pcr identification of meats from chamois rupicapra rupicapra pyrenean ibex capra pyrenaica and mouflon Ovis ammon targeting specific sequences from the mitochondrial d loop region
Meat Science, 2007Co-Authors: Violeta Fajardo, Isabel Gonzalez, Ines Lopezcalleja, Irene Martinez Martin, Maria Rojas, Teresa Garcia, Pablo E Hernandez, Rosario MartinAbstract:A polymerase chain reaction (PCR) assay was developed for the identification of meats from chamois (Rupicapra rupicapra), pyrenean ibex (Capra pyrenaica), and mouflon (Ovis ammon) by using oligonucleotides targeting mitochondrial D-loop sequences. A D-loop region (∼700-1000 bp) was firstly amplified and sequenced from various game and domestic meat DNAs, and three primer sets were then designed on the basis of nucleotide multialignment of the generated D-loop sequences. As expected from sequence analysis, PCR amplification of the targeted D-loop fragments was successfully achieved from chamois (88 bp), pyrenean ibex (178 bp), and mouflon (155 bp) meats, showing adequate specificity and reproducibility against a number of game and domestic meats. Mouflon and sheep meats were amplified together in accordance to the high nucleotide identity of their mt D-loop sequences. In this work, satisfactory amplification was also accomplished in the analysis of experimentally pasteurized (72°C for 30min) and sterilized (121°C for 20min) meats, with a detection limit of ∼0.1% for each of the targeted species. The proposed PCR assay represents a rapid and straightforward method for the detection of possible adulterations in game meat products.

analysis of mitochondrial dna for authentication of meats from chamois rupicapra rupicapra pyrenean ibex capra pyrenaica and mouflon Ovis ammon by polymerase chain reaction restriction fragment length polymorphism
Journal of AOAC International, 2007Co-Authors: Violeta Fajardo, Isabel Gonzalez, Ines Lopezcalleja, Irene Martinez Martin, Maria Rojas, Teresa Garcia, Pablo E Hernandez, Miguel Angel Pavon, Rosario MartinAbstract:The prevention of fraudulent labeling of game meat constitutes an important part of food regulatory control and quality assurance systems. A polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) analysis based on mitochondrial deoxyribonucleic acid (DNA) was developed for authentication of meats from chamois (Rupicapra rupicapra), pyrenean ibex (Capra pyrenaica), and mouflon (Ovis ammon). Amplification and restriction site analysis of a DNA fragment about 720 base pairs (bp) from the mitochondrial 12S rRNA gene of all analyzed species permitted the selection of Msel and Apol endonucleases for meat speciation. The 12S rRNA restriction profiles obtained allowed the unequivocal identification of chamois, pyrenean ibex, and mouflon/sheep and their differentiation from meats of domestic species such as cattle, goat, and swine. The highly variable mitochondrial D-loop gene was also targeted to attempt discrimination between mouflon and sheep meats. A D-loop region (700-1000 bp) was amplified and sequenced in all game and domestic species analyzed, and a primer set was designed for the selective amplification of a 370 bp DNA fragment from mouflon and sheep. PCR-RFLP analysis with the selected Maell enzyme generated a single electrophoretic profile characteristic for sheep, whereas 3 different fragment patterns were obtained for mouflon meats. Consequently, the PCR-RFLP technique developed can be routinely applied in inspection programs in order to verify the correct labeling of game species.
