The continuous increase in the multidrug resistance of clinical pathogens is recognized as a major public health threat. However, there is limited knowledge of the pathogenesis at the cellular and molecular levels of clinical bacterial strains. Subsequently, treating such infections is becoming more difficult for both hospitals and governments. Therefore, understanding such bacterial pathogenesis is necessary to develop more effective antibiotic treatments. Our research group is interested in finding the molecular and biochemical mechanisms contributing to bacterial resistance. In addition, we are also exploring the “Host-Pathogen” interactions via post-translational modifications, which could help to develop intervention strategies and provide insights into disease progression.
