The Stigma of Criminal Legal Involvement and Health: a Conceptual Framework.

The USA incarcerates more people than any other nation in the world. Exposure to the criminal legal system has been associated with a myriad of health outcomes but less is understood about what drives these associations. We argue that stigma due to criminal legal involvement, what we call criminal legal stigma, likely has a larger role in the association between incarceration and negative health outcomes than has been previously appreciated. There is limited research on the impact on health of criminal legal stigma despite abundant research on its negative social consequences. In this paper, we describe a conceptual framework of the health effects of criminal legal stigma drawing on previous research of criminal legal stigma and advances in other areas of stigma research. We outline key concepts related to stigma mechanisms, how they function at structural and individual levels, and how they might cause health outcomes. Finally, we identify potential areas for future research and opportunities for clinical interventions to remediate negative effects of stigma.

Critical parameters in cultivation of experimental biofilms using the example of Pseudomonas fluorescens.

Formation and treatment of biofilms present a great challenge for health care and industry. About 80% of human infections are associated with biofilms including biomaterial centered infections, like infections of prosthetic heart valves, central venous catheters, or urinary catheters. Additionally, biofilms can cause food and drinking water contamination. Biofilm research focusses on application of experimental biofilm models to study initial adherence processes, to optimize physico-chemical properties of medical materials for reducing interactions between materials and bacteria, and to investigate biofilm treatment under controlled conditions. Exploring new antimicrobial strategies plays a key role in a variety of scientific disciplines, like medical material research, anti-infectious research, plant engineering, or wastewater treatment. Although a variety of biofilm models exist, there is a lack of standardization for experimental protocols, and designing experimental setups remains a challenge. In this study, a number of experimental parameters critical for material research have been tested that influence formation and stability of an experimental biofilm using the non-pathogenic model strain of Pseudomonas fluorescens. These parameters include experimental time frame, nutrient supply, inoculum concentration, static and dynamic cultivation conditions, material properties, and sample treatment during staining for visualization of the biofilm. It was shown, that all tested parameters critically influence the experimental biofilm formation process. The results obtained in this study shall support material researchers in designing experimental biofilm setups.

Culicoidibacter larvae gen. nov., sp. nov., from the gastrointestinal tract of the biting midge (Culicoides sonorensis) larva, belongs to a novel lineage Culicoidibacteraceae fam. nov., Culicoidibacterales ord. nov. and Culicoidibacteria classis nov. of the phylum Firmicutes.

Strain CS-1T, a novel facultative anaerobic bacterium, was isolated from the larval gastrointestinal tract of the biting midge, Culicoides sonorensis, a vector of the epizootic haemorrhagic disease virus and the bluetongue virus. Cells were Gram-stain-positive, non-motile, non-spore-forming, pleomorphic rods. Optimal growth occurred at pH 7.5 and 37 °C. The G+C content of the genomic DNA was 38.3 mol%, estimated by using HPLC. The dominant cellular fatty acids were C14 : 0 (45.9 %) and C16 : 0 (26.6 %). The polar lipid profile comprised glycolipids, diphosphatidylglycerol, phospholipids and phosphoglycolipids. Respiratory quinones were not detected. Strain CS-1T had very low 16S rRNA gene similarity to members of the phylum Firmicutes: Macrococcus canis KM45013T (85 % similarity) and Turicibacter sanguinis MOL361T (88 % similarity). Phylogenetic analysis based on 16S rRNA, rpoB, gyrB genes, and conserved protein sequences of the whole genome revealed that strain CS-1T was related to members of the classes Bacilli and Erysipelotrichia within the phylum Firmicutes. Furthermore, average nucleotide identity and digital DNA-DNA hybridization analyses of the whole genome revealed very low sequence similarity to species of Bacilli and Erysipelotrichaceae (Macrococcus canis KM45013T and Turicibacter sp. H121). These results indicate that strain CS-1T belongs to the phylum Firmicutes and represents a new species of a novel genus, family, order and class. Based on the phenotypic, chemotaxonomic, phylogenetic and genomic characteristics, we propose the novel taxon Culicoidibacter larvae gen. nov., sp. nov. with the type strain CS-1T (=CCUG 71726T=DSM 106607T) within the hereby new proposed novel family Culicoidibacteraceae fam. nov., new order Culicoidibacaterales ord. nov. and new class Culicoidibacteria classis nov. in the phylum Firmicutes.

