A genus of gram-negative, curved and spiral-shaped bacteria found in stagnant, freshwater environments. These organisms are motile by bipolar tufts of flagella having a long wavelength and about one helical turn. Some species of Spirillum cause a form of RAT-BITE FEVER.
A whiplike motility appendage present on the surface cells. Prokaryote flagella are composed of a protein called FLAGELLIN. Bacteria can have a single flagellum, a tuft at one pole, or multiple flagella covering the entire surface. In eukaryotes, flagella are threadlike protoplasmic extensions used to propel flagellates and sperm. Flagella have the same basic structure as CILIA but are longer in proportion to the cell bearing them and present in much smaller numbers. (From King & Stansfield, A Dictionary of Genetics, 4th ed)
The study of microorganisms such as fungi, bacteria, algae, archaea, and viruses.
One of the three domains of life (the others being Eukarya and ARCHAEA), also called Eubacteria. They are unicellular prokaryotic microorganisms which generally possess rigid cell walls, multiply by cell division, and exhibit three principal forms: round or coccal, rodlike or bacillary, and spiral or spirochetal. Bacteria can be classified by their response to OXYGEN: aerobic, anaerobic, or facultatively anaerobic; by the mode by which they obtain their energy: chemotrophy (via chemical reaction) or PHOTOTROPHY (via light reaction); for chemotrophs by their source of chemical energy: CHEMOLITHOTROPHY (from inorganic compounds) or chemoorganotrophy (from organic compounds); and by their source for CARBON; NITROGEN; etc.; HETEROTROPHY (from organic sources) or AUTOTROPHY (from CARBON DIOXIDE). They can also be classified by whether or not they stain (based on the structure of their CELL WALLS) with CRYSTAL VIOLET dye: gram-negative or gram-positive.
The organ of sight constituting a pair of globular organs made up of a three-layered roughly spherical structure specialized for receiving and responding to light.
A kingdom of eukaryotic, heterotrophic organisms that live parasitically as saprobes, including MUSHROOMS; YEASTS; smuts, molds, etc. They reproduce either sexually or asexually, and have life cycles that range from simple to complex. Filamentous fungi, commonly known as molds, refer to those that grow as multicellular colonies.
Common name for one of five species of small PARROTS, containing long tails.
Techniques used in microbiology.

Spirillum swimming: theory and observations of propulsion by the flagellar bundle. (1/76)

The hydrodynamics and energetics of helical swimming by the bacterium Spirillum sp. is analysed using observations from medium speed cine photomicrography and theory. The photographic records show that the swimming organism's flagellar bundles beat in a helical fashion just as other bacterial flagella do. The data are analysed according to the rotational resistive theory of Chwang & Wu (1971) in a simple-to-use parametric form with the viscous coefficients Cs and Cn calculated according to the method of Lighthill (1975). Results of the analysis show that Spirillum dissipated biochemical energy in performing work against fluid resistance to motion at an average rate of about 6 X 10(-8) dyne cm s-1 with some 62-72% of the power dissipation due to the non-contractile body. These relationships yield a relatively low hydromechanical efficiency which is reflected in swimming speeds much smaller than a representative eukaryote. In addition the Cn/Cs ratio for the body is shown to lie in the range 0-86-1-51 and that for the flagellar bundle in the range 1-46-1-63. The implications of the power calculations for the Berg & Anderson (1973) rotating shaft model are discussed and it is shown that a rotational resistive theory analysis predicts a 5-cross bridge M ring for each flagellum of Spirillum.  (+info)

Carbon and ammonia metabolism of Spirillum lipoferum. (2/76)

