This video introduces COMRU, the Cambodia Oxford Medical Research Unit, a collaboration between the Angkor Hospital for Children and Bangkok-based Mahidol Oxford Tropical Medicine Research Unit (MORU). Currently run by Dr Claudia Turner and Dr Paul Turner, COMRU works to provide insights into the leading causes of bacterial sepsis among the local Cambodian population. The Unit's new microbiology lab, which opened in June 2013, will allow medical researchers to identify causes of sepsis and sepsis-related death, and facilitate the development of rational approaches to the diagnosis, treatment and management of paediatric infections at the Angkor Hospital for Children and throughout Cambodia.