Nocardia macrotermitis sp. nov. and Nocardia aurantia sp. nov., isolated from the gut of the fungus-growing termite Macrotermes natalensis.

The taxonomic positions of two novel aerobic, Gram-stain-positive Actinobacteria, designated RB20T and RB56T, were determined using a polyphasic approach. Both were isolated from the fungus-farming termite Macrotermes natalensis. Results of 16S rRNA gene sequence analysis revealed that both strains are members of the genus Nocardia with the closest phylogenetic neighbours Nocardia miyunensis JCM12860T (98.9 %) and Nocardia nova DSM44481T (98.5 %) for RB20T and Nocardia takedensis DSM 44801T (98.3 %), Nocardia pseudobrasiliensis DSM 44290T (98.3 %) and Nocardia rayongensis JCM 19832T (98.2 %) for RB56T. Digital DNA-DNA hybridization (DDH) between RB20T and N. miyunensis JCM12860T and N. nova DSM 44481T resulted in similarity values of 33.9 and 22.0 %, respectively. DDH between RB56T and N. takedensis DSM44801T and N. pseudobrasiliensis DSM44290T showed similarity values of 20.7 and 22.3 %, respectively. In addition, wet-lab DDH between RB56T and N. rayongensis JCM19832T resulted in 10.2 % (14.5 %) similarity. Both strains showed morphological and chemotaxonomic features typical for the genus Nocardia, such as the presence of meso-diaminopimelic acid (A2pm) within the cell wall, arabinose and galactose as major sugar components within whole cell-wall hydrolysates, the presence of mycolic acids and major phospholipids (diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylinositol), and the predominant menaquinone MK-8 (H4, ω-cyclo). The main fatty acids for both strains were hexadecanoic acid (C16 : 0), 10-methyloctadecanoic acid (10-methyl C18 : 0) and cis-9-octadecenoic acid (C18 : 1 ω9c). We propose two novel species within the genus Nocardia: Nocardia macrotermitis sp. nov. with the type strain RB20T (=VKM Ac-2841T=NRRL B65541T) and Nocardia aurantia sp. nov. with the type strain RB56T (=VKM Ac-2842T=NRRL B65542T).

Actinomadura rubteroloni sp. nov. and Actinomadura macrotermitis sp. nov., isolated from the gut of the fungus growing-termite Macrotermes natalensis.

The taxonomic positions of two novel aerobic, Gram-positive actinobacteria, designated strains RB29T and RB68T, were determined using a polyphasic approach. Based on 16S rRNA gene sequence analysis, the closest phylogenetic neighbours of RB29T were identified as Actinomadura rayongensis DSM 102126T (99.2 % similarity) and Actinomadura atramentaria DSM 43919T (98.7 %), and for strain RB68T was Actinomadura hibisca DSM 44148T (98.3 %). Digital DNA-DNA hybridization (dDDH) between RB29T and its closest phylogenetic neighbours, A. rayongensis DSM 102126T and A. atramentaria DSM 43919T, resulted in similarity values of 53.2 % (50.6-55.9 %) and 26.4 % (24.1-28.9 %), respectively. Additionally, the average nucleotide identity (ANI) was 93.2 % (94.0 %) for A. rayongensis DSM 102126T and 82.3 % (78.9 %) for A. atramentaria DSM 43919T. dDDH analysis between strain RB68T and A. hibisca DSM 44148T gave a similarity value of 24.5 % (22.2-27.0 %). Both strains, RB29T and RB68T, revealed morphological characteristics and chemotaxonomic features typical for the genus Actinomadura, such as the presence of meso-diaminopimelic acid in the cell wall, galactose and glucose as major sugar components within whole-cell hydrolysates and the absence of mycolic acids. The major phospholipids were diphosphatidylglycerol, phosphatidylglycerol, phosphatidylinositol and phosphatidylinositol mannoside. Predominant menaquinones were MK-9(H6) and MK-9(H8) for RB29T and MK-9(H4) and MK-9(H6) for RB68T. The main fatty acids were identified as 10-methyloctadecanoic acid (10-methyl C18:0), 14-methylpentadecanoic acid (iso-C16:0), hexadecanoic acid (C16:0) and cis-9-octadecanoic acid (C18 : 1 ω9c). Here, we propose two novel species of the genus Actinomadura: Actinomadura rubteroloni sp. nov. with the type strain RB29T (=CCUG 72668T=NRRL B-65537T) and Actinomadura macrotermitis sp. nov. with the type strain RB68T (=CCUG 72669T=NRRL B-65538T).

