Phylogenetic analysis of Piscirickettsia salmonis by 16S, internal transcribed spacer (ITS) and 23S ribosomal DNA sequencing. (1/608)

Piscirickettsia salmonis, the etiologic agent of piscirickettsiosis, is a systemic disease of salmonid fish. Variations in virulence and mortality have been observed during epizootics at different geographical regions and in laboratory experiments with isolates from these different locations. This raises the possibility that biogeographical patterns of genetic variation might be a significant factor with this disease. To assess the genetic variability the 16S ribosomal DNA, the internal transcribed spacer (ITS) and the 23S ribosomal DNA of isolates from 3 different hosts and 3 geographic origins were amplified using the polymerase chain reaction (PCR). Results of this analysis confirm that P. salmonis is a member of the gamma subgroup of the Proteobacteria and show that the isolates form a tight monophyletic cluster with 16S rDNA similarities ranging from 99.7 to 98.5%. The ITS regions were 309 base pairs (bp), did not contain tRNA genes, and varied between isolates (95.2 to 99.7% similarity). Two-thirds of the 23S rRNA gene was sequenced from 5 of the isolates, yielding similarities ranging from 97.9 to 99.8%. Phylogenetic trees were constructed based on the 16S rDNA, ITS and 23S rDNA sequence data and compared. The trees were topologically similar, suggesting that the 3 types of molecules provided similar phylogenetic information. Five of the isolates are closely related (> 99.4% 16S rDNA similarity, 99.1% to 99.7% ITS and 99.3 to 99.8% 23S rDNA similarities). The sequence of one Chilean isolate, EM-90, was unique, with 16S rDNA similarities to the other isolates ranging from 98.5 to 98.9%, the ITS from 95.2 to 96.9% and the 23S rDNA from 97.6 to 98.5%.  (+info)

Transformation of sulfur compounds by an abundant lineage of marine bacteria in the alpha-subclass of the class Proteobacteria. (2/608)

Members of a group of marine bacteria that is numerically important in coastal seawater and sediments were characterized with respect to their ability to transform organic and inorganic sulfur compounds. Fifteen strains representing the Roseobacter group (a phylogenetic cluster of marine bacteria in the alpha-subclass of the class Proteobacteria) were isolated from seawater, primarily from the southeastern United States. Although more than one-half of the isolates were obtained without any selection for sulfur metabolism, all of the isolates were able to degrade the sulfur-containing osmolyte dimethyl sulfoniopropionate (DMSP) with production of dimethyl sulfide (DMS). Five isolates also degraded DMSP with production of methanethiol, indicating that both cleavage and demethylation pathways for DMSP occurred in the same organism, which is unusual. Five isolates were able to reduce dimethyl sulfoxide to DMS, and several isolates also degraded DMS and methanethiol. Sulfite oxygenase activity and methanesulfonic acid oxygenase activity were also present in some of the isolates. The ability to incorporate the reduced sulfur in DMSP and methanethiol into cellular material was studied with one of the isolates. A group-specific 16S rRNA probe indicated that the relative abundance of uncultured bacteria in the Roseobacter group increased in seawater enriched with DMSP or DMS. Because this group typically accounts for >10% of the 16S ribosomal DNA pool in coastal seawater and sediments of the southern United States, clues about its potential biogeochemical role are of particular interest. Studies of culturable representatives suggested that the group could mediate a number of steps in the cycling of both organic and inorganic forms of sulfur in marine environments.  (+info)

Purification and characterization of the soluble methane monooxygenase of the type II methanotrophic bacterium Methylocystis sp. strain WI 14. (3/608)

Methane monooxygenase (MMO) catalyzes the oxidation of methane to methanol as the first step of methane degradation. A soluble NAD(P)H-dependent methane monooxygenase (sMMO) from the type II methanotrophic bacterium WI 14 was purified to homogeneity. Sequencing of the 16S rDNA and comparison with that of other known methanotrophic bacteria confirmed that strain WI 14 is very close to the genus Methylocystis. The sMMO is expressed only during growth under copper limitation (<0.1 microM) and with ammonium or nitrate ions as the nitrogen source. The enzyme exhibits a low substrate specificity and is able to oxidize several alkanes and alkenes, cyclic hydrocarbons, aromatics, and halogenic aromatics. It has three components, hydroxylase, reductase and protein B, which is involved in enzyme regulation and increases sMMO activity about 10-fold. The relative molecular masses of the native components were estimated to be 229, 41, and 18 kDa, respectively. The hydroxylase contains three subunits with relative molecular masses of 57, 43, and 23 kDa, which are present in stoichiometric amounts, suggesting that the native protein has an alpha(2)beta(2)gamma(2) structure. We detected 3.6 mol of iron per mol of hydroxylase by atomic absorption spectrometry. sMMO is strongly inhibited by Hg(2+) ions (with a total loss of enzyme activity at 0.01 mM Hg(2+)) and Cu(2+), Zn(2+), and Ni(2+) ions (95, 80, and 40% loss of activity at 1 mM ions). The complete sMMO gene sequence has been determined. sMMO genes from strain WI 14 are clustered on the chromosome and show a high degree of homology (at both the nucleotide and amino acid levels) to the corresponding genes from Methylosinus trichosporium OB3b, Methylocystis sp. strain M, and Methylococcus capsulatus (Bath).  (+info)

