| Outline of Final Research Achievements |
This study aimed to develop a comprehensive quantification method for over 900 species of pathogenic bacteria and to clarify the occurrence of those pathogenic bacteria in the aquatic environment using the developed method. To these aims, this study tried to develop a selective detection method of viable bacteria in water using DNA intercalating treatment, to develop a quantitative DNA microarray method to simultaneously quantify over 900 pathogenic bacterial species, and to understand the occurrence of pathogenic bacteria in aquatic environments in Japan and other countries. Results of this study clarified the DNA intercalating treatment conditions useful for various bacterial species to some extent, and showed some important hints for the establishment of a quantitative DNA microarray method. In addition, this study could grasp the occurrence of over 900 pathogenic bacterial species in the Sagami River basin and in water samples collected from the Kathmandu valley, Nepal.
