Random amplified polymorphic DNA (RAPD) is one of the most promising methods for distinguishing individual bacterial strains and determining the diversity of nucleotide sequences. Eight isolates (identical in 16S rRNA sequence) of Streptococcus salivarius before and after Listerine using In vivo were subjected to RAPD technique showed four strains identical along DNA while other four were not meaning the strains after Listerine using had mutations along DNA strand.
