Lactococcus petauri sp. nov., isolated from an abscess of a sugar glider

Abstract

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).

Genome Sequences of Lactococcus garvieae and Lactococcus petauri Strains Isolated from Traditional Montenegrin Brine Cheeses

“… L. garvieae was first described as Streptococcus garvieae in 1983 ( 1 ) and subsequently separated into subgroups A and B ( 2 ). Genomic analysis reassigned L. garvieae subgroup A strains to the recently described species L. petauri ( 3 ). Consequently, both species can be considered the etiological agents of lactococcosis in fish ( 4 , 5 ) and emerging opportunistic zoonotic pathogens ( 6 – 8 ).…”

Complete genome sequence and probiotic properties of Lactococcus petauri LZys1 isolated from healthy human gut

“…As a new feed additive, Lactococcus can optimize the structure of intestinal flora and promote the growth of mice. Lactococcus petauri is facultative anaerobic, non-motile, non-spore forming, and Gram-positive [13]. Yet there are few probiotic functional pieces of evidence of Lactococcus petauri published as mostly probiotics have strains specific properties [14].…”

Complete Genome Insights into Lactococcus petauri CF11 Isolated from a Healthy Human Gut Using Second- and Third-Generation Sequencing

“…It is found that Lactococcus lactis was present in the gastrointestinal tract of the infant on the first day of the life (Park et al, 2005). Lactococcus petauri has the closest relationship with L. garvieae and is a facultative anaerobic, non-motile, non-spore forming, Grampositive cocci (Goodman et al, 2017). To date, L. petauri has been obtained in a facial abscess of a sugar glider alone, and no functional evidence was published.…”
