Arcobacter ellisii sp. nov., isolated from mussels

As part of a study carried out for detecting Arcobacter spp. in shellfish, three mussel isolates that were Gram-negative slightly curved rods, non-spore forming, showed a new 16S rDNA-RFLP pattern with a specific identification method for the species of this genus. Sequences of the 16S rRNA gene and those of the housekeeping genes rpoB, gyrB and hsp60 provided evidence that these mussel strains belonged to an unknown genetic lineage within the genus Arcobacter. The similarity between the 16S rRNA gene sequence of the representative strain (F79-6^T) and type strains of the other Arcobacter species ranged between 94.1% with A. halophilus and 99.1% with the recently proposed species A. defluvii (CECT 7697^T). DDH results between strain F79-6^T and the type strain of the latter species were below 70% (53 ± 3.0%). Phenotypic characteristics together with MALDITOF mass spectra differentiated the new mussel strains from all other Arcobacter species. All the results indicate that these strains represent a new species, for which the name Arcobacter ellisii sp. nov. with the type strain F79-6^T (=CECT 7837^T = LMG 26155^T) is proposed.     

Arcobacter molluscorum sp. nov., a new species isolated from shellfish

Nineteen bacteria isolates recovered from shellfish samples (mussels and oysters) showed a new and specific 16S rDNA-RFLP pattern with an Arcobacter identification method designed to recognize all species described up to 2008. These results suggested that they could belong to a new species. ERIC-PCR revealed that the 19 isolates belonged to 3 different strains. The sequence of the 16S rRNA gene of a representative strain (F98-3^T) showed 97.6% similarity with the closest species Arcobacter marinus followed by Arcobacter halophilus (95.6%) and Arcobacter mytili (94.7%). The phylogenetic analysis with the16S rRNA, rpoB, gyrB and hsp60 genes placed the shellfish strains within the same cluster as the three species mentioned (also isolated from saline habitats) but they formed an independent phylogenetic line. The DDH results between strain F98-3^T and A. marinus (54.8% ± 1.05), confirmed that it represents a new species. Several biochemical tests differentiated the shellfish isolates from all other Arcobacter species. Although the new species was different from A. mytili, they shared not only the same habitat (mussels) but also the characteristic of being so far the only Arcobacter species that are simultaneously negative for urea and indoxyl acetate hydrolysis. All results supported the classification of the shellfish strains as a new species, for which the name Arcobacter molluscorum sp. nov. with the type strain F98-3^T is proposed (=CECT 7696^T = LMG 25693^T).     

Bradyrhizobium rifense sp. nov. isolated from effective nodules of Cytisus villosus grown in the Moroccan Rif

Two bradyrhizobial strains, CTAW71(T) and CTAW69, previously isolated from root nodules of Cytisus villosus, have been analysed using a polyphasic approach. These strains have identical 16S rRNA genes and their closest relative species is Bradyrhizobium cytisi, whose type strain CTAW11(T) presented 99.8% identity with respect to strain CTAW71(T). Despite the closeness of the 16S rRNA genes, the housekeeping genes recA, atpD and glnII harboured by strain CTAW71(T) were divergent to those from B. cytisi CTAW11(T), with identity values of 93%, 95% and 97%, respectively. These differences were congruent with DNA-DNA hybridization analysis that revealed an average of 37% relatedness between strain CTAW71(T) and B. cytisi CTAW11(T). Phenotypic characteristics were identical for strains CTAW71(T) and CTAW69, but differed from those of the described species from genus Bradyrhizobium. Based on the genotypic and phenotypic data obtained in this study, we propose that strains CTAW71(T) and CTAW69 should be classified into a new species for which the name Bradyrhizobium rifense sp. nov. is proposed (type strain CTAW71(T)=LMG 26781(T)=CECT 8066(T)).     

