  • a Data are compiled for strains belonging to the same species. The partial gdh gene sequences are all 431 bp in length.

  • b The gdh sequences of strains SSI 220/202, SK155, and SK610 and type strain CCUG24891 were achieved in our laboratory. The gdh sequences of strains SK100, SK152, SK555, SK394, SK570, SK573, and SK580 were downloaded from M. Kilian's website (www.immi.au.dk/service/download/kilian ).
