    Hydrogen was produced from steam-exploded corn stover by using a combination of the cellulolytic bacterium Clostridium cellulolyticum and non-cellulolytic hydrogen-producing bacteria. The highest hydrogen yield of the co-culture system with C. cellulolyticum and Citrobacter amalonaticus reached 51.9 L H2/kg total solid (TS). The metabolites from the co-culture system were significantly different from those of the mono-culture systems. Formate, which inhibits the growth of C. cellulolyticum, could be consumed by the hydrogen-evolving bacteria, and transformed into hydrogen. Glucose and xylose were released from corn stover via hydrolysis by C. cellulolyticum and were quickly utilized in dark fermentation with the co-cultured hydrogen-producing bacteria. Because the hydrolysis of corn stover by C. cellulolyticum was much slower than the utilization of glucose and xylose by the hydrogen-evolving bacteria, the sugar concentrations were always maintained at low levels, which favored a high hydrogen molar yield.

    Background: The model bacterium Clostridium cellulolyticum efficiently hydrolyzes crystalline cellulose and hemicellulose, using cellulosomes to degrade lignocellulosic biomass. Although it imports and ferments both pentose and hexose sugars to produce a mixture of ethanol, acetate, lactate, H2 and CO2, the proportion of ethanol is low, which impedes its use in consolidated bioprocessing for biofuels. Therefore genetic engineering will likely be required to improve the ethanol yield. Random mutagenesis, plasmid transformation, and heterologous expression systems have previously been developed for C. cellulolyticum, but targeted mutagenesis has not been reported for this organism. Results: The first targeted gene inactivation system was developed for C. cellulolyticum, based on a mobile group II intron originating from the Lactococcus lactis L1.LtrB intron. This markerless mutagenesis system was used to disrupt both the paralogous L-lactate dehydrogenase (Ccel_2485; ldh) and L-malate dehydrogenase (Ccel_0137; mdh) genes, distinguishing the overlapping substrate specificities of these enzymes. Both mutations were then combined in a single strain. This double mutant produced 8.5-times more ethanol than wild-type cells growing on crystalline cellulose. Ethanol constituted 93% of the major fermentation products (by molarity), corresponding to a molar ratio of ethanol to organic acids of 15, versus 0.18 in wild-type cells. During growth on acid-pretreated switchgrass, the double mutant also produced four-times as much ethanol as wild-type cells. Detailed metabolomic analyses identified increased flux through the oxidative branch of the mutant s TCA pathway. Conclusions: The efficient intron-based gene inactivation system produced the first gene-targeted mutations in C. cellulolyticum. As a key component of the genetic toolbox for this bacterium, markerless targeted mutagenesis enables functional genomic research in C. cellulolyticum and rapid genetic engineering to

    2012-02-01

    D-psicose 3-epimerase (DPEase) is demonstrated to be useful in the bioproduction of D-psicose, a rare hexose sugar, from D-fructose, found plenty in nature. Clostridium cellulolyticum H10 has recently been identified as a DPEase that can epimerize D-fructose to yield D-psicose with a much higher conversion rate when compared with the conventionally used DTEase. In this study, the crystal structure of the C. cellulolyticum DPEase was determined. The enzyme assembles into a tetramer and each subunit shows a (β/α)(8) TIM barrel fold with a Mn(2+) metal ion in the active site. Additional crystal structures of the enzyme in complex with substrates/products (D-psicose, D-fructose, D-tagatose and D-sorbose) were also determined. From the complex structures of C. cellulolyticum DPEase with D-psicose and D-fructose, the enzyme has much more interactions with D-psicose than D-fructose by forming more hydrogen bonds between the substrate and the active site residues. Accordingly, based on these ketohexose-bound complex structures, a C3-O3 proton-exchange mechanism for the conversion between D-psicose and D-fructose is proposed here. These results provide a clear idea for the deprotonation/protonation roles of E150 and E244 in catalysis.

  11. Solid-state cultivation of Chaetomium cellulolyticum on alkali-pretreated sawdust

    Energy Technology Data Exchange (ETDEWEB)

    Pamment, N; Robinson, C W; Hilton, J; Moo-Young, M

    1978-11-01

    Solid-state fermentations (78% initial moisture content) of alkali-pretreated Eastern Hard Maple sawdust were conducted in tray and tumble fermentors using Chaetomium cellulolyticum. Crude protein content of the solids rose from 0.9 to 11% in the tray fermentor and 8% in the tumble fermentor in 20 days. These levels were almost equal to those achieved in corresponding slurry-state fermentations (1 to 5% (w/v)) of the same substrate. Specific growth rates were two to four times lower in the solid-state fermentors but this was offset by their greater solids-handling capacity: the rate of protein production per unit volume of fermentation mixture was comparable to that of the 5% (w/v) slurry and two to three times higher than that of the 1% (w/v) slurry.

    Summary: This article considers the display of posters as a distinctive activity and defining aspect of British modernism between the two wars, looking to a cardinal event, the Exhibition of British and Foreign Posters at the Victoria and Albert Museum in 1931. This manifestation was the first...... in the Museum to expose the poster-image as a medium in its own artistic, technical, historical and popular right; the article examines the event as a sign holding core characteristics of a ‘poster movement’ prevailing during the interwar years. The period made a varied scene for exhibitions promoting...... commercial and graphic design of various kinds of which British and Foreign Posters offers a particularly rich example. The exhibition attracted commercial, artistic and curatorial forces substantiating the idea of a movement, and approached commercial art from a perspective that raised new awareness towards...

Based on my Ph.D. project on British commercial posters of the interwar years and approached from a combined perspective of museology, semiotics...... and design history, I argue that the poster during the interwar years inhabits a new active position. By exploiting and challenging the commercial and aesthetic paradox out of which it arose, the poster ‘strikes back' as a museologized, exhibited object.

    2017-01-01

    Parallel to the primary functions performed by posters in the urban environment, we find a range of curatorial practices that tie the poster, a mass-produced graphic design media, to the museum institution. Yet little research has attempted to uncover the diverse subject of curatorial work...... and the process where posters created to live in a real-world environment are relocated in a museum. According to Peter Bil’ak (2006), it creates a situation where ”the entire raison d’être of the work is lost as a side effect of losing the context of the work”. The article investigates how environmental...... structures can work as guidelines for curating posters and graphic design in a museum context. By applying an ecological view to design, specifically the semiotic notion “counter-ability”, it stresses the reciprocal relationship of humans and their built and product-designed environments. It further suggests...

    Full Text Available Poster is a communications media that are generally in a large enough format with persuasive and informative messages, pasted on the walls on the roadside and residential alleys. Posters can be so effective in conveying the message as a poster is close to the heart of society. The effectiveness of posters in conveying the message can be seen in the winning poster design of the Smiling Poster Contest 2010. The purpose of this article is to see the effectiveness of communication and poster design in a persuasive smile. A smiling poster is intended to foster and to remind the meaning of a smile in socializing. Concern of poster designers were divided into concern for social problems that occur in society and concern in the development of poster design creativity. Technical and strategic skills are needed by designers of the poster. Since poster design works well, it will eventually become a communicative medium in conveying social messages, becomes the driving motivation in positive, open, creative and inspiring thinking.

    2012-06-01

    Full Text Available The phylogenetic analysis of Clostridium thermocellum family 43 glycoside hydrolase (CtGH43 showed close evolutionary relation with carbohydrate binding family 6 proteins from C. cellulolyticum, C. papyrosolvens, C. cellulyticum, and A. cellulyticum. Comparative modeling of CtGH43 was performed based on crystal structures with PDB IDs 3C7F, 1YIF, 1YRZ, 2EXH and 1WL7. The structure having lowest MODELLER objective function was selected. The three-dimensional structure revealed typical 5-fold beta–propeller architecture. Energy minimization and validation of predicted model with VERIFY 3D indicated acceptability of the proposed atomic structure. The Ramachandran plot analysis by RAMPAGE confirmed that family 43 glycoside hydrolase (CtGH43 contains little or negligible segments of helices. It also showed that out of 301 residues, 267 (89.3% were in most favoured region, 23 (7.7% were in allowed region and 9 (3.0% were in outlier region. IUPred analysis of CtGH43 showed no disordered region. Active site analysis showed presence of two Asp and one Glu, assumed to form a catalytic triad. This study gives us information about three-dimensional structure and reaffirms the fact that it has the similar core 5-fold beta–propeller architecture and so probably has the same inverting mechanism of action with the formation of above mentioned catalytic triad for catalysis of polysaccharides.

The dissemination of these findings is often a difficult final step in a project that has taken months or years to complete. One method of sharing findings in a relaxed and informal setting is a poster presentation. This method is an effective form for presenting findings using an interactive approach. The milieu of a poster presentation enables the presenters to interact and dialogue with colleagues. Guidelines for size and format require that the poster is clear and informative. Application of design helps to create visually appealing posters. This article summarizes elements of designing and conducting a poster presentation.

