Abstract
During our studies on spoilage microbiomes of modified atmosphere packaged broiler meat, we isolated three strains (PNs007T, STAA11T and STAA25) of unknown identity. In this present polyphasic taxonomy study, including genome-based analyses, we discovered that these isolates represent two novel species belonging to the genus Vagococcus. In all phylogenetic analyses, PNs007T was positioned very close to Vagococcus fessus but both the average nucleotide identity (ANI; 89.5 %) and digital DNA-DNA hybridization (dDDH; 38.3 %) values distinguished it as a novel vagococcal species. STAA11T and STAA25 were genetically highly similar (16S rRNA, ANI and dDDH 100 %). The phylogenetic position of STAA11T was adjacent to but out of the cluster containing V. fessus, Vagococcus coleopterorum and PNs007T. According to the ANI (76.2-76.4 %) and dDDH (<22.6 %) values it also represented a novel vagococcal species. Phenotypic characteristics and chemotaxonomic properties of both novel species were typical for vagococci and they contained C16 : 0 (25.5-30.1 %) and C18 : 1 ω9c (67.3-73.0 %) as the major cellular fatty acids. The streptomycin-resistant genotype of STAA11T and STAA25 allowing the growth on streptomycin thallous acetate actidione medium was considered to result from a modification in codon 104 of the rpsL gene leading to P104A substitution. The ability of STAA11T and STAA25 to produce ammonia from arginine separated them from PNs007T, which did not show arginine deiminase activity. We propose the names Vagococcus proximus sp. nov. (type strain PNs007T=DSM 115185T=CCUG 76696T) and Vagococcus intermedius sp. nov. (type strain STAA11T=DSM 115183T=CCUG 76697T) for these novel species.

Abstract
The taxonomic positions of two novel strains isolated from larvae of an insect (Allomyrina dichotoma) collected in Jeju, Republic of Korea, were determined by a polyphasic approach. Strain BWB3-3T was closely related to the type strain of
Vagococcus salmoninarum
, having 97.2 % 16S rRNA gene sequence similarity, whereas strain BWM-S5T formed an independent cluster within the genus
Enterococcus
in the 16S rRNA gene phylogeny and the closest relative was the type strain of
Enterococcus canis
(98.1 % sequence similarity). The core gene analysis supported the phylogenetic positions of the isolates revealed by 16S rRNA gene phylogeny. The average nucleotide identity (ANI) and digital DNA–DNA hybridization (dDDH) values between strain BWB3-3T and the type strain of
V. salmoninarum
were 73.2 and 20.0 %, respectively, whereas strain BWM-S5 T showed an ANI value of 70.9 % with the type strain of
Enterococcus canis
. The dDDH values between strain BWM-S5T and all the type strains of
Enterococcus
species were ≤25.1 %. On the basis of the results obtained here, the two isolates are considered to constitute two novel species of the family
Enterococcaceae
, for which the names Vagococcus allomyrineae sp. nov. and Enterococcus larvae sp. nov. are proposed, with the type strains BWB3-3T (=KCTC 43277T=CCM 9080T) and BWM-S5T (=KACC 22156T=CCM 9075T), respectively.

Description of Vagococcus coleopterorum sp. nov., isolated from the intestine of the diving beetle, Cybister lewisianus, and Vagococcus hydrophili sp. nov., isolated from the intestine of the dark diving beetle, Hydrophilus acuminatus, and emended description of the genus Vagococcus. J Microbiol 2020; 59:132-141. [PMID: 33355892 DOI: 10.1007/s12275-021-0485-1] [Citation(s) in RCA: 12] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/21/2020] [Revised: 11/19/2020] [Accepted: 11/23/2020] [Indexed: 01/20/2023]
Abstract
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 C18:1ω9c as the major cellular fatty acids, but C16:1ω9c 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).

