Cloacibacterium normanense gen. nov., sp nov., a novel bacterium in the family Flavobacteriaceae isolated from municipal wastewater

Phenotypic and phylogenetic studies were performed on three isolates of an unknown Gram-negative, facultatively anaerobic, non-motile, yellow-pigmented, rod-shaped organism isolated from raw sewage. 16S rRNA gene sequence analysis indicated that these strains were members of the Bergeyella-Chryseobacterium-Riemerella branch of the family Flavobacteriaceae. The unknown bacterium was readily distinguished from reference strains by 16S rRNA gene sequencing and biochemical tests. The organism contained menaquinone MK-6 as the predominant respiratory quinone and had a DNA G + C content of 31 mol%. A most probable number-PCR approach was developed to detect, and estimate the numbers of, this organism. Untreated wastewater from one plant yielded an estimated count of 1.4 x 10(5) cells ml(-1), and untreated wastewater from a second plant yielded an estimated count of 1.4 x 10(4) cells ml(-1). Signal was not detected from treated effluent or from human stool specimens. On the basis of the results of the study presented, it is proposed that the unknown bacterium be classified in a novel genus Cloacibacterium, as Cloacibacterium normanense gen. nov., sp. nov., which is also the type species. The type strain of Cloacibacterium normanense is strain NRS1(T) (=CCUG 46293(T)=CIP 108613(T) =ATCC BAA-825(T) = DSM 15886(T)).

Actinomyces coleocanis sp. nov., from the vagina of a dog

A hitherto undescribed Actinomyces-like bacterium was isolated from the vagina of a dog. Biochemical testing and PAGE analysis of whole-cell proteins indicated that the isolate was phenotypically different from previously described Actinomyces species and related taxa. Sequencing of 165 rRNA showed that the unknown bacterium was distinct from all currently known Actinomyces species. Phylogenetically, the unidentified organism displayed a specific association with Actinomyces europaeus, but a sequence divergence of > 5% demonstrated that it represents a distinct species. Based on both phenotypic and 165 rRNA sequence considerations, it is proposed that the unknown strain from a dog be classified as a novel species, Actinomyces coleocanis sp. nov. The type strain is CCUG 41708T (= CIP 106873T).

Arcanobacterium hippocoleae sp. nov., from the vagina of a horse

A polyphasic taxonomic study was performed on a previously unidentified gram-positive, facultatively anaerobic, diphtheroid-shaped organism isolated from a vaginal discharge of a horse. Comparative 16S rRNA gene sequencing demonstrated that the strain was a member of the genus Arcanobacterium, but sequence divergence values of >4% with described species of this genus (viz: Arcanobacterium haemolyticum, Arcanobacterium bernardiae, Arcanobacterium phocae, Arcanobacterium pluranimalium and Arcanobacterium pyogenes) demonstrated that the isolate represented a novel species. The unknown bacterium was readily distinguished from other Arcanobacterium species by biochemical tests. Based on phylogenetic and phenotypic evidence, it is proposed that the unknown bacterium be classified as Arcanobacterium hippocoleae sp. nov. The type strain of A. hippocoleae is CCUG 44697T (= CIP 106850T).

Facklamia miroungae sp. nov., from a juvenile southern elephant seal (Mirounga leonina)

An unusual gram-positive, catalase-negative, facultatively anaerobic, coccus-shaped organism that originated from a juvenile elephant seal was characterized by phenotypic and molecular taxonomic methods. Comparative 16S rRNA gene sequencing showed that the unknown coccus represents a new subline within the genus Facklamia. The unknown strain was readily distinguishable from all currently recognized species of the genus Facklamia (Facklamia hominis, Facklamia languida, Facklamia ignava, Facklamia sourekii and Facklamia tabacinasalis) by biochemical tests and electrophoretic analysis of whole-cell proteins. Based on phylogenetic and phenotypic evidence, it is proposed that the unknown bacterium be classified as Facklamia miroungae sp. nov. The type strain of F. miroungae is CCUG 42728T (= CIP 106764T). F. miroungae is the first member of the genus Facklamia to be isolated from an animal other than man.

