Importance of forensic entomology becomes inevitable when come across some incident where corpse is unidentifiable and lot of maggots or other insects are present. The most common application of forensic entomology is to use insects for the identification of specimens or human remains. DNA analysis recovered from a larva's gut contents can be used to identify a missing body. The obtained human STR and SNP profile support the association of a maggot to a specific patients or corpse. Main aim of this research was the identification of human DNA from gut contents of third instar maggots (larvae of Lucilia sericata) placed on diabetic patient's wounds for treatment purpose. Maggots (8-15) were taken from each diabetic patients (no. of the patients 8) and DNA was extracted from the gut contents manually by using Qiagen tissue protocol. Agarose gel electrophoresis was performed and the total size of DNA was seen using UV transilluminator. PCR amplification, STRs and SNPs profiling was then performed using PCR 9700 and AmpFLSTR Identifiler and SnaPshot Multiplex Kit (Applied Biosystems) respectively. The results were analyzed on ABI 310. SNP profiles were good and identifiable compared to the STRs where amplification was poor and the peaks were low. This may be the fact of the enzymatic activity present in the gut of the larvae which cause tremendous reduction in DNA size and thus yield. The results of this study reveals that it is possible to obtain a complete human profile using STRs and SNPs even if DNA is recovered from gut contents of maggots. © 2009 Elsevier Ireland Ltd.
