Gramella portivictoriae sp nov, a novel member of the family Flavobacteriaceae isolated from marine sediment (vol 55, pg 2497, 2005)

A yellow-pigmented, Gram-negative, slowly gliding, rod-shaped, strictly aerobic bacterium (UST040801-001T) was isolated from marine sediment. The DNA G+C content was 39?9 mol%. The predominant fatty acids were a15 : 0, i15 : 0, i15 : 0 3-OH, i17 : 1v9c, i17 : 0 3-OH and summed feature 3, comprising i15 : 0 2-OH and/or 16 : 1v7c (altogether representing 76?2% of the total). MK-6 was the only respiratory quinone. Flexirubin-type pigments were not produced. Phylogenetic analysis based on 16S rRNA gene sequences indicated that Gramella echinicola KMM 6050T (the only species in the genus) was the closest relative of UST040801-001T, sharing 98?0% sequence similarity. The DNA–DNA relatedness between UST040801-001T and Gramella echinicola KMM 6050T was 13 %. Strain UST040801-001T can be distinguished from G. echinicola by means of 11 phenotypic traits. The results of molecular and phenotypic analyses suggested that UST040801-001T represents a novel species of Gramella. The name Gramella portivictoriae sp. nov. is proposed for this bacterium, with UST040801-001T (=NRRL 41137T=JCM 13192T) as the type strain

Параметры периферической крови как маркеры неспецифического адаптационного ответа при острых инфекционных заболеваниях с синдромом тонзиллита

Evaluation of nonspecific adaptive response of the body in children with acute infectious diseases associated with tonsillitis syndrome was the aim of this research. This prospective study included clinical, anamnestic and laboratory examination of children with acute infectious diseases with tonsillitis syndrome. A systemic multiple factor analysis was conducted (significance level р<0.05). The evaluation of peripheral blood parameters (specific gravity of lymphocytes and indices of reactive protective potential (RPP) - specific immune lymphocytic-monocytic parameter (SILMP) and coefficient of phagocytic defense (CPD)) gives the possibility to determine the condition of nonspecific adaptation in children with acute infectious diseases associated with tonsillitis syndrome. Children with tonsillitis syndrome show significant increase of integral RPP parameters, i.e. decrease of RPP, which is more pronounced on discharge (on admission - in 57% of children, on discharge - in 87%). The most unfavourable initial nonspecific adaptative body response (NABR) (according to the percentage of lymphocytes) is the reaction of increased activation, as it is associated with the transition to the overactivation by the time of discharge (37% of children). Systemic multiple factor analysis determined which peripheral blood parameters have more influence on children’s adaptation during the course of infectious disease: RPP indices showed high influence coefficients in all diseases (CPD was the highest in bacterial infection - Рi 198.3; SILMP was the highest in viral infection - Рi 147.81; in mixed infection CPD and SILMP were roughly the same - Рi – 107.25 and Рi - 78.11, respectively), which proves the feasibility of RPP evaluation for prognostic purposes in the treatment of this category of patients.Целью настоящего исследования явилась оценка неспецифической адаптационной реакции организма у детей с острыми инфекционными заболеваниями, ассоциированными с синдромом тонзиллита. Данное проспективное исследование включало клинико-анамнестическое и лабораторное обследование детей с острыми инфекционными заболеваниями с синдромом тонзиллита. Проведен системный многофакторный анализ (уровень значимости р<0,05). Оценка показателей периферической крови (удельного веса лимфоцитов и показателей реактивно-протективный потенциал (РПП) - специфического иммунного лимфоцитарно-моноцитарного параметра (ИЛМП) и коэффициента фагоцитарной защиты (КФЗ) дает возможность определить состояние неспецифической адаптации у детей с острыми инфекционными заболеваниями, ассоциированными с синдромом тонзиллита. У детей с синдромом тонзиллита отмечается достоверное повышение интегральных показателей РПП, т. е. снижение РПП, которое более выражено при выписке (при поступлении - у 57% детей, при выписке - у 87%). Наиболее неблагоприятной исходной неспецифической адаптационной реакцией организма (по проценту лимфоцитов) является реакция повышенной активации, так как она связана с переходом к гиперактивации к моменту выписки (37% детей). Системный многофакторный анализ определил, какие показатели периферической крови оказывают большее влияние на адаптацию детей в течение инфекционного заболевания: показатели РПП показали высокие коэффициенты влияния при всех заболеваниях, что доказывает целесообразность оценки РПП в прогностических целях при лечении данной категории больных

Description of Fabibacter halotolerans gen. nov., and reclassification of [Marinicola] seohaensis as Roseivirga seahaensis comb. nov.

