RESEARCH INTERESTSDr. Lauderdale's research interests include phenotypic and genotypic surveillance of antimicrobial resistant bacteria. The main project of her laboratory is the Taiwan Surveillance of Antimicrobial Resistance (TSAR) program, which surveys bacterial pathogens isolated from inpatients and outpatients in Taiwan hospitals. Surveys on resistant bacteria that could be transmitted via the food chain to humans are also conducted. Studies on the molecular epidemiology of and mechanisms of resistance in methicillin resistant Staphylococcus aureus (MRSA), vancomycin resistant enterococci (VRE), and fluoroquinolone resistant bacteria have also been ongoing.
RESEARCH ACTIVITIES & ACCOMPLISHMENTSFour rounds of TSAR have been completed since 1998, and the fifth round (TSAR V) is ongoing to provide longitudinal national trends on antimicrobial resistance. Surveillance of resistant bacteria in food animals also provides insight into the potential impact of antimicrobial use in agriculture on human medicine. Recent publications include changes in VRE prevalence in food animals; plasmid mediated fluoroquinolone resistance in a Klebsiella pneumoniae strain; serotype distribution and prevalence of antimicrobial resistance in Salmonella spp. and Streptococcus pneumoniae; and molecular epidemiology of MRSA in Taiwan.
