| We have examined the 16S-23S rRNA intergenic spacer regions (ISR) of Vibrio fluvialis. ISRs were PCR amplified, cloned into a plasmid vector and then sequenced. As results of ISR nucleotide sequence analysis, total of 6 clones were isolated depending on the size. The clones were different in both the number and the composition of the tRNA genes, and were designated ISR-A, ISR-E, ISR-El, ISR-lA, ISR-EKV, ISR-EKAV. ISR-A contains $tRNA^{Ala}$; ISR-lA, $tRNA^{Ile}$-$tRNA^{Ala}$; ISR-EKV, $tRNA^{GIu}$-$tRNA^{Lys}$-$tRNA^{Val}$;ISE-EKAV, $tRNA^{GIu}$-$tRNA^{Lys}$-$tRNA^{Ala}$-$tRNA^{Val}$; ISR -E and E1, $tRNA^{GIu}$ clusters. ISR-EKV was shown to be a minor type out of the six ISR types and showed a very limited homology between ISR-EKV from V, fluvialis and ISRa from other Vibrio species. Therefore ISR-EKV sequence was used to design species-specific primers to detect V, fiuvialis from other Vibrio species by PCR reaction. The specificity of the primers was examined using genomic DNA of other Vibrios as templates for PCR reaction. The result showed that PCR can be a useful method to detect V. fluvialis among Vibrio species in a single PCR reaction. |