Intact cells and extracts from Spirillum lipoferum rapidly oxidized malate, succinate, lactate, and pyruvate. Glucose, galactose, fructose, acetate, and citrate did not increase the rate of O2 uptake by cells above the endogenous rate. Cells grown on NH+/4 oxidized the various substrates at about the same rate as did cells grown on N2. Added oxidized nicotinamide adenine dinucleotide generally enhanced O2 uptake by extracts supplied organic acids, whereas oxidized nicotinamide adenine dinucleotide phosphate had little effect. Nitrogenase synthesis repressed by growth of cells in the presence of NH+/4 was derepressed by methionine sulfoximine or methionine sulfone. The total glutamine synthetase activity from N2-grown cells was about eight times that from NH+/4-grown S. lipoferum; the response of glutamate dehydrogenase was the opposite. The total glutamate synthetase activity from N2-grown S. lipoferum was 1.4 to 2.6 times that from NH+/4-grown cells. The levels of poly-beta-hydroxybutyrate and beta-hydroxybutyrate dehydrogenase were elevated in cells grown on N2 as compared with those grown on NH+/4. Cell-free extracts capable of reducing C2H2 have been prepared; both Mg2+ and Mn2+ are required for good activity.  (+info)

Titanospirillum velox: a huge, speedy, sulfur-storing spirillum from Ebro Delta microbial mats. (3/76)

A long (20-30 micrometer), wide (3-5 micrometer) microbial-mat bacterium from the Ebro Delta (Tarragona, Spain) was grown in mixed culture and videographed live. Intracellular elemental sulfur globules and unique cell termini were observed in scanning-electron-microprobe and transmission-electron micrographs. A polar organelle underlies bundles of greater than 60 flagella at each indented terminus. These Gram-negative bacteria bend, flex, and swim in a spiral fashion; they translate at speeds greater than 10 body lengths per second. The large size of the spirillum permits direct observation of cell motility in single individual bacteria. After desiccation (i.e., absence of standing water for at least 24 h), large populations developed in mat samples remoistened with sea water. Ultrastructural observations reveal abundant large sulfur globules irregularly distributed in the cytoplasm. A multilayered cell wall, pliable and elastic yet rigid, distends around the sulfur globules. Details of the wall, multiflagellated termini, and large cytoplasmic sulfur globules indicate that these fast-moving spirilla are distinctive enough to warrant a genus and species designation: Titanospirillum velox genus nov., sp. nov. The same collection techniques at a similar habitat in the United States (Plum Island, northeast Essex County, Massachusetts) also yielded large populations of the bacterium among purple phototrophic and other inhabitants of sulfurous microbial-mat muds. The months-long survival of T. velox from Spain and from the United States in closed jars filled with mud taken from both localities leads us to infer that this large spirillum has a cosmopolitan distribution.  (+info)

Analysis of the cell wall and lipopolysaccharide of Spirillum serpens. (4/76)

Isolated walls of Spirillum serpens VHA contained lipid, lipopolysaccharide, and protein in amounts similar to those of other gram-negative organisms. The loosely bound lipids consisted mainly of phosphatidylethanolamine, lyso-phosphatidylethanolamine, phosphatidylglycerol, and diphosphatidylglycerol. Lipopolysaccharide was tightly bound to the wall and could only be removed in a substantial amount after digestion of the wall with Pronase. The lipopolysaccharide contained L-glycero-D-mannoheptose, rhamnose, glucosamine, ethanolamine, and phosphate in common with many of the lipopolysaccharides isolated from the Enterobacteriaceae. However, 2-keto-3-deoxyoctonic acid was not detected. Several unidentified sugars were present. The fatty acid composition resembled that found in lipopolysaccharides isolated from various pseudomonads. Two major regions were identified in the polysaccharide moiety, one apparently corresponding to the core polysaccharide and the other corresponding to the side-chain polysaccharide as in enterobacterial and pseudomonad lipopolysaccharides. The side chains were obtained as low-molecular-weight material and their structure was partially elucidated by the isolation and partial characterization of N-acetylglucosaminyl-(1 leads to 4)-rhamnose.  (+info)

Surface arrays on the cell wall of Spirillum metamorphum. (5/76)