Poly(aspartic acid) degradation by a Sphingomonas sp. isolated from freshwater. (4/608)

A poly(aspartic acid) degrading bacterium (strain KT-1 [JCM10459]) was isolated from river water and identified as a member of the genus Sphingomonas. The isolate degraded only poly(aspartic acid)s of low molecular masses (<5 kDa), while the cell extract hydrolyzed high-molecular-mass poly(aspartic acid)s of 5 to 150 kDa to yield aspartic acid monomer.  (+info)

Characterization of a separate small domain derived from the 5' end of 23S rRNA of an alpha-proteobacterium. (5/608)

We demonstrate the presence of a separate processed domain derived from the 5' end of 23S rRNA in ribosomes of Rhodopseudomonas palustris, a member of the alpha-++proteobacteria. Previous sequencing studies predicted intervening sequences (IVS) at homologous positions within the 23S rRNA genes of several alpha-proteobacteria, including R.palustris, and we find a processed 23S rRNA 5' domain in unfractionated RNA from several species. 5.8S rRNA from eukaryotic cytoplasmic large subunit ribosomes and the bacterial processed 23S rRNA 5' domain share homology, possess similar structures and are both derived by processing of large precursors. However, the internal transcribed spacer regions or IVSs separating them from the main large subunit rRNAs are evolutionarily unrelated. Consistent with the difference in sequence, we find that the site and mechanism of IVS processing also differs. Rhodopseudomonas palustris IVS-containing RNA precursors are cleaved in vitro by Escherichia coli RNase III or a similar activity present in R.palustris extracts at a processing site distinct from that found in eukaryotic systems and this results in only partial processing of the IVS. Surprisingly, in a reaction unlike characterized cases of eubacterial IVS processing, an RNA segment larger than the corresponding DNA insertion is removed which contains conserved sequences. These sequences, by analogy, serve to link the 23S rRNA 5' rRNA domains or 5.8S rRNAs to the main portion of other prokaryotic 23S rRNAs or to eukaryotic 28S rRNAs, respectively.  (+info)

Bartonella vinsonii subsp. berkhoffii and related members of the alpha subdivision of the Proteobacteria in dogs with cardiac arrhythmias, endocarditis, or myocarditis. (6/608)

Cardiac arrhythmias, endocarditis, or myocarditis was identified in 12 dogs, of which 11 were seroreactive to Bartonella vinsonii subspecies berkhoffii antigens. Historical abnormalities were highly variable but frequently included substantial weight loss, syncope, collapse, or sudden death. Fever was an infrequently detected abnormality. Cardiac disease was diagnosed following an illness of short duration in most dogs, but a protracted illness of at least 6 months' duration was reported for four dogs. Valvular endocarditis was diagnosed echocardiographically or histologically in eight dogs, two of which also had moderate to severe multifocal myocarditis. Four dogs lacking definitive evidence of endocarditis were included because of seroreactivity to B. vinsonii antigens and uncharacterized heart murmurs and/or arrhythmias. Alpha proteobacteria were not isolated from the blood by either conventional or lysis centrifugation blood culture techniques. Using PCR amplification and DNA sequencing of a portion of the 16S rRNA gene, B. vinsonii was identified in the blood or heart valves of three dogs. DNA sequence alignment of PCR amplicons derived from blood or tissue samples from seven dogs clustered among members of the alpha subdivision of the Proteobacteria and suggested the possibility of involvement of one or more alpha proteobacteria; however, because of the limited quantity of sequence, the genus could not be identified. Serologic or molecular evidence of coinfection with tick-transmitted pathogens, including Ehrlichia canis, Babesia canis, Babesia gibsonii, or spotted fever group rickettsiae, was obtained for seven dogs. We conclude that B. vinsonii subsp. berkhoffii and closely related species of alpha proteobacteria are an important, previously unrecognized cause of arrhythmias, endocarditis, myocarditis, syncope, and sudden death in dogs.  (+info)

Oxidation of methyl halides by the facultative methylotroph strain IMB-1. (7/608)