  10. Kreativitas Desain Poster dalam Kompetisi Desain Poster Nasional

    Full Text Available Poster design competition/contest has become quite often held in Indonesia. Themes and organizers are varied, ranging from educational institutions, government, commercial and social institutions. On the one hand, the rise of this activity can be a trigger for the creativity of the nation, but on the other hand certainly it can cause turmoil in terms of the lack of exploration of ideas and applications. Too much information often overrides the hierarchy of information. Visual elements in a poster design contest overlap, compete for the attention of the viewers, so that we neglect the functions of persuasion. The functions of promotion poster is to communicate everything relating to the contest, including the contest theme, subtheme, explanations and background of the contest, organizers, prizes, attendees can participate, size and amount of work, limitations of work, deadlines, details of the jury, the address and number contest material delivery phone, website or email or phone number the committee can be contacted, and so on. Terms and conditions of the contest should be clearly communicated to the public. Poster contest that contains all of the terms and conditions of the competition will just be a communication medium and severe fatigue with too much text. Promotional poster contest should be able to convey a clear message and information about the contest, as well as be able to inspire and motivate potential competitors, so that the aim to capture ideas and a great poster design can be achieved. For this reason, the poster campaign of the poster competition must appear charming, unique, inspiring, creative, and nuanced in line with the theme.

    2011-01-01

    Poster presentations are commonplace at regional and national nursing conferences, although the development of a poster remains an intimidating task for many staff nurses. The author describes the staff development department's role in implementing in-house poster presentation sessions. Nursing staff are provided support and assistance in presenting posters to their colleagues at yearly sessions. The result has been increased comfort and experience with poster creation, participation in professional development activities, and dissemination of nursing practice innovation.

  16. Look at my poster! Active gaze, preference and memory during a poster session.

    Science.gov (United States)

    Foulsham, Tom; Kingstone, Alan

    2011-01-01

    In science, as in advertising, people often present information on a poster, yet little is known about attention during a poster session. A mobile eye-tracker was used to record participants' gaze during a mock poster session featuring a range of academic psychology posters. Participants spent the most time looking at introductions and conclusions. Larger posters were looked at for longer, as were posters rated more interesting (but not necessarily more aesthetically pleasing). Interestingly, gaze did not correlate with memory for poster details or liking, suggesting that attracting someone towards your poster may not be enough.

    peaks, and river alluvial floodplains. Ecological diversity is remarkably high. There are 7 level III ecoregions and 52 level IV ecoregions in Arizona and many continue into ecologically similar parts of adjacent states. This poster is part of a collaborative project primarily between the U.S. Geological Survey (USGS), USEPA National Health and Environmental Effects Research Laboratory (Corvallis, Oregon), USEPA Region IX, U.S. Department of Agriculture (USDA)–Natural Resources Conservation Service (NRCS), The Nature Conservancy, and several Arizona state agencies. The project is associated with an interagency effort to develop a common national framework of ecological regions. Reaching that objective requires recognition of the differences in the conceptual approaches and mapping methodologies applied to develop the most common ecoregion-type frameworks, including those developed by the USDA–Forest Service, the USEPA, and the NRCS. As each of these frameworks is further refined, their differences are becoming less discernible. Collaborative ecoregion projects, such as this one in Arizona, are a step toward attaining consensus and consistency in ecoregion frameworks for the entire nation.

The author will argue that the use of poster presentations is an ideal opportunity to disseminate research findings and clinical innovations. It offers a new, interesting, and thought-provoking perspective on poster presentations, which includes appraisal of extant literature and reflections about the significance of poster presentations to nursing scholarship. It highlights the benefits of submitting a poster presentation and concludes with some key points for conference reviewers to consider when deciding to select the suitability of abstracts for poster presentations or concurrent sessions.

  7. Proposal to restrict the genus Clostridium Prazmowski to Clostridium butyricum and related species.

    Science.gov (United States)

    Lawson, Paul A; Rainey, Fred A

    2016-02-01

    The genus Clostridium as presently constituted is phylogenetically and phenotypically incoherent. Data from polyphasic taxonomic studies indicate that the genus comprises a collection of very heterogeneous species. Numerous phylogenetic studies, principally based on sequencing of the 16S rRNA gene, indicate that the genus Clostridium should be restricted to Clostridium cluster I as Clostridium sensu stricto . Despite these findings, authors continue to add novel species to the genus Clostridium that do not fall within the radiation of cluster I and the type species Clostridium butyricum , thus perpetuating the confusion associated with the taxonomy of this group. Here, we formally propose that members of the genus Clostridium Prazmowski be restricted to the type species C. butyricum and cluster I species. Eubacterium moniliforme , Eubacterium tarantellae , Sarcina maxima and Sarcina ventriculi should be transferred to the genus Clostridium as Clostridium moniliforme comb. nov., Clostridium tarantellae comb. nov., Clostridium maximum comb. nov. and Clostridium ventriculi comb. nov. A novel genus, Hathewaya gen. nov., is proposed for the species Clostridium histolyticum , Clostridium limosum and Clostridium proteolyticum as Hathewaya histolytica gen. nov. comb. nov., Hathewaya limosa comb. nov. and Hathewaya proteolytica comb. nov. The type species of the genus Hathewaya is Hathewaya histolytica.

    Scientific and educational poster presentations in national and international meetings are one of the most effective means of scientific communication. Poster presentations are of particular importance in a mainly visual speciality like radiology, and also play a significant role in continuing medical education in our specialty. However, poster should be no more than an intermediate step on the way to publish our work in a scientific journal. The publication rates of posters prented in courses and conferences is very low in our country. Therefore, we must continue to progress in training in scientific publication, with efforts such as this supplement. This article review how to create an effective poster presentation.

  1. Hand hygiene posters: motivators or mixed messages?

    Science.gov (United States)

    Jenner, E A; Jones, F; Fletcher, B C; Miller, L; Scott, G M

    2005-07-01

    Poster campaigns regarding hand hygiene are commonly used by infection control teams to improve practice, yet little is known of the extent to which they are based on established theory or research. This study reports on the content analysis of hand hygiene posters (N=69) and their messages (N=75) using message-framing theory. The results showed that posters seldom drew on knowledge about effective ways to frame messages. Frequently, they simply conveyed information 'telling' rather than 'selling' and some of this was confusing. Most posters were not designed to motivate, and some conveyed mixed messages. Few used fear appeals. Hand hygiene posters could have a greater impact if principles of message framing were utilized in their design. Suggestions for gain-framed messages are offered, but these need to be tested empirically.

    2011-12-01

    Despite a decline in popularity within U.S. society, posters continue to hold a prominent place within middle and high school science classrooms. Teachers' demand for posters is largely satisfied by governmental and non-profit science organizations' education and public outreach (EPO) efforts. Here, posters are produced and disseminated as both tangible products resulting from the organization's research, and instruments to communicate scientific content to teachers and students. This study investigates the taken-for-granted good of posters through a survey/interview of science teachers who received sample posters at professional development workshops. The design of sample EPO posters were also examined for their implied, underlying assumptions about learning and their alignment to the setting of the classroom, which is unique for the genera of posters. Based on this analysis we found that rates of poster use were as low as 43% and that many EPO posters fail to achieve their potential as an instructional instrument. As a result, many EPO posters are relegated to merely a collection of pretty pictures on the wall. Leveraging existing research in both cognition and the cognitive theory of Multimedia learning, we propose a design framework for educational posters that is likely to activate students' attention, catalyze cognitive processing, provide a framework to guide students' construction of knowledge, and connect to extended learning through live or web-based exploration of phenomenon. While work to examine the implications of this framework is still on-going, we present a prototype poster and supporting website developed using the framework as a guide, as well as results from focus group discussions with classroom practitioners regarding the prototype poster and its potential in the classroom.

    Receiving a letter confirming acceptance for you to present a poster at a conference can evoke mixed emotions. Joy, panic, fear and dread are among the many possible emotions and this is not exclusive to first time presenters. Developing an effective poster presentation is a skill that you can learn and can provide a rewarding way to present your work in a manner less intimidating than oral presentation (Shelledy, 2004). The key to successful poster presentation is meticulous, timely, well informed preparation. This article outlines ten steps to help guide you through the process to maximize your success.

    Full Text Available An animated film will end in vain no matter how well it is without the support of media to give buzz to the message of the film. One of the most important advertising media in promoting an animated film is the poster. Because the animation movie poster is the leading medium which deals directly with the target audience in delivering information about the film before the screening of the film takes place. So visualization of the poster that includes the composition of verbal and non verbal language deserves more attention in its design.

