In vivo expression of the nucleolar group I intron-encoded I-dirI homing endonuclease involves the removal of a spliceosomal intron. (1/489)

The Didymium iridis DiSSU1 intron is located in the nuclear SSU rDNA and has an unusual twin-ribozyme organization. One of the ribozymes (DiGIR2) catalyses intron excision and exon ligation. The other ribozyme (DiGIR1), which along with the endonuclease-encoding I-DirI open reading frame (ORF) is inserted in DiGIR2, carries out hydrolysis at internal processing sites (IPS1 and IPS2) located at its 3' end. Examination of the in vivo expression of DiSSU1 shows that after excision, DiSSU1 is matured further into the I-DirI mRNA by internal DiGIR1-catalysed cleavage upstream of the ORF 5' end, as well as truncation and polyadenylation downstream of the ORF 3' end. A spliceosomal intron, the first to be reported within a group I intron and the rDNA, is removed before the I-DirI mRNA associates with the polysomes. Taken together, our results imply that DiSSU1 uses a unique combination of intron-supplied ribozyme activity and adaptation to the general RNA polymerase II pathway of mRNA expression to allow a protein to be produced from the RNA polymerase I-transcribed rDNA.  (+info)

Polymerization of Acanthamoeba actin. Kinetics, thermodynamics, and co-polymerization with muscle actin. (2/489)

The kinetics and thermodynamics for the polymerization of purified Acanthamoeba actin were studied and compared to muscle actin. Polymerization was qualitatively similar for the two actins with a rate-limiting nucleation step followed by rapid polymer extension. Polymerization occurred only above a threshold critical concentration which varied with polymerization conditions for each actin. In the presence of 2 mM MgCl2, nucleation of both actins was rapid and their critical concentrations were similarly low and not detectably dependent on temperature. In 0.1 M KCl, the rates of nucleation of both actins were much slower than when Mg2+ was present and were significantly different from each other. Also, under these conditions, the critical concentrations of Acanthamoeba and muscle actin were significantly different and both varied markedly with temperature. These quantitative differences between the two actins could be attributed to differences in both their enthalpies and entropies of polymerization, Acanthamoeba actin having the more positive deltaH and delta S. Co-polymerization of the two actins was also demonstrated. Overall, however, there were no qualitative differences between Acanthamoeba and muscle actin that would suggest a unique role for the monomer-polymer equilibrium of cytoplasmic actin in cell motility.  (+info)

Timing of nucleolar DNA replication in Amoeba proteus. (3/489)

Light- and electron-microscope autoradiography have been used to follow the incorporation of [3H]thymidine at different stages during the interphase of synchronously growing populations of Amoeba proteus. Two main patterns were found for tritiated thymidine incorporation, i.e. DNA synthesis. The major incorporation was in the central region of the nucleus, but a lesser degree of incorporation occurred in the nucleolar region. The bulk of this nucleolar DNA was found to be late replicating, i.e. it replicated during the G2 phase.  (+info)

Serum antibodies to Balamuthia mandrillaris, a free-living amoeba recently demonstrated to cause granulomatous amoebic encephalitis. (4/489)

Free-living amoebae cause three well-defined disease entities: a rapidly fatal primary meningoencephalitis, a chronic granulomatous amoebic encephalitis (GAE), and a chronic amoebic keratitis. GAE occurs in immunocompromised persons. Recently, another type of free-living amoeba, Balamuthia mandrillaris, has been shown to cause GAE. The finding that this amoeba has caused infection in some healthy children has raised the possibility that humans may lack immunity to B. mandrillaris. Human serum was examined for the presence of surface antibodies specific for this amoeba by immunofluorescence. Sera from adults contained titers of 1/64-1/256 of anti-B. mandrillaris antibodies (IgM and IgG classes), which did not cross-react with other amoebae. Cord blood contained very low antibody levels, but levels similar to those in adults were seen in serum of 1- to 5-year-old children.  (+info)

The role of actin in the temperature-dependent gelation and contraction of extracts of Acanthamoeba. (5/489)

The temperature-dependent assembly and the interaction of Acanthamoeba contractile proteins have been studied in a crude extract. A cold extract of soluble proteins from Acanthamoeba castellanii is prepared by homogenizing the cells in a sucrose-ATP-ethyleneglycol-bis-(beta-aminoethyl ether) N,N'-tetraacetic acid buffer and centrifuging at 136,000 g for 1 h. When this supernate of soluble proteins is warmed to room temperature, it forms a solid gel. Upon standing at room temperature, the gel slowly contracts and squeezes out soluble components. The rates of gelation and contraction are both highly temperature dependent, with activation energies of about 20 kcal per mol. Gel formation is dependent upon the presence of ATP and Mg++. Low concentrations of Ca++ accelerate the contractile phase of this phenomenon. The major protein component of the gel is actin. It is associated with myosin, cofactor, a high molecular weight protein tentatively identfied as actin-binding protein, and several other unidentified proteins. Actin has been purified from these gels and was found to be capable of forming a solid gel when polymerized in the presence of ATP, MgCl3, and KCL. The rate of purified actin polymerication is very temperature dependent and is accelerated by the addition of fragments of muscle actin filaments. These data suggest that Acanthamoeba contractile proteins have a dual role in the cell; they may generate the forces for cellular movements and also act as cytoskeletal elements by controlling the consistency of the cytoplasm.  (+info)