Washed cell suspensions of the facultative methylotroph strain IMB-1 grown on methyl bromide (MeBr) were able to consume methyl chloride (MeCl) and methyl iodide (MeI) as well as MeBr. Consumption of >100 microM MeBr by cells grown on glucose, acetate, or monomethylamine required induction. Induction was inhibited by chloramphenicol. However, cells had a constitutive ability to consume low concentrations (<20 nM) of MeBr. Glucose-grown cells were able to readily oxidize [(14)C]formaldehyde to (14)CO(2) but had only a small capacity for oxidation of [(14)C]methanol. Preincubation of cells with MeBr did not affect either activity, but MeBr-induced cells had a greater capacity for [(14)C]MeBr oxidation than did cells without preincubation. Consumption of MeBr was inhibited by MeI, and MeCl consumption was inhibited by MeBr. No inhibition of MeBr consumption occurred with methyl fluoride, propyl iodide, dibromomethane, dichloromethane, or difluoromethane, and in addition cells did not oxidize any of these compounds. Cells displayed Michaelis-Menten kinetics for the various methyl halides, with apparent K(s) values of 190, 280, and 6,100 nM for MeBr, MeI, and MeCl, respectively. These results suggest the presence of a single oxidation enzyme system specific for methyl halides (other than methyl fluoride) which runs through formaldehyde to CO(2). The ease of induction of methyl halide oxidation in strain IMB-1 should facilitate its mass culture for the purpose of reducing MeBr emissions to the atmosphere from fumigated soils.  (+info)

Characterization and identification of numerically abundant culturable bacteria from the anoxic bulk soil of rice paddy microcosms. (8/608)

Most-probable-number (liquid serial dilution culture) counts were obtained for polysaccharolytic and saccharolytic fermenting bacteria in the anoxic bulk soil of flooded microcosms containing rice plants. The highest viable counts (up to 2.5 x 10(8) cells per g [dry weight] of soil) were obtained by using xylan, pectin, or a mixture of seven mono- and disaccharides as the growth substrate. The total cell count for the soil, as determined by using 4', 6-diamidino-2-phenylindole staining, was 4.8 x 10(8) cells per g (dry weight) of soil. The nine strains isolated from the terminal positive tubes in counting experiments which yielded culturable populations that were equivalent to about 5% or more of the total microscopic count population belonged to the division Verrucomicrobia, the Cytophaga-Flavobacterium-Bacteroides division, clostridial cluster XIVa, clostridial cluster IX, Bacillus spp., and the class Actinobacteria. Isolates originating from the terminal positive tubes of liquid dilution series can be expected to be representatives of species whose populations in the soil are large. None of the isolates had 16S rRNA gene sequences identical to 16S rRNA gene sequences of previously described species for which data are available. Eight of the nine strains isolated fermented sugars to acetate and propionate (and some also fermented sugars to succinate). The closest relatives of these strains (except for the two strains of actinobacteria) were as-yet-uncultivated bacteria detected in the same soil sample by cloning PCR-amplified 16S rRNA genes (U. Hengstmann, K.-J. Chin, P. H. Janssen, and W. Liesack, Appl. Environ. Microbiol. 65:5050-5058, 1999). Twelve other isolates, which originated from most-probable-number counting series indicating that the culturable populations were smaller, were less closely related to cloned 16S rRNA genes.  (+info)

By the way, I have recently read that Pelagibacter, arguably the most abundant organism on this planet (or at least a strong contender for the title) is a close cousin of the mitochondrion ancestor -- they could even be treated as sister taxa, according to some analyses. Pelagibacter has the smallest genome of all free-living life forms, but it can make twenty amino acids and most of the common cofactors. One hypothesis about the evolution of alphaproteobacteria is that the common ancestor of Rickettsiales (including the proto-mitochondrion) was an endosymbiont (of the eocyte ancestor of Eukaryota?), and that Pelagibacter reverted to a free-swimming lifestyle after its genome had undergone slimming down in the intracellular environment, but before it lost any of its essential metabolic genes to the hosts nuclear genome. I suspect, however, that its incredibly vast population (measured in octillions, no less) may be a sufficient explanation of the extremely streamlined genome.. Delete ...
There is some disagreement on the phylogeny of the orders, especially for the location of the Pelagibacterales, but overall there is some consensus. This issue stems form the large difference in gene content (eg. genome streamlining in Pelagibacter ubique) and the large difference in GC-richness between members of several order.[2] Specifically,Pelagibacterales, Rickettsiales and Holosporales contains species with AT-rich genomes. It has been argued that it could be a case of convergent evolution that would result in an artefactual clustering.[6][7][8] However, several studies disagree,.[2][9][10][11] Furthermore, it has been found that the GC-content of ribosomal RNA, the traditional phylogenetic marker, little reflects the GC-content of the genome: for example, members of the Holosporales have a much higher ribosomal GC-content than members of the Pelagibacterales and Rickettsiales, which have similarly low genomic GC-content, because they are more closely related to species with high genomic ...
Alphaproteobacteria show a great versatility in adapting to a broad range of environments and lifestyles, with the association between bacteria and plants as one of the most intriguing, spanning from relatively unspecific nonsymbiotic association (as rhizospheric or endophytic strains) to the highly species-specific interaction of rhizobia. To shed some light on possible common genetic features in such a heterogeneous set of plant associations, the genomes of 92 Alphaproteobacteria strains were analyzed with a fuzzy orthologs-species detection approach. This showed that the different habitats and lifestyles of plant-associated bacteria (soil, plant colonizers, symbiont) are partially reflected by the trend to have larger genomes with respect to nonplant-associated species. A relatively large set of genes specific to symbiotic bacteria (73 orthologous groups) was found, with a remarkable presence of regulators, sugar transporters, metabolic enzymes, nodulation genes and several genes with unknown