A complex and easily disrupted arrangement of macromolecules was present on the outer (lipopolysaccharide) membrane of the cell wall of Spirillum metamorphum. Separation of the arrays from the cell and spontaneous reassembly into regularly structured complexes usually occurred during preparation for electron microscopy. Freeze etchings, thin sections, and optical diffraction analysis of negatively stained fragments indicated that they consisted of two sets of a thin layer which was studied with 3-nm particles arranged in a loose (OL). The OSL consisted of a hexagonal arrangement of 8-nm disks and the OL of a thin layer which was studied with 3-nm particles arranged in a loose rectangular manner. The OSL of reassembled fragments displayed numerous broken delta-linkers between units and a center-to-center spacing of half the expected distance, which suggests that an interdigitation of two OSL arrays had occurred. The observations combined with freeze etchings and thin sections of whole cells suggested a possible reassembly mechanism. The normal surface arrangement of these layers on cells was thought to consist of the OL overlying one set of OSL which was loosely adherent to a thin amorphous backing layer.  (+info)

Substructure and in vitro assembly of the outer, structured layer of Spirillum serpens. (6/76)

Electron micrographs of disintegrating units of the outer, structured (HP) layer of Spirillum serpens and of the isolated protein obtained from the HP layer revealed V- and Y-shaped and linear profiles. Interpretation of these forms, influenced by the seemingly trimeric form of the isolated protein and by biochemical data, suggested that the protein subunits were identical and Y shaped. A model is proposed for the assembly of the Y-shaped subunits to form a hexagon composed of two triads (three Y-shaped subunits each). The isolated protein adsorbed to a template of wall fragments (basal layer) to the same degree (over 90%) in high concentrations of Na+, K+ (5 X 10(-2) M), Ca2+, Sr2+, and Mg2+ (10(-2) M). At a lower concentration (4 x 10(-5) M) of the cations there was differential adsorption of the protein. Adsorption to the template in the presence of each cation, followed by dilution, also led to differential release of the protein. The adsorption of the protein to the basal layer was correlated with reassembly of the HP layer on the template. The mechanisms seem to be: (i) an ionic strength-dependent reassembly, which results in an HP layer loosely attached to the template (this layer is easily dissociated by decreasing the ionic strength); and (ii) a cation-specific (Ca2+ or Sr2+, but not Mg2+, Na+, or K+) mechanism independent of ionic strength. In this latter case, the specific cations presumably form strong noncovalent "salt" linkages between triads and the basal layer, enabling stable hexagons and the HP layer to be formed.  (+info)

Investigations into the life cycle of the bacterial predator Bdellovibrio bacteriovorus 109J at an interface by atomic force microscopy. (7/76)

Atomic force microscopy was used to image Bdellovibrio bacteriovorus 109J, a gram-negative bacterial predator that consumes a variety of other gram-negative bacteria. In predator-prey communities grown on filters at hydrated air-solid interfaces, repeated cycles of hunting, invasion, growth, and lysis occurred readily even though the cells were limited to near two-dimensional movement. This system allowed us to image the bacteria directly without extensive preparation or modification, and many of the cells remained alive during imaging. Presented are images of the life cycle in two species of prey organisms, both Escherichia coli (a small prey bacterium that grows two-dimensionally on a surface) and Aquaspirillum serpens (a large prey bacterium that grows three-dimensionally on a surface), including high-resolution images of invaded prey cells called bdelloplasts. We obtained evidence for multiple invasions per prey cell, as well as significant heterogeneity in morphology of bdellovibrios. Mutant host-independent bdellovibrios were observed to have flagella and to excrete a coating that causes the predators to clump together on a surface. Most interestingly, changes in the texture of the cell surface membranes were measured during the course of the invasion cycle. Thus, coupled with our preparation method, atomic force microscopy allowed new observations to be made about Bdellovibrio at an interface. These studies raise important questions about the ways in which bacterial predation at interfaces (air-solid or liquid-solid) may be similar to or different from predation in solution.  (+info)

