Modification of an effector strain for replacement therapy of dental caries to enable clinical safety trials
10 Apr 2007
Abstract excerpt
AIMS: To construct a genetically modified strain of Streptococcus mutans for dental caries prevention. The strain has significantly reduced cariogenicity owing to a deletion of the entire open reading frame for lactate dehydrogenase, and has excellent colonization potential through the production of a natural antibiotic called mutacin 1140. For use in human clinical trials, additional mutations were introduced to...
