Pennell subsp. sivarajanii Dhruvan et Mohanan differs from L. ciliata subsp. ciliata by its creeping habit, rooting from almost all nodes, distant and sub‐aristate leaf serrations, upper lip of corolla almost equal in length to the lower lip and straight staminodes.     

Photorhabdus temperata subsp. stackebrandtii subsp. nov. (Enterobacteriales: Enterobacteriaceae)

The bacterial symbiont of the entomopathogenic nematode Heterorhabditis bacteriophora strain GPS11 was characterized by 16S rRNA gene sequence and physiological traits. The phylogenetic tree built upon 16S rRNA gene sequences clustered the GPS11 bacterial isolate with Photorhabdus temperata strains which have been previously isolated from Heterorhabditis species. The phylogenetic tree further identified four subgroups in P. temperata, and the relationships among these subgroups were confirmed by gyrase subunit B (gyrB) gene sequence analysis. The subgroup containing the GPS11 bacterial isolate differs from other subgroups in sequences of 16S rRNA and gyrB gene, physiological traits, nematode host species, and geographic origin. Therefore, the subgroup comprising the GPS11 bacterial isolate is proposed here as a new subspecies: Photorhabdus temperata subsp. stackebrandtii subsp. nov. (type strain GPS11). The type strain has been deposited in ATCC and DSMZ collections.     

Elevation of Francisella philomiragia subsp. noatunensisMikalsen et al. (2007) to Francisella noatunensis comb. nov. [syn. Francisella piscicida Ottem et al. (2008) syn. nov.] and characterization of Francisella noatunensis subsp. orientalis subsp. nov., two important fish pathogens

Aims: This study was conducted to clarify the taxonomic status of Francisella sp. strain Ehime‐1, a fish pathogen, in relation to the fish pathogens F. piscicida and F. philomiragia subsp. noatunensis and to F. philomiragia subsp. philomiragia. Methods and Results: Francisella sp. Ehime‐1 was compared to F. piscicida, F. philomiragia subsp. noatunensis and several F. philomiragia subsp. philomiragia isolates through sequencing of the 16S rRNA‐gene and several house‐keeping genes and determination of biochemical and phenotypic properties. Results show that F. piscicida is indistinguishable from F. philomiragia subsp. noatunensis by sequence and phenotypic traits. Francisella sp. Ehime‐1 and F. philomiragia subsp. noatunensis are clearly separated from F. philomiragia. Francisella sp. Ehime‐1 is biochemically, phenotypically and genetically different from F. philomiragia subsp. noatunensis (=F. piscicida), but DNA–DNA hybridization does not clearly support establishment as a separate species (level of relatedness 64% and 73·4%, mean 68·7%). Conclusions: We propose to elevate F. philomiragia subsp. noatunensis to species rank as F. noatunensis comb. nov., while F. piscicida is considered a heterotypic synonym of F. noatunensis comb. nov. Evidence suggests that Francisella sp. Ehime‐1 represents a novel subspecies of F. noatunensis, for which the name F. noatunensis subsp. orientalis subsp. nov. is proposed (=DSM21254^T, = LMG24544^T). Significance and Impact of the Study: This study contributes to the taxonomy and characteristics of fish‐pathogenic Francisella spp.     

Salinivibrio costicola subsp. alcaliphilus subsp. nov., a haloalkaliphilic aerobe from Campania Region (Italy)

Phenotypic and phylogenetic studies were performed on unidentified Gram-negative staining, haloalkaliphilic aerobe and protease producer Salinivibrio-like organism recovered from a saltish spring with algal mat in the “Pozzo del Sale” site (Salt's Well) in the Campania Region (South Italy). Phylogenetic analysis based on comparison of 16S rRNA gene sequences demonstrated that the isolate was related to species of Salinivibrio genus. The DNA–DNA hybridization of the type strain 18AG^T with the most related Salinivibrio costicola subsp. costicola showed a re-association value of 72%. Based on the phenotypic distinctiveness of 18AG^T strain and molecular, chemical and genetic evidence, it is proposed that strain 18AG^T can be classified as S. costicola subsp. alcaliphilus, subsp. nov. The type strain of S. costicola subsp. alcaliphilus, is ATCC BAA-952^T; DSM 16359^T.     

Xylella fastidiosa subspecies: X. fastidiosa subsp. [correction] fastidiosa [correction] subsp. nov., X. fastidiosa subsp. multiplex subsp. nov., and X. fastidiosa subsp. pauca subsp. nov

