The aim of this study was to investigate the influence of breastfeeding on the DNA-profiles from oral swabs of newborn babies. Five mother and child pairs were asked to provide orals swabs from the mother and from the child before and immediately after nursing. Investigation of the samples revealed no maternal alleles in the saliva samples of the child taken directly after breast feeding. Therefore, we conclude that nursing does not influence the STR-typing of oral swabs taken form newborn infants. A possible explanation could be that the DNA content of mother's milk is significantly lower than the DNA content of saliva.
本研究的目的是调查母乳喂养对新生儿口腔拭子DNA图谱的影响。五对母婴被要求在哺乳前和哺乳后立即提供母亲和孩子的口腔拭子。对样本的调查显示，母乳喂养后立即采集的孩子唾液样本中没有母亲的等位基因。因此，我们得出结论，哺乳不会影响从新生儿采集的口腔拭子的STR分型。一个可能的解释是母乳中的DNA含量明显低于唾液中的DNA含量。
