[Identification of hypervariable regions within the 16S-23S rRNA intergenic spacer region of Flavobacterium columnare and its application in assigning genomovar group to an individual strain].

Abstract excerpt

Flavobacterium columnare is an important bacterial pathogen of fish with wide ge- netic variability within species. This intraspecies diversity has been termed as genomovars and genomovar groups on the basis of Restriction Fragment Length Polymorphisms of 16S rDNA and 16S-23S rDNA Intergenic Spacer Region (ISR), respectively. In this study, we demonstrate the source of genetic heterogeneity in the F. columnare by...
