Three aerobic, Gram-negative, and rod-shaped bacterial strains,
designated strains G4M1T, SM13T, and L12M9T, were isolated
from the gut of Batillaria multiformis, Cellana toreuma, and
Patinopecten yessoensis collected from the Yellow Sea in South
Korea. All the strains grew optimally at 25°C, in the presence
of 2% (w/v) NaCl, and at pH 7. These three strains, which
belonged to the genus Polaribacter in the family Flavobacteriaceae,
shared < 98.8% in 16S rRNA gene sequence and < 86.68%
in whole-genome sequence with each other. Compared with
the type strains of Polaribacter, isolates showed the highest
sequence similarity to P. haliotis KCTC 52418T (< 98.68%),
followed by P. litorisediminis KCTC 52500T (< 98.13%). All
the strains contained MK-6 as their predominant menaquinone
and iso-C15:0 as their major fatty acid. Moreover, all the
strains had phosphatidylethanolamine as their polar lipid
component. In addition, strain G4M1T had two unidentified
lipids and three unidentified aminolipids, strain SM13T had
three unidentified lipids and three unidentified aminolipids,
and strain L12M9T had three unidentified lipids and one unidentified
aminolipid. The DNA G + C contents of strains
G4M1T, SM13T, and L12M9T were 31.0, 30.4, and 29.7 mol%,
respectively. Based on phenotypic, phylogenetic, chemotaxonomic,
and genotypic findings, strains G4M1T (= KCTC 82388T
= DSM 112372T), SM13T (= KCTC 82389T = DSM 112373T),
and L12M9T (= KCTC 62751T = DSM 112374T) were classified
into the genus Polaribacter as the type strains of novel
species, for which the names Polaribacter batillariae sp. nov.,
Polaribacter cellanae sp. nov., and Polaribacter pectinis sp.
nov., respectively, have been proposed.

Abstract
PDF
-
Phenotypic and genomic analyses were performed to characterize
two novel species, H23M54T and AMA3305T, isolated
from the faeces of the Oriental stork (Ciconia boyciana) and
the cinereous vulture (Aegypius monachus), respectively. Strains
H23M54T and AMA3305T showed the highest similarities of
16S rRNA gene sequences and complete genome sequences
with Ornithinimicrobium cavernae CFH 30183T (98.5% of 16S
rRNA gene sequence similarity and 82.1% of average nucleotide
identity, ANI) and O. pekingense DSM 21552T (98.5% of
16S rRNA gene sequence similarity and 82.3% of ANI), respectively.
Both strains were Gram-stain-positive, obligate aerobes,
non-motile, non-spore-forming, and coccoid- and rodshaped.
Strain H23M54T grew optimally at 25–30°C and pH
8.0 and in the presence of 1.5–2% (wt/vol) NaCl, while strain
AMA3305T grew optimally at 30°C and pH 7.0 and in the presence
of 1–3% (wt/vol) NaCl. Both strains had iso-C15:0, iso-
C16:0, and summed feature 9 (iso-C17:1 ω9c and/or C16:0 10-
methyl) as major cellular fatty acids. MK-8 (H4) was identified
as the primary respiratory quinone in both strains. Strains
H23M54T and AMA3305T possessed diphosphatidylglycerol
and phosphatidylglycerol as major polar lipids. Moreover,
strains H23M54T and AMA3305T commonly contained ribose
and glucose as major sugars and L-ornithine, L-alanine,
glycine, and aspartic acid as major amino acids. The polyphasic
taxonomic data indicate that strains H23M54T and AMA3305T
represent novel species of the genus Ornithinimicrobium. We
propose the names Ornithinimicrobium ciconiae sp. nov. and
Ornithinimicrobium avium sp. nov. for strains H23M54T (= KCTC 49151T = JCM 33221T) and AMA3305T (= KCTC
49180T = JCM 32873T), respectively.

Abstract

Viridans group streptococci are a serious health concern because
most of these bacteria cause life-threatening infections,
especially in immunocompromised and hospitalized individuals.
We focused on two alpha-hemolytic Streptococcus
strains (I-G2 and I-P16) newly isolated from an ileostomy
effluent of a colorectal cancer patient. We examined their pathogenic
potential by investigating their prevalence in human
and assessing their pathogenicity in a mouse model. We also
predicted their virulence factors and pathogenic features by
using comparative genomic analysis and in vitro tests. Using
polyphasic and systematic approaches, we identified the isolates
as belonging to a novel Streptococcus species and designated
it as Streptococcus ilei. Metagenomic survey based on
taxonomic assignment of datasets from the Human Microbiome
Project revealed that S. ilei is present in most human
population and at various body sites but is especially abundant
in the oral cavity. Intraperitoneal injection of S. ilei was
lethal to otherwise healthy C57BL/6J mice. Pathogenomics
and in vitro assays revealed that S. ilei possesses a unique set
of virulence factors. In agreement with the in vivo and in vitro
data, which indicated that S. ilei strain I-G2 is more pathogenic
than strain I-P16, only the former displayed the streptococcal
group A antigen. We here newly identified S. ilei sp.
nov., and described its prevalence in human, virulence factors,
and pathogenicity. This will help to prevent S. ilei strain
misidentification in the future, and improve the understanding
and management of streptococcal infections.

Abstract
PDF

A polyphasic taxonomic approach was used to characterize
two novel bacterial strains, HDW17AT and HDW17BT, isolated
from the intestine of the diving beetle Cybister lewisianus,
and the dark diving beetle Hydrophilus acuminatus,
respectively. Both strains were Gram-positive and facultative
anaerobic cocci forming cream-colored colonies. The isolates
grew optimally at 25°C, pH 7, in the presence of 0.3% (wt/vol)
NaCl. Phylogenetic analysis based on 16S rRNA gene sequences
and genome sequences showed that the isolates were
members of the genus Vagococcus, and strain HDW17AT was
closely related to Vagococcus fessus CCUG 41755T (98.9% of
16S rRNA gene sequence similarity and 74.3% of average
nucleotide identity [ANI]), whereas strain HDW17BT was
closely related to Vagococcus fluvialis NCFB 2497T (98.9% of
16S rRNA gene sequence similarity and 76.6% of ANI). Both
strains contained C16:0, and C18:1 ω9c as the major cellular fatty
acids, but C16:1 ω9c was also observed only in strain HDW17BT
as the major cellular fatty acid. The respiratory quinone of the
isolates was MK-7. The major polar lipid components were
phosphatidylglycerol, phosphatidylethanolamine, and diphosphatidylglycerol.
The genomic DNA G + C content of strains
HDW17AT and HDW17BT were 36.6 and 34.4%, respectively.
Both strains had cell wall peptidoglycan composed of the
amino acids L-alanine, glycine, D-glutamic acid, L-tryptophan,
L-lysine, and L-aspartic acid, and the sugars ribose, glucose,
and galactose. Based on phylogenetic, phenotypic, chemotaxonomic,
and genotypic analyses, strains HDW17AT and
HDW17BT represent two novel species in the genus Vagococcus.
We propose the name Vagococcus coleopterorum sp.
nov. for strain HDW17AT (= KACC 21348T = KCTC 49324T
= JCM 33674T) and the name Vagococcus hydrophili sp. nov.
for strain HDW17BT (= KACC 21349T = KCTC 49325T =
JCM 33675T).
