We previously showed that both high-mobility group box-1 (HMGB1) and natural killer (NK) cells contribute to respiratory syncytial virus (RSV)-induced persistent airway inflammation and airway hyperresponsiveness (AHR). Meanwhile, Chemokine (C-X-C motif) ligand 12 (CXCL12) and its specific receptor (chemokine receptor 4, CXCR4) play important roles in recruitment of immune cells. CXCL12 has been reported to form a complex with HMGB1 that binds to CXCR4 and increases inflammatory cell migration. The relationship between HMGB1, NK cells and chemokines in RSV-infected model remains unclear. An anti-HMGB1 neutralizing antibody and inhibitor of CXCR4 (AMD3100) was administered to observe changes of NK cells and airway disorders in nude mice and BALB/c mice. Results showed that the mRNA expression and protein levels of HMGB1 were elevated in late stage of RSV infection and persistent airway inflammation and AHR were diminished after administration of anti-HMGB1 antibodies, with an associated significant decrease in CXCR4+ NK cells. In addition, CXCL12 and CXCR4 were reduced after HMGB1 blockade. Treatment with AMD3100 significantly suppressed the recruitment of NK cells and alleviated the airway disorders. Thus, CXCL12/CXCR4 axis is involved in the recruitment of NK cells by HMGB1, contributing to persistent airway inflammation and AHR during the late stage of RSV infection.

Abstract

CatR, a peroxide-sensing transcriptional repressor of Fur family, can de-repress the transcription of the catA gene encoding catalase upon peroxide stress in Streptomyces coelicolor. Since CatR-regulated genes other than catA and its own gene catR have not been identified in detail, the understanding of the role of CatR regulon is very limited. In this study, we performed transcriptomic analysis to identify genes influenced by both 􀈟􀂊atR mutation and hydrogen peroxide treatment. Through ChIP-qPCR and other analyses, a new consensus sequence was found in CatR-responsive promoter region of catR gene and catA operon for direct regulation. In addition, vtlA (SCO2027) and SCO4983 were identified as new members of the CatR regulon. Expression levels of iron uptake genes were reduced by hydrogen peroxide and a DmdR1 binding sequence was identified in promoters of these genes. The increase in free iron by hydrogen peroxide was thought to suppress the iron import system by DmdR1. A putative exporter protein VtlA regulated by CatR appeared to reduce intracellular iron to prevent oxidative stress. The name vtlA (VIT1-like transporter) was proposed for iron homeostasis related gene SCO2027.

Abstract

A yellow pigmented, Gram-stain-negative, strictly aerobic, rod-shaped, motile by means of gliding, catalase and oxidase positive bacterium, designated strain DS2-AT, was isolated from soil. Growth was observed at 4–32°C (optimum, 28°C), pH 6–9 (optimum, 7.0), and with 0–0.25% (w/v) NaCl (optimum, 0%). Phylogenetic analysis of 16S rRNA gene sequence revealed that strain DS2-AT belonged to the genus Flavobacterium and was most closely related to Flavobacterium aquatile LMG 4008T (96.4%), Flavobacterium terrae DSM 18829T (95.6%), Flavobacterium vireti THG-SM1T (95.5%), Flavobacterium inkyongense IMCC27201T (95.4%), Flavobacterium brevivitae TTM-43T (95.2%), and Flavobacterium cucumis DSM 18830T (95.2%). Strain DS2-AT produces flexirubin- type pigments. The major fatty acids were iso-C15:0, iso-C17:0 3-OH, and iso-C15:0 3-OH. The major respiratory quinone was identified as menaquinone-6. The major polar lipid was found to be phosphatidylethanolamine. The average nucleotide identity values between strain DS2-AT and selected taxa, F. aquatile LMG 4008T, F. terrae DSM 18829T, and F. cucumis DSM 18830T, were 72, 72.7, and 71.6%, respectively. The draft genome of strain DS2-AT has a number of 14 contigs, scaffold N50 of 476,310 bp and a total size of 3,563,867 bp. Additionally, strain DS2-AT contains 3,127 of gene, 41 of tRNA, 6 of rRNA, and 3 of ncRNA. The DNA G + C content of stain DS2-AT was 40.7 mol%. Based on phylogenetic and phenotypic analyses, strain DS2-AT is considered as a novel species of the genus Flavobacterium, for which the name Flavobacterium humi sp. nov., (type strain DS2-AT = KACC 19715T = JCM 32786T) has been proposed.

