Phenotypic and phylogenetic studies were performed on three strains of Gram-negative, rod-shaped organisms recovered from dead birds of the tit families (blue tit, coal tit and long-tailed tit). Morphological, cultural and biochemical studies indicated that the organisms were related to the family Cardiobacteriaceae in the gamma-subclass of the Proteobacteria. Comparative 16S rRNA gene sequencing studies confirmed these findings and demonstrated that the bacterium represents a hitherto unknown subline within this family. The closest phylogenetic relative of the strains isolated from the birds was found to be Suttonella indologenes, although a sequence divergence of approximately 5 % demonstrated that the unknown bacterium represented a novel species. On the basis of the results of the phylogenetic analysis and phenotypic criteria, it is proposed that the bacteria recovered from the diseased birds represent a novel species, Suttonella ornithocola sp. nov., with strain B6/99/2T (=CCUG 49457T=NCTC 13337T) as the type strain.

Phenotypic and phylogenetic studies were performed on six unidentified, Gram-positive, catalase-negative, chain-forming Streptococcus-like organisms recovered from grey seals. Biochemically the six strains were highly related to each other, but they did not appear to correspond to any recognized species of the genus Streptococcus. Comparative 16S rRNA gene sequencing studies confirmed that phylogenetically the strains were members of the genus Streptococcus, but sequence divergence values of greater than 3 % compared with reference streptococcal species demonstrated that the organisms from seals represent a novel species. SDS-PAGE analysis of whole-cell proteins confirmed the phenotypic distinctiveness of the seal organisms. Based on biochemical criteria and molecular chemical and genetic evidence, it is proposed that the unknown organism from seals be classified as a novel species, Streptococcus halichoeri sp. nov., the type strain of which is CCUG 48324T (=CIP 108195T).

Biochemical Testing

A previously undescribed filamentous, beaded, Gram-positive, rod-shaped bacterium was isolated from pus of a human dental abscess. Based on its cellular morphology and the results of biochemical testing the organism was tentatively identified as a member of the genus Actinomyces, but it did not correspond to any currently recognized species of this genus. Comparative 16S rRNA gene sequencing studies showed the bacterium represents a distinct subline within the genus Actinomyces, clustering within a group of species that includes Actinomyces bovis, the type species of the genus. Sequence divergence values of >8 % with other recognized species within this phylogenetic group clearly demonstrated that the organism represents a hitherto unknown species. Based on biochemical and molecular phylogenetic evidence, it is proposed that the unidentified organism recovered from a dental abscess be classified as a novel species, Actinomyces dentalis sp. nov. The type strain is R18165T (=CCUG 48064T=CIP 108337T).

Four Gram-stain-positive, catalase-negative, coccoid-shaped isolates were obtained from the oral cavities of wild boars and characterized by phenotypic and phylogenetic studies. On the results of biochemical tests, the organisms were tentatively identified as a streptococcal species. Comparative 16S rRNA gene sequencing studies confirmed that the organisms are members of the genus Streptococcus, with Streptococcus equi subsp. equi ATCC 33398T as their closest phylogenetic relative (94.7 % similarity). DNA–DNA hybridization analysis showed that the isolates displayed less than 10 % relatedness to Streptococcus equi subsp. equi DSM 20561T. From the phylogenetic and phenotypic evidence, the four isolates represent a novel species of the genus Streptococcus, for which the name Streptococcus dentapri sp. nov. (type strain NUM 1529T =JCM 15752T =DSM 21999T) is proposed.

Two Gram-negative, anaerobic, non-spore-forming, rod-shaped organisms were isolated from a swine-manure storage pit. Based on morphological and biochemical criteria, the strains were tentatively identified as belonging to the genus Bacteroides but they did not appear to correspond to any recognized species of the genus. Comparative 16S rRNA gene sequencing studies showed that the strains were related closely to each other and confirmed their placement in the genus Bacteroides, but sequence divergence values of >10 % from reference Bacteroides species demonstrated that the organisms from manure represent a novel species. Based on biochemical criteria and molecular genetic evidence, it is proposed that the unknown isolates from manure be assigned to a novel species of the genus Bacteroides, as Bacteroides coprosuis sp. nov. The type strain is PC139T (=CCUG 50528T=NRRL B-41113T).