Streptomyces smaragdinus sp. nov., isolated from the gut of the fungus growing-termite Macrotermes natalensis.

The taxonomic position of a novel aerobic, Gram-positive actinobacteria, designated strain RB5T, was determined using a polyphasic approach. The strain, isolated from the gut of the fungus-farming termite Macrotermes natalensis, showed morphological, physiological and chemotaxonomic properties typical of the genus Streptomyces. Based on 16S rRNA gene sequence analysis, the closest phylogenetic neighbour of RB5T was Streptomyces polyrhachis DSM 42102T (98.87 %). DNA-DNA hybridization experiments between strain RB5T and S. polyrhachis DSM 42102T resulted in a value of 27.4 % (26.8 %). The cell wall of strain RB5T contained ll-diaminopimelic acid as the diagnostic amino acid. Mycolic acids and diagnostic sugars in whole-cell hydrolysates were not detected. The strain produced the following major phospholipids: diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylinositol, phosphatidylinositol-mannoside and phosphatidylserine. The menaquinone profile showed hexa- and octahydrogenated menaquinones containing nine isoprene units [MK-9(H6) and MK-9(H8)]. The strain exhibited a fatty acid profile containing the following major fatty acids: 12-methyltridecanoic acid (iso-C14 : 0) 12-methyltetradecanoic acid (anteiso-C15 : 0), 13-methyltetradecanoic acid (iso-C15 : 0) and 14-methylpentadecanoic acid (iso-C16 : 0). Here, we propose a novel species of the genus Streptomyces - Streptomyces smaragdinus with the type strain RB5T (=VKM Ac-2839T=NRRL B65539T).

A polyphasic approach leads to seven new species of the cellulose-decomposing genus Sorangium, Sorangium ambruticinum sp. nov., Sorangium arenae sp. nov., Sorangium bulgaricum sp. nov., Sorangium dawidii sp. nov., Sorangium kenyense sp. nov., Sorangium orientale sp. nov. and Sorangium reichenbachii sp. nov.

Seventy-three strains of Sorangium have been isolated from soil samples collected from all over the world. The strains were characterized using a polyphasic approach and phenotypic, genotypic and chemotype analyses clarified their taxonomic relationships. 16S rRNA, xynB1, groEL1, matrix-assisted laser desorption/ioniziation time-of-flight mass spectrometry and API-ZYM analyses were conducted. In addition, from selected representative strains, fatty acids, quinones and phospholipids were analysed. In silico DNA-DNA hybridization and DNA-DNA hybridization against the current type species of Sorangiumcellulosum strain Soce 1871T (DSM 14627T) completed the analyses. Finally, our study revealed seven new species of Sorangium: Sorangium ambruticinum (Soce 176T; DSM 53252T, NCCB 100639T, sequence accession number ERS2488998), Sorangium arenae (Soce 1078T; DSM 105768T, NCCB 100643T, ERS2489002), Sorangium bulgaricum (Soce 321T; DSM 53339T, NCCB 100640T, ERS2488999), Sorangium dawidii (Soce 362T; DSM 105767T, NCCB 100641T, ERS2489000), Sorangium kenyense (Soce 375T; DSM 105741T, NCCB 100642T, ERS2489001), Sorangium orientale (Soce GT47T; DSM 105742T, NCCB 100638T, ERS2501484) and Sorangium reichenbachii (Soce 1828T; DSM 105769T, NCCB 100644T, ERS2489003).