Two non-motile, orange- or yellow-pigmented bacteria, designated strains KYW48T and KYW147T, were isolated from seawater collected from the South Sea, Republic of Korea. Cells of both strains were Gram-reaction-negative, aerobic and catalase- and oxidase-positive. The major fatty acids of strain KYW48T were C18 : 1ω7c (35.3 %), summed feature 3 (iso-C15 : 0 2-OH and/or C16 : 1ω7c) (22.7 %), C17 : 1ω6c (19.8 %), C14 : 0 2-OH (7.4 %) and C16 : 0 (5.9 %), and those of strain KYW147T were C18 : 1ω7c (36.0 %), summed feature 3 (18.3 %), C16 : 0 (14.7 %), 11-methyl C18 : 1ω7c (10.7 %), C16 : 0 2-OH (9.1 %) and C18 : 1ω9c (8.0 %). The predominant isoprenoid quinone of both strains was ubiquinone 10 (Q-10). The DNA G+C contents of strains KYW48T and KYW147T were 63.8 and 67.2 mol%, respectively. A phylogenetic tree based on 16S rRNA gene sequences showed that strains KYW48T and KYW147T were grouped with the members of the family Erythrobacteraceae and formed a distinct clade with the members of the genus
If you have ever been bitten by a tick, there is a significant chance that you now also have midi-chlorians! To be precise, a micro-organism called Midichloria mitochondrii* that belongs to the order of Rickettsiales. Evolutionary speaking, these Rickettsiales are closely related to organisms that once evolved into our mitochondria; in that sense Midichloria is very much connected to our force of life. Unfortunately, as far as is known, the real Midichloria does not incorporate super-human powers. Data about this micro-organism is scarce, but recent publications show that it deserves more attention (1-3).. Many hard ticks, such as Ixodes ricinus, are infected with Midichloria - it is present in all females and about half of all the male ticks. The endosymbiont is located inside the cells of the tick, and in particular in the mitochondria, which it slowly consumes. Incidentally, the tick itself does not seem to be affected. Midichloria is the first micro-organism that is known to be able to ...

Bacteria are mediators of biogeochemical cycles and are in this way vital for maintaining life on earth. Their distribution, abundance and functioning are driven by environmental heterogeneity and dynamic change in abiotic and biotic factors. Both, freshwater lakes and oceans play central roles in the global carbon cycle and bacteria in these systems perform many services for the ecosystems, such as the transfer of organic carbon from primary producers to higher trophic levels. With estimated relative abundances up to 50% of the total bacterioplankton, the Alphaproteobacteria lineage SAR11 is the most abundant group of aquatic bacteria. It is globally distributed and can be partitioned into multiple sub-clades, one of which is exclusive to freshwaters. Until recently, the distribution, abundance and ecological role of this freshwater SAR11 named LD12 was unknown. The aim of the thesis was to study the drivers and mechanisms that influence the dynamics of aquatic bacterial communities in general ...

Among communities of microorganisms, interspecies gene transfer is rife, but as a microbial community consumes local resources and develops in time and space, it is becoming increasingly apparent that the products of diverse metabolic activities can also be publicly shared. Otteson et al. set adrift a buoy with a robotic sampler off the coast of northern California to collect, every 4 hours over 2 days and about 50 km of distance, wild picoplankton for community RNA sequencing. Analyses of transcriptional dynamics revealed that the photosynthetic eukaryote Ostreococcus and the bacterium Synechococcus co-expressed large numbers of genes diurnally. The proteorhodopsin-expressing heterotroph Pelagibacter did not show diel gene expression but did show well-orchestrated regulatory patterns and a high degree of covariance between some major metabolic pathways, indicating immediate responses to changing growth conditions. Whether this apparent coordination stems from species-to-species communication ...