Isolation and electrophoretic analysis of nucleoli, phenol-soluble nuclear proteins, and outer cyst walls from Acanthamoeba castellanii during encystation initiation. (6/489)

A technique is described for isolating nuceoli from Acanthamoeba castellanii. Nuclei isolated by a modification of the technique of F. J. Chlapowski and R. N. Band (1971) are sonicated in a surcrose-Tris-MgSO4-KC1-Triton X-100 buffer and centrifuged on a linear sucrose gradient extending from 1.3 M to 1.5 M with a 2.6 M cushion, at 41000 rpm for 90 min. The only apparent contaminants in the nucleolar preparation are outer cyst walls. A procedure is described for the isolation of chemically pure outer cyst walls, and a comparison of the proteins with the nucleolar preparation reveals that outer cyst walls represent negligible contaminants. The ultrastructure of these isolated nucleoli examined with transmission electron microscopy is found to be identical with that of nucleoli from whole cells, fixed in an identical manner. The 50 nucleolar proteins separated by SDS gel electrophoresis have been examined throughout the growth cycle of Acanthamoeba and into the strat of induced encystment, at which time 10 protein bands disappear, 11 bands are observed to decrease, and 8 are seen to increase in concentration. Phenol-soluble proteins are extracted from the nucleolus which correspond to 29 of the 50 nucleolar proteins, with 17 of these proteins corresponding to nucleolar proteins that change at the onset of encystment. Thes nucleolar proteins are also compared with those of rat liver nucleoli by gel electrophoresis, resulting in the observation that extremely few protein homologies exist between the two. Numerous quantitative and qualitative changes in the gel pattern of phenol-soluble nuclear proteins during early and late log phase growth and the onset of stationary phase were also observed.  (+info)

Signal-mediated nuclear transport in the amoeba. (7/489)

The evolutionary changes that occur in signal-mediated nuclear transport would be expected to reflect an increasing need to regulate nucleocytoplasmic exchanges as the complexity of organisms increases. This could involve changes in both the composition and structure of the pore complex, as well as the cytosolic factors that mediate transport. In this regard, we investigated the transport process in amoebae (Amoeba proteus and Chaos carolinensis), primitive cells that would be expected to have less stringent regulatory requirements than more complex organisms. Colloidal gold particles, coated with bovine serum albumin (BSA) conjugated with simple (large T) nuclear localization signals (NLSs), bipartite (nucleoplasmin) NLSs or mutant NLSs, were used to assay nuclear import. It was found that in amoebae (1) the diameter of the particles that are able to enter the nucleoplasm is significantly less than in vertebrate cells, (2) the simple NLS is more effective in mediating nuclear import than the bipartite NLS, and (3) the nucleoporins do not appear to be glycosylated. Evidence was also obtained suggesting that, in amoebae, the simple NLS can mediate nuclear export.  (+info)

Visualization of actin fibers associated with the cell membrane in amoebae of Dictyostelium discoideum. (8/489)

Amoebae of Dictyostelium discoideum were attached to a surface coated with polylysine, and the upper portion of the cells was sheared off with a stream of buffer. Scanning and transmission electron microscopy showed that the cytoplasmic surface of the exposed membrane was covered with fibers consisting of actin-containing filaments. The actin was identified by its solubility properties and its ability to interact with muscle myosin.  (+info)

Amoebas are published as making food choices as a response to their environment. Like human lymphocytes amoebas surround cytes then digest them. Creating amoebas that are immunotransparent to the human immune system permits them to circulate absent immune attack from the body; creating immunotransparency is a strategy employed with nonhuman mammals thus breeding an immunotransparent amoeba may be literally millions or billions of times easier. Amoebas are publishes as making food choice comparisons; it is possible to make them tissue type specific or possibly even educated to prefer a diseased tissue type specific to a particular person.. The amoebas can be bred or trained to recognize then eat tissue types with particular surface chemistry such as cancer cytes or atherosclerotic lesions.

A study published in Nature Communications from researchers at the University of Geneva and Baylor College of Medicine show the amoeba Dictyostelium discoideum uses antimicrobial defense systems akin to phagocytes of the human innate immune system, and it evolved these defenses much earlier than initially thought.. D. discoideum is a soil living amoeba often referred to as "slime mold". These social amoebas tend to aggregate together, particularly during times of low resources, to form a mobile "slug" composed of ~100,000 individual amoebas. The slugs role is to disperse spores on the wind to seed new areas containing better resources. Within this slug, 80% of the amoeba will become spores, while approximately 20% will sacrifice themselves to form a stalk, a primitive spore dispersal method. About 1% of the amoeba though takes on defense duties by protecting the stalk/spore dispersion mechanism from invading bacteria.. It is this 1% that the researchers were interested in.

Free-living Amoebae are unicellular protozoans common in aquatic ecosystems, which are also known to colonize Human created water systems such as water supply systems and swimming pools. Whilst in some ways these organisms can be helpful, consuming a range of Bacterial, Viral and Fungal pathogens, they have also been shown to cause a range of infections themselves, and can themselves be infected by a variety of pathogenic Bacteria, such as Legionella pneumophila, Mycobacteria, Pseudomonas aerugionosa and Acinetobacter baumannii. Whilst most Bacteria are consumed and digested by the Amoebae, these pathogenic species have been shown to be able to resist digestion, instead surviving within the Amoebae, where they receive protection from biocides and antibiotics, later emerging to cause infections in Humans. ...