Bacterial strains UST030701-097T and UST030701-084T were isolated from a marine sponge in the Bahamas. Both strains were pink-pigmented, Gram-negative, strictly aerobic and chemo-organotrophic. Cells of strain UST030701-097T were short, curved rods with fast-gliding motility, whereas those of strain UST030701-084T were straight rods with a less rapid gliding motion. The two strains had MK-7 as the major respiratory quinone and did not produce flexirubin-type pigments. The DNA G+C contents of strains UST030701-097T and UST030701-084T were 42.5 and 43.7 mol%, respectively. Phylogenetic analysis based on 16S rRNA gene sequences indicated that the two strains belonged to the family 'Flexibacteraceae' of the phylum Bacteroidetes. 16S rRNA gene sequence similarity between strains UST030701-097T and UST030701-084T was 95.0 %; their closest relative was [Marinicola] seohaensis, with 93.3 % and 96.0 % sequence similarity, respectively. Phylogenetic tree topology indicated that the two strains belonged to the same lineage, but were on separate branches. Whilst strain UST030701-084T and [Marinicola] seohaensis were found on one branch, strain UST030701-097T was in another branch that had no species with validly published names. Based on the polyphasic taxonomic data obtained in the present study, we propose that strain UST030701-097T represents a novel genus and that strain UST030701-084T represents a novel species in the phylum Bacteroidetes. The genus Fabibacter gen. nov. is proposed, with strain UST030701-097T (=NRRL B-41220T=JCM 13334T) as the type strain of the type species, Fabibacter halotolerans sp. nov. Strain UST030701-084T (=NRRL B-41219T=JCM 13337T) is proposed as the type strain of Roseivirga spongicola sp. nov. In an earlier study, it was suggested that the genus Marinicola is a later heterotypic synonym of the genus Roseivirga. However, a formal proposal to reclassify [Marinicola] seohaensis, the only member of the genus Marinicola, has not yet been made. The results of phylogenetic analyses in this study support the reclassification of [Marinicola] seohaensis as Roseivirga seohaensis comb. nov

Stenothermobacter spongiae gen. nov., sp. nov., a novel member of the family Flavobacteriaceae isolated from a marine sponge in the Bahamas, and emended description of Nonlabens tegetincola

A bacterial strain, UST030701-156T, was isolated from a marine sponge in the Bahamas. Strain UST030701-156T was orange-pigmented, Gram-negative, rod-shaped with tapered ends, slowly motile by gliding and strictly aerobic. The predominant fatty acids were a15 : 0, i15 : 0, i15 : 0 3-OH, i17 : 0 3-OH, i17 : 1ω9c and summed feature 3, comprising i15 : 0 2-OH and/or 16 : 1ω7c. MK-6 was the only respiratory quinone. Flexirubin-type pigments were not produced. Phylogenetic analysis based on 16S rRNA gene sequences placed UST030701-156T within a distinct lineage in the family Flavobacteriaceae, with 93·3 % sequence similarity to the nearest neighbour, Nonlabens tegetincola. The DNA G+C content of UST030701-156T was 41·0 mol% and was much higher than that of N. tegetincola (33·6 mol%). Strain UST030701-156T can be distinguished from other members of the Flavobacteriaceae by means of a number of chemotaxonomic and phenotypic characteristics. It is proposed, therefore, that UST030701-156T represents a novel taxon designated Stenothermobacter spongiae gen. nov., sp. nov. The type strain is UST030701-156T (=NRRL B-41138T=JCM 13191T). Carbon-source utilization by N. tegetincola was re-examined and an emended description is therefore included
