    In: International Journal of Systematic and Evolutionary Microbiology, Microbiology Society, Vol. 54, No. 5 ( 2004-09-01), p. 1849-1855
    Abstract: Two novel bacteria, with an optimum growth temperature of approximately 60 °C, were isolated from Lu-shan hot springs in the central region of Taiwan. These isolates were aerobic, thermophilic, halotolerant, pink-pigmented, heterotrophic and resistant to gamma-radiation. Both pleomorphic, short, rod-shaped cells and coccoid cells were observed. Strains LS-286 (=ATCC BAA-452=BCRC 17198) and LS-293 T (=ATCC BAA-406 T =BCRC 17173 T ) represented a novel species of the genus Rubrobacter , according to a phylogenetic analysis of the 16S rRNA gene, DNA–DNA hybridization, biochemical features and fatty acid composition. The name Rubrobacter taiwanensis sp. nov. is proposed for this novel species, with LS-293 T as the type strain.

    Inhibition of the Epstein–Barr virus lytic cycle by protoapigenone
    Microbiology Society ; 2011

    In: Journal of General Virology, Microbiology Society, Vol. 92, No. 8 ( 2011-08-01), p. 1760-1768
    Abstract: Epstein–Barr virus (EBV) expresses two transcription factors, Rta and Zta, during the immediate–early stage of the lytic cycle to activate the transcription of early and late genes. This study finds that 0.31 mM protoapigenone from Thelypteris torresiana (Gaud.) inhibits the expression of EBV lytic proteins, including Rta, Zta, EA-D and VCA, in P3HR1 cells after lytic induction with 12- O -tetradecanoylphorbol-13-acetate and sodium butyrate. The lack of expression of EBV lytic proteins after protoapigenone treatment is attributed to the inhibition of the transactivation function of Zta because protoapigenone reduces the transactivation activity of Zta and Gal4–Zta, which contains the transactivation domain of Zta fused with Gal4. In contrast, protoapigenone does not affect the ability of Rta to activate a promoter that contains an Rta-response element, showing that the inhibition is unrelated to Rta. Furthermore, in a lactate dehydrogenase assay, protoapigenone is not toxic to P3HR1 cells at the concentrations that inhibit the function of Zta, showing that protoapigenone is valuable for studying the function of Zta and preventing EBV lytic proliferation.

    Abstract: Vibrio alginolyticus is a Gram-negative bacterium and has been recognized as an opportunistic pathogen in humans as well as marine animals. However, the virulence mechanisms for this species of Vibrio have not been elucidated. This study characterized multiple mechanisms that induce cell death in fish cells upon infection with a V. alginolyticus strain, ZJO. The bacterium required its type III secretion system (T3SS) to cause rapid death of infected fish cells. Dying cells exhibited some features of apoptotic cells, such as membrane blebbing, nuclear condensation and DNA fragmentation. Further studies showed that caspase-3 was activated by the T3SS of the ZJO strain, confirming that infection with V. alginolyticus rapidly induces T3SS-dependent apoptosis in fish cells. Infection with the ZJO strain also led to membrane pore formation and release of cellular contents from infected fish cells, as evidenced by lactate dehydrogenase release and the uptake of a membrane-impermeable dye. Importantly, inhibition of apoptosis did not prevent ZJO-infected cells from releasing cellular contents and did not block cell rounding. Taken together, these data demonstrate that infection with V. alginolyticus may promote at least three different T3SS-dependent events, which lead to the death of fish cells. This study provides an important insight into the mechanism used by Vibrio species to cause host-cell death.

    Abstract: A novel obligate anaerobic organism, designated DONG20-135 T , was isolated from human faeces collected in Beijing, PR China. Cells were Gram-stain-negative, rod-shaped, non-motile and non-spore-forming. Growth occurred at 25‒45 °C (optimum, 30‒35 °C), a pH range of 6–9 (optimum, pH 8) and in the presence of 0‒3.5 % (w/v) NaCl (optimum, 0.5‒1.5 %). The major fatty acids were C 16 : 0 , C 18 : 1  ω 9 c and C 10 : 0 , the polar lipid profile consisted of diphosphatidylglycerol, phosphatidylglycerol, four glycolipids, six aminolipids, three aminophospholipids and four unidentified lipids. No respiratory quinones were detected. The cell-wall peptidoglycan of the strain was A1 γ type, containing meso -diaminopimelic acid. The 16S rRNA gene sequences shared a lower identity ( 〈 92.7 % similarity) with the described species. The phylogenetic tree based on 16S rRNA gene sequences and the protein-concatamer tree showed that strain DONG20-135 T formed a distinct lineage within the family Erysipelotrichaceae . The genomic DNA G + C content was 42.2 mol%. Based on the results of phenotypic, chemotaxonomic and genomic analyses, strain DONG20-135 T represents a novel genus of the family Erysipelotrichaceae , for which the name Copranaerobaculum intestinale gen. nov., sp. nov. is proposed (=KCTC 15868 T =CGMCC 1.17357 T ).