Actinomyces suimastitidis sp. nov., isolated from pig mastitis

An unusual Actinomyces-like bacterium originating from a pig with mastitis was subjected to a polyphasic taxonomic investigation. The morphological and biochemical characteristics of the organism were consistent with its preliminary assignment to the genus Actinomyces but it did not appear to correspond to any recognized species. PAGE analysis of whole-cell proteins confirmed the phenotypic distinctiveness of the bacterium and 16S rRNA gene sequence analysis demonstrated that it represents a hitherto unknown sub-line amongst a cluster of Actinomyces species which embraces Actinomyces canis, Actinomyces georgiae, Actinomyces hyovaginalis, Actinomyces meyeri, Actinomyces odontolyticus, Actinomyces radingae and Actinomyces turicensis. Based on phylogenetic and phenotypic evidence, it is proposed that the unknown bacterium isolated from pig mastitis be classified as Actinomyces suimastitidis sp. nov. The type strain of Actinomyces suimastitidis is CCUG 39279T (= CIP 106779T).

Corynebacterium capitovis sp. nov., from a sheep

An unknown Gram-positive rod-shaped bacterium was isolated from skin scrapings from the infected head of a sheep and subjected to a polyphasic taxonomic analysis. Chemical analysis revealed the presence of straight-chain and monounsaturated fatty acids and short-chain (C32-C36) mycolic acids consistent with the genus Corynebacterium. Comparative 16S rRNA gene sequencing confirmed that the unknown rod was a member of the genus Corynebacterium, with the organism forming a distinct sub-line and displaying greater than 3% sequence divergence with established species. The unknown Corynebacterium isolate was readily distinguished from recognized species of the genus by biochemical tests and electrophoretic analysis of whole-cell proteins. Based on phylogenetic and phenotypic evidence, it is proposed that the unknown bacterium from a sheep be classified in the genus Corynebacterium, as Corynebacterium capitovis sp. nov. The type strain of Corynebacterium capitovis is CCUG 39779T (= CIP 106739T).

Actinomyces catuli sp. nov., from dogs

An Actinomyces-like bacterium was recovered from two dogs. Based on cellular morphology and biochemical criteria, the unknown bacterium resembled the genus Actinomyces but it did not appear to correspond to any of the currently recognized species of this genus. PAGE analysis of whole-cell proteins confirmed that the strain was phenotypically distinct from all other Actinomyces species and comparative 16S rRNA gene sequencing showed that the bacterium represents an unknown sub-line within the genus. Based on phenotypic and phylogenetic evidence, it is proposed that the bacterium from dogs be classified as a new species of the genus Actinomyces, Actinomyces catuli. The type strain of Actinomyces catuli is CCUG 41709T (= CIP 106507T).

Characterization of Actinomyces isolates from samples from the human urogenital tract: description of Actinomyces urogenitalis sp. nov.

Three strains of a previously undescribed Actinomyces-like bacterium were isolated from human clinical sources (urine, urethra and vaginal secretion). Biochemical testing and PAGE analysis of whole-cell proteins indicated that the strains were phenotypically homogeneous and distinct from previously described Actinomyces and Arcanobacterium species. Comparative 16S rRNA gene sequencing studies showed the bacterium to be a hitherto unknown subline within a group of Actinomyces species which includes Actinomyces bovis, the type species of the genus. Based on phylogenetic and phenotypic evidence it is proposed that the unknown bacterium from humans be classified as Actinomyces urogenitalis sp. nov. The type strain of Actinomyces urogenitalis is CCUG 38702T (= CIP 106421T).

Actinomyces canis sp. nov., isolated from dogs

Three strains of a previously undescribed catalase-positive Actinomyces-like bacterium were isolated from dogs. Biochemical testing and PAGE analysis of whole-cell proteins indicated that the strains were phenotypically highly related to each other but different from previously described Actinomyces and Arcanobacterium species. Sequencing of 16S rRNA showed that the unknown bacterium represents a new subline within a cluster of species which includes Actinomyces hyovaginalis, Actinomyces georgiae, Actinomyces meyeri, Actinomyces odontolyticus, Actinomyces radingae and Actinomyces turicensis. On the basis of phenotypic evidence and 16S rRNA sequence divergence levels (greater than 5% with recognized Actinomyces species) it is proposed that the unknown strains from canine sources be classified as a new species with the name Actinomyces canis sp. nov. The type strain of Actinomyces canis is CCUG 41706T (= CIP 106351T).

