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

Abstract

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. Phenotypic analysis involved using MALDI-TOF MS and BIOLOG GEN III microplates, which confirmed that the isolates represented members of the genus but did not allow them to be classified with respect to species. Genome relatedness indices and the results of extensive phylogenetic analysis confirmed that the isolates were members of the genus and represented a novel species. On the basis the minimal presence of virulence-associated factors typically found in genomes of members of the genus , we suggest that these isolates are non-pathogenic. This conclusion was supported by the results of a pathogenicity assay. On the basis of these findings, we propose the name , with DAR 34855 = ICMP 24941 as the type strain.