Abstract

A yellow pigmented, Gram-stain-negative, aerobic bacterium designated A5.7T was studied to evaluate the taxonomic position following the modern polyphasic approach. The strain was isolated from sediments near Zhairuo Island, which is situated in the East China Sea. Cells were non-spore forming rods without flagella but showed motility by gliding. Growth was observed at 15–35°C (optimum 28°C), pH 6.0–9.0 (optimum pH 6.5) and 0–2% (w/v) NaCl (optimum 0–0.5%) in LB broth. The major respiratory quinone of A5.7T was menaquinone 6. The major polar lipid of A5.7T was phosphatidylethanolamine and the predominant fatty acids (> 5%) were iso-C15:0, iso-C17:0 3-OH, C15:1 ω6c, iso-C15:0 3-OH, iso-C15:1 G, summed feature 3 (C16:1 ω7c and/or C16:1 ω6c) and summed feature 9 (iso-C17:1 ω9c and/or C16:0 10-methyl). Phylogenetic analysis based on 16S rRNA gene sequences showed that the isolate belongs to the genus Flavobacterium and shares the highest sequence similarities with Flavobacterium sharifuzzamanii A7.6T (98.5%), Flavobacterium tistrianum GB 56.1T (98.3%), Flavobacterium nitrogenifigens NXU-44T (97.8%), Flavobacterium anhuiense D3T (97.6%), Flavobacterium ginsenosidimutans THG 01T (97.6%), and Flavobacterium foetidum CJ42T (97.6%). Digital DNA-DNA hybridization and average nucleotide identity values between the strain and its closest phylogenetic neighbors showed the ranges from 19.6 to 34.1% and 73.7 to 87.9%, respectively. Therefore, based on polyphasic characteristics, strain A5.7T represents a novel species of the genus Flavobacterium for which the name Flavobacterium zhairuonensis sp. nov. is proposed. The type strain is A5.7T (= KCTC 62406T = MCCC 1K03494T).

Abstract

A non-motile, yellow-pigmented bacterial strain, designated IMCC34762T, was isolated from a freshwater sample collected from Lake Cheongpyeong in Korea. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain IMCC- 34762T formed a lineage within the genus Flavobacterium and was most closely related to F. pectinovorum DSM 6368T (98.3% sequence similarity), followed by F. piscis CCUG 60099T (98.3%), F. branchiicola 59B-3-09T (98.2%), and F. saccharophilum DSM 1811T (98.2%). The average nucleotide identity and the genome-to-genome distance between strain IMCC34762T and the closely related strains were 61–62% and 26–27%, respectively, indicating that IMCC34762T is a novel species of the genus Flavobacterium. The major fatty acids (> 5%) of strain IMCC34762T were summed feature 3 (C16:1 ω6c and/or C16:1 ω7c, 17.3%), iso-C15:0 (15.0%), iso-C15:0 G (9.0%), C15:0 ω6c (7.4%), iso-C15:0 (7.4%), and iso-C16:0 (5.3%). The major respiratory quinone and polyamine were MK-6 and sym-homospermidine, respectively. The major polar lipids were phosphatidylethanolamine, an unidentified aminophospholipid, and an unidentified lipid. The DNA G+C content of strain IMCC34762T was 34.4 mol%. Based on the taxonomic data presented in this study, strain IMCC34762T represents a novel species within the genus Flavobacterium, for which the name Flavobacterium aquariorum, sp. nov. is proposed. The type strain is IMCC34762T (= KACC 19725T = NBRC 113425T).

Abstract

A novel Gram-stain-negative, motile by means of gliding, and short rod-shaped bacterium, designated HS916T, was isolated from soil polluted by sewer water in Cheonan-si, South Korea. Growth occurred at 10–35°C (optimum 30°C), pH 6.0–8.0 (optimum pH 7.0), and 0–1% sodium chloride (NaCl, w/v). Based on similarities of 16S rRNA gene sequences, strain HS916T was closely related to members of the genus Flavobacterium, exhibiting the highest sequence similarities with Flavobacterium glycines Gm-149T (96.4%), followed by F. granuli Kw05T (96.3%), F. fluminis 3R17T (96.3%), F. aquicola TMd3a3T (96.2%), and F. nitratireducens N1T (96.2%). Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain HS916T was placed in a monophyletic cluster with F. nitratireducens N1T and F. fluminis 3R17T. The predominant fatty acids (> 5% of the total) of strain HS916T were iso-C15:0, anteiso-C15:0, iso-C15:0 3-OH, C17:1 ω6с, C16:0 3-OH, iso-C17:0 3-OH, and summed feature 3 (C16:1 ω7с and/or C16:1 ω6с). The major polar lipids of the strain comprised phosphatidylethanolamine, unidentified aminolipids, and five unidentified lipids. The predominant respiratory quinone and the major polyamine were menaquinone-6 (MK-6) and symhomospermidine, respectively. The DNA G + C content of strain HS916T was 34.9 mol%. Based on polyphasic analyses, strain HS916T represents a novel species belonging to the genus Flavobacterium, for which the name Flavobacterium parvum sp. nov. is proposed. The type strain is HS916T (= KACC 19448T = JCM 32368T).