Scientists used to think amoebas had always produced asexually, but it turns out a long time ago, there were mommy amoebas and daddy amoebas, and when they loved each other very, very much, you got little baby amoebas. After a few million years or so, however, the amoebas decided it just wasnt worth the effort and it made a lot more sense reproducing without getting into the whole, "You forgot our anniversary" and "do these vacuoles make my protist look fat?" thing. What this means is, while we used to believe that sexual reproduction represented an advance over asexual, in fact, its the other way around. This news is disappointing to the rest of us who still view sex as at least mildly entertaining, but maybe when youve been on the planet as long as amoeba have, you start to see things differently ...
Free-living amoebae (FLA) are parasites within both humans and animals causing a wide range of symptoms and act as hosts of, and vehicles for phylogenetically diverse microorganisms, called endocytobionts. The interaction of the FLA with sympatric microorganisms leads to an exceptional diversity within FLA. Some of these bacteria, viruses, and even eukaryotes, can live and replicate intracellularly within the FLA. This relationship provides protection to the microorganisms from external interventions and a dispersal mechanism across various habitats. Among those intracellularly-replicating or -residing organisms there are obligate and facultative pathogenic microorganisms affecting the health of humans or animals and are therefore of interest to Public Health Authorities. Mimiviruses, Pandoraviruses, and Pithoviruses are examples for interesting viral endocytobionts within FLA. Future research is expected to reveal further endocytobionts within free-living amoebae and other protozoa through co
Based in Chassieu - France, AMOEBA develops a biological biocide capable of eliminating waterborne bacterial risk (legionella, pseudomonas, listeria, etc.). This entirely natural solution is presented as an alternative to the chemical treatments traditionally used in the industrial sector and complies with the new regulations in terms of environmental chemical emissions. In a worldwide market for chemical biocides estimated to be worth 21 bn€(1), AMOEBA is today concentrating on the segment of industrial air-cooled towers (ACT) estimated to be worth 1.7 €bn(2). AMOEBA is continuing with its regulatory procedures so as to obtain provisional MA for all European countries for the "Air Cooled Towers" application. AMOEBA is quoted on compartment C of the Euronext Paris stock exchange and joined the CAC® Small index on 21st September 2015. For more information: www.amoeba-biocide.com.