Two strains of an unidentified, Gram-positive, catalase-negative, chain-forming, coccus-shaped organism recovered from seals were characterized using phenotypic and molecular taxonomic methods. Based on morphological and biochemical criteria the strains were tentatively identified as streptococci but they did not appear to correspond to any recognized species of the genus Streptococcus. Comparative 16S rRNA gene sequencing studies showed that the strains were closely related to each other and confirmed their placement in the genus Streptococcus. Sequence divergence values of >5 % with reference streptococcal species demonstrated the organisms from seals represent a novel species. SDS-PAGE analysis of whole-cell proteins confirmed that the two organisms were closely related to each other but were different from all currently defined streptococcal species. Based on biochemical criteria, molecular chemical and molecular genetic evidence, it is proposed that the unknown isolates from seals be assigned to a novel species of the genus Streptococcus, Streptococcus marimammalium sp. nov. The type strain is M54/01/1T (=CCUG 48494T=CIP 108309T).

Morphological, biochemical and molecular genetic studies were carried out on an unknown non-spore-forming, Gram-negative, rod-shaped bacterium which was isolated from dog faeces. The bacterium grew under anaerobic conditions, was asaccharolytic, resistant to 20 % (v/v) bile and was oxidase- and urease-negative. Phylogenetic analysis based on comparative 16S rRNA gene sequencing showed that the unidentified bacterium clustered with Sutterella wadsworthensis, although a sequence divergence of >5 % indicated that the bacterium from dog faeces represented a previously unrecognized subline within the genus. On the basis of the presented findings, a novel species, Sutterella stercoricanis sp. nov., is described. The type strain of Sutterella stercoricanis is 5BAC4T (=CCUG 47620T=CIP 108024T).

A facultatively anaerobic, endospore-forming bacterium, designated strain P11-6T, was isolated from soil of a ginseng field located in Geumsan County, Republic of Korea. Cells of strain P11-6T were Gram-stain-negative, catalase-negative, motile rods and produced semi-translucent, circular, white colonies on tryptic soy agar. The isolate contained MK-7 as the only menaquinone and anteiso-C15 : 0 as the major fatty acid. Diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, an unknown aminophosphoglycolipid, an unknown aminophospholipid, two unknown phospholipids, three unknown glycolipids and three unknown lipids were detected in the polar lipid profile. The DNA G+C content of strain P11-6T was 41.9 mol%. Phylogenetic analysis based on 16S rRNA gene sequencing showed that strain P11-6T was most closely related to Fontibacillus aquaticus GPTSA 19T (97.2 % sequence similarity) and that it formed a separate lineage with F. aquaticus in the family Paenibacillaceae. Combined phenotypic and DNA–DNA hybridization data supported the conclusion that strain P11-6T represents a novel species in the genus Fontibacillus, for which the name Fontibacillus panacisegetis sp. nov. is proposed; the type strain is P11-6T (=KCTC 13564T =CECT 7605T).

A previously unknown Gram-positive, non-spore-forming, non-lipophilic, catalase-positive, irregular rod-shaped bacterium (M/106/00/5T) was isolated, in mixed culture, from the penis of a Caspian seal (Phoca caspica). The strain was a facultative anaerobe that was able to grow at 22 and 42 °C. Comparative 16S rRNA gene sequencing showed that the organism formed a hitherto unknown subline within the genus Corynebacterium. Sequence divergence values of more than 5 % from other described Corynebacterium species, together with phenotypic differences, showed that the unidentified bacterium represents a previously unrecognized member of this genus. On the basis of phenotypic and phylogenetic considerations, it is proposed that the unknown bacterium isolated from a Caspian seal (strain M/106/00/5T=CCUG 44566T=CIP 107965T) be classified as the type strain of a novel species of the genus Corynebacterium, Corynebacterium caspium sp. nov.
