Transmission of mutans streptococci.
It has been shown that early establishment of mutans streptococci in the mouth of infants increases risk of caries. Extensive studies on the timing of infection, and on sources and routes of transmission of the organism have been performed. Results of many studies suggest that the source of mutans streptococci is the mother, especially her saliva. Methods used to attempt to verify this hypothesis have developed considerably in recent years. Recent research and work in progress using methods based on DNA analysis have increased and will extend knowledge about transmission. This review summarizes the results obtained by different methods of transmission of mutans streptococci. The final goal of studies is to accumulate adequate information for prevention strategies of mutans streptococcal infection.
