Lecture 1: "Biofilms and Caries: Sisyphus Meets Streptococcus Mutans" Dr. Burne's first lecture focuses on Streptococcus mutans, a bacterium commonly found in the mouth, and other organisms that contribute to the initiation and progression of tooth decay. This presentation also discusses molecular, genetic, biochemical, ecological and clinical studies that ilustrate dental caries; resistance of antagonistic interactions between commensals and cariogenic organisms.
Lecture 2: "Complexities in Catabolite Modification of Gene Expression in Streptococcus Mutans"
Dr. Burne's second lecture focuses on genetic and biochemical studies which show that Streptococcus mutans has developed a complex, hierarchical regulatory network that includes diverse transcriptional regulators and multpiple components of the sugar phosphotransferase system. This hierarchical regulatory network also coordinates carbon and energy metabolism in response to diverse environmental and intercellular signals.
