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.
摘要
介绍了热解质谱法（Py-MS）及质谱统计分析作为一种对唾液链球菌菌株进行“指纹识别”的方法。目的是为涉及咬痕的袭击或强奸案件中的嫌疑人身份提供相关证据。展示了对来自两个人的分离株的分析结果，说明了根据分离株来源在菌株水平上对唾液链球菌的区分。