Protists, Pseudopods are unicellular organisms characterized by movement using pseudopods, which can act in both locomotion and feeding behaviors. These slow movers are easy to follow and observe.
This class was anticipated by some biologists like Jahn, who grouped all amoebae with granular pseudopodia together,[1] but most split the lobose amoebae into testate Testacealobosia and naked Gymnamoebia. These latter are polyphyletic, but molecular trees by Bolivar et al.[2] identified a core monophyletic subgroup. Subsequent studies showed the testate lobose amoebae belong to the same group, which was thus renamed Lobosea sensu stricto[3] or Tubulinea.[4]. ...
In material collected from Tannoch Loch, Dunbartonshire, a large free-living, hitherto undescribed amoeba was found. Individual specimens vary in length from 420 to 500µ and in width from 70 to 140µ. Viewed over a black background this amoeba looks dense, white, and opaque, while in transmitted light it has a dusky, almost black, hue, due to the presence in the endoplasm of a large number of small crystals uniform in size, slender and pointed at both ends. There is always a uroid at the hinder end surrounded by bits of debris. The one large nucleus is without a karyosome but has masses of chromatin scattered through the nuclear substance. As a rule there is only one large contractile vacuole, but occasionally a few small ones may be seen at the hinder end. A certain number of nutritive spheres are always present. The author considers this amoeba to be a new species and names it Amoeba taylorae.. ...
Rivka Bracha and colleagues in the lab of Prof. David Mirelman in the Biological Chemistry Department had shown that expression of the gene coding for the toxic protein could be prevented by inserting a plasmid (a small loop of DNA) containing a copy of a specific part of that gene into the amoeba cell nucleus. Introducing the plasmid led to the modification of DNA "packing" proteins, causing the DNA-protein packages to become more tightly coiled - something like a tangled telephone cord - and causing an irreversible silencing of gene expression. In a recent paper published in PLoS Pathogens, the Weizmann scientists report the silencing of two additional virulence genes in the same amoebae using a similar plasmid-induced principle. The disabled amoebae, though rendered harmless, still display the same repertoire of surface antigens (markers recognized by the immune system) as the disease-causing strain. The scientists now plan to test the ability of these silenced amoebae to serve as a live ...
Liver abscesses are always preceded by intestinal colonization, which may be asymptomatic. Blood vessels may be compromised early by wall lysis and thrombus formation. Trophozoites invade veins to reach the liver through the portal venous system. E. histolytica is resistant to complement-mediated lysis-a property critical to survival in the bloodstream. In contrast, E. dispar is rapidly lysed by complement and is thus restricted to the bowel lumen. Inoculation of amebas into the portal system of hamsters results in an acute cellular infiltrate consisting predominantly of neutrophils. Later, the neutrophils are lysed by contact with amebas, and the release of neutrophil toxins may contribute to necrosis of hepatocytes. The liver parenchyma is replaced by necrotic material that is surrounded by a thin rim of congested liver tissue.The necrotic contents of a liver abscess are classically described as "anchovy paste," although the fluid is variable in color and is composed of bacteriologically ...
Protozoa are single celled animals that feed primarily on bacteria, but also eat other protozoa, soluble organic matter, and sometimes fungi. They are several times larger than bacteria typically ranging from 5 to 500 µm in diameter. Protozoa are classified into three groups based on their shape. Ciliates are the largest and move by means of hair like cilia. They eat the other two types of protozoa, as well as bacteria. Amoebae also can be quite large and move by temporary foot. Amoebae are further divided into testate amoebae that make a shell like covering and naked amoebae without a covering. Flagellates are the smallest of the protozoa and use a few whip like flagella to move.. In amoeba, actin and myosin are organized into a three dimensional network. Locomotion in amoeba is brought about by the continuous assembly and disassembly of actin and myosin containing complexes. As a result of this activity, pseudopodia are formed at the front end of the moving cell. Movement in the ciliates is ...
I thought todays Friday Science entry would be about my favorite amoebae and yesterdays seminar speaker. My boss was the seminar host for yesterday and she invited Dr. Adam Kuspa to speak about his current research with Dictyostelium (Dicty), the same organism we work with. Dicty are a soil amoeba that eats things like bacteria and yeast. They crawl around in the ground individually hunting for food and dividing until they run out of food. Then all the dicty cells in that area migrate together to form a slug (but not the kind of slug that leave the slime trails on your side walk). We are talking about 50,000 cells coming together and moving through the soil until they find a good spot to sort of plant themselves, usually some place kind of sunny. Then they form a stalk with a fruiting body on the end. The fruiting body is full of spores and when the food source returns or conditions are good, the spores can germinate back into single dicty cells. Pretty cool.. There are certain dicty cells in ...
Amoeboid motility requires spatiotemporal coordination of biochemical pathways regulating force generation and consists of the quasi-periodic repetition of a EPZ-6438 motility cycle driven by actin polymerization and actomyosin contraction. tensional stress and that wild-type cells develop two opposing EPZ-6438 "pole" forces pulling the front and back toward the center whose strength is modulated up and down periodically in each cycle. We demonstrate that nonmuscular myosin II complex (MyoII) cross-linking and motor functions have different roles in controlling the spatiotemporal distribution of traction forces the changes in cell shape and the duration of all the phases. We show that the time required to complete each phase is dramatically increased in cells with altered MyoII motor function demonstrating that it is required not only for contraction but also for protrusion. Concomitant loss of MyoII actin cross-linking leads to a force redistribution throughout the cell perimeter pulling inward ...
Of the 300 or so cases of this disease world-wide, only seven or so have been survived (Jain et al, 2002). The drug of choice has been amphotericin B (Anderson & Jamieson, 1972;Seidel et al, 1982;Jain et al, 2002 ) it is usually given intravenously at 1mg/kg/day (see Shenoy et al, 2002). In the cases where patients have survived early diagnosis has been crucial. Symptoms are generally like bacterial meningitis but with no bacteria in the cerebrospinal fluid, the presence of amoebae can however be detected by observation of the CSF under a microscope. The incubation period is usually between 3 and 8 days and the patient usually dies 7-10 days after infection (Butt, 1966; Anderson & Jamieson, 1972; Barnett et al, 1996). ...

The skeleton of the eukaryotic cell is internal; it is formed by a complex of protein tubules called the cytoskeleton. The internal placement of the cytoskeleton means the surface exposed to the environment is a pliable membrane rather than a rigid cell wall. The combination of an internal framework and a nonrigid outer membrane expands the repertory of motion and activity of the eukaryotic cell. For example, the cell can contract, as does a muscle cell. The key step in the evolution of eukaryotes is the development of the cytoskeleton. Since the cells structural integrity is maintained by the cytoskeleton, the cell can afford to have a fluid outer membrane. Unlike bacteria which are aggregates of proteins living inside their hard symmetrical containers, eukaryotic cells such as amoeba are real individual entities, and the cell is the flexible body of the creature. Like any animal, an amoeba can control its body in an organized and purposeful way. At the core of this organized and coordinated ...

Perhaps more so than any other band, Korn is inextricably linked to the nu-metal movement of the late 1990s; a movement they helped spearhead and sonically define, whether they like that to be their legacy, or not. Originating in Bakersfield, California, circa 1993, Korn was born when vocalist Jonathan Davis and guitarist Brian Head Welch joined forces with guitarist James Munky Shaffer, bassist Reginald Fieldy Arvizu and drummer David Silveira, all three of whom had played in a defunct funk metal band named L.A.P.D. With the help of producer Ross Robinson, the quintet unknowingly codified the building blocks of nu-metal on their hugely influential self-titled debut from 1994 (its dissonant, down-tuned guitars, angst-ridden vocals, and intensely rhythmic approach - everything but the DJ and turntables, in fact) and its even more successful follow-up, Life is Peachy (1996). But it was 98s Billboard Chart-topping Follow the Leader that took Korn stratospheric (on the strength of an ...
On average I would venture to say about one half the size of most, not all, amoebae. Most of the trypanosmes I have listed are in the range of 25 microns up to about 65 microns (um).

