The Antibacterial Efficacy Of Silver (I) Cyanoximates Against Streptococcus Mutans Ua159 Biofilm Growth And Infection In Galleria Mellonella Larvae, Jill Hughes
Honors Program Theses
Streptococcus mutans is the known etiological agent of dental caries. S. mutans’ virulence factors, namely biofilm formation and lactic acid fermentation, contribute to its pathogenic behavior within the oral cavity. Biofilms are thick, antibiotically resistant communities of bacteria that are much more difficult to treat than planktonic or free-floating bacteria. Continued misuse of antibiotics against dynamic communities, like biofilms, has led to increased research on non-antibiotic alternatives. Amongst these alternatives, there are silver and silver-based compounds. Silver is commonly incorporated into medicine due to its inhibitory and bactericidal effects and antibacterial properties. Silver (I) cyanoximates have demonstrated promising antibacterial activity …

The Role Of Cody In Hydrogen Peroxide Tolerance And Biofilm Formation Of Streptococcus Mutans, Kaitlin M. Rioux, Brandaliz Santiago-Narvaez
Honors Program Theses
Streptococcus mutans is the major cariogenic bacterium in the oral cavity. S. mutans causes disease by three main virulence factors: acid production, acid tolerance, and biofilm formation. S. mutans outcompetes various other species in the oral cavity, however it is affected by hydrogen peroxide production by these species. Based on previous findings and this research, hydrogen peroxide is shown to extend the lag phase of S. mutans but does not kill it unless present in extremely high amounts that are generally not produced by commensal species like S. sanguinis and S. gordonii in the oral cavity. CodY is a global …