Multidrug-resistant (MDR) Gram-negative bacteria have emerged as a serious threat to human and animal health. Bdellovibrio spp. and Micavibrio spp. are Gram-negative bacteria that prey on other Gram-negative bacteria. In this study, the ability of Bdellovibrio bacteriovorus and Micavibrio aeruginosavorus to prey on MDR Gram-negative clinical strains was examined. Although the potential use of predatory bacteria to attack MDR pathogens has been suggested, the data supporting these claims is lacking. By conducting predation experiments we have established that predatory bacteria have the capacity to attack clinical strains of a variety of ß-lactamase-producing, MDR Gram-negative bacteria. Our observations indicate that predatory bacteria maintained their ability to prey on MDR bacteria regardless of their antimicrobial resistance, hence, might be used as therapeutic agents where other antimicrobial drugs fail.

Peptidoglycan contain peptide cross-links to link adjacent glycan strands. In Gram-negative bacteria, the vast majority of cross-links are typically made by DD-transpeptidation, with only a small percentage of cross-links made by LD-transpeptidation.. In contrast, the peptidoglycan profile of A. tumefaciens reveals that only about half the cross-links are made by DD-transpeptidation. The remaining half of the cross-links are made through LD-transpeptidation. This observation has led us to hypothesize the LD-transpeptidation may play an important role in the synthesis of peptidoglycan in A. tumefaciens. We have identified 4 putative LD-transpeptidases in the A. tumefaciens genome and are in the process of characterizing the role of these enzymes in peptidoglycan synthesis.. What is the big picture? Knowledge gained though these studies will be applied to enhance our understanding of the precisely targeted growth in other Alphaproteobacteria, including those that display remarkable morphologies. ...
This work presents the first screening aimed at detecting DNA from tick-associated Midichloriaceae bacteria in mammalians. A total of 156 blood samples derived from horses, cattle, sheep and dogs at risk of tick bite were analyzed by PCR, using a previously described PCR protocol targeted on the 16S rDNA gene of M. mitochondrii and related bacteria [9]. Blood samples from 30 cattle and 20 dogs that are regarded as having no or limited risk of tick bite were also included. Details on the different groups of animals examined are listed in Table 1.. The quality of the DNAs extracted was checked by PCR using universal mammalian primers targeted on the mitochondrial 12S rRNA gene that led to positive amplification from all samples. Midichloria-targeted primers led to positive amplification from 26 of the animals at risk of tick bite, and from none of the control animals (Table 1). The animal species that presented the higher prevalence of positive animals was the dog, where 20 out of 86 animals were ...

We examined the distribution of NAGS and NAGK across the three domains of life. Although NAGK is found in archaea, eubacteria and eukaryotes, such as plants, algae and fungi, initially, we were only able to find sequences similar to either E. coli or mammalian NAGS in beta-proteobacteria, gamma-proteobacteria and three species of alpha-proteobacteria [48-50]. The three alpha-proteobacteria, M. maris, O. alexandrii and P. bermudensis, also appear to harbor acetylornithine transcarbamylase (argF) genes suggesting that their arginine biosynthesis pathway is similar to the one in X. campestris [7]. Identification of the alpha-proteobacterial NAGS genes that are closely related to the corresponding vertebrate, fungal and algal genes and to fungal NAGK is intriguing because mitochondria are thought to have arisen by endosymbiosis between proto-eukaryotic cell and an alpha-proteobacteria. Current thought suggests that the alpha-proteobacteria of the order Rickettsiales are the extant relatives of the ...
The Rickettsiales, also called rickettsias, are an order of small Alphaproteobacteria that are endosymbionts of eukaryotic cells. Some are notable pathogens, including Rickettsia, which causes a variety of diseases in humans, and Ehrlichia, which causes diseases in livestock. Another genus of well-known Rickettsiales are the Wolbachia, which infect approximately two-thirds of all arthropods and nearly all filarial nematodes . Genetic studies support the endosymbiotic theory according to which mitochondria and related organelles developed from members of this group. The Rickettsiales are difficult to cultivate, because they rely on eukaryotic host cells for their survival. The Rickettsiales further consist of three known families, the Rickettsiaceae, the Midichloriaceae and the Anaplasmataceae. Most studies also support the inclusion of the Holosporaceae, but one study has challenged this view . Here, the Holosporaceae are the sole representatives of its own order, the Holosporales and as such ...