Growth of Spirillum lipoferum at constant partial pressures of oxygen, and the properties of its nitrogenase in cell-free extracts. (8/76)

Spirillum lipoferum, an N2-fixing organism, was grown at constant concentrations of dissolved O2. When supplied with NH4+ aerobically, its doubling time was 1 h; when it fixed N2 microaerophilically, its doubling time was 5-5 to 7 h and the optimal PO2 for growth was 0-005 to 0-007 atm. At its optimal PO2 for growth on N2, S. lipoferum assimilated 8 to 10 mg nitrogen/g carbon substrate used; its efficiency was less at higher PO2 levels. Nitrogenase in cell-free extracts required Mg2+ and Mn2+, and the Fe-protein was activated by Rhodospirillum rubrum activating factor. The nitrogenase had an optimal pH of 7-1 to 7-4 and an apparent Km for acetylene of 0-0036 atm. Extracts of S. lipoferum lost their nitrogenase activity on storage at -18 degrees C, and activity was restored by adding purified Fe-protein from other N2-fixing bacteria.  (+info)

Meaning of Aquaspirillum serpens subsp. serpens medical term. What does Aquaspirillum serpens subsp. serpens mean?
As was mentioned above, Spirillum bacteria possess bipolar tufts of flagella. Although they were first thought to be singular flagella, they were found later to be fascicles of multiple aggregated flagella. It has been suggested that the neutralization of electrical charges is responsible for the aggregation of individual flagella due to an experiment in which the flagellar fascicles were no longer visible when the cell was washed in distilled water and visible again when as low as 0.001 M NaCl or other salts were added (Krieg 1976). Because Spirillum bacteria are large spirilla, they have the typical spirilla flagella long wavelength of over 3 micrometers and usually less than one full wave (this is in contrast to at least one large spirillum and those of medium or small diameter have flagella with several waves and a short wavelength). The fascicles are also very large and have about 75 individual flagella, each separately inserted into the cell and thus individually moving. Instead of being ...

Spherical bacteria are called cocci; the bacteria that have a rodlike shape are known as bacilli; corkscrew shaped bacteria are spirilla; and filamentous is the term for bacteria with a threadlike appearance. Hans Christian Joachim Gram, a Danish microbiologist, developed a method for distinguishing bacteria by their different reaction to a stain. The process of applying Gram s stain is as follows: the bacteria are stained with a violet dye and treated with Gram s solution (1 part iodine, 2 parts potassium iodide, and 300 parts water).. Ethyl alcohol is then applied to the medium; the bacteria will either preserve the blue color of the original dye or they will obtain a red hue. The blue colored bacteria are gram-positive; the red bacteria are identified as gram-negative. Bacteria contain DNA (deoxyribonucleic acid) just like all cells. However, in bacteria the DNA is arranged in a circular fashion rather than in strands. Bacteria also contain ribosomes which, like in eukaryotic cells, provide ...