Taxonomic analyses of members of the Streptomyces cinnabarinus cluster, description of Streptomyces cinnabarigriseus sp. nov. and Streptomyces davaonensis sp. nov.

Roseoflavin is the only known riboflavin (vitamin B2) analog with antibiotic properties. It is actively taken up by many micro-organisms and targets flavinmononucleotide riboswitches and flavoproteins. It is described as the product of the tentatively named 'Streptomyces davawensis' JCM 4913. Taxonomic analysis of this strain with a polyphasic approach showed that it is very closely related to Streptomyces cinnabarinus (DSM 40467). The two Streptomyces isolates were obtained from different geographical locations (the Philippines and the Kamchatka Peninsula, respectively), their genomes have been sequenced and the question was whether or not the two isolates were representatives of the same species. As we also worked with another isolate of Streptomyces cinnabarinus JS 360, the producer of the cinnabaramides, we wanted to clarify the taxonomic position of the three isolates by using a polyphasic approach. After analysis of the 16S rRNA gene sequence, we found in total 23 species of the genus Streptomyces that showed a similarity higher than 98.5 % to the three strains. We showed that 'S. davawensis' JCM 4913 and S. cinnabarinus DSM 40467 were very closely related but belong to two different species. Hence, we validate 'S. davawensis' as Streptomyces davaonensis sp. nov. with the type strain JCM 4913T (=DSM 101723T). In addition, the cinnabaramide producer can be clearly differentiated from S. davaonensis and this isolate is described as Streptomyces cinnabarigriseus sp. nov. with strain JS360T (=NCCB 100590T=DSM 101724T) as the type strain.

Herpetosiphon gulosus sp. nov., a filamentous predatory bacterium isolated from sandy soil and Herpetosiphon giganteus sp. nov., nom. rev.

Three filamentous gliding bacteria from the German Collection of Microorganisms and Cell Cultures, Hp g11, Hp g471 and Hp g472, were subjected to a phylogenetic analysis. These organisms had previously been classified as members of the genus Herpetosiphon based on their growth physiology and morphology. However, a taxonomic assignment at the species level had not been carried out. Analysis of 16S rRNA sequences now confirmed the close relationship of strain Hp g472 to Herpetosiphon aurantiacus DSM 785T (98.6 % nucleotide identity) and Herpetosiphon geysericola DSM 7119T (97.7 %). The results of DNA-DNA hybridization experiments further implied that strain Hp g472 should be classified as a distinct species. The DNA G+C content of strain Hp g472 was 49.9 mol%. The major quinone was MK-10 and the predominant cellular fatty acids were C18 : 1, C16 : 1 and C16 : 0. Based on phenotypic, chemotaxonomic and phylogenetic data it was concluded that strain Hp g472 represents a novel species of the genus Herpetosiphon, for which the name Herpetosiphon gulosus sp. nov. is proposed. The type strain is Hp g472T (=DSM 52871T=NBRC 112829T). In contrast to Hp g472T, the strains Hp g11 and Hp g471 exhibited closest 16S rRNA gene sequence similarity (>99 %) with 'Herpetosiphon giganteus' Hp a2. The distinctive genotypic and phenotypic properties of the latter supported the revival of the name as Herpetosiphon giganteus (ex Reichenbach & Golecki, 1975) sp. nov., nom. rev. We propose the previously deposited reference strain DSM 589T=NBRC 112828T as the type strain.

