Abstract
Seventeen flavobacteria, including 12 strains of Flavobacterium meningosepticum, were investigated to determine their genetic relationships by deoxyribonucleic acid (DNA)-DNA hybridization and guanine plus cytosine content. The percentage of binding among the strains tested ranged from 6 to 87%. There was no correlation between the serotype and DNA-duplex formation. The guanine plux cytosine content of the representative strains of the five serotypes ranged from 31 to 50%.
