Investigation of Streptococci in Oral Flora in Terms of Identification in Forensic Sciences

Abstract

Objective:Forensic Microbiology, which is a new field and mentioned about these microscopic evidences in forensic science, comes into question in terms of defining microorganisms for protecting innocents and defining guilty as a result of changing social life. Considering that oral microflora streptococcus might be on various objects, this study was planned to investigate whether these microorganisms could be used in forensic identification.Methods:In this study, 200 different swab mediums, including mouth, apple, chewing gum and cigarette swabs of 50 people, underwent the culture growth process. All microorgnisms of the individuals in oral microfloras were examined. According to the obtained data, alpha hemolytic streptococci was detected to be the most predominant species among these microorganisms. The presence of some rare microorganisms in individuals’ oral floras was found to make them special for indentification. In this case, it has been possible to say that microorganisms existing in the bite mark left in any place, in any event and in any objects will be an evidence that can cause that person to be caught.Results:In this respect, this study, which is carried out in the case of degraded or insufficient DNA procedure obtained from the bite marks of the suspects in the criminal investigation or in order to obtain a complementary result in addition to genotypic approaches, has been brought to forensic sciences.Conclusion:A contribution was made to identification with a different approach to these bacteria Streptococcus, which are important for clinics and forensic science.
