title: Relationships among Vibrio costicola strains assessed by DNA-DNA hybridization.
abstract: Deoxyribonucleic acid (DNA)-DNA hybridization was used to determine the relationships among 14 strains of Vibrio costicola isolated from cured meats or hypersaline waters. Our results indicate that the strains investigated should be considered members of the same genomic species, with homologies of 60% or higher with the V. costicola strains used as reference. Low DNA relatedness was found with other marine vibrios or moderately halophilic bacteria tested. The guanine-plus-cytosine base contents of DNAs from the 14 V. costicola strains were 47.6 to 51.1 mol%.
