Abstract
The small subunit ribosomal RNA (SSU rRNA) encoding genes from reference strains of Aeromonas salmonicida subsp, smithia and Haemophilus piscium were amplified by polymerase chain reaction and cloned into Escherichia coli cells. Almost the entire SSU rRNA gene sequence (1505 nucleotides) from both organisms was determined. These DNA sequences were compared with those previously described from A. salmonicida subsp. salmonicida, subsp, achromogenes and subsp, masoucida. This genetic analysis revealed that A. salmonicida subsp, smithia and H. piscium showed 99.4 and 99.6% SSU rRNA gene sequence identity, respectively, with A. salmonicida subsp. salmonicida.
