MedVetKlebs is a multidisciplinary international project that aims to define the ecology of Klebsiella pneumoniae (Kp) and the sources of infections of humans and animals in order to investigate transmission routes and to find an optimal way to control them.

Klebsiella pneumoniae (Kp) is a major cause of hospital-acquired infections such as pneumonia, bloodstream infections, infections in newborns and intensive-care unit patients. In 2014, WHO’s global report on AMR revealed that the resistance to the treatment of last resort (carbapenem antibiotics) for life-threatening infections caused by a common intestinal bacteria, Klebsiella pneumoniae (Kp), has spread to all regions of the world. In the western world, kp represents nearly 10% of nosocomial infections and is one of the most problematic multidrug resistant (MDR) organisms, with increasing resistance to carbapenem and other ‘last resort’ antimicrobial agents (colistin, tigecycline). The European Parliament report on Antimicrobial Resistance (IP/A/STOA/SC/2005-173) stated: “The increasing development of such pan-resistant organisms has the potential to become a worldwide catastrophe.”

In this context, MedVetKlebs aims to improve of public and animal health through a better control of Kp infections by:

  1. Developing and harmonizing detection and isolation methods;
  2. Ensuring a broad sampling of ecological niches and deep sampling of potential sources;
  3. Performing genomics analysis and transmission modeling, including development of new methods for source attribution and risk assessment.

To achieve the above objectives, MedVetKlebs brings together partners from different sectors (fundamental microbiology, medical, veterinary, food, environmental sectors, and bioinformatics) located in different European countries in order to ensure sufficient geographical coverage of sampling.

Furthermore, MedVetKlebs will develop an efficient scheme of dissemination and implementation of obtained results to all concerned parties and to general public.