One contentious method by which bacteria deal with a maladapted situation is what has been coined adaptive, directed or stress induced-mutation. This involves mutants that compensate for some form of sub-lethal stress appearing in large numbers from an apparently non-dividing cell population after a protracted period of time. In Mesorhizobium loti this was first observed in the non-symbiotic strains CJ1 and N18. The stress-induced mutation involved the activation of a cryptic chromosomal dctABD locus which allowed these strains to utilize succinate as a sole carbon source (Dct+). In the current study the symbiotic strain R7A, which containsan integrative and conjugative element ICEMlSymR7A, was also shown to produce Dct+ mutants when under stress, when its active dct locus on ICEMlSymR7A was deleted. However a derivative of R7A cured of ICEMlSymR7A (strain R7ANS), did not form mutant colonies strongly suggesting that the causative locus was located on ICEMlSymR7A. In this work, the ...
A bacterial strain, B5-2(T), was isolated from an ice core drilled from Muztagh Glacier, China. Strain B5-2(T) was a Gram-stainnegative, short rod-shaped, motile by polar flagella, aerobic bacterium. The major fatty acids of strain B5-2(T) were summed feature 8 (C-18 : 1 omega 7c and/ or C-18 : 1 omega 6c) and iso-C-13 : 0. The G+C content of the DNA from strain B5-2(T) was 69.3 mol%. The predominant isoprenoid quinone of strain B5-2(T) was Q-10. The major polar lipids were phosphatidylglycerol, phosphatidylethanolamine, phosphatidylmonomethylethanolamine, phosphatidyldimethylethanolamine, phosphatidylcholine, an unidentified phospholipid and sulfoquinovosyldiacylglycerol. Comparative 16S rRNA gene sequence analysis revealed that the novel strain B5-2(T) shared highest similarity (96.7 %) with Aureimonas altamirensis S21B(T). On the basis of the results of this polyphasic study, strain B5-2(T) represents a novel species of the genus Aureimonas, for which the name Aureimonas glaciei sp. nov. is ...

Carlson is used to represent some of the harshest themes in the novella; hes bitter and nasty and has very little respect for emotional sentiment. As a result, Carlson represents the classic, stereotypical ranch worker and the harsh realities of migrant life. Using his voice to end the novella is significant because it epitomises all of the absurdities of the ranch way of life; at the end of the novel, George is left to face all of the same horrible realities as the rest of the workers, he has no companion and his dream is now out of reach. Having a character who represents all of those negative qualities of ranch life end the novel highlights the idea that George was always doomed to face those negativities. The rhetorical question is also significant because its ironic and encourages the reader to continue questioning the book even after its end ...

Yorba Linda, Ca (PRWEB) May 04, 2017 -- Crohns disease (CD) results from a complex interplay between host genetic factors and endogenous microbial
The question refers to the so-called neptunium series, which can be observed as a whole only if artificial radioisotopes are producted. In fact the members of the series are concentrated in a sample of the longest-lived member, from which they derive, in concentrations proportional to the activity of each member. So, if the longest-lived member (in this case 237NP) has an half-life considerably inferior to the age of the Earth, we can assume that its concentration on the Earth has become too low to be traceable (almost exhausted). The exhaustion of the longest-lived member leads necessarily to the exhaustion of the whole series, which quite soon becomes transformed in the last, stable, member of te series. So, if we want to observe the series again, we are obliged to obtain the longest-lived member, the parent of the other members, following an artificial process, i. e. performing a nuclear reaction ...

The genetic and phylogenetic relationships for strains of Mesorhizobium tianshanense and its relatives were compared by an analysis of the results of sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) of whole-cell proteins, DNA-DNA hybridization, and full 16S rRNA gene sequencing. The strains of M. tianshanense formed a cluster which was distinct from those of other rhizobium species in the clustering analysis of SDS-PAGE. DNA-DNA relatedness between A-1BS (type strain of M. tianshanense) and the type or reference strains for Mesorhizobium loti, M. huakuii, M. ciceri, M. mediterraneum, and cluster U, an unnamed rhizobial group, ranged from 4.4 to 43.8%. The phylogenetic analysis based on the 16S rRNA gene sequences showed that M. tianshanense was closely related to the Mesorhizobium phylogenetic branch and could be distinguished from the other four species in this branch. These results further confirmed that these bacteria constitute a distinct rhizobial species.
Mesorhizobium loti mutant 2213.1 derived from the wild-type strain NZP2213 by Tn5 mutagenesis showed impaired effectiveness of symbiosis with the host plant Lotus corniculatus (Turska-Szewczuk et al., 2007 Microbiol Res, in press). The inability of lipopolysaccharide (LPS) isolated from the mutant 2213.1 strain or de-O-acetylated LPS of the parental cells to inactivate phage A1 particles implicated alterations in the LPS structure. The O-specific polysaccharide of the mutant was studied by chemical analyses along with 1H and 13C NMR spectroscopy, which clearly confirmed alterations in the O-chain structure. 2D NMR data showed that the mutant O-polysaccharide consists of a tetrasaccharide repeating unit containing non-substituted as well as O-acetylated or O-methylated 6-deoxytalopyranose residues. Additionally, an immunogold assay revealed a reduced number of gold particles on the mutant bacteroid cell surface, which could result from both a diminished amount of an O-antigenic determinant in ...
This paper describes improvement and comparison of analytical methods for simultaneous determination of trace-level plutonium and neptunium in urine samples by inductively coupled plasma mass spectrometry (ICP-MS). Four sample pre-concentration techniques, including calcium phosphate, iron hydroxide and manganese dioxide co-precipitation and evaporation were compared and the applicability of different techniques was discussed in order to evaluate and establish the optimal method for in vivo radioassay program. The analytical results indicate that the various sample pre-concentration approaches afford dissimilar method performances and care should be taken for specific experimental parameters for improving chemical yields. The best analytical performances in terms of turnaround time (6 h) and chemical yields for plutonium (88.7 +/- 11.6%) and neptunium (94.2 +/- 2.0%) were achieved by manganese dioxide co-precipitation. The need of drying ashing (,= 7 h) for calcium phosphate co-precipitation and ...

