Sundell, From genotype to phenotype - Diversity and population structure of Flavobacterium psychrophilum

This thesis integrates the tools of molecular genetics and conventional phenotypic microbiology to bring increased knowledge about the diversity and population structure of the fish pathogenic bacterium Flavobacterium psychrophilum. This work shows that the pathogen has an epidemic structure dominated by one particular globally distributed genetic lineage containing specific genotypes associated with high mortalities in economically important salmonid fish species. The simultaneous presence of...