The impact of social and relational contexts on innovation transfer in foreign subsidiaries

It is widely acknowledged that innovation is one of the pillars of multinational enterprises (MNEs) and that technological knowledge from different host locations is a key factor to the MNEs’ competitive advantages development. Concerning these assumptions, in this paper we aim to understand how the social and the relational contexts affect the conventional and reverse transfer of innovation from MNEs’ subsidiaries hosted in emerging markets. We analyzed the social context through the institutional profile (CIP) level and the relational context through trust and integration levels utilizing a survey sent to 172 foreign subsidiaries located in Brazil, as well as secondary data. Through an ordinary least squares regression (OLS) analysis we found that the relational context affects the conventional and reverse innovation transfer in subsidiaries hosted in emerging markets. We however did not find support for the social context effect.

The species is only known to occur in the Serra da Canastra National Park, located in the southwestern Minas Gerais, Brazil, and is morphologically related to V. atropurpurea Silveira from serra do Cipo, Espinhaco range.

Development of a heavy metal sorption system through the P=S functionalization of coconut (Cocos nucifera) fibers

Lignocellulosic residues are interesting materials for the production of heavy metal adsorbents for aquatic systems. Whole fibers taken from coconut (Cocos nucifera) husks were functionalized with the thiophosphoryl (P=S) group by means of the direct reaction with CI(3)P=S, (CH(3)O)(2)CIP=S or (CH(3)CH(2)O)(2)CIP=S in order to obtain an adsorptive system for `soft` metal ions, particularly Cd(2+). These functionalized fibers (FFs) were characterized by means of elemental analysis, infrared spectroscopy, thermal analysis and acid-base titration. Adsorption isotherms for Cd(2+) fitted the Langmuir model, with binding capacities of 0.2-5 mmol g(-1) of FF at 25 degrees C. (C) 2009 Elsevier Ltd. All rights reserved.

Märkskyltprogram för mättransformatorer

Detta examensarbete utfördes på ABB Power Technologies i Ludvika med syfte att förenkla tillverkningen av märkskyltar till mättransformatorer.Tidigare utformades alla skyltar för hand i Excel utifrån data från ett beräkningsprogram. Det gjorde att det behövdes en mall för varje variant i varje språk vilket ledde till väldigt många mallar. På ABB ville man både komma ifrån mängden olika mallar och det tidskrävande handarbetet som dessutom kunde resultera i att skyltarna inte fick enhetligt utseende. Genom att göra ett program som automatiskt genererar skyltarna utifrån en standardmall med hjälp av en fil från beräkningsprogrammet sparas mycket tid och arbete. Den som utformar skylten behöver då bara lägga till några få data själv och kan välja språk direkt i programmet istället för att behöva skriva allt för hand.Resultatet av detta examensarbete blev ett program som används av ABB för att göra skyltar till nästan alla mättransformatorer.

Hydrobiidae (Gastropoda, Neotaenioglossa, Rissooidea) da planície costeira do Rio Grande do Sul, Brasil