How to identify internal bleeding. Some types of injuries almost always cause internal bleeding. A gunshot to the gut, for example, is definitely going to make you bleed! However other trauma like falling or getting tackled by a crazed lunatic could still cause that blood loss without any obvious external signs, at least initially.. First off, you should pay attention to any signs of bruising in areas that were otherwise unaffected by the injury. This may indicate that loose blood is pooling near the skin and showing through the layers, similarly to a regular surface bruise.. Secondly, you should be extremely careful to watch for sensory problems, a persistent headache, or any other odd symptoms that might be related to blood in the brain. Even if you otherwise appear fine, long-lasting headaches, sudden and frequent migraines where you had none before, or nausea that is persistent long after any sickness should have been cured.. Thirdly, keep an eye out for blood in any bodily excretions. ...
I just bought a CD at a thrift store, and I was struck by the beautiful artwork printed on the face of the disk. So I wondered how it had been printed. Then I pulled out a number of my CDs and noticed that some were printed differently from others. Unsure of what the options were, I went online and did some research. This is what I found.. Screen Printed CDs. CDs decorated with custom screen printing have a thick surface of ink. The ink has texture and gives an opulent sense to the product. Unfortunately, the surface of a CD has a number of different sections. Printing even the thick silkscreen inks directly over these three distinct portions (the regular surface, mirror band, and stacking ring of the CD) would produce an image with visible shifts from section to section. Therefore, laying down an initial background of white ink is preferable. The white is opaque, so it evens out the differences in the various rings of the CD.. In addition, the white ink also lightens colors printed over this ...
When I was teaching microbiology, Bdellovibrio was always one of my favorite things to lecture about. These bacteria are essentially intracellular parasites of other bacteria. Bdellovibrio has a rather unusual mode of entering its hosts - it uses its flagellum to crash into them at amazing speeds - 160 um/second (ok, that doesnt sound very fast, but when youre only about 1 micron long, thats hauling!) Once inside its host cell, the Bdellovibrio consumes the nutrients inside it, growing longer and longer the whole time. Eventually, when the host cell has run out of nutrients, the long filament will separate into about 3 to 6 individual cells, lyse the membrane of their former host and go off and infect new victims ...

Bdellovibrio is a Gram-negative bacterium that preys upon other Gram-negative bacteria, including many pathogens, and as such has potential as a biocontrol agent. Little is known of the molecular and genetic control of Bdellovibrios attack upon its prey and of the nature of the HI phenotype. Here, we apply microarray technology to monitor changes of gene expression during the initial stages of prey infection to determine which predatory genes are important in this stage and to gain insight into possible regulatory mechanisms controlling the predation process.

Rats can be vectors of many infections, most notably plague and murine typhus, in which their fleas can spread plague bacteria to humans. But other less renowned infections can be spread as well.. Interesting pathogens that can be spread via the bite of rat are Streptobacilus monilloformis and Spirillum minus. These bacteria cause rat bite fever, which has been known to occur for over 2000 years. This disease causes rash and arthritis in the most cases. A select group of cases, however, experience relapsing infection that can lead to endocarditis (infection of the heart valves), meningitis, and sepsis. Untreated, the mortality rate can reach 13%. Mange, the disease mentioned in the movie, is caused by parasitic mites. Sarcoptic mange is basically the canine version of scabies. Rarely, humans can contract sarcoptic mange, but the affliction is usually self-limited in humans as the mite is unable to complete its lifecycle in humans. Rats have their own specific mites, but can also contract ...

A method of forming a programmable conductor memory cell array is disclosed wherein metal and chalcogenide glass are co-sputtered to fill an array of cell vias in a prepared substrate. The prepared substrate is heated above room temperature before the metal and chalcogenide glass film is deposited, and the heating is maintained throughout the deposition. The resulting metal/chalcogenide glass film has good homogeneity, a desired ratio of components, and has a regular surface.
EMPIRE OF CRIME (version 1.0) The war between the rebellious Weave Alliance and the hegemony of the Terran Star Empire has reached a critical point, with either side poised for victory. However, as resources are increasingly seconded to the front lines, the only true victor has been intergalactic organised crime, which has profited and risen to infamy in the absence of any real law enforcement. Tiring of the increasingly dangerous life of a merchant trader, you decide to abandon the world of legitimate business and forge your own path to glory. The game can be played from the viewpoint of three very different perspectives: an association with the upstart Serpens Triumvirate the thankless task of an intergalactic bounty hunter, or an allegiance with the mysterious Mafia. This will be a galaxy in which you will have a multitude of enemies and precious few friends... though who can you really trust, for in a time of near anarchy and golden opportunity, friendship and comradery are the rarest of all ...
Cell migration is a central process in the development and maintenance of multicellular organisms. Tissue formation during embryonic development, wound healing and immune responses all require the orchestrated movement of cells in particular directions to specific locations. Cells often migrate in response to specific external signals, including chemical signals and mechanical signals. Errors during this process have serious consequences, including intellectual disability, vascular disease, tumor formation and metastasis. An understanding of the mechanism by which cells migrate may lead to the development of novel therapeutic strategies for controlling, for example, invasive tumour cells. Due to the highly viscous environment (low Reynolds number), cells need to permanently produce forces in order to move. Cells achieve active movement by very different mechanisms. Many less complex prokaryotic organisms (and sperm cells) use flagella or cilia to propel themselves. Eukaryotic cell migration ...