Chryseobacterium oncorhynchi sp. nov., isolated from rainbow trout (Oncorhynchus mykiss)

Genotypic and phenotypic analyses were performed on five Gram-negative, catalase and oxidase-positive, rod-shaped bacteria isolated from the gill and liver of four rainbow trout. Studies based on comparative 16S rRNA gene sequence analysis showed that the five new isolates shared 99.8-100% sequence similarity and that they belong to the genus Chryseobacterium. The nearest phylogenetic neighbours of the strain 701B-08(T) were Chryseobacterium ureilyticum F-Fue-04IIIaaaa(T) (99.1% 16S rRNA gene sequence similarity) and Chryseobacterium joosteii LMG 18212(T) (98.6%). DNA-DNA hybridization values between the five isolates were 91-99% and ranged from 2 to 53% between strain 701B-08(T) and the type strains of phylogenetically closely related species of Chryseobacterium. Strain 701B-08(T) had a DNA G+C content of 36.3 mol%, the major fatty acids were iso-C(15:0), iso-C(17:1)ω9c, C(16:1)ω6c and iso-C(17:0) 3-OH and the predominant respiratory quinone was MK-6. The novel isolates were distinguished from related Chryseobacterium species by physiological and biochemical tests. The genotypic and phenotypic properties of the isolates from rainbow trout suggest their classification as representatives of a novel species of the genus Chryseobacterium, for which the name Chryseobacterium oncorhynchi sp. nov. is proposed. The type strain is 701B-08(T) (=CECT 7794(T)=CCUG 60105(T)).     

Rhizobium nepotum sp. nov. isolated from tumors on different plant species

Five Gram-negative, rod-shaped, non-spore-forming bacteria were isolated from galls on different plant species in Hungary: strain 39/7(T) from Prunus cerasifera Myrobalan, strain 0 from grapevine var. Ezerjó, strain 7/1 from raspberry var. Findus and in Poland, strain C3.4.1 from Colt rootstock (Prunus avium × Prunus pseudocerasus) and strain CP17.2.2 from Prunus avium. Only one of these isolates, strain 0, is able to cause crown gall on different plant species. On the basis of 16S rRNA gene sequence similarity, the strains cluster together and belong to the genus Rhizobium and their closest relative is Rhizobium radiobacter (99.1%). Phylogenetic analysis of the novel strains using housekeeping genes atpD, glnA, gyrB, recA and rpoB revealed their distinct position separate from other known Rhizobium species and confirmed their relation to Rhizobium radiobacter. The major cellular fatty acids are 18:1 w7c, 16:0, 16:0 3OH, summed feature 2 (comprising 12:0 aldehyde, 16:1 iso I and/or 14:0 3OH) and summed feature 3 (comprising 16:1 w7c and/or 15 iso 2OH). DNA-DNA hybridization of strain 39/7(T) with the type strain of R. radiobacter LMG 140(T) revealed 45% DNA-DNA hybridization. Phenotypic and physiological properties differentiate the novel isolates from other closely related species. On the basis of the results obtained, the five isolates are considered to represent a novel species of the genus Rhizobium, for which the name Rhizobium nepotum sp. nov. (type strain 39/7(T)=LMG 26435(T)=CFBP 7436(T)) is proposed.     

Nevskia aquatilis sp. nov. and Nevskia persephonica sp. nov., isolated from a mineral water aquifer and the emended description of the genus Nevskia

Four isolates, with an optimum temperature of about 30°C and an optimum pH for growth of 6.0-6.5, were recovered from a borehole head of a mineral water aquifer in Portugal and from the stored bottles produced on site. Strains F2-63(T) and F2-178 were yellow-pigmented and formed non-motile rod-shaped cells. Strains G6M-30(T) and G6-54 were whitish-pigmented, translucent and form rod-shaped cells with a polar flagellum. The four strains were strictly aerobic, oxidase and catalase positive. The major fatty acids of strains F2-63(T) and F2-178 were C(18:1)ω7c and C(16:0), and the major fatty acids of strains G6M-30(T) and G6-54 were C(18:1)ω7c and C(16:1)ω7c. Ubiquinone 8 was the major respiratory quinone. Based on 16S rRNA gene sequence analysis, physiological and biochemical characteristics two new species of the genus Nevskia are described; Nevskia aquatilis represented by strains F2-63(T) (=LMG 26345 =CECT 7897) and F2-178 (=LMG 26344 =CECT 7898) and Nevskia persephonica represented by strains G6M-30(T) (=DSM 24987 =CECT 7975) and G6-54 (=DSM 25048 =CECT 7976).     