Vagococcus zengguangii sp. nov., isolated from yak faeces. J Microbiol 2020; 59:1-9. [PMID: 33355894 DOI: 10.1007/s12275-021-0406-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/03/2020] [Revised: 10/27/2020] [Accepted: 11/11/2020] [Indexed: 10/22/2022]
Abstract
Two unknown Gram-stain-positive, catalase- and oxidasenegative, non-motile, and coccus-shaped bacteria, designated MN-17T and MN-09, were isolated from yaks faeces (Bos grunniens) in the Qinghai-Tibet Plateau of China. 16S rRNA gene sequence-based comparative analyses revealed that the two strains were grouped within the genus Vagococcus, displaying the highest similarity with Vagococcus xieshaowenii CGMCC 1.16436T (98.6%) and Vagococcus elongatus CCUG 51432T (96.4%). Both strains grew optimally at 37°C and pH 7.0 in the presence of 0.5% (w/v) NaCl. The complete genome of MN-17T comprises 2,085 putative genes with a total of 2,190,262 bp and an average G + C content of 36.7 mol%. The major fatty acids were C16:0 (31.2%), C14:0 (28.5%), and C18:1ω9c (13.0%); the predominant respiratory quinone was MK-7 (68.8%); the peptidoglycan type was A4α(L-Lys-D-Asp); and the major polar lipid was diphosphatidylglycerol. Together, these supported the affiliation of strain MN-17T to the genus Vagococcus. In silico DNA-DNA hybridization and the average nucleotide identity values between MN-17T and all recognized species in the genus were 21.6-26.1% and 70.7-83.0%, respectively. MN-17T produced acid from D-cellobiose, D-fructose, glycerol, D-glucose, N-acetyl-glucosamine, gentiobiose, D-mannose, D-maltose, D-ribose, D-saccharose, salicin, D-trehalose, and D-xylose. These results distinguished MN-17T and MN-09 from closely related species in Vagococcus. Thus, we propose that strains MN-17T and MN-09 represent a novel species in the genus Vagococcus, with the name Vagococcus zengguangii sp. The type strain is MN-17T (= CGMCC 1.16726T = GDMCC 1.1589T = JCM 33478T).

Vagococcus fluvialis as a causative pathogen of bloodstream and decubitus ulcer infection: Case report and systematic review of the literature. J Infect Chemother 2020; 27:359-363.

Abstract
BACKGROUND Vagococcal infections are uncommon in humans; there are limited studies on the clinical manifestations, the optimal methods for identifications, and antimicrobial susceptibility testing for vagococcal infections. Here, we have reported a case of Vagococcus fluvialis-induced bacteremia and decubitus ulcer and have systematically reviewed other reported Vagococcus infections. CASE PRESENTATION A 74-year-old man presented to our emergency department with muscle weakness on his left extremities, dysarthria, and altered mental status along with fever for the past 4 days. Physical examination revealed a decubitus ulcer with foul smelling and yellowish exudative pus on his left chest wall and abdomen, forearm, thigh, and lower leg. He was empirically treated with 2.25 mg of piperacillin/tazobactam every 8 hours and 0.5 g of vancomycin every 24 hours intravenously (IV) for his decubitus ulcer. Vagococcus fluvialis was detected in both aerobic and anaerobic blood cultures (upon admission) using the VITEC 2 GP ID card (bioMérieux) and matrix-assisted laser desorption/ionization-time-of-flight mass spectrometry (MALDI-TOF MS). We continued the mentioned IV antimicrobial therapies for 4 weeks following which the patient was transferred to a long-term care facility for further rehabilitation. CONCLUSIONS To our best knowledge, this is the first literature review of Vagococcus infections in humans. Since it is challenging to distinguish Vagococcus from Enterococcus by a conventional method due to the similarity of its biochemical properties to those of Enterococcus, based on our literature review, 16S rRNA sequencing or analysis of bacterial protein profile using MALDI-TOF MS may be useful for the precise identification.

Abstract
A Gram-stain-positive, coccus- or oval-shaped, non-motile, haemolytic, asporogenous, catalase- and oxidase-negative, and facultatively anaerobic strain, 2B-2T, was isolated from a brewer's grain used to make silage in Taiwan. Comparative analyses of 16S rRNA, hsp60 and pheS gene sequences demonstrated that strain 2B-2T was a member of the genus Vagococcus. On the basis of 16S rRNA gene sequence similarity, the type strains of Vagococcus teuberi (98.4 % similarity), Vagococcus carniphilus (98.4 %), Vagococcus martis (98.2 %), Vagococcus penaei (98.2 %) and Vagococcus fluvialis (98.0 %) were the closest neighbours to this novel strain. The similarity levels of concatenated housekeeping gene sequences (hsp60 and pheS) between strain 2B-2T and these closely related species ranged from 84.5 to 88.0 %. The average nucleotide identity and in silico DNA-DNA hybridization values between strain 2B-2T and its closest relatives were lower than 72.9 and 21.6 %, respectively. The DNA G+C content was 34.7 mol%. Phenotypic and genotypic features demonstrated that strain 2B-2T represents a novel species of the genus Vagococcus, for which the name Vagococcus silagei sp. nov. is proposed. The type strain is 2B-2T (=BCRC 81132T=NBRC 113536T).

