( 1991 ) Lactobacillus uli sp. nov. and Lactobacillus rimae sp. nov. from the human gingival crevice and emended descriptions of lactobacillus minutus and Streptococcus parvulus. PMID : 1854640 DOI : 10.1099/00207713-41-2-261 Abstract >>
Lactobacillus uli sp. nov. and Lactobacillus rimae sp. nov. are described. These organisms are short, gram-positive, strictly anaerobic, rod-shaped bacteria that have DNA G+C contents of 53 and 45 mol%, respectively, produce major amounts of lactic acid, and have been isolated from human gingival crevices and periodontal pockets. The major cellular fatty acid derivatives for both species are C18:1 cis-9 fatty acid methyl ester and C18:1 cis-9 dimethylacetyl. The type strain of L. uli is strain VPI D76D-27C (= ATCC 49627), and the type strain of L. rimae is strain D140H-11A (= ATCC 49626). Emended descriptions of Lactobacillus minutus (based on selected strains) and Streptococcus parvulus (based on many additional strains) also are given.

( 2004 ) Status of strains that contravene Rules 27(3) and 30 of the Bacteriological Code. Request for an opinion. PMID : 14742499 DOI : 10.1099/ijs.0.03022-0 Abstract >>
In the period from January 2001, at least 207 new names proposed in articles in the International Journal of Systematic and Evolutionary Microbiology or cited in Validation Lists are not in accordance with Rules 27(3) and 30 of the Bacteriological Code. The purpose of the present Request for an Opinion is to clarify the status of the names listed and to provide a solution whereby they may be considered to be validly published.

( 2015 ) Olsenella scatoligenes sp. nov., a 3-methylindole- (skatole) and 4-methylphenol- (p-cresol) producing bacterium isolated from pig faeces. PMID : 25634945 DOI : 10.1099/ijs.0.000083 Abstract >>
Strain SK9K4(T), which is a strictly anaerobic, non-motile, non-sporulating, Gram-stain-positive, saccharolytic coccobacillus, was isolated from pig faeces. SK9K4(T) metabolized indol-3-acetic acid to 3-methylindole (skatole), which is the main contributor to boar taint; it also produced 4-methylphenol (p-cresol) from p-hydroxyphenylacetic acid. Phylogenetic analyses, based on 16S rRNA gene sequences, revealed that the isolate represented a new lineage within the genus Olsenella of the family Atopobiaceae . Strain SK9K4(T) was most closely related to the type strains of the three species of the genus Olsenella with validly published names; Olsenella profusa DSM 13989(T) (93.6%), Olsenella uli DSM 7084(T) (93.5%) and Olsenella umbonata DSM 22620(T) (92.7%). DNA-DNA relatedness values of strain SK9K4(T) with O. profusa , O. uli and O. umbonata were 28.3%, 69.1% and 27.2%, respectively. The genomic DNA G+C content was 62.1 mol% and the major cellular fatty acids (constituting >10% of the total) were C(14 : 0) and C(18 : 1)�s9c. The major end product of glucose fermentation was lactic acid, with minor amounts of acetic acid and formic acid; no H2 was produced. Discrepancies in the fatty acid profiles, the MALDI-TOF mass spectra of cell extracts and the physiological and biochemical characteristics differentiated strain SK9K4(T) from other species of the genus Olsenella and indicate that the isolate represents a novel species within this genus. The name Olsenella scatoligenes sp. nov., is proposed and the type strain is SK9K4(T) (= JCM 19907(T) = DSM 28304(T)).