Arcobacter cloacae sp. nov. and Arcobacter suis sp. nov., two new species isolated from food and sewage

Three strains recovered from mussels (F26), sewage (SW28-13^T) and pork meat (F41^T) were characterized as Arcobacter. They did not appear to resemble any known species on the basis of their 16S rDNA-RFLP patterns and the rpoB gene analyses. However, strains F26 and SW28-13^T appeared to be the same species. The 16S rRNA gene sequence similarity of strains SW28-13^T and F41^T to the type strains of all other Arcobacter species ranged from 94.1% to 99.6% and 93.4% to 98.8%, respectively. Phenotypic characteristics and the DNA–DNA hybridization (DDH) results showed that they belonged to 2 new Arcobacter species. A multilocus phylogenetic analysis (MLPA) with the concatenated sequences of 5 housekeeping genes (gyrA, atpA, rpoB, gyrB and hsp60) was used for the first time in the genus, showing concordance with the 16S rRNA gene phylogenetic analysis and DDH results. The MALDI-TOF mass spectra also discriminated these strains as two new species. The names proposed for them are Arcobacter cloacae with the type strain SW28-13^T (=CECT 7834^T = LMG 26153^T) and Arcobacter suis with the type strain F41^T (=CECT 7833^T = LMG 26152^T).     

Hymenobacter perfusus sp. nov., Hymenobacter flocculans sp. nov. and Hymenobacter metalli sp. nov. three new species isolated from an uranium mine waste water treatment system

Three red-pink pigmented strains, designated A1-12(T), A2-50A(T) and A2-91(T), were recovered from two different sites in a uranium mine. For all strains, the optimum growth temperature was 25°C, the optimum pH was 6.0-6.5 and the DNA G+C contents were between 60 and 63.4 mol%. The major respiratory quinone was menaquinone 7 (MK-7) and the fatty acid profiles contained iso- and anteiso-branched C15 fatty acids, summed feature 3 (16:1 ω6c and/or ω7c and/or 15:0 iso 2-OH), summed feature 4 (17:1 anteiso B and/or iso I) and the unsaturated fatty acid 16:1 ω5c as the major components. Phylogenetic analysis of the 16S rRNA gene sequences showed that these organisms represented three distinct branches within the family Flexibacteraceae most closely related to the members of the genus Hymenobacter. Strain A1-12(T) formed a distinct phylogenetic line along with H. rigui KCTC 12533(T) and they shared approximately 98.9% 16S rRNA gene sequence similarity. However, these two strains shared only 14.7% pairwise similarity in their genomic DNA. Strains A2-50A(T) and A2-91(T) formed two distinct lineages, related to the species H. soli KCTC 12607(T), sharing about 95.5% 16S rRNA gene sequence similarity between themselves, and 88.3 and 92.0% with other members of the genus Hymenobacter. Based on the phylogenetic analysis and physiological and biochemical characteristics, these isolates were considered to represent three novel species for which we propose the names Hymenobacter perfusus for strain A1-12(T) (=CIP 110166=LMG 26000), Hymenobacter flocculans for strain A2-50A(T) (=CIP 110139=LMG 25699) and Hymenobacter metalli for strain A2-91(T) (=CIP 110140=LMG 25700).     

Sphingobacterium canadense sp. nov., an isolate from corn roots

A free-living Gram-negative bacterial strain CR11(T) was isolated from corn roots. Polyphasic taxonomy was performed, including API20 NE and API50 CH bacterial identification kits, Biolog analysis, lipids and fatty acid analysis, DNA-DNA hybridization, 16S rRNA and cpn60 gene sequence analyses. 16S rRNA gene sequence analysis indicated that strain CR11(T) belonged to the genus Sphingobacterium and was closely related to Sphingobacterium multivorum IFO 14947(T) (98% similarity) and Sphingobacterium. thalpophilum ATCC 43320(T) (97% similarity). DNA-DNA hybridization showed 11% and 13% DNA re-association with S. multivorum LMG 8342(T) and S. thalpophilum LMG 11520(T), respectively. Major fatty acids (16:0, 15:0 iso and 17:0 iso 3-OH) and the G+C content of the DNA (40.5 mol%), were also similar to those of the genus Sphingobacterium. The predominant respiratory quinone was MK-7. In all analyses, including phenotypic characterization, this isolate was found to be different from the closely related species, S. multivorum and S. thalpophilum. On the basis of these results, this strain represents a new species within the genus Sphingobacterium. The name Sphingobacterium canadense sp. nov. is suggested and the type strain is CR11(T) (=NCCB 100125(T)=LMG 23727(T)).     