Among the phototrophic purple sulfur bacteria, these were initially distinguished because they deposit elemental sulfur globules outside the cells, unlike the nEndothiorhodaceae that deposit elemental sulfur inside their cells. Subsequently the extrmely halophilic species were segregated from Ectothiorhodospira and assigned to Halorhodospira. Most species are rods, most often slightly bent rods, vibrios or spirilla that during oxidation of sulfide produce elemental sulfur which is deposited outside the cells; one species, Ectothiorhodospira vacuolata, produces gas vesicles. All of the phototrophic Ectothiorhodospiraceae produce characteristic internal membrane stacks that may constitute a large fraction of the internal volume of these cells ...

Bdellovibrio bacteriovorus HD100 is a highly motile predatory bacterium that consumes other Gram-negative bacteria for its sustenance. Here, we describe the impacts the media viscosity has both on the motility of predator and its attack rates. Experiments performed in polyethylene glycol (PEG) solutions, a linear polymer, found a viscosity of 10 mPa s (5% PEG) negatively impacted predation over a 24-h period. When the viscosity was increased to 27 mPa s (10% PEG), predation was nearly abolished. Tests with three other B. bacteriovorus strains, i.e., 109J and two natural isolates, found identical results. Short-term (2-h) experiments, however, found attack rates were improved in 1% PEG, which had a viscosity of 5.4 mPa s, using bioluminescent prey and their viabilities. In contrast, when experiments were performed in dextran, a branched polymer, no increase in predation was seen even though the viscosity was a comparable 5.1 mPa s. The enhanced attack rates in this solution coincided with a 31% ...

Thus it is called aquatilis serpens, water-snake. Those who are bitten by it swell up, a sickness called by some boa, because it can be cured by the dung of an ox, bos. The idra is a dragon with many heads of the kind that lived on the island, or marsh, of Lerna in the province of Arcadia. It is called in Latin excedra because when one of its heads is cut off, three grow in its place. This is a myth, however, for it is accepted that the hydra was a place where water gushed out, destroying the town nearby; where, as one outlet was closed up, many others burst open. Seeing this, Hercules drained the marsh and so closed the water-spouts. For the word idra is so called from the Greek word for water. The idrus is a worthy enemy of the crocodile and has this characteristic and habit: when it sees a crocodile sleeping on the shore, it enters the crocodile through its open mouth, rolling itself in mud in order to slide more easily down its throat. The crocodile therefore, instantly swallows the idrus ...

Assimilable organic carbon (AOC) was measured combined with molecular weight (MW) distribution during a long time operation of a pilot scale ozonation/BAC (biological activated carbon) process in a water treatment plant in China. The AOC measurement was done on different samples: raw water, water samples after sedimentation, sand filtration, ozonation and BAC filtration. MW distribution variation of AOC during ozonation/BAC process was evaluated. Results showed that AOC was mainly related to the NOM (natural organic matter) with MW , 1 kDa. The fraction of the NOM with MW , 1 kDa corresponds to 53-67% of the dissolved organic carbon (DOC) to all the samples while AOC corresponds to 2.7-5.9% of DOC. So just a small part of the fraction with MW , 1 kDa was AOC. This indicates that ozonation/BAC process removing a large part of DOC will not necessarily result in a great reduction in AOC. ...