( 2001 ) Characterization of novel human oral isolates and cloned 16S rDNA sequences that fall in the family Coriobacteriaceae: description of olsenella gen. nov., reclassification of Lactobacillus uli as Olsenella uli comb. nov. and description of Olsenella profusa sp. nov. PMID : 11594611 DOI : 10.1099/00207713-51-5-1797 Abstract >>
The diversity of organisms present in the subgingival pockets of patients with periodontitis and acute necrotizing ulcerative gingivitis (ANUG) were examined previously. The 16S rRNA genes of subgingival plaque bacteria were amplified using PCR with a universal forward primer and a spirochaete-selective reverse primer. The amplified DNA was cloned into Escherichia coli. In one subject with ANUG, 70 clones were sequenced. Seventy-five per cent of the clones were spirochaetal, as expected. Twelve of the remaining clones fell into two clusters that represent novel phylotypes in the family Coriobacteriaceae. The first novel phylotype was most closely related to Atopobium rimae (98% similarity). The phylotype probably represents a novel Atopobium species, but will not be named until cultivable strains are obtained. The second novel phylotype was only 91% similar to described Atopobium species and 84% similar to Coriobacterium glomerans. The 16S rRNA sequences of the type strain of Lactobacillus uli and a strain representing the Moores' Eubacterium group D52 were determined as part of on ongoing sequence analysis of oral bacteria. The sequence for L. uli was more than 99.8% similar to sequences for the second clone phylotype. It therefore appears that the second clone phylotype and L. uli represent the same species. The sequence for the Eubacterium D52 strain was 95.6% similar to that of L. uli. The G+C content of the DNA of L. uli and Eubacterium D52 is 63-64 mol %. These organisms are thus distinct from the neighbouring genus Atopobium, which has a DNA G+C content of 35-46 mol%. A new genus, Olsenella gen. nov., is proposed for these two species on the basis of phenotypic characteristics and 16S rRNA sequence analysis to include Olsenella uli comb. nov. and Olsenella profusa sp. nov.

( 2011 ) Olsenella umbonata sp. nov., a microaerotolerant anaerobic lactic acid bacterium from the sheep rumen and pig jejunum, and emended descriptions of Olsenella, Olsenella uli and Olsenella profusa. PMID : 20435744 DOI : 10.1099/ijs.0.022954-0 Abstract >>
Strain A2 is an anaerobic, variably Gram-stain-positive, non-spore-forming, small and irregularly rod-shaped bacterium from the ruminal fluid of a sheep that has been described informally as a representative of 'Olsenella (basonym Atopobium) oviles'. Three phenotypically similar bacterial strains (lac15, lac16 and lac31(T)) were isolated in concert with Veillonella magna lac18(T) from the mucosal jejunum of a pig. A phylogenetic analysis based on 16S rRNA gene sequences revealed that strains A2, lac15, lac16 and lac31(T) formed a genetically coherent group (100 % interstrain sequence similarity) within the bigeneric Olsenella-Atopobium branch of the family Coriobacteriaceae, class Actinobacteria. This group was most closely related to the type strains of the two recognized Olsenella species, namely Olsenella uli (sequence similarity of 96.85 %) and Olsenella profusa (sequence similarity of 97.20 %). The sequence similarity to the type strain of Atopobium minutum, the type species of the genus Atopobium, was 92.33 %. Unlike those of O. uli and O. profusa, outgrown colonies of strains A2, lac15, lac16 and lac31(T) were opaque and greyish-white with an umbonate elevation on solid culture media. The four novel strains were characterized as being well-adapted and presumably indigenous to the gastrointestinal tract of homoeothermic vertebrates: they were mesophilic, microaerotolerant, neutrophilic and acidotolerant, bile-resistant, mucin-utilizing and markedly peptidolytic lactic acid bacteria. The results of DNA-DNA hybridizations, cellular fatty acid analysis and other differential phenotypic (physiological and biochemical) tests confirmed that strains A2, lac15, lac16 and lac31(T) represent a novel species of the genus Olsenella. On the basis of the genotypic and phenotypic results, we therefore describe Olsenella umbonata sp. nov., with lac31(T) (= CCUG 58604(T) = DSM 22620(T) = JCM 16156(T)) as the type strain and A2 (= CCUG 58212 = DSM 22619 = JCM 16157) as an additionally available reference strain. Also, based on our data, we propose emended descriptions of the genus Olsenella and the species Olsenella uli and Olsenella profusa.

Based on a list of 205 names proposed in original articles in the International Journal of Systematic and Evolutionary Microbiology or cited in Validation Lists from January 2001 that are not in accordance with Rules 27(3) and 30 of the International Code of Nomenclature of Bacteria (the Code), the Judicial Commission rules that names contained in lists 2-4 are to be considered to be validly published and that deposit in more than one collection in different countries is documented. Names included in list 1 are only to be considered validly published if evidence is presented that the strains have been deposited in additional collections, as laid down by Rules 27 (3) and 30 of the Code.