'Streptomyces caelicus', an antibiotic-producing species of the genus Streptomyces, and Streptomyces canchipurensis Li et al. 2015 are later heterotypic synonyms of Streptomyces muensis Ningthoujam et al. 2014.

'Streptomyces caelicus' DSM 40835 was first reported as the producer of the antibiotic griselimycin by some coworkers of Rhone Poulenc in 1971. The project on isolation of the antibiotic compound was stopped because of the bad solubility and selectivity of the compound towards Mycobacteria. At Sanofi-Aventis, Germany, the project was re-evaluated in 2007 and the gene cluster of griselimycin could be identified, characterized and was patented in 2013. At this time, 'S. caelicus' was an invalid name. During the strain characterization work, it was found that 'S. caelicus' belongs to the group of species of the genus Streptomyces which show an unusual heterogeneity of the 16S rRNA gene sequences. However, high 16S rRNA gene sequence similarities to Streptomyces muensis JCM 17576T and Streptomyces canchipurensis JCM 17575T were obvious. Here, we present a comparative description of 'Streptomyces caelicus' DS 9461 (=DSM 40835=NCCB 100592) with S. muensis and S. canchipurensis by use of a polyphasic taxonomy approach and additional comparison of some housekeeping genes by multilocus sequence analysis (MLSA). An emended description of Streptomyces muensis is provided as a result of this work.

Isoptericola cucumis sp. nov., isolated from the root tissue of cucumber (Cucumis sativus).

A Gram-stain-positive, aerobic organism, showing an irregular cell morphology, was isolated from the root tissue of cucumber (Cucumis sativus) and investigated in detail for its taxonomic position. On the basis of the 16S rRNA gene sequence analysis, strain AP-38T was shown to be most closely related to Isoptericola variabilis (99.1 %) and Isoptericola nanjingensis (98.9 %). The 16S rRNA gene sequence similarity to all other species of the genus Isoptericola was ≤98.5 %. DNA-DNA relatedness to Isoptericola variablis DSM 10177T and Isoptericola nanjingensis DSM 24300T was 31(reciprocal 41 %) and 34 (reciprocal 34 %), respectively. The diagnostic diamino acid of the peptidoglycan was l-lysine. The quinone system contained predominantly menaquinones MK-9(H4) and MK-9(H2). In the polar lipid profile, major compounds were diphosphatidylglycerol, phosphatidylglycerol, phosphatidylinositol and two phosphatidylinositol mannosides. The polyamine pattern contained the major components spermidine and spermine and significant amounts of tyramine. In the fatty acid profile, anteiso-C15 : 0 and iso-C15 : 0 were present in major amounts. These data support the allocation of the strain to the genus Isoptericola. The results of physiological and biochemical characterization additionally provide phenotypic differentiation of strain AP-38T from I. variabilis and I. nanjingensis. AP-38T represents a novel species of the genus Isoptericola, for which we propose the name Isoptericola cucumis sp. nov., with AP-38T (= LMG 29223T=CCM 8653T) as the type strain.

Novosphingobium gossypii sp. nov., isolated from Gossypium hirsutum.

A Gram-stain-negative, rod-shaped, non-spore-forming bacterium (strain JM-1396(T)) producing a yellow pigment, was isolated from the healthy internal stem tissue of post-harvest cotton (Gossypium hirsutum, cultivar 'DES-119') grown at the Plant Breeding Unit at the E.V. Smith Research Center in Tallassee (Macon county), AL, USA. 16S rRNA gene sequence analysis of strain JM-1396(T) showed high sequence similarity values to the type strains of Novosphingobium mathurense, Novosphingobium panipatense (both 98.6%) and Novosphingobium barchaimii (98.5%); sequence similarities to all other type strains of species of the genus Novosphingobium were below 98.3%. DNA-DNA pairing experiments of the DNA of strain JM-1396(T) and N. mathurense SM117(T), N. panipatense SM16(T) and N. barchaimii DSM 25411(T) showed low relatedness values of 8% (reciprocal 7%), 24% (reciprocal 26%) and 19% (reciprocal 25%), respectively. Ubiquinone Q-10 was detected as the dominant quinone; the fatty acids C18 : 1ω7c (71.0%) and the typical 2-hydroxy fatty acid, C14 : 0 2-OH (11.7%), were detected as typical components. The polar lipid profile contained the diagnostic lipids diphosphatidylglycerol, phosphatidylethanolamine, sphingoglycolipid and phosphatidylcholine. The polyamine pattern contained the major compound spermidine and only minor amounts of other polyamines. All these data revealed that strain JM-1396(T) represents a novel species of the genus Novosphingobium. For this reason we propose the name Novosphingobium gossypii sp. nov. with the type strain JM-1396(T) ( = LMG 28605(T) = CCM 8569(T) = CIP 110884(T)).