For production of proteins that are encoded by the mitochondrial genome, mitochondria rely on their own mitochondrial translation system, with the mitoribosome as its central component. Using extensive homology searches, we have reconstructed the evolutionary history of the mitoribosomal proteome that is encoded by a diverse subset of eukaryotic genomes, revealing an ancestral ribosome of alpha-proteobacterial descent that more than doubled its protein content in most eukaryotic lineages. We observe large variations in the protein content of mitoribosomes between different eukaryotes, with mammalian mitoribosomes sharing only 74 and 43% of its proteins with yeast and Leishmania mitoribosomes, respectively. We detected many previously unidentified mitochondrial ribosomal proteins (MRPs) and found that several have increased in size compared to their bacterial ancestral counterparts by addition of functional domains. Several new MRPs have originated via duplication of existing MRPs as well as by ...

In the halcyon days of professional mimics, shortly after theyd outpaced their predecessors, the vernacular storytellers, who had, a decade earlier, wrested the comedic throne from the one-liner royalty, it would have been difficult to name a town of ten thousand souls that didnt possess some venue where performed those artists who made their fame and fortune with stunning mimicry of the periods political leaders and actors, athletes and musicians, scholars, and men of science. And at every performance inside those theaters, whether located in the Badger or Beaver State, all seats were filled, as were the aisles and exits, prompting accounts of fire marshals arriving with the intent of stopping the show, only to get so caught up in their own laughter and enjoyment that they would forget their professional function as disperser of those bunched so close together as to create a hazard. Even the streets and sidewalks outside the theaters: they would be massed by citizens whod shown up too late ...

In argillaceous rocks, which are considered as a potential host rock for nuclear waste repositories, sorption and diffusion processes govern the migration behaviour of actinides like neptunium. For the safety analysis of such a repository, a molecular-level understanding of the transport and retardation phenomena of radioactive contaminants in the host rock is mandatory. The speciation of Np during sorption and diffusion in Opalinus Clay was studied at near neutral pH using a combination of spatially resolved synchrotron radiation techniques. During the sorption and diffusion experiments, the interaction of 8 μM Np(V) solutions with the clay lead to the formation of spots at the clay-water interface with increased Np concentrations as determined by μ-XRF. Several of these spots are correlated with areas of increased Fe concentration. Np L3-edge μ-XANES spectra revealed that up to 85% of the initial Np(V) was reduced to Np(IV). Pyrite could be identified by μ-XRD as a redox-active mineral ...

This is anthropological science fiction at its best, with only Ursula K. Le Guin rivaling Arnason in cultural insight and in the sophistication, complexity, and evocativeness of her worldbuilding. The hwarhath serve as a distorted mirror in which we can clearly see our own follies, foibles, peculiarities, and the inequalities of our society; the hwarhath, meanwhile, see humans as a distorted mirror in which they can see the peculiarities and inequalities of their own society. Arnason does her best work here at novella length, and I consider "The Potter of Bones" and "Dapple" to be among the very best novellas of their respective years, and as having an honorable place amongst the best SF novellas ever written. "The Hound of Merlin", "The Actors", "The Lovers", "The Garden", and "Holmes Sherlock" are also very strong; in fact, theres really nothing here that isnt worth reading.