Most of the amoeba normally encounted by myself now, are from 80um up to about 230um. That is where I am getting my size average in relation to the trypanosomes. Sizes of micro organisms are so varied by species, that to say one is relatively larger than the next or smaller than the next on average, would be in my opinion be difficult to say ...

I also wouldnt call the Amoebas a prototype. Just because the outer casing is not machined per say doesnt mean its not a finished product. Im sure a lot of thought went into these builds.

That includes drivers, mounts, LEDs and reflectors. For someone ( like Scar ) who does this kind of a thing as a side-line and does all the work himself ( as far as I know ), thats saying a lot. Ill also add that as long as Ive been hanging around on this forum, Ive never seen or heard anyone speak out or claim to have a problem with one of the Amoebas.

The relationship between Ca++ and pinocytosis was investigated in Amoeba proteus. Pinocytosis was induced with 0.01% alcian blue, a large molecular weight dye which binds irreversibly to the cell surface. The time-course and intensity of pinocytosis was monitored by following the uptake of [3H]SUCROSE. When the cells are exposed to 0.01% alcian blue, there is an immediate uptake of sucrose. The cells take up integral of 10% of their initial volume during the time-course of pinocytosis. The duration of pinocytosis in the amoeba is integral of 50 min, with maximum sucrose uptake occurring 15 min after the induction of pinocytosis. The pinocytotic uptake of sucrose is reversibly blocked at 3 degrees C and a decrease in pH increases the uptake of sucrose by pinocytosis. The process of pinocytosis is also dependent upon the concentration of the inducer in the external medium. The association between Ca++ and pinocytosis in A. proteus was investigated initially by determining the effect of the ...
Balamuthia mandrillaris is a free-living amoeba that causes Balamuthia amoebic encephalitis, a fatal disease in humans and animals. Its ecology and risk to humans is largely unknown, although Balamuthia infections have been mostly associated with soil-related activities. Ecology studies are hampered by difficulty in isolating the amoeba by culture methods used for other free-living amoebae. In this study, a DNA extraction method and nested PCR was developed for rapid detection of B. mandrillaris from environmental samples, without needing primary culturing. More than 25% of soil samples were positive for B. mandrillaris, predominantly those from high temperature countries. Additionally, B. mandrillaris was frequently found in thermally polluted water, with almost 50% of samples positive. To facilitate the isolation of B. mandrillaris from environmental samples, immunomagnetic separation with B. mandrillaris antibodies was investigated. For this, poly- and monoclonal antibodies were produced and ...
TY - CHAP. T1 - Environmental amoebae and mycobacterial pathogenesis. AU - Harriff, Melanie. AU - Bermudez, Luiz E.. PY - 2008. Y1 - 2008. N2 - Environmental amoebae have been shown to be a host to pathogenic mycobacteria. Mycobacterium avium, Mycobacterium marinum, and Mycobacterium peregrinum can all grow inside Acanthamoeba and other environmental amoebae. Once ingested by Acanthamoeba, M. avium upregulates a number of genes, many of them similar to genes upregulated upon phagocytosis of M. avium by macrophages. Mycobacteria ingested by amoebae grow intracellularly, acquiring an invasive phenotype, evident when the bacterium escapes the infected amoeba. Once inside of amoeba, it has been shown that mycobacteria are protected from antibiotics and disinfectants, such as chlorine. This chapter describes methods employed for the study of the interaction of M. avium and Acanthamoeba.. AB - Environmental amoebae have been shown to be a host to pathogenic mycobacteria.

A species of amoeba that grows in warm freshwater like lakes, rivers or hotsprings called Naegleria fowleri can damage your brain. When a person takes in the amoeba contaminated water through his nose , the ameba travels up the nose to the brain where it destroys the brain tissue.. The infection is not spread by drinking the water but only by inhaling it. These amoebae are found in geothermally hot water sources like a hot water spring as well as in warm water coming out of industrial plants. Naegleria fowleri grows best at higher temperatures up to 115°F (46°C) and can survive for short periods at higher temperatures. ...
The amoeba thrives in warm, stagnant water but may be present in any body of fresh water. A combination of lower water levels, high temperatures and stagnant or slow-moving water may produce higher concentrations of the amoeba.. Infection can occur when water containing the amoeba is forced up the nose when participating in water-related activities. The organism has also been found in tap water and can be introduced to the brain when tap water is used for nasal irrigation or sinus flushes. Symptoms may include severe headache, high fever, stiff neck, nausea and vomiting.. The amoeba does not live in salt water or in swimming pools and hot tubs that are properly cleaned, maintained and treated with chlorine.. LISTEN: ...