    Originally pasted on walls and on locations reserved specially for that purpose, the poster is a medium for advertising and promotion to be seen on the streets and in public places. More recently, it has spread, in a smaller format, on dedicated indoor sites: billboards, columns, street furniture, and so forth. For transfusion, it appeared early on that the poster constitutes an important medium to promote blood donation. Thousands of posters supporting regional, national, or international blood donation campaigns have been created all over the planet, with a great variability of images, symbols, and slogans, which are particularly revealing about the image and the reality of blood donation. The topic is rich in information, particularly sociologic, on the variety of ways in which transfusion organizations promote blood donation. The authors present in this article the results of a study based on a total of 283 posters from nations on every continent, divided into 24 different themes. © 2011 American Association of Blood Banks.

    2016-01-01

    Publications and presentations are important in academic medicine. The ability to present information in a standard fashion is critically important. Papers, posters, and slides must be prepared appropriately to maximize their chance of being accepted. The first step is to use word processing software correctly. English language usage must conform to standard scientific English usage. Abbreviations should be avoided as much as possible. Numerical data must be presented with the appropriate number of significant figures. The first step in preparing a paper is to decide the target journal. Papers should always be written in 12 point Times New Roman font, while slides and posters should be in Arial or Helvetica. The Results section must contain actual data with appropriate statistical analysis. Take great care to prepare figures and tables according to the journal's instructions. Posters must be prepared to allow easy reading at a distance of 2m. Use a white background and dark letters. The majority of the area of your poster should be Results, and there is no need to include the abstract or references on a poster. Slide presentations should be limited to about one slide for each minute of the talk. Avoid the use of animations and excessive use of color. Do not use abbreviations on slides. Following these simple guidelines will meet the requirements of most journals and allow your audience to appreciate the data on your posters and slides.

    2010-06-01

    Although sun awareness posters have been used in doctors' offices and clinics for decades to promote sun protective behaviour, there is no evidence of their usefulness. To investigate whether sun awareness posters lead to inquiry of skin cancer and sun protection measures. Patients considered at risk for skin cancer seen at a dermatology clinic were randomly asked to complete a questionnaire designed to assess the effectiveness of three different sun awareness posters placed in patient rooms. The posters were selected on the basis of their catchy slogan and eye-appealing images, and included those featuring parental interest, sex appeal and informative advice. Only half of the patients noticed the posters (50.6%). The poster with sex appeal garnered the most attention (67.8%), followed by the informative poster (49.2%) and the parental interest poster (35.8%) (P poster inquired about cutaneous cancers and sun protection practices twice as often as those who did not notice the poster, only one-tenth of such inquiries were attributed to the poster ( approximately 5% of the target population). As reported in the questionnaire, the posters themselves were less effective than the advice of physicians in influencing patient attitudes towards sun protection measures. Organizations that produce and disseminate posters should consider beyond focus groups when they design their posters and should consider field testing their products to ensure that they are reaching the targeted audience and are having the expected beneficial effect, otherwise their posters are simply decorative.

    2001-05-01

    Dissemination of research findings and effective clinical innovations is key to the growth and development of the nursing profession. Several avenues exist for the dissemination of information. One forum for communication that has gained increased recognition over the past decade is the poster presentation. Poster presentations are often a significant part of regional, national, and international nursing conferences. Although posters are frequently used to disseminate information to the nursing community, little is reported about actual poster presenters' experiences with preparation and presentation of their posters. The purpose of this article is to present insights derived from information shared by poster presenters regarding the poster preparation and presentation process. Such insights derived from the personal experiences of poster presenters may assist others to efficiently and effectively prepare and present scholarly posters that disseminate information to the nursing community.

    The number of posters put up at CERN to inform, engage and invite is growing quickly, and they are taking over an ever-increasing number of walls, doors, pillars and glass panels. In the interests of freedom of information, no official restrictions are in place, but we are nonetheless obliged to maintain a fair balance. Here we discuss this issue.   Posters clamour for our attention, becoming more and more invasive and often eternal as they are never taken down... While the need to inform and to be informed is a legitimate one, we also have to respect our workplace. It’s no surprise that walls or pillars (sometimes freshly painted) at junctions in corridors that are busy at peak times are seen as ideal targets by people who want to publicise their events or activities, but this abundance, or overabundance, of posters is sometimes seen as vandalism of communal areas. What's more, the posters themselves are sometimes vandalised: comments, sometimes offensive, may be added and the...

  5. Comparative pathogenomics of Clostridium tetani.

    Directory of Open Access Journals (Sweden)

    Jonathan E Cohen

    Full Text Available Clostridium tetani and Clostridium botulinum produce two of the most potent neurotoxins known, tetanus neurotoxin and botulinum neurotoxin, respectively. Extensive biochemical and genetic investigation has been devoted to identifying and characterizing various C. botulinum strains. Less effort has been focused on studying C. tetani likely because recently sequenced strains of C. tetani show much less genetic diversity than C. botulinum strains and because widespread vaccination efforts have reduced the public health threat from tetanus. Our aim was to acquire genomic data on the U.S. vaccine strain of C. tetani to better understand its genetic relationship to previously published genomic data from European vaccine strains. We performed high throughput genomic sequence analysis on two wild-type and two vaccine C. tetani strains. Comparative genomic analysis was performed using these and previously published genomic data for seven other C. tetani strains. Our analysis focused on single nucleotide polymorphisms (SNP and four distinct constituents of the mobile genome (mobilome: a hypervariable flagellar glycosylation island region, five conserved bacteriophage insertion regions, variations in three CRISPR (clustered regularly interspaced short palindromic repeats-Cas (CRISPR-associated systems, and a single plasmid. Intact type IA and IB CRISPR/Cas systems were within 10 of 11 strains. A type IIIA CRISPR/Cas system was present in two strains. Phage infection histories derived from CRISPR-Cas sequences indicate C. tetani encounters phages common among commensal gut bacteria and soil-borne organisms consistent with C. tetani distribution in nature. All vaccine strains form a clade distinct from currently sequenced wild type strains when considering variations in these mobile elements. SNP, flagellar glycosylation island, prophage content and CRISPR/Cas phylogenic histories provide tentative evidence suggesting vaccine and wild type strains share a

Our analysis focused on single nucleotide polymorphisms (SNP) and four distinct constituents of the mobile genome (mobilome): a hypervariable flagellar glycosylation island region, five conserved bacteriophage insertion regions, variations in three CRISPR (clustered regularly interspaced short palindromic repeats)-Cas (CRISPR-associated) systems, and a single plasmid. Intact type IA and IB CRISPR/Cas systems were within 10 of 11 strains. A type IIIA CRISPR/Cas system was present in two strains. Phage infection histories derived from CRISPR-Cas sequences indicate C. tetani encounters phages common among commensal gut bacteria and soil-borne organisms consistent with C. tetani distribution in nature. All vaccine strains form a clade distinct from currently sequenced wild type strains when considering variations in these mobile elements. SNP, flagellar glycosylation island, prophage content and CRISPR/Cas phylogenic histories provide tentative evidence suggesting vaccine and wild type strains share a common ancestor.

    Jenner, E A; Jones, F; Fletcher, B C; Miller, L; Scott, G M

    2005-02-01

    This literature review was undertaken to determine the established theory and research that might be utilized to inform the construction of persuasive messages on hand hygiene posters. It discusses the principles of message framing and the use of fear appeals. Current theory suggests that the most effective messages for health promotion behaviours should be framed in terms of gains rather than losses for the individual. However, as clinical hand hygiene is largely for the benefit of others (i.e. patients), messages should also invoke a sense of personal responsibility and appeal to altruistic behaviour. The use of repeated minimal fear appeals have their place. Posters that simply convey training messages are not effective persuaders.

    Clostridium bacteria are anaerobic Gram positive spore-form-ing bacilli, known to cause distinct clinical syndromes such as botulism, tetanus, pseudomembranous colitis and myonecrosis. The natural habitats of Clostridium species are soil, water and the gastrointestinal tract of animals and humans....... In 5-10% of all women, Clostridium species are also found to be normal inhabitants in the microbial flora of the female genital tract. In case of a non-sexually transmitted genital tract infection, Clostridium species are isolated in 4-20%, and clostridium welchii seems to be the most common isolate....... Clostridium sordellii is rarely encountered in clinical specimens (1% of Clostridium species), but it has been described as a human pathogen with fatal potential. Two toxins, a lethal and a hemorrhagic (that antigenically and pathophysiologically appear similar to Clostridium difficile toxins B and A...

