Outline of Final Research Achievements

The pathogenic expression process of Staphylococcus aureus (S.aureus) was mathematically analyzed by employing numerical simulation techniques. The pathogenic gene expression level showed a significant fluctuation in the late incubation period. From a perspective of biophysics, the increasing in fluctuation was identified a presymptom of pathogenic expression. Moreover, an inhibition of the fluctuation arrested the pathogenic expression. The realization of the inhibition could contribute to a development of novel therapeutic system which maintains S.aureus in bacteriostatic condition.
