Melioidosis, host-pathogen interaction



I am an Associate Professor at Mahidol University. I have studied the interactions between the pathogen and human host in melioidosis for over twenty years, combining laboratory investigation with clinical studies. Based in the Department of Microbiology and Immunology, Faculty of Tropical Medicine at Mahidol University in Bangkok. I have conducted or been involved in numerous studies relating to melioidosis and other bacterial infections in northeast Thailand. For example, my Wellcome Trust Intermediate Fel­lowship Project, “Association between genetic polymor­phisms, innate immune responses and outcomes from sepsis in Thai patients with melioidosis and S. aureus infection” involved recruitment of hospitalized patients at four clinical sites in northeast Thailand: Ubon Rachathani, Udon Thani, Khon Kaen and Srinagarind Hospitals. I have worked since 2006 on studies of host genetic susceptibility, human inflammatory responses and laboratory diagnosis. I have developed a substantial repertoire of expertise in immunology, bacteriology, molecu­lar diagnostics, and bacterial and host genetics pertaining to melioidosis. I am currently a principal investigator of NIH/NIAID grant for the project “Determinants of outcomes and reinfection in melioidosis”. This project involved recruitment of melioidosis patients at nine study sites in northeast Thailand.