Ticks are the second most important vector of pathogens to humans after mosquitoes and the chief cause of vector-borne diseases in domestic animals and wildlife [1-3]. Ticks also vector the greatest diversity of pathogenic microorganisms of any haematophagous arthropod, including members of the bacterial genera Anaplasma [4], Bartonella [5], Borrelia [6], Ehrlichia [7], Francisella [8], Rickettsia [9], and "Candidatus Neoehrlichia" [10]. Furthermore, bacterial co-infections in ticks are common and provide diagnostic and therapeutic challenges for medical and veterinary practitioners [11-13]. In Europe, North America, and Australia the incidence of tick-borne diseases is rising due to a combination of factors including perturbation in climate, increasing populations and movement of humans and domestic animals, and increased human encroachment into tick habitats [14].. In Australia there is a long-standing controversy concerning the presence of Lyme disease and its aetiological agents, Borrelia ...
A novel bacterium, designated R14M6T, was isolated from deep-sea sediment collected from the Ross Sea, Antarctica. Cells are Gram-stain-negative, aerobic, pale yellow, short-rod-shaped, polar-flagellated and aggregate-forming. Growth occurs at 4-36 °C, pH 6.0-8.3, and in 1-15 % (w/v) NaCl. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain R14M6T clustered together with Aurantimonas endophytica EGI6500337T and fell within the genus Aurantimonas . The 16S rRNA gene sequence of strain R14M6T shared similarity with A. endophytica EGI6500337T (99.15 %), A. manganoxydans DSM 21871T (97.73 %), A. coralicida DSM 14790T (97.58 %) and A. litoralis KCTC 12094 (97.51 %). The DNA-DNA relatedness values between strain R14M6T and A. endophytica EGI6500337T, A. coralicida DSM 14790T, A. manganoxydans DSM 21871T and A. litoralis KCTC 12094 were 36.9±4.5, 27.6±2.8, 29.6±1.2 and 25.2±2.4 % respectively.

The genus Brucella contains highly infectious species that are classified as biological threat agents. The timely detection and identification of the microorganism involved is essential for an effective response not only to biological warfare attacks but also to natural outbreaks. Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF-MS) is a rapid method for the analysis of biological samples. The advantages of this method, compared to conventional techniques, are rapidity, cost-effectiveness, accuracy and suitability for the high-throughput identification of bacteria. Discrepancies between taxonomy and genetic relatedness on the species and biovar level complicate the development of detection and identification assays. In this study, the accurate identification of Brucella species using MALDI-TOF-MS was achieved by constructing a Brucella reference library based on multilocus variable-number tandem repeat analysis (MLVA) data. By comparing MS-spectra from Brucella
Corresponding to previous reports (Babos, 1964), each leg terminated with an ambulacrum (pretarsus), which was composed of an elongated apotele bearing long, paired, rod-shaped, curved claws (Figs 2E-G and 3A,E).. They appeared lunate and transparent, having an average thickness of 15.1±1.31 µm (n=5) and a length of 135.2±17.58 µm (n=5). A thin outer cuticular layer surrounded the claw interior, which was completely filled with an amorphous material (see below).. They tapered into a mean claw tip diameter of 1.2±0.36 µm (n=10). The claw base was slightly broadened, reaching about 20.1±1.62 µm in width (n=5).. The mean diameter of a circle fitting the claw curvature measured 54.7±8.08 µm (n=10). Between the claws, a foldable pad arose (Figs 2E-G and 3A-D). The fluorescence microscopy images (Fig. 2F,G) revealed the presence of resilin, an elastic protein, in the materials of pads, claws and membranous areas surrounding the tarsal-pretarsal articulation.. The pad was composed of three ...
Wolbachia are maternally inherited, intracellular, alpha proteobacteria that infect a wide range of arthropods. They cause three kinds of reproductive alterations in their hosts: cytoplasmic incompatibility, parthenogenesis and feminization. There have been many studies of the distribution of Wolbachia in arthropods, but very few crustacean species are known to be infected. We investigated the prevalence of Wolbachia in 85 species from five crustacean orders. Twenty-two isopod species were found to carry these bacteria. The bacteria were found mainly in terrestrial species suggesting that Wolbachia came from a continental environment. The evolutionary relationships between these Wolbachia strains were determined by sequencing bacterial genes and by interspecific transfers. All the bacteria associated with isopods belonged to the wolbachiae B group, based on 16S rDNA sequence data. All the terrestrial isopod symbionts in this group except one formed an independent clade. The results of ...

  • To shed some light on possible common genetic features in such a heterogeneous set of plant associations, the genomes of 92 Alphaproteobacteria strains were analyzed with a fuzzy orthologs-species detection approach. (mdpi.com)
  • Alphaproteobacteria show a great versatility in adapting to a broad range of environments and lifestyles, with the association between bacteria and plants as one of the most intriguing, spanning from relatively unspecific nonsymbiotic association (as rhizospheric or endophytic strains) to the highly species-specific interaction of rhizobia.
