Previously, nine fecal isolates from wild birds and a domestic swine were identified as helicobacters by phenotypic characterization and reaction with a helicobacter genus-specific DNA probe. These isolates fell into three biotypes by analysis of phenotypic traits. To further characterize these isolates, full 16S rRNA sequences were determined for strains representing each biotype, and sequence comparison indicated that the strains represented three novel, phylogenetically defined Helicobacter species. Three 16S rRNA-based DNA probes were designed and used to identify the remaining strains. Probe reactivity divided the strains into the same three groups identified phenotypically. Six of the isolates represented a new species of the genus Helicobacter for which we propose the name Helicobacter pametensis sp. nov. The following phenotypic features distinguished H. pametensis from other Helicobacter and Campylobacter species: positive tests for oxidase, catalase, alkaline phosphatase, nitrate reduction, growth at 42 degrees C, and growth in the presence of 1% glycine; negative tests for urease, gamma glutamyl transpeptidase, indoxyl acetate hydrolysis, and hippurate hydrolysis; and susceptibility to nalidixic acid and cephalothin. H. pametensis cells were motile and possessed one subterminal sheathed flagellum at each end. The two additional Helicobacter species were similar to H. pametensis except that they were urease positive, hydrolyzed indoxyl acetate, and were resistant to cephalothin. Because these two additional species are phenotypically similar and are represented by only two isolates for one species and one isolate for the other, they are not formally named but are referred to as Helicobacter sp. "Bird-B" and Helicobacter sp. "Bird-C."(ABSTRACT TRUNCATED AT 250 WORDS)

Three subspecies of Staphylococcus sciuri, S. sciuri subsp. sciuri Kloos, Schleifer, and Smith 1976, 23AL emend. Kloos et al. 1997 [corrected], S. sciuri subsp. carnaticus subsp. nov., and S. sciuri subsp. rodentium subsp. nov., are described on the basis of their ribotype patterns, DNA-DNA liquid hybridization data, and phenotypic characteristics. Normalized ribotyping subdivided the S. sciuri patterns into three blocks of patterns, each corresponding to a subspecies. Each subspecies formed a separate, well-defined DNA similarity group when DNA-DNA hybridizations were conducted under stringent (70 degrees C) reassociation conditions. S. sciuri subsp. sciuri could be distinguished from the other subspecies on the basis of its ability to produce acid from D-cellobiose, alkaline phosphatase activity, and inability to produce either clumping factor or protein A. S. sciuri subsp. carnaticus could be distinguished by its ability to produce acid aerobically from D-xylose and maltose, inability to produce acid from D-melezitose, and smaller colony size on P agar. S. sciuri subsp. rodentium could be distinguished by its positive reaction in the latex agglutination test for clumping factor and/or protein A and generally higher frequencies and levels of oxacillin and methicillin resistance. All 40 strains of S. sciuri tested (including representatives of all three subspecies) hybridized with the mecA gene probe. All strains of S. sciuri subsp. sciuri, 79% of the strains of S. sciuri subsp. carnaticus and 89% of the strains of S. sciuri subsp. rodentium exhibited extracellular, staphylolytic enzyme activity. This activity was associated with an enzyme(s) that immunoblotted with a lysostaphin-specific monoclonal antibody; however, only three strains hybridized with a lysostaphin (end) gene probe. The type strain of S. sciuri subsp. carnaticus is DD 791 (= ATCC 700058), and the type strain of S. sciuri subsp. rodentium is DD 4761 (= ATCC 700061).

A hyperthermophilic, anaerobic archaeon was isolated from hydrothermal fluid samples obtained at the Okinawa Trough vents in the NE Pacific Ocean, at a depth of 1395m. The strain is obligately heterotrophic, and utilizes complex proteinaceous media (peptone, tryptone, or yeast extract), or a 21-amino-acid mixture supplemented with vitamins, as growth substrates. Sulfur greatly enhances growth. The cells are irregular cocci with a tuft of flagella, growing optimally at 98 degrees C (maximum growth temperature 102 degrees C), but capable of prolonged survival at 105 degrees C. Optimum growth was at pH 7 (range 5-8) and NaCl concentration 2.4% (range 1%-5%). Tryptophan was required for growth, in contrast to the closely related strains Pyrococcus furiosus and P. abyssi. Thin sections of the cell, viewed by transmission electron microscopy, revealed a periplasmic space similar in appearance to the envelope of P. furiosus. The predominant cell membrane component was tetraether lipid, with minor amounts of diether lipids. Treatment of the cells by mild osmotic shock released an extract that contained a Zn(2+)-dependent alkaline phosphatase. Phylogenetic analysis of the sequences encoding 16S rRNA and glutamate dehydrogenase places the isolate with certainty within the genus Pyrococcus although there is relatively low DNA-DNA hybridization (< 63%) with described species of this genus. Based on the reported results, we propose a new species, to be named Pyrococcus horikoshii sp.nov.