Abstract
A Gram-stain-positive, coccus-shaped, non-motile bacterium, designated CF-49T, was isolated from the cloacal content of a snow finch, which was incidentally captured in a plateau pika burrow on the Qinghai-Tibet Plateau, PR China. Analysis of the 16S rRNA gene sequence showed that strain CF-49T was closely related to Vagococcus elongatus CCUG 51432T (96.5 % similarity), Vagococcus fluvialis NCFB 2497T (96.0 %) and Vagococcus lutrae CCUG 39187T (95.9 %), whereas the similarity to another isolate (CF-210) was 99.9 %. Strains CF-49T and CF-210 grew optimally at 37 °C and pH 7.0 and in the presence of 0.5 % (w/v) NaCl. Acid was produced from N-acetylglucosamine, cellobiose, d-fructose, d-glucose, d-mannose, d-mannitol, maltose, d-ribose and salicin. The cell-wall peptidoglycan type was A4α (l-Lys-d-Asp). The major cellular fatty acids (>10 %) were C16 : 0 (35.6 %), C14 : 0 (17.3 %), C18 : 1 ω9c (16.2 %) and C16 : 1 ω9c (10.6 %). The predominant respiratory quinone was menaquinone MK-7 (68.8 %). The G+C content of the genomic DNA was 35.9 mol%. Digital DNA-DNA hybridization of strain CF-49T with V. fluvialis DSM 5731T, V. elongatus CCUG 51432Tand V. lutrae CCUG 39187T resulted in relatedness values of 21.4, 23.3 and 24.6 %, respectively. Based on results from polyphasic analyses, our two isolates are proposed to represent a novel species in the genus Vagococcus, with the name Vagococcus xieshaowenii. The type strain is CF-49T (=CGMCC 1.6436T=GDMCC 1.1588T=JCM 33477T).

Abstract
Two unusual catalase-negative, Gram-stain-positive, Vagococcus-like isolates that were referred to the CDC Streptococcus Laboratory for identification are described. Strain SS1994T was isolated from ground beef and strain SS1995T was isolated from a human foot wound. Comparative 16S rRNA gene sequence analysis of isolates SS1994T and SS1995T against Vagococcus type strain sequences supported their inclusion in the genus Vagococcus. Strain SS1994T showed high sequence similarity (>97.0 %) to the two most recently proposed species, Vagococcus martis (99.2 %) and Vagococcus teuberi (99.0 %) followed by Vagococcus penaei (98.8 %), strain SS1995T (98.6 %), Vagococcus carniphilus (98.0 %), Vagococcus acidifermentans (98.0 %) and Vagococcus fluvialis (97.9 %). The 16S rRNA gene sequence of strain SS1995T was most similar to V. penaei (99.1 %), followed by SS1994T (98.6 %), V. martis (98.4 %), V. teuberi (98.1 %), V. acidifermentans (97.8 %), and both V. carniphilus and V. fluvialis (97.5 %). A polyphasic taxonomic study using conventional biochemical and the rapid ID 32 STREP system, MALDI-TOF MS, cell fatty acid analysis, pairwise sequence comparisons of the 16S rRNA, rpoA, rpoB, pheS and groL genes, and comparative core and whole genome sequence analyses revealed that strains SS1994T and SS1995T were two novel Vagococcus species. The novel taxonomic status of the two isolates was confirmed with core genome phylogeny, average nucleotide identity <84 % and in silico DNA-DNA hybridization <28 % to any other Vagococcus species. The names Vagococcusbubulae SS1994T=(CCUG 70831T=LMG 30164T) and Vagococcusvulneris SS1995T=(CCUG 70832T=LMG 30165T) are proposed.

Abstract
Three unknown Gram-stain-positive, catalase-negative, facultatively anaerobic and coccus-shaped strains of bacteria were isolated from the digestive tracts of wasps (Vespula vulgaris). Analysis of 16S rRNA gene sequences revealed that these strains had identical sequences and showed that
Vagococcus salmoninarum
, with 96.2 % sequence similarity, was the closest phylogenetic neighbour. Further analyses based on hsp60 and pheS gene sequences of representatives of the family Enteroccocaceae and genotypic and phenotypic characterization using (GTG)5-PCR fingerprintings, EcoRI ribotyping, DNA G+C content, whole-cell protein profiling, cellular fatty acid profiles analysis and extensive biotyping confirmed that the investigated strains were representatives of a novel bacterial species within the genus Vagoccocus for which the name Vagoccocus entomophilus sp. nov. is proposed. The type strain is VOSTP2T ( = DSM 24756T = CCM 7946T).