Aeromonas tecta sp. nov., isolated from clinical and environmental sources

Five Aeromonas strains, isolated from both clinical and environmental sources and characterized by a polyphasic approach, including phylogenetic analysis derived from gyrB, rpoD, and 16S rRNA gene sequencing, as well as DNA-DNA hybridization, extensive biochemical and antibiotic susceptibility tests, were recognized as members of an unknown, or undescribed, Aeromonas species. These "Aeromonas eucrenophila-like" strains were closely related to the species A. eucrenophila and Aeromonas encheleia, but they were negative for indole and acid from glycerol tests. Therefore, based on the results of the phylogenetic analyses and DNA-DNA pairing data of these strains, a novel species of the genus Aeromonas is described, for which the name Aeromonas tecta is proposed with isolate F518(T) (CECT7082(T), DSM17300(T), MDC91(T)) as the type strain.     

Description of Gibbsiella quercinecans gen. nov., sp. nov., associated with Acute Oak Decline

Gram-negative, facultatively anaerobic bacterial strains were consistently isolated from oak trees displaying symptoms of extensive stem bleeding. In Britain, this disorder is called Acute Oak Decline (AOD). A similar condition has been noted on species of Mediterranean oak in Spain. The identity of bacterial isolates from symptomatic trees in both countries was investigated using molecular techniques and phenotypic assays. 16S rRNA gene sequencing indicated that the strains were most closely related to the genera Serratia, Kluyvera, Klebsiella and Raoultella (all>97%). Phylogenetic analysis revealed that the strains formed a distinct lineage within the family Enterobacteriaceae, which was confirmed by both gyrB- and rpoB-gene sequencing. DNA-DNA hybridization confirmed that the strains belonged to a single taxon which could also be differentiated phenotypically from its closest phylogenetic neighbours. The phylogenetic and phenotypic data both demonstrated that the strains isolated from oak represented a novel genus and species within the family Enterobacteriaceae for which the name Gibbsiella quercinecans gen. nov., sp. nov. (type strain=FRB 97(T)=LMG 25500(T)=NCPPB 4470(T)) is proposed.     

Nakamurella panacisegetis sp. nov. and proposal for reclassification of Humicoccus flavidus Yoon et al., 2007 and Saxeibacter lacteus Lee et al., 2008 as Nakamurella flavida comb. nov. and Nakamurella lactea comb. nov

A novel actinobacterial strain, designated P4-7(T), was isolated from soil of a ginseng field located in Geumsan County, Korea. Cells of the strain were aerobic, Gram-stain-positive, non-motile, short rods. The isolate contained MK-8(H(4)) as the predominant menaquinone, iso-C(16:0), anteiso-C(15:0) and anteiso-C(17:0) as the major fatty acids, diphosphatidylglycerol, phosphatidylethanolamine and phosphatidylinositol as the major polar lipids, glucose, mannose, xylose, ribose and rhamnose as whole-cell sugars, and meso-diaminopimelic acid as the diagnostic diamino acid in the cell-wall peptidoglycan. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain P4-7(T) belongs to the family Nakamurellaceae and is most closely related to Nakamurella multipartita, Humicoccus flavidus and Saxeibacter lacteus (96.3, 97.0 and 96.4% similarity to the respective type strains). Based on comparative analyses of the 16S rRNA and rpoB gene sequences and chemotaxonomic data, it is proposed that H. flavidus and S. lacteus be transferred to the genus Nakamurella. Combined genotypic and phenotypic data also suggested that strain P4-7(T) be placed in a novel species of the genus Nakamurella, for which the name Nakamurella panacisegetis sp. nov. is proposed; the type strain is P4-7(T) (=KCTC 19426(T)=CECT 7604(T)).     