A família Hydrobiidae, que apresenta maior diversidade entre os moluscos límnicos e estuarinos, com mais de 300 gêneros e cerca de mil espécies Recentes, constitui-se em um importante componente biótico de águas continentais. A monofilia da família ainda é duvidosa, uma vez que a maioria das espécies é apenas conhecida pelos caracteres da concha, opérculo, pênis e rádula, insuficientes para traçar relações filogenéticas em Hydrobiidae. Apresentam alta diversidade específica e genérica, nos diferentes continentes, sendo a América do Sul uma exceção, com 120 espécies em sete gêneros recentes, enquanto que na América do Norte as mais de 200 espécies da família estão distribuídas em 40 gêneros, como registrado pela literatura. Estes caracóis acham-se distribuídos ao longo de toda Planície Costeira do Rio Grande do Sul, Brasil. A presente tese objetiva: identificar, definir e redefinir os hidrobiideos ocorrentes em ambientes límnicos e estuarinos da Planície Costeira do Rio Grande do Sul, a partir de coleções científicas e amostragens de material vivo. Examinou-se Hydrobiidae das coleções: Museu Museu de Ciências Naturais da Fundação Zoobotânica do Rio Grande do Sul (MCNZ); Departamento de Zoologia da Universidade Federal do Rio Grande do Sul (UFRGS); coleção particular de Rosane Lanzer (RL); The Academy of Natural Sciences of Philadelphia (ANSP); The Natural History Museum, Londres (BMNH). Realizou-se coleta no rio Hercílio em Santa Catarina, nas lagoas Itapeva, Tramandaí, Rondinha, Fortaleza e arroio do Carvão (bacia do rio Maquiné) no Rio Grande do Sul, utilizando peneira com malha de 1mm de abertura para a amostragem. Material coletado está depositado na coleção de moluscos da UFRGS. Obtiveram-se dados conquililógicos, conquiliometricos e morfoanatômicos in vivo - cabeça-pé, cavidade palial, sistemas reprodutores feminino e masculino e rádula. As ilustrações correspondem a desenhos da morfo-anatomia, e fotomicrografias da concha, opérculo, cabeça-pé e rádula. Foram inventariados 145 táxons do grupo da espécie de Hydrobiidae, descritos para a América do Sul, acrescidos de lista sinonímica e informações morfológicas de material-tipo. Registram-se os seguintes hidrobídeos para Planície Costeira do Rio Grande do Sul: Heleobia australis (Orbingy, 1835) (rio Tramandaí, lagunas Tramandaí e Armazém, lagoas Custódia e Paurá e laguna dos Patos); Heleobia bertoniana (Pilsbry, 1911) (lagoa Caieiras); Heleobia cuzcoensis (Pilsbry, 1911) ( lagoa Rondinha); Heleobia doellojuradoi (Parodiz, 1960) (lagoas Figueiras, Bojuru Velho e Mangueira); Heleobia parchappei (Orbigny, 1835) (lagoas Itapeva, Quadros, Ramalhete, Negra, Malvas, Marcelino, Quintão, Barro Velho, Moleques, Peixe, Jacaré, Mangueira e Laguna dos Patos); Heleobia xi sp. (lagoas Itapeva, Quadros, Malvas, Palmital, Pinguela, Lessa, Peixoto, Marcelino, laguna Tramandaí, lagoas Gentil, Manuel Nunes, Fortaleza, Rondinha, Cerquinha, Rincão das Éguas, Cipó, Porteira, Capão Alto, Quintão, Charqueadas, Barro Velho, São Simão, Veiana, laguna Mirim, lagoas Nicola e Jacaré); Potamolithus kusteri (Strobel, 1874) (arroio Carvão); Potamolithus philippianus Pilsbry, 1911 (lagoas Itapeva e Figueiras). Registra-se pela primeira vez para o Brasil, H. bertoniana, H. doelojuradoi e P. kusteri; para o Rio Grande do Sul, P. philippianus; e para a Planície Costeira, H. cuzcoensis. A partir de topótipos, é redescrito o táxon Potamolithus catharinae Pilsbry, 1911, assinalado na literatura para o litoral norte da Planície Costeira do Rio Grande do Sul, cuja ocorrência não é confirmada. Heleobia charruana (Orbigny, 1835), registrada na literatura para o litoral norte do RS, não tem sua ocorrência confirmada. Transfere-se o gênero monotípico Parodizia, arrolado entre os hidrobídeos, para Pyramidellidae (Gastropoda, Heterobranchia), a partir da morfologia das partes moles, desconhecidas até o presente. A morfologia do pênis de exemplares de Potamolithus kusteri (Strobel, 1874), do arroio Carvão, justifica sua remoção de Heleobia para Potamolithus. Heleobia australis nana (MARCUS & MARCUS, 1963) é considerada sinônimo de H. australis, por tratar-se de táxons morfoanatomicamente iguais. As distintas dimensões da concha (2,0 a 8,4 mm) de populações, ao longo da distribuição da espécie (Rio de Janeiro á Baía San Blás), decorrem de fatores ambientais, provavelmente relacionados com o grau de variação da salinidade.