Xylella fastidiosa, a fastidious bacterium causing disease in over 100 plant species, is classified as a single species, although genetic studies support multiple taxons. To determine the taxonomic relatedness among strains of X. fastidiosa, we conducted DNA-DNA relatedness assays and sequenced the 16S-23S intergenic spacer (ITS) region using 26 strains from 10 hosts. Under stringent conditions (Tm -15 degrees C), the DNA relatedness for most X. fastidiosa strains was *70%. However, at high stringency (Tm -8 degrees C), three distinct genotypes (A, B, and C) were revealed. Taxon A included strains from cultivated grape, alfalfa, almond (two), and maple, interrelated by 85% (mean); taxon B included strains from peach, elm, plum, pigeon grape, sycamore, and almond (one), interrelated by 84%; and taxon C included only strains from citrus, interrelated by 87%. The mean reciprocal relatedness between taxons A and B, A and C, and B and C, were 58, 41, and 45%, respectively. ITS results also indicated the same grouping; taxons A and B, A and C, and B and C had identities of 98.7, 97.9, and 99.2%, respectively. Previous and present phenotypic data supports the molecular data. Taxon A strains grow faster on Pierce's disease agar medium whereas B and C strains grow more slowly. Taxon B and C strains are susceptible to penicillin and resistant to carbenicillin whereas A strains are opposite. Each taxon can be differentiated serologically as well as by structural proteins. We propose taxons A, B, and C be named X. fastidiosa subsp. fastidiosa [correction] subsp. nov, subsp. multiplex, subsp. nov., and subsp. pauca, subsp. nov., respectively. The type strains of the subspecies are subsp. fastidiosa [correction] ICPB 50025 (= ATTC 35879T and ICMP 15197), subsp. multiplex ICPB 50039 (= ATTC 35871 and ICMP 15199), and subsp. pauca ICPB 50031 (= ICMP 15198).

Vibrio tetraodonis subsp. pristinus subsp. nov., isolated from the coral Acropora cytherea at Palmyra Atoll,and creation and emended description of Vibrio tetraodonis subsp. tetraodonis subsp. nov

Strain OCN044^T was isolated from the homogenised tissue and mucus of an apparently healthy Acropora cytherea coral fragment collected from the western reef terrace of Palmyra Atoll in the Northern Line Islands and was taxonomically evaluated with a polyphasic approach. The morphological and chemotaxonomic properties are consistent with characteristics of the genus Vibrio: Gram-stain-negative rods, oxidase- and catalase-positive, and motile by means of a polar flagellum. Strain OCN044^T can be differentiated as a novel subspecies based on 21 differences among chemotaxonomic features (e.g., fatty acids percentages for C_12:0 and C_18:1 ω7c), enzymatic activities (e.g., DNase and cystine arylamidase), and carbon sources utilized (e.g., L-xylose and D-melezitose) from its nearest genetic relative. Phylogenetic analysis and genomic comparisons show close evolutionary relatedness to Vibrio tetraodonis A511^T but the overall genomic relatedness indices identify strain OCN044^T as a distinct subspecies. Based on a polyphasic characterisation, differences in genomic and taxonomic data, strain OCN044^T represents a novel subspecies of V. tetraodonis A511^T, for which the name Vibrio tetraodonis subsp. pristinus subsp. nov. is proposed. The type strain is OCN044^T (=?LMG 31895^T?=?DSM 111778^T).

     

Staphylococcus petrasii sp. nov. including S. petrasii subsp. petrasii subsp. nov. and S. petrasii subsp. croceilyticus subsp. nov., isolated from human clinical specimens and human ear infections

Thirteen coagulase-negative, oxidase-negative, and novobiocin-susceptible staphylococci were isolated from human clinical specimens. The isolates were differentiated from known staphylococcal species on the basis of 16S rRNA, hsp60, rpoB, dnaJ, tuf, and gap gene sequencing, automated ribotyping, (GTG)₅-PCR fingerprinting, and MALDI-TOF MS analysis. Phylogenetic analysis based on the 16S rRNA gene sequence indicated phylogenetic relatedness of the analyzed strains to Staphylococcus haemolyticus, Staphylococcus hominis, Staphylococcus devriesei, and Staphylococcus lugdunensis. DNA–DNA hybridization experiments between representative strains CCM 8418^T, CCM 8421^T, and the closest phylogenetic neighbors confirmed that the isolates represent novel Staphylococcus species, for which the name Staphylococcus petrasii sp. nov. is proposed. Genotypic and phenotypic analyses unambiguously split the strains into two closely related subclusters. Based on the results, two novel subspecies S. petrasii subsp. petrasii subsp. nov. and S. petrasii subsp. croceilyticus subsp. nov. are proposed, with type strains CCM 8418^T (=CCUG 62727^T) and CCM 8421^T (=CCUG 62728^T), respectively.     

Syntrophomonas wolfei subsp. methylbutyratica subsp. nov., and assignment of Syntrophomonas wolfei subsp. saponavida to Syntrophomonas saponavida sp. nov. comb. nov

A spore-forming bacterium strain 4J5(T) was isolated from rice field mud. When co-cultured with Methanobacterium formicicum DSM 1535(T), strain 4J5(T) could syntrophically degrade saturated fatty acids with 4-8 carbon atoms, including 2-methylbutyrate. Phylogenetic analysis based on 16S rRNA gene similarity showed that strain 4J5(T) was most closely related to Syntrophomonas wolfei subsp. wolfei DSM 2245(T) (98.9% sequence similarity); however, it differed from the latter in the substrates utilized and its genetic characteristics. Therefore, a new subspecies Syntrophomonas wolfei subsp. methylbutyratica is proposed. The type strain is 4J5(T) (=CGMCC 1.5051(T)=JCM 14075(T)). Furthermore, based on 16S rRNA sequence divergence and substrate utilization, we propose the assignment of Syntrophomonas wolfei subsp. saponavida DSM 4212(T) to Syntrophomonas saponavida sp. nov. comb. nov.