Tuberculosis remains a major threat to human health accounting for 2 million annual deaths worldwide. M. bovis causes TB in cattle which is a serious issue in the UK. Mycobacteria are widely distributed in the environments that are also colonized by free living amoebae. In the present study, free-living amoeba (A. castellanii) has been used to study the genetic factors required for the intracellular survival of M. bovis. Role of region of difference 1 (RD1), isocitrate lyase (Rv0467), ClgR (Rv2745) and the VapC (Rv2548) toxin-antitoxin system was examined for survival in amoebae. While the role of RD1 in mycobacterial survival in amoebae could not be observed, isocitrate lyase and a transcriptional regulator (ClgR) might play some part in survival of M. bovis in A. castellanii. It was found that although the mycobacteria were able to remain inside the amoebae vacuoles, they were unable to control the pH as the vacuoles remained acidic. This is very interesting as it is in contrast to macrophages ...
By Luis Puga. After 25 years as a dentist in Winsted, Dr. James Neff said that the town he came to in 1974 has become his home. Stationed at McCord Air Force Base for two years beforehand as a captain in the service, Neff said he and his family had a list of nine criteria for a community they wanted to live in. Ultimately his reasons for choosing Winsted were numerous. I think the location near the metro area was important to us. Also, that it was definitely rural because people tend to be friendlier and its a great place to raise a family, he said. It seemed like a good, Christian community. Thats important to me. He adds that the community needed a dentist at the time and saw an opportunity in that need.. Neff opened his office in Winsted on June 24, 1974 on 2nd Street South.. At the time, it was just him and two staff members; one dental assistant and a business receptionist.

The M.L.D. per kilogram by intraperitonial injection for the mouse is about 0.126 gram.. Toxic doses of conessine produce paralysis of the central nervous system in frogs but this effect is not appreciable in mammals. With intravenous injections death is mainly due to cardiac failure.. Small doses of conessine produce a slight rise of blood pressure without any effect on the respiration.. Large doses cause a fall due mainly to slowing and weakening of the heart. Conessine has no effect on the coronary vessels in the isolated rabbits heart but it constricts the renal vessels and dilates those of the intestine.. Conessine has no appreciable action on the voluntary muscle of the frog. The smooth muscle of the intestine and uterus is stimulated by conessine.. Conessine kills Paramoecium caudatum and Amoebae proteus in concentrations of 1:40,000 and 1: 8000 ...
In this study, we used a novel approach to detect internalized mycobacteria in environmental protozoa from badger latrines. Acid-fast micro-organisms were visualized in isolated amoebae, although we were unable to identify them to species level as no mycobacteria were grown from these samples nor was M. bovis detected by IS6110 PCR. Co-incubation of Acanthamoeba castellanii with virulent M. bovis substantially reduced levels of bacilli, indicating that the amoebae have a negative effect on the persistence of M. bovis. ...

TY - JOUR. T1 - Evolution of size and pattern in the social amoebas. AU - Schaap,P.. N1 - MEDLINE® is the source for the MeSH terms of this document.. PY - 2007/7. Y1 - 2007/7. N2 - A fundamental goal of biology is to understand how novel phenotypes evolved through changes in existing genes. The Dictyostelia or social amoebas represent a simple form of multicellularity, where starving cells aggregate to build fruiting structures. This review summarizes efforts to provide a framework for investigating the genetic changes that generated novel morphologies in the Dictyostelia. The foundation is a recently constructed molecular phylogeny of the Dictyostelia, which was used to examine trends in the evolution of novel forms and in the divergence of genes that shape these forms. There is a major trend towards the formation of large unbranched fruiting bodies, which is correlated with the use of cyclic AMP (cAMP) as a secreted signal to coordinate cell aggregation. The role of cAMP in aggregation arose ...
Marc Korn went North to Alaska. The 56-year-old former owner of Fairchild Manor in Lewiston, Marc Irwin Korn, is alive and well and working as a consultant in Alaska. Readers may recall that Korn advertised on the back cover of the Niagara Falls Reporter for about three months in 2011. Since we had extended him credit for the advertising, we hardly expected that, upon our gentle urging for payment, Korn would present us with bogus checks. But writing bad checks is almost a disease with the soft spoken, weasel of a man with a badly-dyed, misshapen hair transplant. A few months ago, C Care Services, a company that offers in-home non-medical care services, hired Korn, then a consultant for Global Resources in Northbrook, Ill., to come to Anchorage, Alaska, to help them out for a reported $250 per hour. Several people, after filing complaints against Korn with various agencies in Alaska, contacted the Reporter. They allege that Korn devised a plan to help the company defraud Alaska Medicaid. The ...
CDC officials say ingesting water containing the amoeba is harmless because it cannot infect a person through the digestive system, but the contaminated water can prove fatal if it comes into contact with nasal passages, which is how it travels to the brain. A four-year-old Mississippi boy contracted the amoeba while visiting St. Bernard Parish last year and later died.
MISSION, Kan. -- An extremely rare brain-eating amoeba has killed a nine-year-old girl from Johnson County. Hally Yust, 9, from Spring Hill was an avid skier and died two days ago on Wednesday. The amoeba is found in fresh water.
ARES AMOEBA AM-015 BK STUBBY BADGER CQC - Here is the latest addition from Ares Amoeba, the AM-015 CQC/CQB stubby badger This new AEG comes with some really great features.
Amoebas are fascinating single-celled organisms. They typically move about by having their internal fluid (their cytoplasm) flow around and they eat their food by surrounding and digesting it with their body, in a process called phagocytosis. Some amoeba are parasites, such as Entamoeba histolytica, which can infect people and cause a potentially fatal diarrheal disease … Continue reading ». ...

