Epidemiology of Resistant Microbial Strains Among Different Groups of People (Healthy, Infected and Exposed to Animals) (ABRESIST)

October 10, 2018 updated by: Kaidi Telling, University of Tartu

Transfer Routes of Antibiotic Resistance

This study investigates carriage rate and risk factors for acquiring multiresistant bacteria (ESBL producing E.coli and K.pneumoniae, carbapenem-resistant and multidrug resistant P.aeruginosa, MRSA and VRE) in hospitalised patients and healthy volunteers.
