Abstract：Skin sites with different properties of 8 pairs of mothers and infants were analyzed for comparison of bacterial communities between mothers and infants using pyrosequencing. The main bacteria for total of skin samples were Actinobacteria, Firmicutes, Proteobacteria and Bacteroidetes. The core members of bacteria on mothers and infants’ skin were similar. However, the abundance was not. The percentage of Propionibacterium was higher in mothers’ skin sites than that in infants’ skin sites (P<0.05). Streptococcus and Staphylococcus were two main genera in infants’ skin. Moreover, Staphylococcus was more abundant on glabella in caesarean-born infants than vaginally born infants (P<0.05). Most of the unique genera detected in infants (Gemella, Prevotella, Rothia and Veillonella) were the common oral bacteria from mothers. It is suggested that oral bacteria from mothers may influence the skin micro-ecosystem of infants in early life. Bacterial communities of each infant were close to his/her mother, while bacterial community structure was similar to other infants. The sebaceous sites of mothers, like glabella and back, showed lower bacterial diversities than other sites. In mother’s samples, sebaceous, moist and dry sites had their own bacterial populations separately. However, in infants’ samples, the bacterial community in back was similar to that in antecubital fossa, and the bacterial community in glabella was similar to that in hand back.
