DNAs from the suspension to give a DNA extract; using the DNA extract in amplifying a specific domain such as 16SrDNA; fractionating the thus amplified fragments by electrophoresis to give a fractionation pattern; and comparing the fractionation pattern with preliminarily obtained electrophoretic patterns of amplified fragments of intestinal flora, thereby analyzing the intestinal flora of the subject.
