A Smart Surveillance Strategy for Carbapenem-resistant Pseudomonas aeruginosa (SAMPAN)

Pseudomonas aeruginosa causes severe infections in hospitalized patients. The worldwide emergence of carbapenem-resistant P. aeruginosa (CR-PA) makes infections by these pathogens almost untreatable. The World Health Organization now ranks CR-PA highest in the list of ‘urgent threats’.

Ongoing project

Information for action to prevent further emergence has to come from insight into sources and transmission routes through smart surveillance. At present, a smart surveillance strategy is not available for CR-PA.

The aim of this project is to develop a globally-applicable smart surveillance strategy to guide action against the spread of CR-PA. Since P. aeruginosa prefers moist niches, we will focus on the human-water interface. First, highly-sensitive methods to detect CR-PA in specific environmental and human niches will be developed. Subsequently, CR-PA will be collected in three study sites with increasing prevalences of CR-PA, increasingly warmer climates, and different water situations: Rotterdam (The Netherlands), Rome (Italy), Jakarta (Indonesia). CR-PA will be searched for in a variety of niches in the environment outside and inside the hospital, and in healthy humans and hospitalized patients. Whole genome sequencing will be performed to compare the CR-PA from different sources and identify transmission routes.

Our project will provide insight into the relative contribution of the different potential reservoirs of CR-PA to its spread in different settings which will be used for the development of a globally-applicable surveillance strategy for CR-PA to guide preventive actions.
