The BceABRS four-component system regulates the bacitracin-induced cell envelope stress response in Streptococcus mutans
Ouyang, J.; Tian, X. L.; Versey, J.; Wishart, A.; Li, Y. H. (2010-09)Streptococcus mutans is known to be resistant to bacitracin, a cyclic polypeptide antibiotic produced by certain species of the genus Bacillus. This property is often exploited in the isolation of S. mutans strains from ... -
A novel target-specific, salt-resistant antimicrobial peptide against the cariogenic pathogen Streptococcus mutans
Mai, J.; Tian, X. L.; Gallant, J. W.; Merkley, N.; Biswas, Z.; Syvitski, R.; Douglas, S. E.; Ling, J.; Li, Y. H. (2011-11)In this study, we constructed and evaluated a target-specific, salt-resistant antimicrobial peptide (AMP) that selectively targeted Streptococcus mutans, a leading cariogenic pathogen. The rationale for creating such a ... -
Quorum sensing and bacterial social interactions in biofilms
Li, Y. H.; Tian, X. (2012)Many bacteria are known to regulate their cooperative activities and physiological processes through a mechanism called quorum sensing (QS), in which bacterial cells communicate with each other by releasing, sensing and ... -
Structure-activity analysis of quorum-sensing signaling peptides from Streptococcus mutans
Syvitski, R. T.; Tian, X. L.; Sampara, K.; Salman, A.; Lee, S. F.; Jakeman, D. L.; Li, Y. H. (2007-02)Streptococcus mutans secretes and utilizes a 21-amino-acid signaling peptide pheromone to initiate quorum sensing for genetic competence, biofilm formation, stress responses, and bacteriocin production. In this study, we ...
