Molecular epidemiology of a nationwide Pseudomonas aeruginosa outbreak in Norway reveals multiple distinct clusters, including high-risk clone ST244
This comprehensive genomic surveillance study uncovered multiple unexpected clusters of P. aeruginosa bacteraemia isolates in Norway, along with widespread presence of susceptible epidemic clones. Routine multi-level surveillance integrating sequencing with epidemiological data could enable earlier recognition of emerging high-risk clones and outbreaks, thereby strengthening infection prevention efforts.
