sp. nov., sp. nov. and sp. nov.: three members of group 1 .

Between 1976 and 2010, four bacterial isolates were collected in New South Wales and Queensland, Australia, and stored as part of routine biosecurity surveillance. Recently, these historic isolates were analysed as part of a larger project to enhance the taxonomic accuracy of our culture collection and improve Australia's biosecurity preparedness. Three isolates were collected from , initially identified as sp.

sp. nov., a non-pathogenic member of Group 1 .

Five bacterial isolates were isolated from in 1976 in Rydalmere, Australia, during routine biosecurity surveillance. Initially, the results of biochemical characterisation indicated that these isolates represented members of the genus . To determine their species, further analysis was conducted using both phenotypic and genotypic approaches.