Abstract

A novel, aerobic, Gram-stain-negative, non-motile, non-spore forming, rod-shaped bacterium, designated strain Dol 15-39T, was isolated from a seawater sample near Geoje Island in the South Sea, Republic of Korea. The strain was found to be oxidase-negative and catalase-positive. The isolate was observed to grow at temperatures from 4 to 37°C, at salinities of up to 7%, and at pH levels from 6 to 9; moreover, it was not able to degrade starch, DNA, esculin, or tyrosine. Phylogenetic analysis based on 16S rRNA gene sequences showed that Dol 15-39T was most closely related to Flavobacterium jumunjinense HME7102T with a sequence similarity of 97.3%. However, the levels of DNA-DNA relatedness between Dol 15-39T and the most closely related species were much lower than 70%, confirming that they represented distinct genomic species. The genomic DNA G + C content of Dol 15-39T was calculated to be 32.6 mol%. MK-6 was the predominant respiratory quinine, while iso-C15:0 (25.0%), iso- C15:1 G (17.0%), and iso-C17:0 3-OH (10.4%) were the major cellular fatty acids. Phosphatidylethanolamine was identified as a major polar lipid, while various unidentified aminolipids and polar lipids were also detected. Based on polyphasic taxonomic data, Dol 15-39T represents a novel species of the genus Flavobacterium, for which the name F. aquimarinum sp. nov. is proposed. The type strain is accessible under the culture collection numbers (KEMB 9005-617T = JCM 31930T).

Abstract

Flavobacterial diseases, caused by multiple members of the Family Flavobacteriaceae, elicit serious losses in wild and farmed fish around the world. Flavobacteria are known to be transmitted horizontally; however, vertical transmission has been suspected but proven only for one fish-pathogenic flavobacterial species (e.g., Flavobacterium psychrophilum). Herein, we report on the isolation and molecular identification of multiple Flavobacterium and Chryseobacterium taxa from the ovarian fluid and eggs of feral Great Lakes Chinook salmon (Oncorhynchus tshawytscha). Identified egg- and ovarian fluid-associated flavobacteria were either well-known flavobacterial fish pathogens (e.g., F. psychrophilum and F. columnare), most similar to emerging fish-associated flavobacteria (e.g., F. spartansii, F. tructae, F. piscis, C. piscium, C. scophthalmum), or were distinct from all other described Chryseobacterium and Flavobacterium spp., as determined by phylogenetic analyses using neighbor-joining, Bayesian, and Maximum Likelihood methodologies. The gamete-associated flavobacteria fell into three groups (e.g., those that were recovered from the ovarian fluid but not eggs; those that were recovered from the ovarian fluid and eggs; and those that were recovered from eggs but not ovarian fluid), a portion of which were recovered from eggs that were surface disinfected with iodophor at the commonly used dose and duration for egg disinfection. Some gamete-associated flavobacteria were also found in renal, splenic, and neurological tissues. Systemic polymicrobial infections comprised of F. psychrophilum and F. columnare were also detected at nearly an 11% prevalence. This study highlights the potential role that sexual products of female Great Lakes Chinook salmon may play in the transmission of fish-associated flavobacteria.

Abstract

A bacterial strain, designated EC11T was isolated from brown alga Ecklonia cava collected from Jeju Island, Korea. EC11T was identified as a Gram-negative, rod-shaped and yellowpigmented bacterial strain. The strain EC11T grew over a temperature range of 10°C to 30°C (optimally at 25°C), and a pH range of 6.0–10.5 (optimally at pH 7.5). Phylogenetic analysis based on 16S rRNA gene sequences showed that strain EC11T belongs to the genus Flavobacterium. Strain EC11T shared close similarity with Flavobacterium jumunjinense HME7102T (96.4%), Flavobacterium dongtanense LW30T (95.8%), Flavobacterium haoranii LQY-7T (95.3%), and Flavobacterium urocaniciphilum (95.1%). The major fatty acids (> 5%) were iso-C17:0 3-OH (22.4%), iso-C15:0 3-OH (19.0%), C15:0 (12.4%), summed feature 3 (comprising C16:1 ω7c/ C16:1 ω6c; 9.78%), iso-C15:1 G (9.6%), and iso-C16:0 3-OH (9.0%). The DNA G+C content was 28.1 mol% and the strain contained MK-6 as the predominant menaquinone. The major polar lipids were phosphatidylethanolamine, two unknown aminolipids and three unknown polar lipids. Based on phenotypic, chemotaxonomic and phylogenetic analysis, strain EC11T represents a novel species of the Flavobacterium genus, for which the name Flavobacterium jejuensis sp. nov. is proposed. The type strain of F. jejuensis is EC11T (=KCTC 42149T = JCM 30735T).

