| Abstract: | The use of pyrolysis mass spectrometry (Py-MS) and statistical analysis of mass spectra is introduced as a method for “finger-printing” strains of Streptococcus salivarius. The objective is to provide correlative evidence regarding the identity of suspects in cases of assault or rape involving bite-marks. The results of the analysis of isolates from two individuals are presented, illustrating the differentiation of S. salivarius at strain level according to the origin of the isolate. |
