| Outline of Final Research Achievements |
Occurrence of resistant bacteria in Asian river basin such as Japan, China and Bangladesh was surveyed in this research. From the results in the Katsura river, Japan, ratio of resistant bacteria and values of Multi-Antibiotic Resistance (MAR) index for sewage effluents were higher than these for river water, which indicates that sewage effluents will be important sources of resistant bacteria in river basin. Similar results were obtained from the survey in China and Bangladesh river basin. On the MAR index obtained from Asian river basin, the values in Bangladesh were higher than these in Japan.