    W. E. Morris

    2009-12-01

    Full Text Available Clostridium perfringens es un bacilo grampositivo anaerobio con capacidad de formar esporas. Es uno de los patógenos bacterianos con mayor distribución en el medio ambiente, ya que puede ser aislado de muestras de suelo y de agua y además forma parte de la microbiota intestinal de animales y humanos. Sin embargo, en ciertas ocasiones puede actuar como patógeno oportunista y causar enfermedades como la gangrena gaseosa, la enterotoxemia del ovino y del caprino y la disentería del cordero, entre otras. En humanos, está asociado a enfermedades como la intoxicación por alimentos, la enterocolitis necrotizante en niños y la enteritis necrótica o pigbel de las tribus de Papúa-Nueva Guinea. El renovado interés que existe actualmente en el estudio de C. perfringens como patógeno veterinario y humano, junto con el avance de la biología molecular, han hecho posible que la ciencia tenga hoy un conocimiento más profundo sobre la biología y la patogenia de esta bacteria. En esta revisión bibliográfica se discuten y actualizan los principales aspectos de la patogenia intestinal de C. perfringens teniendo en cuenta las toxinas con mayor importancia médica descritas hasta el presente.Clostridium perfringens is an anaerobic gram-positive spore-forming bacillus. It is one of the pathogens with larger distribution in the environment; it can be isolated from soil and water samples, which also belongs to the intestinal flora of animals and humans. However, on some occasions it can act as an opportunistic pathogen, causing diseases such as gas gangrene, enterotoxemia in sheep and goats and lamb dysentery, among others. In human beings, it is associated to diseases such as food poisoning, necrotic enterocolitis of the infant and necrotic enteritis or pigbel in Papua-New Guinea tribes. The renewed interest existing nowadays in the study of C. perfringens as a veterinarian and human pathogen, together with the advance of molecular biology, had enabled

  16. Poster power brings together electronics community

    CERN Multimedia

    2006-01-01

    An 'Electronics at CERN' poster session was displayed on the mezzanine in building 500 for two days from 30 November. The display consisted of 20 posters and brought together a wide range of electronic projects designed and assembled by CERN teams and other collaborators involved in the building of the LHC. This was the first time this event had been held. As its organiser John Evans (IT/DES) explained, 'the idea came from the experience of attending conferences outside CERN, where you may find projects from CERN you didn't know about. It's nice to bring them together so we can all benefit from the efforts made.' The work on show spanned different departments and experiments, ranging from microelectronics to equipment designed for giant magnets. The invited audience was equally broad and included engineers, physicists as well as the electronics community at CERN. An informal gathering of all the exhibitors also offered an opportunity to view and discuss the work over a cup of coffee. 'The poster session acts...

    Literature exploring the educational value and quality of conference poster presentation is scarce. The aim of this study was to identify and describe the variation in poster exhibitions across a spectrum of conferences attended by trainees. Prospective observational assessment of conference posters was carried out across 7 variables at 4 conferences attended by surgical trainees in 2012. Posters were compared by individual variables and according to overall poster score combining all 7 variables examined. The number of authors listed was also compared. Random samples of consecutively numbered posters were examined at the exhibitions of 4 conferences, which included a UK national medical education conference (Association for the Study of Medical Education), a UK international surgical conference (Association of Surgeons of Great Britain and Ireland), a European oncology conference (European Society of Surgical Oncology), and a North American joint medical and surgical conference (Digestive Diseases Week). Significant variation existed between conferences in posters and their presentation. The proportion of presenters failing to display their posters ranged from 3% to 26% (p posters that were formatted using aims, methods, results, and conclusion sections (81%-93%; p = 0.513) or in the proportion of posters that were identified as difficult to read (24%-28%; p = 0.919). Association for the Study of Medical Education outperformed each of the other exhibitions overall (p Posters with greater than the median of 4 authors performed significantly better across all areas (p Poster exhibitions varied widely, with room for improvement at all 4 conferences. Lessons can be learned by all conferences from each other to improve presenter engagement with and the educational value of poster exhibitions.

  18. Polyclonal Antibody Therapies for Clostridium difficile Infection

    Directory of Open Access Journals (Sweden)

    Michael R. Simon

    2014-10-01

    Full Text Available Clostridium difficile infection has emerged as a growing worldwide health problem. The colitis of Clostridium difficile infection results from the synergistic action of C. difficile secreted toxins A and B upon the colon mucosa. A human monoclonal IgG anti-toxin has demonstrated the ability in combination therapy to reduce mortality in C. difficile challenged hamsters. This antibody is currently in a clinical trial for the treatment of human Clostridium difficile infection. More than one group of investigators has considered using polyclonal bovine colostral antibodies to toxins A and B as an oral passive immunization. A significant proportion of the healthy human population possesses polyclonal antibodies to the Clostridium difficile toxins. We have demonstrated that polyclonal IgA derived from the pooled plasma of healthy donors possesses specificity to toxins A and B and can neutralize these toxins in a cell-based assay. This suggests that secretory IgA prepared from such pooled plasma IgA may be able to be used as an oral treatment for Clostridium difficile infection.

  19. Update on Clostridium difficile infections.

    2014-08-01

    Clostridium difficile infections (CDI) occur primarily in hospitalized patients with risk factors such as concomitant or recent use of antibiotics. CDI related additional costs are important for the global population and health-care facilities. CDI epidemiology has changed since 2003: they became more frequent boosted by large outbreaks, more severe, more resistant to antibiotic treatment, and spread to new groups of population without any risk factor. This is partly due to the emergence and worldwide dissemination of new and more virulent C. difficile strains such as the epidemic clone 027/NAP1/BI. The host immune response plays a central role in the pathogenesis of CDI and could also be involved in the occurrence of recurrent or severe forms. New guidelines including new molecular tests (NAAT) have recently clarified and simplified the diagnostic strategies for the microbiological diagnosis of CDI. The CDI incidence was proven to be related to the level of clinical suspicion and the frequency of microbiological screening for C. difficile. The current recommendations for the treatment of CDI mention oral metronidazole as the first line treatment for mild to moderate diarrhea. Oral vancomycin use should be restricted to severe cases. In the absence of consensus, the treatment of multiple recurrences remains a major concern. New and more targeted antibiotics and innovative therapeutic strategies (fecal transplantation, monoclonal antibodies, and vaccination) have emerged as new therapies for CDI.

  20. Epidemiology of Clostridium difficile Infection

    Science.gov (United States)

    DePestel, Daryl D.; Aronoff, David M.

    2014-01-01

    There has been dramatic change in the epidemiology of Clostridium difficile infection (CDI) since the turn of the 21st Century noted by a marked increase in incidence and severity, occurring at a disproportionately higher frequency in older patients. Historically considered a nosocomial infection associated with antibiotic exposure, CDI has now also emerged in the community in populations previously considered low risk. Emerging risk factors and disease recurrence represent continued challenges in the management of CDI. The increased incidence and severity associated with CDI has coincided with the emergence and rapid spread of a previously rare strain, ribotype 027. Recent data from the U.S. and Europe suggest the incidence of CDI may have reached a crescendo in recent years and is perhaps beginning to plateau. The acute-care direct costs of CDI were estimated to be $4.8 billion in 2008. However, nearly all the published studies have focused on CDI diagnosed and treated in acute-care hospital setting and fail to measure the burden outside the hospital, including recently discharged patients, outpatients, and those in long-term care facilities. Enhanced surveillance methods are needed to monitor the incidence, identify populations at risk, and characterize the molecular epidemiology of strains causing CDI. PMID:24064435

    Berg, Judith; Hicks, Rod

    2017-08-01

    Poster presentations are increasingly popular for dissemination of scientific and clinical knowledge at professional meetings; however, this professional skill is generally absent from advanced practice registered nurse (APRN) curricula and acquisition of the skill must occur in other arenas. The purpose of this article is to promote professional development by educating APRNs, students, and faculty on the essentials of poster development and presentation. To aid in poster presentation skill development, types of posters, advantages and disadvantages, content and design, and tips to enhance these presentations are discussed. What is known on these topics is summarized and emphasis on professional appearance and conduct is highlighted. Content and layout, use of color, imagery, and positive and negative space are crucial design elements. Poster presentation essentials include being prepared, professional appearance, and professional behavior. Designing and presenting a professional poster is an essential skill for all APRNs as the ability to communicate knowledge is central to the role. ©2017 American Association of Nurse Practitioners.

    Illuminating type poster looks very impressive and one may feel as if it were on the view box in his reading room. Some difficulties and nuisances really exist in making them and a few of demerits can also be encountered that of contrast enhancement and of rough graininess. Contact print renders the best quality, though, Kodak Technical-Pan film with HC-100 (Dil. F) developer, llford XP 1-400 with Kodak C-41 color developer and Kodak Plus-X with Microdiol-X developer combinations also work in minimizing the deterioration of resolution and grains which can almost always occur in enlargement prints.

