Human exposure to Leptospira in the Koh Thum district, Cambodia

Human exposure to Leptospira in the Koh Thum district, Cambodia

Since July 2021, the Medical Biology Laboratory of the @Institut.Pasteur.Cambodge and @IrdinAsia (#LMI_DRISA_MIVEGEC) are conducting monthly field samplings as well as soil/water measurements in the Koh Thum District to explore waterborne bacteria and their dynamics as part of the #WatHealthinterdisciplinary project. 

The presence of Leptospira and Burkholderia, responsible for human waterborne diseases has been detected in soil and water and the genetic identification of bacteria is ongoing.

In parallel, human exposure to leptospirosis in the Koh Thum district is currently estimated by serological experiments in the frame of the Master “Infectiology” internship (UHS, UPSaclay). These data will allow us to better understand the circulation and transmission of Leptospira by identifying spatiotemporal/environmental determinants.

Serological experiments: V. Pok (Master 2 student), M. Hidé (IRD), S. Meng (LBM-IPC)

The #WatHealthproject (Water and Health Risks in Cambodia 2021-2022,, is funded by the Solidarity Fund for Innovative Project (FSPI) program supported by the French Ministry of Europe, International Affairs (MEAE) and the French Embassy in Cambodia.
