Furthermore, short sequences allow the accurate massive inter- and intra-species identification of point mutations by the SSCP technique. The size of the amplified segment ranged from 222 to 252 bp. Amplification and identification success were 100% with all kinds of tissue tested in both raw and processed samples in a wind range of species, mammals (n = 27), fishes (n = 32) birds (n = 19), coleoptera (n = 23), reptiles (n = 5), crustaceans (n = 5) and cephalopods (n = 2), including almost all European mammal and avian game species. In addition, no intra-specific polymorphism was detected. Finally, gene fragments, homologous to those amplified by the primers used herein and retrieved from the GenBank for three animal sets [mammals (n = 248), birds (n = 231) and fishes (n = 644)] showed a particular precise percentage of correct identifications. Therefore, this short segment of the 16S rRNA mitochondrial gene could be a good candidate for a rapid, accurate, low-cost and easy-to-apply and interpret method to identify mammal and avian game species by PCR amplification and sequencing that can be easily incorporated in integrated conservation and forensic programmes. 23 pp. LOMv1.0 creator LOMv1.0 Project Final Beneficiary LOMv1.0 Project Executing Organisation LOMv1.0 training LOMv1.0 higher education 18+ Digital Library of the Operational Programme "Education and Lifelong Learning" abstract types Text 16S rRNA Universal primers Species identification Food control Barcoding 629687 application/pdf http://repository.edulll.gr/edulll/bitstream/10795/2407/2/2407_A%20new%20set%20of%2016S%20rRNA%20universal%20primers%20for%20identification%20of.pdf Πανεπιστήμιο Θεσσαλίας.
