Research Focus

Bacterial lung infections and – more generally – sepsis, contribute massively to worldwide morbidity and mortality. Most of this impact occurs in the poorer regions of the world. My research incorporates several different approaches to address the burden of bacterial lung infection and sepsis in these settings. These activities comprise some of the projects in a new multidisciplinary initiative called the UW International Respiratory and Severe Illness Center (INTERSECT).

First, a better understanding of innate immunity may permit the development of new strategies or targeted therapies combating lung infection and sepsis. Toward this end, I investigate the role of pathogen recognition receptor signaling in melioidosis, a particularly nasty disease caused by the intriguing Gram-negative bacterium Burkholderia pseudomallei. Melioidosis is endemic in parts of southeast Asia and tropical Australia, and often presents as a lung infection or sepsis. I combine murine models of disease and in vitro studies with analyses of human genetic variations in Thai patients with melioidosis to gain insights into innate immune responses precipitated by B. pseudomallei. The clinical significance of another better known pathogen, Staphylococcus aureus, is unfortunately underestimated in much of Asia. In related work, I engage in studies examining the association of functional innate immune genetic variation with outcome in invasive S. aureus infection in rural Thailand. These projects are all undertaken in very close cooperation with researchers from the Mahidol-Oxford Tropical Medicine Research Unit, Bangkok and Sappasithiprasong Hospital, Ubon Ratchathani, Thailand.

Second, improved recognition and management of septic patients has the potential to save huge numbers of lives in low resource environments, where outcomes from sepsis are dire. Unfortunately, most sepsis care efforts are not directed at these settings. I participate in the development and testing of severe illness and sepsis management strategies modified for low resource regions. This work is performed with members of the World Health Organization’s Integrated Management of Adolescent and Adult Illness team and the Global Alert and Response group.

MORU Researchers

Researchers at the Mahidol-Oxford Tropical Medicine Research Unit
(MORU) identify about 400 cases of melioidosis annually at
Sappasithiprasong Hospital. This is the largest existing cohort of
melioidosis patients. Here, laboratory staff screen patient samples
for B. pseudomallei using selective Ashdown agar.