Neoscardovia arbecensis gen. nov., sp. nov., isolated from porcine slurries

Three Gram-positive, anaerobic, pleomorphic strains (PG10(T), PG18 and PG22), were selected among five strains isolated from pig slurries while searching for host specific bifidobacteria to track the source of fecal pollution in water. Analysis of the 16S rRNA gene sequence showed a maximum identity of 94% to various species of the family Bifidobacteriaceae. However, phylogenetic analyses of 16S rRNA and HSP60 gene sequences revealed a closer relationship of these strains to members of the recently described Aeriscardovia, Parascardovia and Scardovia genera, than to other Bifidobacterium species. The names Neoscardovia gen. nov. and Neoscardovia arbecensis sp. nov. are proposed for a new genus and for the first species belonging to this genus, respectively, and for which PG10(T) (CECT 8111(T), DSM 25737(T)) was designated as the type strain. This new species should be placed in the Bifidobacteriaceae family within the class Actinobacteria, with Aeriscardovia aeriphila being the closest relative. The prevailing cellular fatty acids were C(16:0) and C(18:1)ω9c, and the major polar lipids consisted of a variety of glycolipids, diphosphatidyl glycerol, two unidentified phospholipids, and phosphatidyl glycerol. The peptidoglycan structure was A1γmeso-Dpm-direct. The GenBank accession numbers for the 16S rRNA gene and HSP60 gene sequences of strains PG10(T), PG18 and PG22 are JF519691, JF519693, JQ767128 and JQ767130, JQ767131, JQ767133, respectively.     

Exiguobacterium mexicanum sp. nov. and Exiguobacterium artemiae sp. nov., isolated from the brine shrimp Artemia franciscana

Two Gram-positive strains isolated from cysts of the brine shrimp Artemia franciscana were subjected to a polyphasic taxonomic analysis. Based on 16S rRNA gene sequence comparison and composition of isoprenoid quinones, peptidoglycan and fatty acids, these organisms are members of the genus Exiguobacterium. Both strains showed 95.9% 16S rRNA gene sequence similarity to one another. The 16S rRNA gene sequences of strain 8N(T) and 9AN(T) were 97.5% and 98.9% similar to those of Exiguobacterium aurantiacum DSM 6208(T) and Exiguobacterium undae DSM 14481(T), respectively. Based on differences in chemotaxonomic and physiological characteristics, results of DNA-DNA hybridization and automated riboprinting, two novel species of the genus Exiguobacterium are proposed, Exiguobacterium mexicanum sp. nov. (type strain 8N(T)=DSM 16483(T)=CIP 108859(T)) and Exiguobacterium artemiae sp. nov. (type strain 9AN(T)=DSM 16484(T)=CIP 108858(T)).     

Molecular and phenotypic characterization of strains nodulating Anthyllis vulneraria in mine tailings, and proposal of Aminobacter anthyllidis sp. nov., the first definition of Aminobacter as legume-nodulating bacteria

Bacterial strains from Zn-Pb mine tailings were isolated by trapping with Anthyllis vulneraria, a legume-host suitable for mine substratum phytostabilisation. Sequence analysis of the 16S rRNA gene and three housekeeping genes (atpD, dnaK and recA) showed that they were related to those of the genus Aminobacter. DNA-DNA relatedness of representative isolates supported the placement of novel strains in Aminobacter as a new species. Phenotypic data emphasize their differentiation from the other related species of Aminobacter and Mesorhizobium. Aminobacter isolates exhibited nodA sequences tightly related with M. loti as the closest nodA relative. By contrast, their nodA sequences were highly divergent from those of M. metallidurans, another species associated with A. vulneraria that carries two complete copies of nodA. Therefore, the novel bacterial strains efficient on A. vulneraria represented the first occurrence of legume symbionts in the genus Aminobacter. They represent a new species for which the name Aminobacter anthyllidis sp. nov. is proposed (type strain STM4645(T)=LMG26462(T)=CFBP7437(T)).     

Identification of lactic acid bacteria from fermented tea leaves (miang) in Thailand and proposals of Lactobacillus thailandensis sp. nov., Lactobacillus camelliae sp. nov., and Pediococcus siamensis sp. nov