Proposal of Novosphingobium rhizosphaerae sp. nov., isolated from the rhizosphere.

A yellow, Gram-stain-negative, rod-shaped, non-spore-forming bacterium (strain JM-1(T)) was isolated from the rhizosphere of a field-grown Zea mays plant in Auburn, AL, USA. 16S rRNA gene sequence analysis of strain JM-1(T) showed high sequence similarity to the type strains of Novosphingobium capsulatum (98.9%), Novosphingobium aromaticivorans (97.4%), Novosphingobium subterraneum (97.3%) and Novosphingobium taihuense (97.1%); sequence similarities to all other type strains of species of the genus Novosphingobium were below 97.0%. DNA-DNA hybridizations of strain JM-1(T) and N. capsulatum DSM 30196(T), N. aromaticivorans SMCC F199(T) and N. subterraneum SMCC B0478(T) showed low similarity values of 33% (reciprocal: 21%), 14% (reciprocal 16%) and 36% (reciprocal 38%), respectively. Ubiquinone Q-10 was detected as the major respiratory quinone. The predominant fatty acid was C18:1ω7c (71.0%) and the typical 2-hydroxy fatty acid C14:0 2-OH (11.7%) was detected. The polar lipid profile contained the diagnostic lipids diphosphatidylglycerol, phosphatidylethanolamine, sphingoglycolipid and phosphatidylcholine. Characterization by 16S rRNA gene sequence analysis, physiological parameters, pigment analysis, and ubiquinone, polar lipid and fatty acid composition revealed that strain JM-1(T) represents a novel species of the genus Novosphingobium. For this species we propose the name Novosphingobium rhizosphaerae sp. nov. with the type strain JM-1(T) ( = LMG 28479(T) =CCM 8547(T)).

Possibility of death sentence has divergent effect on verdicts for Black and White defendants.

When anticipating the imposition of the death penalty, jurors may be less inclined to convict defendants. On the other hand, minority defendants have been shown to be treated more punitively, particularly in capital cases. Given that the influence of anticipated sentence severity on verdicts may vary as a function of defendant race, the goal of this study was to test the independent and interactive effects of these factors. We conducted a survey-embedded experiment with a nationally representative sample to examine the effect on verdicts of sentence severity as a function of defendant race, presenting respondents with a triple murder trial summary that manipulated the maximum penalty (death vs. life without parole) and the race of the defendant. Respondents who were told life-without-parole was the maximum sentence were not significantly more likely to convict Black (67.7%) than White (66.7%) defendants. However, when death was the maximum sentence, respondents presented with Black defendants were significantly more likely to convict (80.0%) than were those with White defendants (55.1%). The results indicate that the death penalty may be a cause of racial disparities in criminal justice, and implicate threats to civil rights and to effective criminal justice.

Emended description of Actinoplanes friuliensis and description of Actinoplanes nipponensis sp. nov., antibiotic-producing species of the genus Actinoplanes.