Abstract
Vagococci are usually isolated from marine hosts and occasionally from endodontic infections. Using 16S rRNA gene comparison, the closest relatives are members of the genera Enterococcus and Carnobacterium. A draft sequence of Vagococcus lutrae was generated to clarify the relationship of Vagococcus to these and other related low-G+C Gram-positive bacteria.

Abstract
Marination with marinade containing salt, sugar, and acetic acid is commonly used in Finland to enhance the value of raw broiler meat. In this study, we investigated the effect of marination, marinade components and storage time on composition of bacterial communities in modified atmosphere-packaged (MAP) broiler fillet strips. The communities were characterized using two culture-independent methods: 16S rRNA gene fragment sequencing and terminal restriction fragment length polymorphism. In unmarinated broiler fillet strips, Lactococcus spp. and Carnobacterium spp. predominated at the early storage phase but were partially replaced by Lactobacillus spp. and Leuconostoc spp. when the chilled storage time was extended. In the marinated fillet strips, Lactobacillus spp. and Leuconostoc spp. predominated independent from the storage time. By mixing the different marinade components with broiler meat, we showed that marination changed the community composition and favored Leuconostoc spp. and Lactobacillus spp. by the combined effect of carbohydrates and acetic acid in marinade. Marination increased the maximum level of lactic acid bacteria in broiler meat and enhanced CO2 production and acidification of meat during the chilled storage. Accumulation of CO2 in package head-space due to the enhanced growth of Leuconostoc spp. in marinated meat may lead to bulging of packages, which is a spoilage defect frequently associated with marinated and MAP raw broiler preparations in Finland.

Abstract
Ninety-seven animal, human, and dairy Streptococcus porcinus or Streptococcus pseudoporcinus isolates in the CDC Streptococcus strain collection were evaluated on the basis of DNA-DNA reassociation, 16S rRNA and rpoB gene sequencing, conventional biochemical and Rapid ID 32 Strep identification methods, and antimicrobial susceptibility testing to determine their taxonomic status, characteristics for species differentiation, antimicrobial susceptibility, and relevance of clinical source. Nineteen of the 97 isolates (1 human, 18 swine) were identified as S. porcinus. The remaining 72 human isolates and 6 dairy isolates were identified as S. pseudoporcinus. The use of 16S rRNA or rpoB gene sequencing was required to differentiate S. porcinus from S. pseudoporcinus. The human and dairy S. pseudoporcinus isolates were biochemically distinct from each other as well as distinct by 16S rRNA and rpoB gene sequencing. Therefore, we propose the subspecies denominations S. pseudoporcinus subsp. hominis subsp. nov. for the human isolates and S. pseudoporcinus subsp. lactis subsp. nov. for the dairy isolates. Most strains were susceptible to the antimicrobials tested, with the exception of tetracycline. Two strains of each species were also resistant to clindamycin and erythromycin and carried the erm(A) (S. pseudoporcinus) or the erm(B) (S. porcinus) gene. S. porcinus was identified from a single human isolate recovered from a wound in an abattoir worker. S. pseudoporcinus was primarily isolated from the genitourinary tract of women but was also associated with blood, placental, and wound infections. Isolates reacting with group B antiserum and demonstrating wide beta-hemolysis should be suspected of being S. pseudoporcinus and not S. agalactiae.

Abstract
A Gram-staining-positive, coccus-shaped, non-spore-forming, facultatively anaerobic bacterium, designated AC-1T, was isolated from an acidogenic fermentation bioreactor treating food wastewater. On the basis of 16S rRNA gene sequence analysis, strain AC-1T was shown to belong to the genus Vagococcus. The closest phylogenetic relatives were Vagococcus elongatus PPC9T (97.4 % 16S rRNA gene sequence similarity), Vagococcus penaei CD276T (96.7 %) and Vagococcus carniphilus ATCC BAA-640T (96.6 %). The major fatty acids were C18 : 1ω9c (24.8 %) and C16 : 0 (19.5 %) and the G+C content of genomic DNA was 44.2 mol%, which supported the affiliation of strain AC-1T to the genus Vagococcus. Strain AC-1T and V. elongatus DSM 21480T exhibited 11 % DNA–DNA relatedness. Physiological and biochemical tests differentiated strain AC-1T from the type strains of recognized species of the genus Vagococcus. Therefore, strain AC-1T is considered to represent a novel species, for which the name Vagococcus acidifermentans sp. nov. is proposed. The type strain is AC-1T ( = KCTC 13418T = LMG 24798T).