    The pathogenic bacteria Clostridium difficile, Clostridium perfringens and Clostridium botulinum produce the binary actin ADP-ribosylating toxins CDT, iota and C2, respectively. These toxins are composed of a transport component (B) and a separate enzyme component (A). When both components assemble on the surface of mammalian target cells, the B components mediate the entry of the A components via endosomes into the cytosol. Here, the A components ADP-ribosylate G-actin, resulting in depolymerization of F-actin, cell-rounding and eventually death. In the present study, we demonstrate that 4-bromobenzaldehyde N-(2,6-dimethylphenyl)semicarbazone (EGA), a compound that protects cells from multiple toxins and viruses, also protects different mammalian epithelial cells from all three binary actin ADP-ribosylating toxins. In contrast, EGA did not inhibit the intoxication of cells with Clostridium difficile toxins A and B, indicating a possible different entry route for this toxin. EGA does not affect either the binding of the C2 toxin to the cells surface or the enzyme activity of the A components of CDT, iota and C2, suggesting that this compound interferes with cellular uptake of the toxins. Moreover, for C2 toxin, we demonstrated that EGA inhibits the pH-dependent transport of the A component across cell membranes. EGA is not cytotoxic, and therefore, we propose it as a lead compound for the development of novel pharmacological inhibitors against clostridial binary actin ADP-ribosylating toxins.

    Flagellins from Clostridium botulinum were shown to be post-translationally modified with novel glycan moieties by top-down MS analysis of purified flagellin protein from strains of various toxin serotypes. Detailed analyses of flagellin from two strains of C. botulinum demonstrated that the protein is modified by a novel glycan moiety of mass 417 Da in O-linkage. Bioinformatic analysis of available C. botulinum genomes identified a flagellar glycosylation island containing homologs of genes recently identified in Campylobacter coli that have been shown to be responsible for the biosynthesis of legionaminic acid derivatives. Structural characterization of the carbohydrate moiety was completed utilizing both MS and NMR spectroscopy, and it was shown to be a novel legionaminic acid derivative, 7-acetamido-5-(N-methyl-glutam-4-yl)-amino-3,5,7,9-tetradeoxy-D-glycero-alpha-D-galacto-nonulosonic acid, (alphaLeg5GluNMe7Ac). Electron transfer dissociation MS with and without collision-activated dissociation was utilized to map seven sites of O-linked glycosylation, eliminating the need for chemical derivatization of tryptic peptides prior to analysis. Marker ions for novel glycans, as well as a unique C-terminal flagellin peptide marker ion, were identified in a top-down analysis of the intact protein. These ions have the potential for use in for rapid detection and discrimination of C. botulinum cells, indicating botulinum neurotoxin contamination. This is the first report of glycosylation of Gram-positive flagellar proteins by the 'sialic acid-like' nonulosonate sugar, legionaminic acid.

    Clostridium difficile is the aetiological agent in ca. 20% of cases of antimicrobial-associated diarrhoea in hospitalised adults. Diseases caused by this organism range from mild diarrhoea to occasional fatal pseudomembranous colitis. The epidemiology of C. difficile infection (CDI) has changed notably in the past decade, following epidemics in the early 2000s of PCR ribotype (RT) 027 infection in North America and Europe, where there was an increase in disease severity and mortality. Another major event has been the emergence of RT 078, initially as the predominant ribotype in production animals in the USA and Europe, and then in humans in Europe. Although there have been numerous investigations of the epidemiology of CDI in North America and Europe, limited studies have been undertaken elsewhere, particularly in Asia. Antimicrobial exposure remains the major risk factor for CDI. Given the high prevalence of indiscriminate and inappropriate use of antimicrobials in Asia, it is conceivable that CDI is relatively common among humans and animals. This review describes the level of knowledge in Thailand regarding C. difficile detection methods, prevalence and antimicrobial susceptibility profile, as well as the clinical features of, treatment options for and outcomes of the disease. In addition, antimicrobial usage in livestock in Thailand will be reviewed. A literature search yielded 18 studies mentioning C. difficile in Thailand, a greater number than from any other Asian country. It is possible that the situation in Thailand in relation to CDI may mirror the situation in other developing Asians countries.

    Full Text Available If the great Constantin Stanislavski said that the theatre starts from the cloak-room, today, in the era of broadcasting, we could reformulate the idea, confi rming that the theatre starts with the poster. Posters in the modern variant appeared with the emergence of the printing press. J. Gutenberg’s invention in 1453 became the beginning of the third information revolution, signifying a new stage in the evolution of commercials. Th e poster tradition has taken a new momentum in the nineteenth century. Let us remember such masters as the famous French painter Henri de Toulouse-Lautrec and the Czech Alphonse Mucha (who became popular thanks to the posters with Sarah Bernhardt, and who laid the foundation of the principles of the European theatre poster. The analysis of theatre posters from the Republic of Moldova, certifi es their evolution from text information to the artistic-aesthetic image, from the purely informative image to the suggestive-symbolic one. To exemplify these ideas, we will use posters created for the shows of the „Licurici” and „Guguţă” Puppet Th eatres. Th e authors’ purpose was to present in the foreground of the show the title and the main characters keeping the same style that arouses the attention and curiosity of children. The posters, that promote the meanings and symbols of the message, are increasingly required. So, in a symbolic key, are made the posters for the plays „Swan Flight” (by Andersen, „Făt-Frumos din lacrimă” (by Mihai Eminescu, directed by Nina Zabrodin; „Planeta de rouă” (by Grigore Vieru, directed by Ion Puiu, „Cămașa norocului”, directed by Tatiana Cojocaru etc. Currently the poster (theatre poster has become an art form and submits peculiar artistic regularities and peculiarities, requiring not only a high artistic level of achievement, but also a conceptual one.

  20. A new technique for presentation of scientific works: video in poster.

    Science.gov (United States)

    Bozdag, Ali Dogan

    2008-07-01

    Presentations at scientific congresses and symposiums can be in two different forms: poster or oral presentation. Each method has some advantages and disadvantages. To combine the advantages of oral and poster presentations, a new presentation type was conceived: "video in poster." The top of the portable digital video display (DVD) player is opened 180 degrees to keep the screen and the body of the DVD player in the same plane. The poster is attached to the DVD player and a window is made in the poster to expose the screen of the DVD player so the screen appears as a picture on the poster. Then this video in poster is fixed to the panel. When the DVD player is turned on, the video presentation of the surgical procedure starts. Several posters were presented at different medical congresses in 2007 using the "video in poster" technique, and they received poster awards. The video in poster combines the advantages of both oral and poster presentations.

    2014-01-01

    Presenting an abstract and a poster gives scientists from all fields, including psychiatry, an important opportunity to introduce their research to others. Researchers and mental health professionals at all levels of career development can use several media resources to assist them with the technical aspects of preparing an abstract or a poster. This article will focus on major principles associated with preparing and presenting an abstract and a poster at a scientific meeting. A literature search using NIH PubMed was conducted to identify peer and non-peer-reviewed articles that provide methods for effective abstract and poster presentation for the period of 1966 to June 2014. First, we review the purpose and relative importance of abstracts and posters in academic settings. Next, we describe the qualities of an effective abstract and poster and common pitfalls that may occur. Finally, we present a systematic approach to preparing and presenting an abstract and a poster in a scientific setting. Several sources consistently suggest that readability, organization, and succinctness are qualities that make an effective and successful abstract and poster. Mental health professionals in all stages of their career development may benefit from following these guidelines in presenting their scientific work. PMID:25085499

  3. Tracing the 'grey literature' of poster presentations: a mapping review.

    2017-04-06

    Posters are a popular way of presenting information at conferences. However, little research has been conducted into their development, and the patterns and extent of their use are unclear. A mapping review was performed to chart the development and utilisation of the poster medium, and to highlight the main literature themes and contributions. A search for the term 'poster presentation' was conducted simultaneously in 249 databases. Results were categorised by discipline and analysed by decade. The results were used to form an informetric-based mapping review. (i) Medicine and health care disciplines are the predominant poster users and since 1990 have accounted for 68-75% of the overall published data. (ii) Over 99% of the returns led only to abstract or title citations for conference posters. (iii) Poster presentations offer much potentially useful information, but remain difficult to access. If the aim of poster presentation is to share and discuss information with others, then the limitations of poster abstracts and questions raised in the retrieved literature suggest that further efforts are required to make this more effective. Library and information specialists of all disciplines are likely to play a key role in such developments, and especially those from the medicine and health care disciplines which feature so prominently. © 2017 Health Libraries Group.

    Presenting posters at national meetings can help fellows and junior faculty members develop a national reputation. They often lead to interesting and fruitful networking and collaboration opportunities. They also help with promotion in academic medicine and can reveal new job opportunities. Practically, presenting posters can help justify funding to attend a meeting. Finally, this process can be invaluable in assisting with manuscript preparation. This article provides suggestions and words of wisdom for palliative care fellows and junior faculty members wanting to present a poster at a national meeting describing a case study or original research. It outlines how to pick a topic, decide on collaborators, and choose a meeting for the submission. It also describes how to write the abstract using examples that present a general format as well as writing tips for each section. It then describes how to prepare the poster and do the presentation. Sample poster formats are provided as are talking points to help the reader productively interact with those that visit the poster. Finally, tips are given regarding what to do after the meeting. The article seeks to not only describe the basic steps of this entire process, but also to highlight the hidden curriculum behind the successful abstracts and posters. These tricks of the trade can help the submission stand out and will make sure the reader gets the most out of the hard work that goes into a poster presentation at a national meeting.