In 2000, an actinomycete strain that showed strong antibacterial activity in culture extracts was isolated from a soil sample. The antibiotic activity corresponds to a lipopeptide complex that was named friulimycin, as the producing micro-organism was isolated from a soil sample from the region of Friaul in Italy. Taxonomic investigations showed that the producer strain belonged to a novel species of the genus Actinoplanes, for which the name Actinoplanes friuliensis was proposed. During further taxonomic studies, another antibiotic-producing isolate belonging to the genus Actinoplanes, FH 2241(T), was characterized; in a patent, the name 'Actinoplanes nipponensis' was proposed for this strain. This organism was shown to be related to A. friuliensis. 'A. nipponensis' was never described in detail and the name was never validly published. Here we present a complete description of Actinoplanes nipponensis sp. Nov. (type strain FH 2241(T) = ATCC 31145(T) = DSM 43867(T)) and an emended description of Actinoplanes friuliensis (type strain HAG 010964(T) = DSM 45797(T) = CCUG 63250(T)).

Genomics-guided discovery of endophenazines from Kitasatospora sp. HKI 714.

In this study we report on the genomics-guided exploration of the metabolic potential of the newly discovered strain Kitasatospora sp. HKI 714. The bioinformatics analysis of the whole genome sequence revealed the presence of a biosynthetic gene cluster presumably responsible for the biosynthesis of formerly unknown endophenazine derivatives. A 200 L cultivation combined with bioactivity-guided isolation techniques revealed four new natural products belonging to the endophenazines and the 5,10-dihydrophenazines. Detailed descriptions of their biological effects, mainly focused on antimicrobial properties against several mycobacteria, are given.

Kaistia hirudinis sp. nov., isolated from the skin of Hirudo verbana.

A Gram-negative, rod-shaped bacterium was isolated from the skin of the medical leech Hirudo verbana and studied for its taxonomic allocation. 16S rRNA gene sequence similarities to other strains showed that the strain was closely related to species of the genus Kaistia. Kaistia geumhonensis was shown to be the most closely related species (96.8%), followed by Kaistia soli (96.6%) and Kaistia dalseonensis (96.2%). All other species of the genus Kaistia showed 16S rRNA gene sequence similarities <96%. Chemotaxonomic data for strain E94(T) (major ubiquinone: Q-10; major polar lipids: diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, hydroxyphosphatidylethanolamine, phosphatidylserine, unknown phospholipids, aminolipids and aminophospholipids; and major fatty acids: C(18:1)ω7c, C(19:0)ω8c cylco, C(16:0) and C(18:0)) supported the affiliation of the isolate to the genus Kaistia. Phenotypic differentiation of strain E94(T) from all species of the genus Kaistia was possible using different physiological characters. Strain E94(T) represents a novel species of the genus Kaistia, for which the name Kaistia hirudinis sp. nov. is proposed, with the type strain E94(T) ( = LMG 26925(T) =CIP 110381(T) =CCM 8401(T)).

Lysinibacillus contaminans sp. nov., isolated from surface water.

A Gram-positive-staining, aerobic, endospore-forming bacterium, isolated as a contamination from an enrichment of enteric bacteria from surface water, was studied using a polyphasic taxonomic approach. 16S rRNA gene sequence similarity comparisons revealed that strain FSt3A(T) was grouped in the genus Lysinibacillus, most closely related to Lysinibacillus xylanilyticus XDB9(T) (98.1%), Lysinibacillus parviboronicapiens BAM-582(T) and Lysinibacillus sphaericus DSM 28(T) (both 98.0%). The 16S rRNA gene sequence similarity to other species of the genus Lysinibacillus was <97.5%. The allocation to the genus Lysinibacillus was supported by a detailed chemotaxonomic characterization revealing a cell wall containing alanine, glutamic acid, aspartic acid and the diagnostic diamino acid lysine in a molar ratio of 1.6:1:0.9:0.8 (peptidoglycan type A4α), the major menaquinones MK-7 and MK-6, and polar lipids consisting of diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol, four unknown phospholipids, one unknown aminophospholipid and one unidentified aminolipid. The major fatty acids were iso- and anteiso-branched fatty acids. DNA-DNA hybridizations with the type strains of the most closely related species, L. parviboronicapiens DSM 25242(T), L. xylanilyticus DSM 23493(T) and L. sphaericus DSM 28(T), in addition to the results of physiological and biochemical tests, allowed genotypic and phenotypic differentiation of strain FSt3A(T) from these related species. Thus, FSt3A(T) represents a novel species of the genus Lysinibacillus, for which the name Lysinibacillus contaminans sp. nov. is proposed, with FSt3A(T) ( =CCM 8383(T) =DSM 25560(T) =CIP 110362(T)) as the type strain.

