Populærvitenskapelig sammendrag av avhandlingen:

Klebsiella pneumoniae is a bacterium able to cause infections in humans, especially in hospitalised patients. This species is often resistant to clinically important antibiotics, and infections can therefore be challenging to treat. In this work, we examined the prevalence of K. pneumoniae in samples of bivalve molluscs, fish, sediments, and seawater collected from the Norwegian marine environment. The results from this work shows that K. pneumoniae can be present in bivalves and seawater collected from coastal sources. A few of the isolates recovered from these sources were resistant to clinically relevant antibiotics and harboured genes that are associated with human infection. We also show that K. pneumoniae found in the Norwegian marine environment can resemble those found in clinical settings. This work highlights the potential of seafood and the marine environment to serve as vector for potentially disease-causing bacteria and antibiotic resistance to humans.
