[Determination of the presence of traces of biological material using molecular genetics]

Polymerase chain reaction is often used for molecular genetic human identification in forensic medicine today. In this study, the possibilities are demonstrated, which are provided by the method in such cases, where it is necessary to determine, if the biological traces are of animal or human origin. The method is rapid and well performed in a molecular genetic laboratory with standard equipment. Eleven samples of DNA isolated from different animals and birds were examined. In all cases, it was possible to distinguish these samples according to the results of reaction from simultaneously examined human DNA.