    2016-12-01

    The Virtual Poster Showcase (VPS), now in its second year of implementation, has garnered a lot of interest from the geoscience community. The platform enables both undergraduate and graduate students to present their research from anywhere in the world without having to travel to a national or international conference. The VPS platform is simple to use and consists of three steps which include submission of an abstract, uploading a poster and a short video presentation explaining the work, and judging three peer posters online and receiving feedback/comments on their own posters. Based on the completed showcases from 2015 and now 2016, students reported gains in confidence in both preparing and presenting research posters as well as the impact on their careers based on post-showcase evaluations. This presentation will discuss some statistics about the showcases and participants, student evaluation results, stories and anecdotes about the showcases impact on individual students and faculty, as well as plans for the coming year.

  12. Poster presentation - a visual medium for academic and scientific meetings.

    Rowe, Nicholas; Ilic, Dragan

    2011-09-01

    Academic poster presentations are used as a medium of knowledge transfer by a wide range of health professional groups. Posters also provide a means of publication for academic and professional contributors. Posters are designed to give a visual representation of an issue that firstly attracts attention, and then conveys an intended message. Whilst the poster medium has become adopted into the publication orthodoxy of the scientific and academic communities, there are acknowledged limitations regarding the depth of knowledge transfer, issues of compilation and production, and the related viewer conception. If treated as a standalone medium, the limitations of a two-dimensional, page limited format may not provide the ideal opportunity to deliver the depth of information required within the academic context. Despite these limitations however, the continued use of posters is justified when supported by author presentation or multi-media resources. This paper aims to provide an overview of the current concept and practicality of academic poster publications. It also outlines by example, some of the wider principles of poster compilation and presentation, for use by those who may utilise the medium at academic and scientific meetings.

    Full Text Available Clostridium difficile is a Gram-positive, spore-forming, anaerobic bacillus that is widely distributed in the environment, but is found as a part of a normal large bowel flora in approximately 3% of normal adults. C. difficile produces two protein exotoxins: toxin A and toxin B. Both toxins are responsible for causing the sings and symptoms of disease.C. difficile is now thought to be responsible for a spectrum of diseases, ranging from asymptomatic colonization to diarrhea of varying severity, life-threatening colitis, often as a consequence of long-term antibiotic exposure. This spectrum has become known as C. difficile-associated disease (CDAD.Treatment of Clostridium difficile-associated disease demand administration of effi-cient antibiotics (vancomycin, metronidazole, anion exchange resins and probiotics (Lactobacillus spp., Saccharomyces boulardii.

    To implement and assess a required public health poster project in a doctor of pharmacy (PharmD) program. Third-year PharmD students collaborated in pairs to research a public health topic relating to pharmacy practice. Each student group prepared an informational poster, while receiving feedback from a faculty mentor at each stage of the project. The students presented their completed posters at a statewide pharmacy conference. Faculty members evaluated the posters with a grading rubric, and students completed a survey instrument that assessed the overall experience. In general, faculty members rated the class highly across all domains of the grading rubric. The class generally agreed that the poster project increased their awareness of public health issues related to pharmacy practice, overall knowledge of public health, and presentation skills. The implementation of a poster project was well received by students and faculty members as an effective method for enhancing public health instruction in the PharmD program at North Dakota State University.

  10. Plasmidome interchange between Clostridium botulinum, Clostridium novyi and Clostridium haemolyticum converts strains of independent lineages into distinctly different pathogens.

    Skarin, Hanna; Segerman, Bo

    2014-01-01

    Clostridium botulinum (group III), Clostridium novyi and Clostridium haemolyticum are well-known pathogens causing animal botulism, gas gangrene/black disease, and bacillary hemoglobinuria, respectively. A close genetic relationship exists between the species, which has resulted in the collective term C. novyi sensu lato. The pathogenic traits in these species, e.g., the botulinum neurotoxin and the novyi alpha toxin, are mainly linked to a large plasmidome consisting of plasmids and circular prophages. The plasmidome of C. novyi sensu lato has so far been poorly characterized. In this study we explored the genomic relationship of a wide range of strains of C. novyi sensu lato with a special focus on the dynamics of the plasmidome. Twenty-four genomes were sequenced from strains selected to represent as much as possible the genetic diversity in C. novyi sensu lato. Sixty-one plasmids were identified in these genomes and 28 of them were completed. The genomic comparisons revealed four separate lineages, which did not strictly correlate with the species designations. The plasmids were categorized into 13 different plasmid groups on the basis of their similarity and conservation of plasmid replication or partitioning genes. The plasmid groups, lineages and species were to a large extent entwined because plasmids and toxin genes had moved across the lineage boundaries. This dynamic process appears to be primarily driven by phages. We here present a comprehensive characterization of the complex species group C. novyi sensu lato, explaining the intermixed genetic properties. This study also provides examples how the reorganization of the botulinum toxin and the novyi alpha toxin genes within the plasmidome has affected the pathogenesis of the strains.

    2015-10-01

    After its U.S. FDA approval in 2013, Collagenase Clostridium histolyticum (CCh) has seen increasing use as a nonoperative treatment for Peyronie's disease (PD). We review the history of CCh and trials that led to its adoption. To provide a historical and contemporary context for the evolution of Collagenase Clostridium histolyticum as a treatment modality for Peyronie's disease. A comprehensive search of peer-reviewed literature was performed pertaining to CCh and its biochemical and clinical significance. The main outcome studied was the efficacy and safety profile of CCh in PD. CCh use in other diseases processes and its associated outcomes are also described. CCh injection yields objective improvement in penile curvature across multiple trials in PD patients. Recently, level 1 strength of evidence has emerged supporting its widespread use. As such, CCh stands as the only FDA-approved injectable therapy for PD. Adverse events were namely limited to local reactions. Serious systemic complications and need for intervention were rare. CCh is a safe and effective treatment for PD patients with deformities and plaque configuration amenable to injectable therapy. Multiple trials have demonstrated improvements in objective and subjective metrics such as penile curvature and bother scores. However, multiyear follow-up is needed to assess durability and its sustained clinical significance. Currently, refinement in dosing and technique has established a niche for CCh in PD patients who are affected by their symptoms but are not yet committed to surgical intervention.

    Full Text Available Clostridium difficile is currently the most frequently identified pathogen causing antibiotic-associated diarrhea and the main cause of nosocomial diarrhea. In recent years, increases incidence of infection, severe infection, recurrent infection and mortality from Clostridium difficile infection (CDI have been observed. This may be a consequence of excessive antibiotic use and spread of the hypervirulent epidemic BI/NAP1/027 strain of Clostridium difficile. The main risk factors for CDI are: antibiotic therapy, previous hospitalizations and number of comorbid conditions. Prevention of CDI mainly is focused in two directions: reducing the exposure of patients to the disease pathogen by intensifying hygiene measures, and reducing the impact of risk factors. A meta-analyses of clinical studies (observational, cohort and case control showed significantly higher risk of CDI and CDI recurrence in patients with chronic kidney disease and increased mortality risk in chronic kidney disease patients with CDI comparing those without CDI. Increased risk of CDI in patients with chronic kidney disease can be caused by: frequent antibiotic therapy associated with numerous infections resulting in intestinal microflora dysfunction, frequent hospitalizations, older age of the patients and an impaired immune system. Among preventative measures against CDI, the use of probiotics were also studied. In patients hospitalized in nephrology ward highly significant reduction of the CDI incidence was observed after the introduction of Lactobacillus plantarum 299v as CDI prophylaxis. Therefore, the use of Lactobacillus plantarum 299v seems to be a promising method of CDI prevention in chronic kidney disease patients hospitalized in nephrology ward.

    The role of probiotics as adjunctive measures in the prevention of Clostridium difficile infection (CDI) has been controversial. However, a growing body of evidence has suggested that they have a role in primary prevention of CDI. Elements of this controversy are reviewed and the proposed mechanisms of action, the value and cost effectiveness of probiotics are addressed with a focus on three agents, Saccharomyces boulardii, Lactobacillus rhamnosus GG and the combination of Lactobacillus acidophilus CL1285, Lactobacillus casei LBC80R, Lactobacillus rhamnosus CLR2 (Bio-K+).

  15. Annotation of the Clostridium Acetobutylicum Genome

    Energy Technology Data Exchange (ETDEWEB)

    Daly, M. J.

    2004-06-09

    The genome sequence of the solvent producing bacterium Clostridium acetobutylicum ATCC824, has been determined by the shotgun approach. The genome consists of a 3.94 Mb chromosome and a 192 kb megaplasmid that contains the majority of genes responsible for solvent production. Comparison of C. acetobutylicum to Bacillus subtilis reveals significant local conservation of gene order, which has not been seen in comparisons of other genomes with similar, or, in some cases, closer, phylogenetic proximity. This conservation allows the prediction of many previously undetected operons in both bacteria.

