A strain of lactic acid bacteria, designated 159469T, isolated from a facial abscess in a sugar glider, was characterized genetically and phenotypically. Cells of the strain were Gram-stain-positive, coccoid and catalase-negative. Morphological, physiological and phylogenetic data indicated that the isolate belongs to the genus Lactococcus. Strain 159469T was closely related to Lactococcus garvieae ATCC 43921T, showing 95.86 and 98.08 % sequence similarity in 16S rRNA gene and rpoB gene sequences, respectively. Furthermore, a pairwise average nucleotide identity blast (ANIb) value of 93.54 % and in silico DNA-DNA hybridization value of 50.7  % were determined for the genome of strain 159469T, when compared with the genome of the type strain of Lactococcus garvieae. Based on the data presented here, the isolate represents a novel species of the genus Lactococcus, for which the name Lactococcus petauri sp. nov. is proposed. The type strain is 159469T (=LMG 30040T=DSM 104842T).
