Investigation of oral swabs taken from newborn infants after breastfeeding.
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.