Abstract Trophozoites and cysts of an Acanthamoeba were repeatedly isolated from the corneal scrapings of a patient suffering from acute ulceration of the right eye. The ameba was cloned and cultivated axenically in a proteose peptone-yeast extract-glucose medium. At a later date the organism was identified as A. polyphaga on the basis of its morphologic characteristics, especially those of cysts. Experimental studies on the in vitro interactions of this organism with monkey kidney tissue culture (Vero line) and its pathogenicity to mice indicated that it was a low virulent strain. When large numbers of amebae (25,000+) were inoculated into Vero cell cultures, cytopathic effects (CPE) were noticed within 5 to 6 days. The CPE consisted of cell shrinkage, nuclear pycnosis, and discontinuity of cell sheet, and the cell culture was totally destroyed in 8 to 10 days. When 20,000+ amebae were instilled intranasally into each of 20 2-week-old mice, only 1 mouse died, on the 28th day. Amebae were isolated from

The Louisiana Department of Health and Hospitals (DHH) notified local officials Monday of the amoeba in at least one hydrant as a result of sample testing.
Two organisms were identified from the top of the culture and from the bottom of the culture for a total of four identified organisms. The two organisms identified from the top of the culture were paramecium and amoeba. The paramecium was colorless and was the shape of an elongated oval. It had two vacuoles, a micro and macronucleus, and also had cilia surrounding its outer covering. The paramecium was 50µm long and was a protist. The amoeba had an irregular shape and was mostly colorless, except for the brown-green coloring that surrounded most of its numerous organelles. The amoeba also had a contractile vacuole that was constantly expelling water from the organism. The amoeba was 25µm in length and was a protist. The two organisms that were identified near the bottom of the culture in the sediment and plant matter were chlamydomonas and colpidium. Two chlamydomonas were observed in the same area; both were unicellular, colorless, and roughly cube-shaped. Both also had one pair of flagella, ...
St. Bernard Parish officials on Thursday will end a state-mandated chlorine burn instituted after brain-eating amoeba was found in the communitys water system in July.
The brain-eating amoeba that killed three people this summer is an organism that thrives in warm fresh water and can be found in lakes, rivers, hot springs and soil, according to the Centers for Disease Control and Prevention.
Tests of a Louisiana parishs water supply confirmed the presence of a rare brain-eating amoeba blamed for last months death of a 4-year-old boy.
Brain-eating amoeba Death by brain-eating amoeba is a problem and not just for people living in far-off countries. A 4-year-old boy recently died after becoming infected with the amoeba found in tap water in Louisiana. Last year, two people in the state contracted the brain-eating amoeba by using neti pots to irrigate their sinuses. This week, a 12-year-old Arkansas girl is lucky to be alive, and back at home, after surviving an infection she picked up after a trip to a water park.. less ...
Naegleria fowleri is a free-living amoeba that causes primary amoebic meningoencephalitis (PAM). In the United States, there are between 0-8 cases of PAM per year, with approximately 98% of cases resulting in death. High case fatality and limited treatment options highlight the need for better understanding of this organism in terms of its biology and pathogenicity. Transfection is a useful tool that allows for the study of gene function, but at present no transfection systems have been established for N. fowleri. This study attempts to establish a transfection system for N. fowleri using the piggyBac vector, with the hope of eventually using the piggyBac transposon system to identify novel genes related to pathogenicity in N. fowleri. To accomplish this, 5 and 3 regulatory regions for genes in the N. fowleri genome were amplified and inserted into a piggyBac vector with a GFP reporter gene via molecular cloning, and vectors introduced to the amoeba via electroporation. Although no GFP was visualized
The Gram-negative bacterium Campylobacter jejuni is able to enter, survive and multiply within the free living amoeba Acanthamoeba polyphaga, but the molecular mechanisms behind these events are still unclear. We have studied the uptake and intracellular trafficking of viable and heat killed bacterial cells of the C. jejuni strain 81-176 in A. polyphaga. We found that viable bacteria associated with a substantially higher proportion of Acanthamoeba trophozoites than heat killed bacteria. Furthermore, the kinetics of internalization, the total number of internalized bacteria as well as the intracellular localization of internalized C. jejuni were dramatically influenced by bacterial viability. Viable bacteria were internalized at a high rate already after 1 h of co-incubation and were observed in small vacuoles tightly surrounding the bacteria. In contrast, internalization of heat killed C. jejuni was low at early time points and did not peak until 96 h. These cells were gathered in large ...