    2013-10-01

    To quantify the risk of death associated with Clostridium difficile infection, in an Australian tertiary hospital. Two reviews examining Clostridium difficile infection and mortality indicate that Clostridium difficile infection is associated with increased mortality in hospitalized patients. Studies investigating the mortality of Clostridium difficile infection in settings outside of Europe and North America are required, so that the epidemiology of Clostridium difficile infection in these regions can be understood and appropriate prevention strategies made. An observational non-concurrent cohort study design was used. Data from all persons who had (exposed) and a matched sample of persons who did not have Clostridium difficile infection, for the calendar years 2007-2010, were analysed. The risk of dying within 30, 60, 90 and 180 days was compared using the two groups. Kaplan-Meier survival analysis and conditional logistic regression models were applied to the data to examine time to death and mortality risk adjusted for comorbidities using the Charlson Comorbidity Index. One hundred and fifty-eight cases of infection were identified. A statistically significant difference in all-cause mortality was identified between exposed and non-exposed groups at 60 and 180 days. In a conditional regression model, mortality in the exposed group was significantly higher at 180 days. In this Australian study, Clostridium difficile infection was associated with increased mortality. In doing so, it highlights the need for nurses to immediately instigate contact precautions for persons suspected of having Clostridium difficile infection and to facilitate a timely faecal collection for testing. Our findings support ongoing surveillance of Clostridium difficile infection and associated prevention and control activities. © 2013 Blackwell Publishing Ltd.

    The pangenome for the genus Clostridium sensu stricto, which was obtained using highly curated and annotated genomes from 16 species is presented; some of these cause disease, while others are used for the production of added-value chemicals. Multilocus sequencing analysis revealed that species of this genus group into at least two clades that include non-pathogenic and pathogenic strains, suggesting that pathogenicity is dispersed across the phylogenetic tree. The core genome of the genus includes 546 protein families, which mainly comprise those involved in protein translation and DNA repair. The GS-GOGAT may represent the central pathway for generating organic nitrogen from inorganic nitrogen sources. Glycerol and glucose metabolism genes are well represented in the core genome together with a set of energy conservation systems. A metabolic network comprising proteins/enzymes, RNAs and metabolites, whose topological structure is a non-random and scale-free network with hierarchically structured modules was built. These modules shed light on the interactions between RNAs, proteins and metabolites, revealing biological features of transcription and translation, cell wall biosynthesis, C1 metabolism and N metabolism. Network analysis identified four nodes that function as hubs and bottlenecks, namely, coenzyme A, HPr kinases, S-adenosylmethionine and the ribonuclease P-protein, suggesting pivotal roles for them in Clostridium. © 2017 Society for Applied Microbiology and John Wiley & Sons Ltd.

    1998-01-01

    A gene, encoding an endocellulase from a newly isolated mesophilic Clostridium strain IY-2 which can digest bamboo fibers, cellulose, rice straw, and sawdust, was isolated by shotgun cloning in an E. coli expression plasmid pLC2833. E. coli positive clones were selected based on their ability to hydrolyze milled bamboo fibers and cellulose present in agar plates. One clone contained a 2.8 kb DNA fragment that was responsible for cellulase activity. Western blot analyses indicated that the positive clone produced a secreted cellulase with a mass of about 58,000 daltons that was identical in size to the subunit of one of the three major Clostridium cellulases. The products of cellulose digestion by this cloned cellulase were cellotetraose and soluble higher polymers. The cloned DNA contained signal sequences capable of directing the secretion of heterologous proteins from an E. coli host. The invention describes a bioprocess for the treatment of cellulosic plant materials to produce cellular growth substrates and fermentation end products suitable for production of liquid fuels, solvents, and acids.

  1. Key Research Issues in Clostridium difficile

    2005-01-01

    Full Text Available Clostridium difficile is an emerging pathogen that causes C difficile-associated diarrhea, an important nosocomial infection. Control of this infection remains a challenge, and much needs to be determined about the antimicrobial resistance of the organism, antibiotic stewardship, contamination of the patient environment, and various host factors that determine susceptibility or resistance to infection. A national symposium focusing on C difficile infections, the Clostridium difficile Symposium on Emerging Issues and Research, was hosted on November 23, 2004, by the Department of Medical Microbiology and Infectious Diseases at the University of Manitoba, Winnipeg, Manitoba, in partnership with the Canadian Institutes of Health Research. This symposium, which aimed to summarize key research issues regarding C difficile infections in Canada, had the following objectives: to provide a forum for learning and discussion about C difficile and its impact on the health of Canadians; to identify the key research issues that should be addressed; and to explore potential research funding opportunities and collaboration. The present report summarizes key research issues identified for C difficile infections in Canada by addressing four major themes: diagnosis and surveillance, infection prevention and control, antibiotic stewardship, and clinical management.

    Full Text Available Poster is a product of graphic prepared for ıntorducing a culture or goods; or tranmitting a message. We can come across a poster almost in anywhere. As a product of graphic, a poster hav found its own place in many art movements and that’s why one should have the same concern for it as for others in the aspects of design and artistic view. The most important target of a commercial or advertisement is to reach the exact target audience at the exact time. Poster from its very begining, has became an area that needs a speciality in appliyng. Poster design aims to leave the neccessary effect whether by introducing the idea/product or by directing the target audience to the idea/ product. It is for sure that while moving the target audience to the aimed idea/ product, it is more easily-remembered using the popular cultural ıbjects which have a profound effect on the target audıence. Popular culture is mass culture. It is aimed to move the massive population by using the popular people, products and etc. In fact popular culture is a society to burden the creatvity and prodcution. It also a reason to resemble the society each other and it is a unit of constant changing. It is a consumption society in another saying. It supports consumption. In poster designs, it can be seen that designs are done under the effect of these popular culture. It is via this poiciy that consumers are directed to the target message or product.

    2015-05-01

    Sporulation is an important strategy for certain bacterial species within the phylum Firmicutes to survive longer periods of time in adverse conditions. All spore-forming bacteria have two phases in their life; the vegetative form, where they can maintain all metabolic activities and replicate to increase numbers, and the spore form, where no metabolic activities exist. Although many essential components of sporulation are conserved among the spore-forming bacteria, there are differences in the regulation and the pathways among different genera, even at the species level. While we have gained much information from the most studied spore-forming bacterial genus, Bacillus, we still lack an in-depth understanding of spore formation in the genus Clostridium. Clostridium and Bacillus share the master regulator of sporulation, Spo0A, and its downstream pathways, but there are differences in the activation of the Spo0A pathway. While Bacillus species use a multi-component phosphorylation pathway for phosphorylation of Spo0A, termed phosphorelay, such a phosphorelay system is absent in Clostridium. On the other hand, a number of genes regulated by the different sporulation-specific transcription factors are conserved between different Clostridium and Bacillus species. In this review, we discuss the recent findings on Clostridium sporulation and compare the sporulation mechanism in Clostridium and Bacillus. Copyright © 2014 Institut Pasteur.

    1981-02-01

    Dipicolinic acid (DPA) synthesis was studied in Clostridium roseum by permitting the organism to complete vegetative growth in trypticase medium and trasfering the cells to a non-growth-promoting-medium, supplemented with the appropriate /sup 14/C-labelled precursors to complete sporulation and assaying the incorporation of label into DPA. Glu, asp, ala, ser and acetate were found to be efficient precursors of DPA and each one influenced the incorporation of other into DPA. The data suggest that a C/sub 5/ precursor is being trasformed into a C/sub 4/ intermediate, and a C/sub 2/ precursor into a C/sub 4/ intermediate, before their entry into DPA carbon structure. A C/sub 4/ plus C/sub 3/ condensation is favoured over C/sub 5/ plus C/sub 2/ or other condensation in the DPA biosynthesis.

    The ability to effectively communicate through posters and podium presentations using appropriate visual content and style is essential for health care educators. To offer suggestions for more effective visual elements of posters and podium presentations. We present the experiences of our multidisciplinary publishing group, whose combined experiences and collaboration have provided us with an understanding of what works and how to achieve success when working on presentations and posters. Many others would offer similar advice, as these guidelines are consistent with effective presentation. FINDINGS/SUGGESTIONS: Certain visual elements should be attended to in any visual presentation: consistency, alignment, contrast and repetition. Presentations should be consistent in font size and type, line spacing, alignment of graphics and text, and size of graphics. All elements should be aligned with at least one other element. Contrasting light background with dark text (and vice versa) helps an audience read the text more easily. Standardized formatting lets viewers know when they are looking at similar things (tables, headings, etc.). Using a minimal number of colors (four at most) helps the audience more easily read text. For podium presentations, have one slide for each minute allotted for speaking. The speaker is also a visual element; one should not allow the audience's view of either the presentation or presenter to be blocked. Making eye contact with the audience also keeps them visually engaged. Health care educators often share information through posters and podium presentations. These tips should help the visual elements of presentations be more effective.

