Identification of unique bacterial gene segments from Streptococcus mutans with potential relevance to dental caries by subtraction DNA hybridization.
Using DNA subtractive hybridization, 49 unique gene segments were identified from a strain of Streptococcus mutans that was isolated from a patient with severe early childhood caries (S-ECC). Further hybridization with DNA from other S. mutans strains isolated from both caries-active and caries-free subjects yielded five unique sequences of DNA common to strains associated with S-ECC.
