| Outline of Final Research Achievements |
We used a high-throughput 454-pyrosequencing strategy to detect diverse aquatic microbes in the lungs (56 specimens) and blood (72 specimens)of 19 drowning and 13 non-drowning victims. This technique was very useful for determining the diversity of aquatic microbes such as bacteria including cyanobacteria, diatoms and other algae in drowning victims. This technique therefore has high potential as a novel molecular tool with which to examine whether an immersed victim has drowned, especially when the results of conventional diatom testing or other useful approaches are equivocal. To the best of our knowledge, this is the first attempt to use a next generation sequencer to investigate diverse aquatic microbes in the lungs and blood of many drowning and non-drowning victims.
