  • The BceABRS four-component system regulates the bacitracin-induced cell envelope stress response in Streptococcus mutans 

    Ouyang, J., X. L. Tian, J. Versey, A. Wishart, et al. 2010. "The BceABRS four-component system regulates the bacitracin-induced cell envelope stress response in Streptococcus mutans." Antimicrobial Agents and Chemotherapy 54(9): 3895-3906.
    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., X. L. Tian, J. W. Gallant, N. Merkley, et al. 2011. "A novel target-specific, salt-resistant antimicrobial peptide against the cariogenic pathogen Streptococcus mutans." Antimicrobial Agents and Chemotherapy 55(11): 5205-5213.
    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., and X. Tian. 2012. "Quorum sensing and bacterial social interactions in biofilms." Sensors (Basel, Switzerland) 12(3): 2519-2538.
    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., X. L. Tian, K. Sampara, A. Salman, et al. 2007. "Structure-activity analysis of quorum-sensing signaling peptides from Streptococcus mutans." Journal of Bacteriology 189(4): 1441-1450.
    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 ...