Strain 130ZT was isolated from the bovine rumen. It is a facultatively anaerobic, pleomorphic, Gram-negative rod. It exhibits a 'Morse code' form of morphology, which is characteristic of the genus Actinobacillus. Strain 130ZT is a capnophilic, osmotolerant succinogen that utilizes a broad range of sugars. It accumulates high concentrations of succinic acid (> 70 g l-1). Strain 130ZT is positive for catalase, oxidase, alkaline phosphatase and beta-galactosidase, but does not produce indole or urease. Acid but no gas is produced from D-glucose and D-fructose. 16S rRNA sequence analysis places strain 130ZT within the family Pasteurellaceae; the most closely related members of the family Pasteurellaceae have 16S rRNA similarities of 95.5% or less with strain 130ZT. Strain 130ZT was compared with Actinobacillus lignieresii and the related Bisgaard Taxa 6 and 10. Based upon morphological and biochemical properties, strain 130ZT is most similar to members of the genus Actinobacillus within the family Pasteurellaceae. It is proposed that strain 130ZT be classified as a new species, Actinobacillus succinogenes. The type strain of Actinobacillus succinogenes sp. nov. is ATCC 55618T.

From 1997 to 1999 seven isolates of Campylobacter-like organisms from five patients that were exhibiting symptoms of gastroenteritis, including fever, stomach malaise, and diarrhea, were investigated. The organisms were isolated from stool samples and found to exhibit a diverse colony morphology; hence multiple isolates were submitted from one of the patients. All isolates were found to be identical. The organisms were catalase, urease, alkaline phosphatase, and nitrate negative but oxidase and indoxyl acetate positive. They grew at 37 degrees C but not at 42 degrees C, and three of the isolates from two different patients were sensitive to nalidixic acid and cephalothin. Full 16S rRNA sequence analysis not only grouped these organisms within the Helicobacter genus but also differentiated them from previously identified Helicobacter species. The closest relative by phylogenetic analysis was Helicobacter sp. flexispira taxon 1. Electron microscopy showed that these isolates had one or two bipolar flagella; however, the periplasmic fibers, a characteristic of the known Helicobacter sp. flexispira taxa, were not observed. The present isolates also lacked a flagellar sheath, a trait shared with four other Helicobacter spp., H. canadensis, H. mesocricetorum, H. pullorum, and H. rodentium. On the basis of the unique phenotypic properties of these isolates and 16S rRNA sequence analysis, we propose the classification of a new Helicobacter species, Helicobacter winghamensis sp. nov.

Three coryneform strains from clinical specimens were studied. They belonged to the genus Corynebacterium, since they had type IV cell walls containing corynemycolic acids. They had phenotypic characteristics that included alpha-glucosidase, pyrazinamidase and alkaline phosphatase activities and fermentation of glucose, ribose, maltose and sucrose. These are the characteristics of Corynebacterium xerosis. Since this species is very rare in human pathology, the strains were studied in more detail by comparing the 16S-23S intergenic spacers, rDNA sequences and levels of DNA similarity of these three strains and those of the reference strains C. xerosis ATCC 373T and Corynebacterium amycolatum CIP 103452T. According to DNA-DNA hybridization data, the three novel strains are members of the same species (level of DNA similarity >72%). Phylogenetic analysis revealed that these strains are closely related to C. xerosis and C. amycolatum, but DNA-relatedness experiments showed clearly that they constitute a distinct new species, with levels of DNA relatedness of less than 23% to C. xerosis ATCC 373T and less than 5% to C. amycolatum CIP 103452T. Two other alpha-glucosidase-positive strains presenting the same biochemical characteristics were included in the study and proved to be C. amycolatum. This new species can be differentiated from C. xerosis and C. amycolatum strains by carbon source utilization, intergenic spacer region length profiles and some biochemical characteristics such as glucose fermentation at 42 degrees C and growth at 20 degrees C. The name Corynebacterium freneyi sp. nov. is proposed with the type strain ISPB 6695110T (= CIP 106767T = DSM 44506T).

