Emetic toxin formation of Bacillus cereus is restricted to a single evolutionary lineage of closely related strains.
TLDR
The data provide evidence for a clonal population structure of cereulide-producing emetic B. cereus and indicate that emetic strains represent a highly clonal complex within a potentially panmictic or weakly clonal background populationructure of the species. Expand
Proposed minimal standards for describing new taxa of aerobic, endospore-forming bacteria.
TLDR
These minimal standards are recommended as guidelines to assist authors in the preparation of descriptions for novel taxa to encourage broad polyphasic characterization and the construction of descriptions that are practically useful in routine diagnostic laboratories. Expand
Frigoribacterium faeni gen. nov., sp. nov., a novel psychrophilic genus of the family Microbacteriaceae.
TLDR
The taxonomic position of five actinobacterial strains isolated from dust, an animal shed, the air inside a museum and soil, and soil was investigated using a polyphasic approach revealed that the strains represent a new lineage in the suborder Micrococcineae and the family Microbacteriaceae of the order Actinomycetales. Expand
Williamsia muralis gen. nov., sp. nov., isolated from the indoor environment of a children's day care centre.
TLDR
The taxonomic status of an actinomycete isolated from indoor building materials of a children's day care centre was studied using the polyphasic approach and it was concluded that strain MA 140/96T should be assigned to a new genus and species, for which the name Williamsia muralis gen. nov. Expand
Quantitative Analysis of Cereulide, the Emetic Toxin of Bacillus cereus, Produced under Various Conditions
TLDR
A quantitative and sensitive chemical assay for cereulide, the heat-stable emetic toxin produced by Bacillus cereus, is developed based on high-performance liquid chromatography (HPLC) connected to ion trap mass spectrometry and a bioassay based on boar sperm motility inhibition was used. Expand
Characterization of Nodularia strains, cyanobacteria from brackish waters, by genotypic and phenotypic methods.
TLDR
According to this study, two genotypes of Nodularia exist in the Baltic Sea, the non-toxic type without gas vesicles fits the description of NODularia sphaerocarpa, whereas the toxic type with gas vESicles resembles the species N. spumigena and Nodularityia baltica. Expand
Cellular fatty acids as chemotaxonomic markers of the genera Anabaena, Aphanizomenon, Microcystis, Nostoc and Planktothrix (cyanobacteria).
The cellular fatty acid content of 22 cyanobacterial strains belonging to the genera Anabaena, Aphanizomenon, Calothrix, Cylindrospermum, Nostoc, Microcystis and Planktothrix were analysed. TheExpand
Toxigenic Strains of Bacillus licheniformis Related to Food Poisoning
TLDR
Toxin-producing isolates of Bacillus licheniformis were obtained from foods involved in food poisoning incidents, from raw milk, and from industrially produced baby food, and showed physicochemical properties similar to those of cereulide, despite having very different biological activity. Expand
Sphingomonas aurantiaca sp. nov., Sphingomonas aerolata sp. nov. and Sphingomonas faeni sp. nov., air- and dustborne and Antarctic, orange-pigmented, psychrotolerant bacteria, and emended description
TLDR
Results from DNA-DNA hybridizations and comparison of protein patterns indicated that the seven strains are members of three distinct species, and three novel species of the genus Sphingomonas are proposed. Expand
Paenibacillus borealis sp. nov., a nitrogen-fixing species isolated from spruce forest humus in Finland.
TLDR
Seven spore-forming, nitrogen-fixing bacterial isolates from spruce forest humus in Finland are proposed as a new species, Paenibacillus borealis sp. Expand
