ABSTRACT
Objective To develop a PCR-based method of detecting plankton 16S rDNA for the i dentification of death by drowning. Methods Fifteen Sprague-Dawley rats were divided randomly into three groups the death by drowning group, the group of submerging after death and the control group. After sacrificing by different ways, the brain, liver, kidney and lung of rats were taken out respectively and DNA were extracted from the tissues of these organs and were amplified subsequently by specific primers selected from the third and fourth variable regions of plankton 16S rDNA. Results The specific amplification products were detected from all 5 samples of lung tissue ( 100% ) , 4 samples from liver and kidney tissues (80% ) , and 3 samples from brain tissue (75% ) in the group of death by drowning. No amplification product was detected in all samples of the control group and the amplification product was detected only in 1 sample of lung (20% ) in the group of submerging after death. Conclusion The PCR-based method of detecting plankton 16S rDNA for the identification of death by drowning is certainly feasible.
