Over the last 25 years, a much broader range of taxonomic studies bacteria has gradually replaced former reliance upon morphological, physiological, and biochemical characterization. This polyphasic taxonomy takes into account all available phenotypic genotypic data integrates them in consensus type classification, framed general phylogeny derived from 16S rRNA sequence analysis. In some cases, classification is compromise containing minimum contradictions. It thought that more parameters...
A polyphasic taxonomic study, including 16S rDNA sequence analysis, DNA-DNA hybridizations, DNA base ratio determinations, amplified 165 restriction whole-cell protein analyses and extensive biochemical characterization, was conducted to clarify the relationships of eight isolates from root nodules Mimosa species one isolate sputum a cystic fibrosis patient. All nine were classified as novel Ralstonia species, for which name taiwanensis sp. nov. is proposed. The type strain LMG 19424T (=...
Minimal standards for describing new taxa within the aerobic endospore-forming bacteria are proposed, following Recommendation 30b of Bacteriological Code (1990 Revision). These minimal recommended as guidelines to assist authors in preparation descriptions novel taxa. They encourage broad polyphasic characterization and construction that practically useful routine diagnostic laboratories. The proposals have been endorsed by Subcommittee on Taxonomy Genus Bacillus Related Organisms...
Scope Dietary fibers capable of modifying gut barrier and microbiota homeostasis affect the progression type 1 diabetes (T1D). Here, we aim to compare modulatory effects inulin‐type fructans (ITFs), natural soluble dietary with different degrees fermentability from chicory root, on T1D development in nonobese diabetic mice. Methods results Female mice were weaned long‐ short‐chain ITFs [ITF(l) ITF(s), 5%] supplemented diet up 24 weeks. incidence, pancreatic‐gut immune responses, function,...
The Bacillus cereus Group comprises organisms that are widely distributed in the environment and of health economic interest. We demonstrate an 'ecotypic' structure populations B. using (i) molecular data from Fluorescent Amplified Fragment Length Polymorphism patterns, ribosomal gene sequences, partial panC 'psychrotolerant' DNA sequence signatures (ii) phenotypic descriptive range growth temperature, psychrotolerance thermal niches. Seven major phylogenetic groups (I to VII) were thus...
The Ralstonia solanacearum species complex has long been recognized as a group of phenotypically diverse strains that can be subdivided into four phylotypes. Using polyphasic taxonomic approach on an extensive set strains, this study provides evidence for and nomenclatural revision members complex. Data obtained from phylogenetic analysis 16S-23S rRNA ITS gene sequences, intergenic spacer (ITS) region sequences partial endoglucanase (egl) DNA-DNA hybridizations demonstrate the R. comprises...
There is a need for easy, practical, reliable and robust techniques the identification classification of bacterial isolates to species level as alternatives 16S rRNA gene sequence analysis DNA–DNA hybridization. Here, we demonstrate that multilocus (MLSA) housekeeping genes valuable alternative technique. An MLSA study 10 (atpD, dnaK, gap, glnA, gltA, gyrB, pnp, recA, rpoB thrC) was performed on 34 representatives genus Ensifer. Genetic comparison with 23S sequences demonstrated clear...
An aerobic endospore-forming bacillus (NVH 391-98(T)) was isolated during a severe food poisoning outbreak in France 1998, and four other similar strains have since been isolated, also mostly from cases. Based on 16S rRNA gene sequence similarity, these were shown to belong the Bacillus cereus Group (over 97% similarity with current species) phylogenetic distance validly described species of genus less than 95%. MLST data, novel form robust well-separated cluster B. Group, constituted most...
Advanced age is associated with chronic low-grade inflammation, which usually referred to as inflammaging. Elderly are also known have an altered gut microbiota composition. However, whether inflammaging a cause or consequence of composition not clear. In this study, from young old conventional mice was transferred germ-free (GF) mice. Four weeks after transfer immune cell populations in spleen, Peyer's patches, and mesenteric lymph nodes conventionalized GF were analyzed by flow cytometry....