Abstract: A novel bacterial strain, designated ARSA-111T, was isolated from a freshwater reservoir in Cheonan, Korea. Phylogenetic analysis based on 16S rRNA gene sequences suggested that the isolate belonged to the genus Flavobacterium of phylum Bacteroidetes. The 16S rRNA gene sequence of strain ARSA-111T showed a high degree of sequence similarity to those of Flavobacteium cheonanense KACC 14972T (97.3%), F. aquatile JCM 20475T (97.1%), and other type strains of the genus Flavobacterium (＜97.0%). The phylogenetic tree and network analysis (i.e. median-joining) based on 16S rRNA gene sequences showed that strain ARSA-111T is most closely related to F. aquatile JCM 20475T. DNA-DNA hybridization experiment revealed ＜70% of genomic relatedness among strain ARSA-111T, F. aquatile JCM 20475T and F. cheonanense KACC 14972T. The isolate had iso-C15:1, iso-C15:0, and iso-C15:0 3-OH as predominant cellular fatty acids and MK-6 as a predominant menaquinone. The genomic DNA G+C content of the isolate was 35.6 mol%. On the basis of these data, strain ARSA-111T is considered to be a novel species of the genus Flavobacterium, for which the name Flavobacterium aquaticum sp. nov. is proposed. The type strain is strain ARSA-111T (=KACC 14973T =KCTC 23185T = JCM 17070T).

Abstract: A novel bacterium, designated strain ARSA-15T, was isolated from a freshwater sample collected from the Cheonho reservoir, Cheonan, Republic of Korea. The isolate was deepyellow pigment, Gram-negative, rod-shaped, non-motile, and catalase- and oxidase-positive. Phylogenetic analysis based on 16S rRNA gene sequences showed that the isolate belongs to the genus Flavobacterium, and shared less than 97% sequence similarity with recognized Flavobacterium species. The novel species was able to grow at 10–37°C, pH 6.5–10.0, and in 0–0.5% (w/v) NaCl concentrations. Chemotaxonomically, iso-C15:1, iso-C15:0, and iso-C16:0 were observed to be the predominant cellular fatty acid, and menaquinone-6 (MK-6) was the predominant respiratory quinone. The major polar lipid patterns of strain ARSA-19T was phosphatidylethanolamine, unknown aminolipid (AL1 and AL2), and unidentified polar lipids (L1, L2, and L3). The genomic DNA G+C content of the isolate was 39.2 mol%. On the basis of polyphasic approach, strain ARSA-15T represents a novel species of the genus Flavobacterium, for which the name Flavobacterium cheonhonense sp. nov. is proposed. The type strain is ARSA-15T (=KACC 14967T =KCTC 23180T =JCM 17064T).

Abstract: Taxonomic studies were performed on three strains isolated from Cheonho reservoir in Cheonan, Korea. The isolates were Gram-negative, aerobic, rod-shaped, non-motile, catalase-positive, and oxidase-positive. Colonies on solid media were cream-yellow, smooth, shiny, and circular. Phylogenetic analysis of the 16S rRNA gene sequences revealed that these strains belong to the genus Flavobacterium. The strains shared 98.6-99.4% sequence similarity with each other and showed less than 97% similarity with members of the genus Flavobacterium with validly published names. The DNA-DNA hybridization results confirmed the separate genomic status of strains ARSA-42T, ARSA-103T, and ARSA-108T. The isolates contained menaquinone-6 as the predominant menaquinone and iso-C15:0, iso-C15:0 3-OH, iso-C15:1 G, and iso-C16:0 3-OH as the major fatty acids. The genomic DNA G+C content of the isolates were 31.4-33.2 mol%. According to the phenotypic and genotypic data, these organisms are classified as representative of three novel species in the genus Flavobacterium, and the name Flavobacterium koreense sp. nov. (strain ARSA-42T =KCTC 23182T =JCM 17066T =KACC 14969T), Flavobacterium chungnamense sp. nov. (strain ARSA-103T =KCTC 23183T =JCM 17068T =KACC 14971T), and Flavobacterium cheonanense sp. nov. (strain ARSA-108T =KCTC 23184T =JCM 17069T =KACC 14972T) are proposed.
