Objective:to study the level of total anaerobic population, total aerobic population, four kinds of anaerobes and two kinds of aerobes in excrement of sufferers of varies kinds of irritable bowel syndrome and that of normal persons. methods:excrement specimens from 52 ibs sufferers of different kinds and that of 18 normal volunteers were collected, and the level of four kinds of anaerobes and two kinds of aerobes were quantified. results:the level of total anaerobic population and total aerobic population of excrement specimens of three kinds of ibs sufferers were different significantly, particularly the level of bifidobacterium and cillobacterium(p.01the level of bacteroid population was higher significantly in diarrhea-predominant and mixed type of ibs sufferers (p.01the level of enterococcus population was higher significantly in diarrhea-predominant ibs sufferers(p.05among the aerobes, the number of escherichia coli and staphylococcus aureus colonies were increased by different level(p.01or0.05) in the ibs suffers, in particular, the number of escherichia coli colonies in diarrhea-predominant ibs sufferers increased most significantly. conclusion:sufferers of different types of ibs have different intestinal tract dysbacteria phenotypes.