Naegleria fowleri, colloquially known as the "brain-eating amoeba", is a species of the genus Naegleria, belonging to the phylum Percolozoa. It is a free-living, bacteria-eating amoeba that can be pathogenic, causing a fulminant (sudden and severe) brain infection called naegleriasis, also known as primary amoebic meningoencephalitis (PAM). This microorganism is typically found in bodies of warm freshwater, such as ponds, lakes, rivers, and hot springs. It is also found in the soil near warm-water discharges of industrial plants, and in unchlorinated or minimally-chlorinated swimming pools. It can be seen in either an amoeboid or temporary flagellate stage. Naegleria fowleri is a thermophilic (heat-loving), free-living amoeba. It is found in warm and hot freshwater ponds, lakes and rivers, and in the very warm water of hot springs. As the water temperature rises, its numbers increase. The amoeba was identified in the 1960s in Australia but appears to have evolved in the United States. N. fowleri ...
Primary amoebic meningoencephalitis (PAM) is a rare but fulminant disease leading to diffuse haemorrhagic necrotising meningoencephalitis, and has a very poor prognosis.1 Naegleria fowleri is the causative agent. At Townsville Hospital, our first confirmed case of PAM was an 18-month-old girl from a rural location in North Queensland who presented with fever, seizures and an altered level of consciousness.2 Organisms resembling Naegleria spp. were seen on microscopy of cerebrospinal fluid (CSF). Despite aggressive therapy with multiple antimicrobial agents, the patient died within 72 hours of presentation. An older sibling of the patient had presented with a similar syndrome several years earlier and had died of an undifferentiated meningitic illness. The sibling was retrospectively suspected to also have had PAM.2. Our second confirmed patient presented in early 2015. A previously well 12-month-old boy from a nearby West Queensland cattle-farming area had had a 36-hour history of fevers, ...
Free-living amebas, usually harmless protozoan residents of soil and water, can cause three distinct, occasionally devastating, human illnesses. Primary amebic meningoencephalitis (PAM) is a disease of the previously healthy and is caused by Naegleria fowleri. Granulomatous amebic encephalitis (GAE) is caused by Acanthamoeba species or Balamuthia mandrillaris, and occurs in both healthy and immunocompromised persons. In wealthier countries, contact lens users may suffer from chronic amebic keratitis, also caused by Acanthamoeba. While these diseases are found worldwide, they are more common in tropical and subtropical regions. ...
Case histories are presented of 2 individuals (a 5-year-old girl and 64-year-old man) who developed encephalitis caused by the free-living amoeba Balamuthia mandrillaris Both individuals survived after diagnosis and initiation of effective antimicrobial therapy. Immunostaining for Balamuthia-specific antibody levels identified the causative agent of the infections. Antimicrobial therapy with flucytosine, pentamidine, fluconazole, sulfadiazine, and a macrolide antibiotic (azithromycin or clarithromycin) was initiated. Phenothiazines (thioridazine and trifluoperazine) were also used. Both patients recovered, and there was no evidence of recrudescence of the disease at 2 and 6 years after onset of symptoms. Awareness of Balamuthia as the causative agent of encephalitis and early initiation of antimicrobial therapy were critical to the recovery of both patients. Although optimal antimicrobial therapy for Balamuthia amoebic encephalitis has yet to be determined, the antimicrobials used in these 2 ...

  • From comparisons of molecular data and from life history data, it is clear that the amoeboid body form is an adaptive form and that the amoebae are polyphyletic. (tolweb.org)
  • While amoebas commonly are presented as reproducing asexually, some researchers have argued that analysis of the evidence of sexual reproduction in several amoeboid lineages leads to the conclusion that amoeboid lineages are anciently sexual and asexual groups are a more recent development. (newworldencyclopedia.org)
  • Microbiologists often use the terms "amoeboid" and "amoeba" interchangeably for any organism that exhibits amoeboid movement. (wikipedia.org)
  • Free-living amoebae may be "testate" (enclosed within a hard shell), or "naked" (a.k.a. gymnamoebae, lacking any hard covering). (wikipedia.org)
  • The shells of testate amoebae may be composed of various substances, including calcium, silica, chitin, or agglutinations of found materials like small grains of sand and the frustules of diatoms. (wikipedia.org)
  • Amoeba reproduction is an asexual event in which the organism doubles its genetic material, creates two nuclei and then sets about dividing into two cells. (scientificamerican.com)
  • Dave Mosher for Scientific American states that modern scientists have recently begun to question whether amoebas are actually purely asexual or if the reproductive behavior scientists have studied in the past is merely the result of controlled laboratory conditions. (reference.com)
  • Despite their evident pleomorphism which comes from being able to emit and resorb extensions of cytoplasm, active amoebae do have a front and a back. (tolweb.org)
  • Amoebae move and feed by using pseudopods, which are bulges of cytoplasm formed by the coordinated action of actin microfilaments pushing out the plasma membrane that surrounds the cell. (wikipedia.org)
  • If p is the probability that a single amoeba's descendants will die out eventually, the probability that N amoebas' descendants will all die out eventually must be p^N, since each amoeba is independent of every other amoeba. (braingle.com)
  • Because of their simplistic nature, amoebas are often referenced in discussions of evolution, as those advocating design, question how organisms as simple as amoebas can evolve by accident or chance to the great complexity seen in life today. (factbites.com)

  • Amoeba are simple animals and their whole surface is in contact with the water that surrounds them and which contains oxygen. (factbites.com)
  • Amoeba is an interior lighting concept derived from the shape and movement of an amoeba. (behance.net)
  • The amoeba "breathes" using this membrane - oxygen gas from the water passes in to the amoeba through the cell membrane and carbon dioxide gas leaves through it. (factbites.com)
  • As the amoeba uses up oxygen on the inside, the concentrate of oxygen lowers, so there is less on the inside than in the water outside. (factbites.com)
  • When an ameba is divided artificially, the portion containing the nucleus forms a new cell membrane and continues as a whole animal, while the other portion lives only as long as its present food supply lasts, ultimately dying, since it cannot ingest food or reproduce. (encyclopedia.com)
  • This describes the act when the nucleus of one cell is spurred to divide into an equal and exact replica of itself within the same cell walls, after which the two nuclei separate into their own individual cells, resulting in two sovereign yet genetically identical amoebas. (reference.com)
  • The amoeba is usually found in surface water such as rivers and lakes. (factbites.com)