Eighteen rod-shaped homofermentatives, six heterofermentatives, and a coccal homofermentative lactic acid bacteria were isolated from fermented tea leaves (miang) produced in the northern part of Thailand. The isolates were placed in a monophyletic cluster consisting of Lactobacillus and Pediococcus species. They were divided into seven groups by phenotypic and chemotaxonomic characteristics, DNA-DNA similarity, and 16S rRNA gene sequences. Groups I to VI belonged to Lactobacillus and Group VII to Pediococcus. All of the strains tested produced DL-lactic acid but those in Group IV produced L-lactic acid. The strains tested in Groups I, II and V had meso-diaminopimelic acid in the cell wall. Six strains in Group I were identified as Lactobacillus pantheris; five strains in Group II as Lactobacillus pentosus; and four strains in Group V as Lactobacillus suebicus. Two strains in Group VI showed high DNA-DNA similarity for each other and MCH4-2 was closest to Lactobacillus fermentum CECT 562(T) with 99.5% of 16S rRNA gene sequence similarity. Five strains in Group III are proposed as Lactobacillus thailandensis sp. nov., and MCH5-2(T) (BCC 21235(T)=JCM 13996(T)=NRIC 0671(T)=PCU 272(T)) is the type strain which has 49 mol% G+C of DNA. Two strains in Group IV are proposed as Lactobacillus camelliae sp. nov., and the type strain is MCH3-1(T) (BCC 21233(T)=JCM 13995(T)=NRIC 0672(T)=PCU 273(T)) which has 51.9 mol% G+C of DNA. One strain in Group VII is proposed as Pediococcus siamensis sp. nov., and MCH3-2(T) (BCC 21234(T)=JCM 13997(T)=NRIC 0675(T)=PCU 274(T)) is the type strain which has 42 mol% G+C of DNA.     

Vibrio celticus sp. nov., a new Vibrio species belonging to the Splendidus clade with pathogenic potential for clams

A group of four motile facultative anaerobic marine isolates (Rd 8.15^T [=CECT 7224^T, =LMG 23850^T], Rd 16.13, Rd 6.8 [=LMG 25696] and Rd2L5) were obtained from cultured clams (Ruditapes philippinarum and Venerupis pullastra) in Galicia, north-western Spain. They formed a tight phylogenetic group based on sequences of the 16S rRNA gene and the four housekeeping genes rpoA (encoding the α-chain of RNA polymerase), rpoD (encoding the sigma factor of RNA polymerase), recA (encoding RecA protein), and atpA (encoding the α-subunit of bacterial ATP synthase). The phylogenies based on these sequences indicated that the four isolates represented a novel species in the genus Vibrio, and more precisely in the Splendidus clade. DNA–DNA hybridizations with the type strains of species showing more than 98.6% 16S rRNA gene sequence similarity, revealed a DNA–DNA relatedness below 70%. The isolates could be differentiated from the phylogenetically related Vibrio species on the basis of several phenotypic features. In addition, strain Rd 8.15^T showed potential pathogenic activity for adult clams in virulence assays. The name Vibrio celticus sp. nov. is proposed for this new taxon, with the type strain being Rd 8.15^T (=CECT 7224^T, =LMG 23850^T).     

Flavobacterium oncorhynchi sp. nov., a new species isolated from rainbow trout (Oncorhynchus mykiss)

Eighteen isolates of a Gram-negative, catalase and oxidase-positive, rod-shaped bacterium, recovered from diseased rainbow trout (Oncorhynchus mykiss), were characterized, using a polyphasic taxonomic approach. Studies based on comparative 16S rRNA gene sequence analysis showed that that the eighteen new isolates shared 99.2-100% sequence similarities. Phylogenetic analysis revealed that isolates from trout belonged to the genus Flavobacterium, showing the highest sequence similarities to F. chungangense (98.6%), F. frigidimaris (98.1%), F. hercynium (97.9%) and F. aquidurense (97.8%). DNA-DNA reassociation values between the trout isolates (exemplified by strain 631-08(T)) and five type strains of the most closely related Flavobacterium species exhibited less than 27% similarity. The G+C content of the genomic DNA was 33.0 mol%. The major respiratory quinone was observed to be menaquinone 6 (MK-6) and iso-C(15:0), C(15:0) and C(16:1) ω7c the predominant fatty acids. The polar lipid profile of strain 631-08(T) consisted of phosphatidylethanolamine, unknown aminolipids AL1 and AL3, lipids L1, L2, L3 and L4 and phospholipid PL1. The novel isolates were differentiated from related Flavobacterium species by physiological and biochemical tests. On the basis of the evidence from this polyphasic study, it is proposed that the isolates from rainbow trout be classified as a new species of the genus Flavobacterium, Flavobacterium oncorhynchi sp. nov. The type strain is 631-08(T) (= CECT 7678(T) = CCUG 59446(T)).