Castellaniella hirudinis sp. nov., isolated from the skin of Hirudo verbana.

A Gram-staining-negative, rod-shaped, non-spore-forming bacterium, designated strain E103(T), was isolated from the skin of the medical leech Hirudo verbana. 16S rRNA gene sequence analysis showed that the isolate was closely related to species of the genus Castellaniella. Castellaniella ginsengisoli DCY36(T) was shown to be the most closely related (98.4 % 16S rRNA gene sequence similarity), followed by Castellaniella denitrificans NKNTAU(T) and Castellaniella daejeonensis MJ06(T) (both 97.8 %), then Castellaniella caeni Ho-11(T) (97.5 %). Chemotaxonomic data (major ubiquinone, Q-8; major polar lipids, phosphatidylethanolamine, phosphatidylglycerol and phosphatidylserine; predominant polyamine, putrescine with a moderate amount of 2-hydroxyputrescine; and major fatty acids, C(17 : 0) cyclo, C(16 : 0) and summed feature 4 comprising C(16 : 1)ω7c and/or iso-C(15 : 0) 2-OH) supported the affiliation of the isolate to the genus Castellaniella. DNA-DNA hybridization values with the type strains of all species of the genus Castellaniella were 23 % (reciprocal, 18 %) with C. ginsengisoli KCTC 22398(T), 20 % (26 %) with C. daejeonensis KCTC 22454(T), 11 % (58 %) with C. denitrificans DSM 11046(T) and 13 % (12 %) with C. caeni KCTC 12197(T)(.) Phenotypic differentiation of strain E103(T) from its closest neighbours was possible. Strain E103(T) therefore represents a novel species of the genus Castellaniella, for which the name Castellaniella hirudinis sp. nov. is proposed, with the type strain E103(T) ( = CCUG 62394(T) = LMG 26910(T)).

Alicyclobacillus consociatus sp. nov., isolated from a human clinical specimen.

A Gram-stain-positive, aerobic organism, isolated from a blood sample from a 51-year-old woman, was studied for its taxonomic position. Based on 16S rRNA gene sequence similarity comparisons, strain CCUG 53762(T) was grouped into the genus Alicyclobacillus, most closely related to the type strain of Alicyclobacillus pohliae (94.7 %). The 16S rRNA gene sequence similarity to other species of the genus Alicyclobacillus was ≤91 % and similarity to species of the genus Tumebacillus was 91.3-93 %. The occurrence of menaquinone MK-7 as the major respiratory quinone, meso-diaminopimelic acid as the diagnostic diamino acid of the cell wall and the fatty acid profile supported the allocation of the strain to the genus Alicyclobacillus. Major fatty acids were iso- and anteiso-branched fatty acids. The polar lipid profile consisted of diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine and three unknown phospholipids. The absence of the iso-branched fatty acids iso-C16 : 0 and iso-C17 : 0 allowed differentiation of strain CCUG 53762(T) from A. pohliae CIP 109385(T). In addition, the results of physiological and biochemical tests also allowed phenotypic differentiation of strain CCUG 53762(T) from this most closely related species. The G+C content of the DNA was 47 mol%. Strain CCUG 53762(T) therefore represents a novel species of the genus Alicyclobacillus, for which we propose the name Alicyclobacillus consociatus sp. nov., with CCUG 53762(T) ( = CCM 8439(T)) as the type strain.