    Abstract: An aerobic denitrifying bacterium, designated as strain CPY4 T , was isolated from activated sludge treating urban sewage under alternating aerobic/anaerobic conditions by an enrichment culture technique. Cells of strain CPY4 T were Gram-stain-negative, aerobic, long rod-shaped, motile by means of single polar flagellum and capable of aerobic denitrification with citrate as the carbon source. Growth of strain CPY4 T was observed at 10–45 °C (optimum, 30–35 °C), at pH 6.0–10.5 (optimum, pH 8.0–8.5) and in 0–5 % NaCl (optimum, 0–3 %; w/v). The 16S rRNA gene sequence of strain CPY4 T showed the highest similarity to Zobellella denitrificans ZD1 T (97.9 %), followed by Zobellella endophytica 59N8 T (97.6 %), Zobellella aerophila JC2671 T (97.2 %), Zobellella taiwanensis ZT1 T (97.1 %) and Zobellella maritima 102-Py4 T (96.3 %). Genome comparisons between CPY4 T and other Zobellella species showed highest digital DNA–DNA hybridization with Z. denitrificans ZD1 T (43.8 %) and highest average nucleotide identity (ANIb and ANIm) of genome nucleotide sequences with Z. denitrificans ZD1 T (90.7 and 92 %, respectively). Phylogenetic analysis revealed that strain CPY4 T fell within the clade comprising the type strains of Zobellella species and formed a phyletic line with them, which was distinct from other members of the family Aeromonadaceae . The sole respiratory ubiquinone was quinone 8. The predominant fatty acids ( 〉 10 % of the total fatty acids) of strain CPY4 T were summed feature 8 (C 18 : 1  ω 6 c and/or C 18 : 1  ω 7 c ), summed feature 3 (C 16 : 1  ω 6 c and/or C 16 : 1  ω 7 c ) and C 16 : 0 . The genomic DNA G+C content was 62.7 mol %. In the polar lipid profile, diphosphatidylglycerol, phosphatidylglycerol, phosphatidyl ethanolamine, phospholipids and aminolipids were the major compounds. Based on the genotypic and phenotypic data, strain CPY4 T represents a novel species of the genus Zobellella , for which the name Zobellella iuensis sp. nov. is proposed. The type strain is CPY4 T (=JCM 34456 T =CGMCC 1.18722 T ).

    Abstract: A taxonomic study was carried out on strain CY1 T , which is a novel bacterium isolated from wastewater sludge of a melamine-producing factory in Sanming city, Fujian, China. Strain CY1 T was shown to rapidly and completely degrade melamine to NH 3 and CO 2 under aerobic conditions. The isolate was Gram-stain-negative, short-rod-shaped and motile by one unipolar flagellum. Growth was observed at salinities from 0 to 7 % NaCl (optimum, 0.1 %), at temperatures from 15 to 50 °C (optimum, 40–45 °C) and at pH 7–9.5 (optimum pH 9.5). Quinone-8 was detected as the major respiratory quinone. 16S rRNA gene sequence comparisons showed that strain CY1 T was affiliated to the family Comamonadaceae in the class Betaproteobacteria . It was most closely related to members of the genera Alicycliphilus (95.5 %), Diaphorobacter (94.6–95.1 %), Acidovorax (92.9–95.4 %), Delftia (93.0–93.6 %) and Comamonas (92.6–93.9 %). The average nucleotide identity (ANI) values between strain CY1 T and those representing related genera ranged from 84.0 to 86.1 % using Mummer, and from 74.9 to 81.1 % using blast . The dominant fatty acids were C 16 : 1 ω7 c and/or C 16 : 1 ω6 c , C 16 : 0 , C 10 : 0 3-OH and C 18 : 1 ω7 c and/or C 18 : 1 ω6 c , and the major polar lipids consisted of phosphatidylethanolamine, diphosphatidylglycerol, phosphatidylglycerol, one unidentified phospholipid and one unidentified aminophospholipid. The G+C content of the chromosomal DNA was 69.5 mol%. On the basis of the phenotypic and phylogenetic data, strain CY1 T represents a novel species of a new genus, for which the name Melaminivora alkalimesophila gen. nov., sp. nov. is proposed. The type strain of Melaminivora alkalimesophila is CY1 T ( = CCTCC AB 2012024 T  = DSM 26006 T ).

    Abstract: The ankyrin (ANK) repeat is one of the most common protein–protein interaction motifs, found predominantly in eukaryotes and bacteria, but the functions of the ANK repeat are rarely researched in animal viruses, with the exception of poxviruses. Infectious spleen and kidney necrosis virus (ISKNV) is a typical member of the genus Megalocytivirus in the family Iridoviridae and is a causative agent of epizootics in fish. The genome of ISKNV contains four putative viral ANK (vANK) repeat proteins and their functions remain largely unknown. In the present study, it was found that ORF124L, a vANK repeat protein in ISKNV, encodes a protein of 274 aa with three ANK repeats. Transcription of ORF124L was detected at 12 h post-infection (p.i.) and reached a peak at 40 h p.i. ORF124L was found to localize to both the nucleus and the cytoplasm in mandarin fish fry cells. ISKNV ORF124L interacted with the mandarin fish I κ B kinase β protein (scIKK β ), and attenuated tumour necrosis factor alpha (TNF- α )- or phorbol myristate acetate (PMA)-induced activity of a nuclear factor κ B (NF- κ B)–luciferase reporter but did not interfere with the activity of an activator protein 1 (AP-1)–luciferase reporter. Phosphorylation of I κ B α and nuclear translocation of NF- κ B were also impaired by ISKNV ORF124L. In summary, ORF124L was identified as a vANK repeat protein and its role in inhibition of TNF- α -induced NF- κ B signalling was investigated through interaction with the mandarin fish IKK β . This work may help to improve our understanding of the function of fish iridovirus ANK repeat proteins.
