The 16S rDNA sequences of four strains, i.e. three type strains of Actinobispora and strain 6330T, were determined and compared with those of representatives of the family Pseudonocardiaceae by using two tree-making algorithms. All the validly described species of the genera Actinobispora and Pseudonocardia were consistently recovered as a mixed group in(More)
The type strains of 451 validly described Streptomyces species were screened using the BOX-PCR fingerprint technique. Of the different primers tested, the BOX primer yielded the most robust and reproducible band patterns. The majority of the species (350) had an unique pattern each. A total number of 30 clusters were delineated comprising species with(More)
A Gram-positive, rod-shaped, non-motile bacterium, designated strain wged11T, was isolated from the root of ginseng, and its taxonomic position was established using a polyphasic approach. Phylogenetic analysis based on 16S rRNA gene sequences showed that this organism formed a robust clade with recognized species of the genus Leifsonia. Strain wged11T was(More)
An actinomycete, strain FXJ46(T), was isolated from cypress forest soil in northern China and shown to have chemotaxonomic and morphological properties consistent with streptomycetes. It developed greyish aerial mycelium and pinkish-brown substrate mycelium on oatmeal agar. Phylogenetic analyses based on an almost complete 16S rRNA gene sequence of the(More)
A high-G+C-content, Gram-positive bacterium, strain D10(T), was isolated from the root of Oroxylum indicum, a Chinese medicinal plant. Based on 16S rRNA gene sequence analysis, strain D10(T) was a member of the genus Pseudonocardia and was most closely related, albeit loosely, to Pseudonocardia halophobica. Morphological and chemotaxonomic characteristics(More)
A total of 463 Streptomyces and Kitasatospora type strains were screened using 16S-ITS RFLP fingerprinting (combined restriction digest using enzymes BstUI and HaeIII). In total, 59 clusters could be delineated, each comprising multiple strains with nearly identical patterns. Good correlation was found in general with phylogeny, as revealed by 16S rDNA(More)
A polyphasic study was undertaken to establish the taxonomic status of a Gram-positive, aerobic actinomycete, strain HPA177(T), isolated from a marine sponge, Hymeniacidon perleve. The organism formed branching, non-fragmenting vegetative hyphae and produced black pigment. Chemotaxonomic characteristics were consistent with its assignment to the genus(More)
The taxonomic positions of two gamma- and UV-ray-resistant strains isolated from radiation-polluted soil in north-west China were determined in a polyphasic study. The organisms, designated R12(T) and R13(T), were Gram-stain-positive, non-spore-forming cocci, which contained MK-8 as the major respiratory quinone and C(16 : 1)omega7c and C(16 : 0) as major(More)
BACKGROUND Thiopental is frequently used for the treatment of intracranial hypertension after severe head injury. Its long-term administration increases the incidence of nosocomial infections, which contributes to the high mortality rate of these patients. However, the mechanism of its immunosuppressing effect remains unknown. METHODS The effect of(More)
A DNA-DNA hybridization survey was performed on 13 Streptomyces species and two subspecies, dispersed over five genotypically defined clusters as delineated by Lanoot et al. [Syst Appl Microbiol 27 (2004), 84-92]. Within each of the latter clusters, strains shared DNA-DNA relatedness values above 70 %. On the basis of published recommendations, the(More)
