Scientific breakthroughs made during 2017 can change the lookout of forensic medicine experts. Here, Docplexus brings you the top discoveries made this year that may be practically helpful to solve even the most challenging medico-legal and criminal cases. Oral bacteria can help you to estimate the time since death The complexity of the oral microbiome is second to that of the gastrointestinal tract. These microorganisms lead to decomposition of the deceased after death.
As the cadaver decays, the diversity of the microbiome alters. Oral swabbing is done regularly since receiving the cadaver and the DNA is extracted from it. The DNA is analyzed through polymerase chain reaction (PCR), next-generation sequencing followed by bioinformatics analysis. The analysis shows different bacterial composition throughout the 5 decay stages: fresh, bloat, active decay, advanced decay and putrid dry…