The taxonomic position of three novel sea-water isolates was determined. The strains studied were strictly aerobic, heterotrophic, pigmented, motile by gliding, Gram-negative and oxidase-, catalase-, beta-galactosidase- and alkaline phosphatase-positive. 16S rRNA gene sequence phylogenetic analysis indicated that the strains KMM 6020T, KMM 6021 and KMM 6028 occupied a distinct lineage within the family Flavobacteriaceae. The major respiratory quinone was MK-6. The predominant fatty acids were i15 : 0, i15 : 1, i15 : 0 3-OH, i17 : 1omega9c and i17 : 0 3-OH. On the basis of phenotypic, chemotaxonomic, genotypic and phylogenetic characteristics, the novel bacteria were assigned to the genus Aquimarina gen. nov., as Aquimarina muelleri gen. nov., sp. nov. The type strain is KMM 6020T (=KCTC 12285T=LMG 22569T). From the results of the 16S rRNA gene sequence analysis and phenotypic features, the species [Cytophaga] latercula Lewin 1969 is proposed to be reclassified in the new genus Stanierella as Stanierella latercula gen. nov., comb. nov., with type strain CIP 104806T (=ATCC 23177T=NCIMB 1399T=LMG 1343T).

The taxonomic position of a novel marine bacterium isolated from the green alga Ulva fenestrata collected in the Sea of Japan was established. Cells of the strain studied, designated KMM 6017T, were strictly aerobic, heterotrophic, pink-pigmented, non-motile by gliding, Gram-negative and oxidase-, catalase-, beta-galactosidase- and alkaline phosphatase-positive. 16S rRNA gene sequence analysis indicated that the strain occupied a distinct lineage within the phylum 'Bacteroidetes' and formed a cluster with [Flexibacter] tractuosus and Reichenbachia agariperforans. The G+C content of the DNA of KMM 6017T was 40.2 mol%. The major respiratory quinone was MK-7. The predominant fatty acids were i15 : 1, i15 : 0 and i17 : 0 3-OH (34.2, 24 and 7.7 %, respectively). On the basis of phenotypic, chemotaxonomic, genotypic and phylogenetic characteristics, the novel bacterium was assigned to the genus Roseivirga gen. nov., as Roseivirga ehrenbergii gen. nov., sp. nov. The type strain is KMM 6017T (=KCTC 12282T=LMG 22567T).

A bacterial strain, designated KMM 6049T, was isolated from the sea urchin Strongylocentrotus intermedius inhabiting the Sea of Japan. The bacterium studied was strictly aerobic, heterotrophic, yellow-pigmented, non-motile, Gram-negative and oxidase-, catalase-, beta-galactosidase- and alkaline phosphatase-positive. 16S rRNA gene sequence analysis indicated that strain KMM 3524T was closely related to Salegentibacter holothuriorum and Salegentibacter salegens (sharing 97.7 and 98 % sequence similarity, respectively). DNA-DNA relatedness levels between strains KMM 6049T and S. holothuriorum KMM 3524T and S. salegens DSM 5424T were 24 and 45 %, respectively, indicating that KMM 6049T belongs to a novel species of the genus Salegentibacter, for which the name Salegentibacter mishustinae sp. nov. is proposed. The type strain is KMM 6049T (=KCTC 12263T=LMG 22584T=NBRC 100592T).

A novel marine bacterium isolated from the soft coral Paragorgia arborea in the Sea of Okhotsk was studied by using a polyphasic taxonomic approach. The strain, KMM 6029T, was strictly aerobic, heterotrophic, yellow-pigmented, non-motile by gliding, Gram-negative and oxidase-, catalase- and alkaline phosphatase-positive. From results of 16S rRNA gene sequence analysis, strain KMM 6029T occupied a distinct lineage within the family Flavobacteriaceae and showed 95.5 % similarity to its closest relative, Formosa algae. The DNA G+C content was 37.6 mol%. Major respiratory quinone was MK-6. The predominant fatty acids were i15 : 0, a15 : 0, i15 : 1, a15 : 1, i16 : 1, i16 : 0, i16 : 0 3-OH and summed feature 3 (i15 : 0 2-OH and/or 16 : 1omega7c). On the basis of phenotypic, chemotaxonomic, genotypic and phylogenetic characteristics the novel bacterium has been assigned to Bizionia gen. nov., as Bizionia paragorgiae gen. nov., sp. nov. The type strain is KMM 6029T (=KCTC 12304T=LMG 22571T).
