Molecular diversity of strains isolated from .

bacterium is known to be the causative agent of American foulbrood (AFB), a widespread, highly contagious and fatal disease in honey bees (). There are four genotypes of that are named after their enterobacterial repetitive consensus (ERIC), and a fifth ERIC genotype has recently been found. In this study, a total of 108 independent isolates from different geographical regions in Lithuania collected between 2011 and 2021 were investigated by molecular methods.
