[Deoxyribonucleic acid hybridizations among some vibrio-like marine bacteria (author's transl)]

The genotypic relationships established by DNA/DNA hybridization in vitro confirm the results obtained by earlier phenotypic analyses of certain vibrio-like marine bacteria. These strains are closely related to the species Photobacterium fischeri, and do not belong to the genus Vibrio. The group of marine, vibrio-like bacteria that require Na+ for growth is genotypically very heterogeneous.