Abstract
Aerobic, alkaliphilic bacteria were isolated and characterized from water and sediment samples collected in the winter season, January 2002 from alkaline Lonar lake, India, having pH 10.5. The total number of microorganisms in the sediment and water samples was found to be 10(2)-10(6) cfu g(-1) and 10(2)-10(4) cfu ml(-1), respectively. One hundred and ninety-six strains were isolated using different enrichment media. To study the bacterial diversity of Lonar lake and to select the bacterial strains for further characterization, screening was done on the basis of pH and salt tolerance of the isolates. Sixty-four isolates were subjected to phenotypic, biochemical characterization and 16S rRNA sequencing. Out of 64, 31 bacterial isolates were selected on the basis of their enzyme profile and further subjected to phylogenetic analysis. Phylogenetic analysis indicated that most of the Lonar lake isolates were related to the phylum Firmicutes, containing Low G+C, Gram-positive bacteria, with different genera: Bacillus, Paenibacillus, Alkalibacillus, Exiguobacterium, Planococcus, Enterococcus and Vagococcus. Seven strains constituted a Gram-negative bacterial group, with different genera: Halomonas, Stenotrophomonas and Providencia affiliated to gamma-Proteobacteria, Alcaligenes to beta-Proteobacteria and Paracoccus to alpha-Proteobacteria. Only five isolates were High G+C, Gram-positive bacteria associated with phylum Actinobacteria, with various genera: Cellulosimicrobium, Dietzia, Arthrobacter and Micrococcus. Despite the alkaline pH of the Lonar lake, most of the strains were alkalitolerant and only two strains were obligate alkaliphilic. Most of the isolates produced biotechnologically important enzymes at alkaline pH, while only two isolates (ARI 351 and ARI 341) showed the presence of polyhydroxyalkcanoate (PHA) and exopolysaccharide (EPS), respectively.

Abstract
Lactic acid bacteria have become a major source of concern for aquaculture in recent decades. In addition to true pathogenic species of worldwide significance, such as Streptococcus iniae and Lactococcus garvieae, several species have been reported to produce occasional fish mortalities in limited geographic areas, and many unidentifiable or ill-defined isolates are regularly isolated from fish or fish products. To clarify the nature and prevalence of different fish-associated bacteria belonging to the lactic acid bacterium group, a collection of 57 isolates of different origins was studied and compared with a set of 22 type strains, using amplified rRNA gene restriction analysis (ARDRA). Twelve distinct clusters were delineated on the basis of ARDRA profiles and were confirmed by sequencing of sodA and 16S rRNA genes. These clusters included the following: Lactococcus raffinolactis, L. garvieae, Lactococcus l., S. iniae, S. dysgalactiae, S. parauberis, S. agalactiae, Carnobacterium spp., the Enterococcus "faecium" group, a heterogeneous Enterococcus-like cluster comprising indiscernible representatives of Vagococcus fluvialis or the recently recognized V. carniphilus, V. salmoninarum, and Aerococcus spp. Interestingly, the L. lactis and L. raffinolactis clusters appeared to include many commensals of fish, so opportunistic infections caused by these species cannot be disregarded. The significance for fish populations and fish food processing of three or four genetic clusters of uncertain or complex definition, namely, Aerococcus and Enterococcus clusters, should be established more accurately.

Abstract
The National Antimicrobial Resistance Monitoring System Laboratory at the Centers for Disease Control and Prevention (CDC) isolated two enterococcus-like strains that were referred to the CDC Streptococcus Laboratory for further identification. The isolates were recovered from human stool samples collected on different occasions from the same individual in Portland (OR, USA) in July 2000. Conventional physiological tests distinguished these strains from all known species of enterococci. Analyses of whole-cell-protein electrophoretic profiles showed the same unique profile for the two isolates, being most similar those of Enterococcus moraviensis and Enterococcus haemoperoxidus albeit not close enough to allow conclusive inclusion in any enterococcal species. Both isolates gave positive results in tests using the AccuProbe Enterococcus genetic probe, and Lancefield extracts reacted with CDC group D antiserum. Comparative 16S rRNA gene sequencing studies also revealed that these strains were closely related to the species E. moraviensis (99.6 % identity). The results of DNA–DNA relatedness experiments confirmed that these strains represented a single novel taxon. The highest level of DNA–DNA relatedness found between the novel taxon and any of the currently recognized species of Enterococcus was 32 %, for both E. moraviensis and E. haemoperoxidus. On the basis of this evidence, it is proposed that these stool isolates constitute a novel species, for which the name Enterococcus caccae sp. nov. is proposed. The type strain is 2215-02T (=SS-1777T=ATCC BAA-1240T=CCUG 51564T).
