Comparison of the 23S rRNA gene sequences of Edwardsiella tarda and Edw. ictaluri confirmed a close phylogenetic relationship between these two fish pathogen species and a distant relation with the 'core' members of the Enterobacteriaceae family. Analysis of the rrl gene for 23S rRNA in Edw. ictaluri revealed the presence of an intervening sequence (IVS) in helix-45. This new 98bp IVS shared 97% nucleotide identity with Salmonella typhimurium helix-45 IVS. Edw. ictaluri helix-45 IVS was present… CONTINUE READING