    2011-04-01

    This study aimed to ascertain the value of posters at medical meetings to presenters and delegates. The usefulness of posters to presenters at national and international meetings was evaluated by assessing the numbers of delegates visiting them and the reasons why they visited. Memorability of selected posters was assessed and factors influencing their appeal to expert delegates identified. At both the national and international meetings, very few delegates (posters. Only a minority read them and fewer asked useful questions. Recall of content was so poor that it prevented identification of factors improving their memorability. Factors increasing posters' visual appeal included their scientific content, pictures/graphs and limited use of words. Few delegates visit posters and those doing so recall little of their content. To engage their audience, researchers should design visually appealing posters by presenting high quality data in pictures or graphs without an excess of words.

    1993-01-01

    In previous studies, gram-positive bacteria which grew rapidly with peptides or an amino acid as the sole energy source were isolated from bovine rumina. Three isolates, strains C, FT (T = type strain), and SR, were considered to be ecologically important since they produced up to 20-fold more ammonia than other ammonia-producing ruminal bacteria. On the basis of phenotypic criteria, the taxonomic position of these new isolates was uncertain. In this study, the 16S rRNA sequences of these isolates and related bacteria were determined to establish the phylogenetic positions of the organisms. The sequences of strains C, FT, and SR and reference strains of Peptostreptococcus anaerobius, Clostridium sticklandii, Clostridium coccoides, Clostridium aminovalericum, Acetomaculum ruminis, Clostridium leptum, Clostridium lituseburense, Clostridium acidiurici, and Clostridium barkeri were determined by using a modified Sanger dideoxy chain termination method. Strain C, a large coccus purported to belong to the genus Peptostreptococcus, was closely related to P. anaerobius, with a level of sequence similarity of 99.6%. Strain SR, a heat-resistant, short, rod-shaped organism, was closely related to C. sticklandii, with a level of sequence similarity of 99.9%. However, strain FT, a heat-resistant, pleomorphic, rod-shaped organism, was only distantly related to some clostridial species and P. anaerobius. On the basis of the sequence data, it was clear that strain FT warranted designation as a separate species. The closest known relative of strain FT was C. coccoides (level of similarity, only 90.6%). Additional strains that are phenotypically similar to strain FT were isolated in this study.(ABSTRACT TRUNCATED AT 250 WORDS).

  16. Posters as assessment strategies: focusing on service users.

    Science.gov (United States)

    Crawley, Loretta; Frazer, Kate

    This article debates whether posters as an assessment strategy in health professionals' education programmes can benefit learners, academics, and service users. Evidence suggests that service-user involvement benefits learning by developing students' communication, partnership and advocacy skills. The authors debate the value of posters as an assessment strategy in postgraduate diploma nursing programmes delivered in an Irish School of Nursing, Midwifery and Health Systems. It is argued that assessment strategies should not only examine programme theory and practice but should also benefit the people that will be using the service. Although the assessment strategy used in these programmes aimed to benefit service users, additional work is required for assessment to be truly inclusive of service users.

    Full Text Available Clostridium perfringens is an important pathogen that provokes numerous different diseases. This bacterium is classified into five different types, each of which capable of causing a different disease. There are various methods for the bacterial identification, many are labor-intensive, time-consuming, expensive and also present low sensitivity and specificity. The aim of this research was to identify the different types of C. perfringens using PCR molecular method. In this study, 130 sheep-dung samples were randomly collected from areas around the city of Kerman, southeastern Iran. After processing and culturing of samples, the produced colonies were morphologically studied, gram stain test was also carried out and the genera of these bacteria were identified through biochemical tests. DNA extracted from isolated bacteria for genotyping was tested by multiplex PCR with specific primers. Based on length of synthesized fragments by PCR, toxin types and bacterial strains were detected. C. perfringens isolated types were divided as follows: 17.39% type A, 21.74% type B, 34.78% type C and 26.09% type D. It should be emphasized that, up to the present moment, C. perfringens type A has not been reported in Iran.

  8. The economic burden of Clostridium difficile

    Although Clostridium difficile (C. difficile) is the leading cause of infectious diarrhoea in hospitalized patients, the economic burden of this major nosocomial pathogen for hospitals, third-party payers and society remains unclear. We developed an economic computer simulation model to determine the costs attributable to healthcare-acquired C. difficile infection (CDI) from the hospital, third-party payer and societal perspectives. Sensitivity analyses explored the effects of varying the cost of hospitalization, C. difficile-attributable length of stay, and the probability of initial and secondary recurrences. The median cost of a case ranged from $9179 to $11 456 from the hospital perspective, $8932 to $11 679 from the third-party payor perspective, and $13 310 to $16 464 from the societal perspective. Most of the costs incurred were accrued during a patient’s primary CDI episode. Hospitals with an incidence of 4.1 CDI cases per 100 000 discharges would incur costs ≥$3.2 million (hospital perspective); an incidence of 10.5 would lead to costs ≥$30.6 million. Our model suggests that the annual US economic burden of CDI would be ≥$496 million (hospital perspective), ≥$547 million (third-party payer perspective) and ≥$796 million (societal perspective). Our results show that C. difficile infection is indeed costly, not only to third-party payers and the hospital, but to society as well. These results are consistent with current literature citing C. difficile as a costly disease. PMID:21668576

  9. CLOSTRIDIUM PERFRINGENS IN MEAT AND MEAT PRODUCTS.

    Science.gov (United States)

    HALL, H E; ANGELOTTI, R

    1965-05-01

    A total of 262 specimens of meat and meat dishes were examined for the presence of Clostridium perfringens. Of this total, 161 were raw, unprocessed beef, veal, lamb, pork, or chicken; 101 were processed meats and meat dishes. C. perfringens was isolated from 113 (43.1%) of these specimens. The highest percentage of contamination (82%) was found in veal cuts, and the lowest (4.7%) in sliced sandwich meats and spreads. Only 2 of the 113 isolates were shown to produce heat-resistant spores, which indicates a very low incidence (0.8%) of contamination. These findings indicate that outbreaks of C. perfringens food-borne disease in the Cincinnati area are caused principally by the contamination of the food with vegetative cells or spores of the organism after cooking. Studies of the effects of various holding temperatures on the growth of C. perfringens indicated that, in the range of 5 to 15 C, no multiplication would occur, but that viable cells would still be present at the end of a 5-day holding period. Extremely rapid growth occurred at temperatures around 45 C, and complete inhibition of growth was accomplished between 49 and 52 C.

  10. Clostridium difficile is an autotrophic bacterial pathogen.

    Directory of Open Access Journals (Sweden)

    Michael Köpke

    Full Text Available During the last decade, Clostridium difficile infection showed a dramatic increase in incidence and virulence in the Northern hemisphere. This incessantly challenging disease is the leading cause of antibiotic-associated and nosocomial infectious diarrhea and became life-threatening especially among elderly people. It is generally assumed that all human bacterial pathogens are heterotrophic organisms, being either saccharolytic or proteolytic. So far, this has not been questioned as colonization of the human gut gives access to an environment, rich in organic nutrients. Here, we present data that C. difficile (both clinical and rumen isolates is also able to grow on CO2+H2 as sole carbon and energy source, thus representing the first identified autotrophic bacterial pathogen. Comparison of several different strains revealed high conservation of genes for autotrophic growth and showed that the ability to use gas mixtures for growth decreases or is lost upon prolonged culturing under heterotrophic conditions. The metabolic flexibility of C. difficile (heterotrophic growth on various substrates as well as autotrophy could allow the organism in the gut to avoid competition by niche differentiation and contribute to its survival when stressed or in unfavorable conditions that cause death to other bacteria. This may be an important trait for the pathogenicity of C. difficile.

  11. Phosphorylation of proteins in Clostridium thermohydrosulfuricum

    International Nuclear Information System (INIS)

    Londesborough, J.

    1986-01-01

    Cell extracts of the thermophile Clostridium thermohydrosulfuricum catalyzed the phosphorylation by (γ- 32 P)ATP of several endogenous proteins with M/sub r/s between 13,000 and 100,000. Serine and tyrosine were the main acceptors. Distinct substrate proteins were found in the soluble (e.g., proteins p66, p63, and p53 of M/sub r/s 66,000, 63,000, and 53,000, respectively) and particulate (p76 and p30) fractions, both of which contained protein kinase and phosphatase activity. The soluble fraction suppressed the phosphorylation of particulate proteins and contained a protein kinase inhibitor. Phosphorylation of p53 was promoted by 10μM fructose 1,6-bisphosphate or glucose 1,6-bisphosphate and suppressed by hexose monophosphates, whereas p30 and p13 were suppressed by 5 μM brain (but not spinach) calmodulin. Polyamines, including the odd polyamines characteristic of thermophiles, modulated the labeling of most of the phosphoproteins. Apart from p66, all the proteins labeled in vitro were also rapidly labeled in intact cells by 32 P/sub i/. Several proteins strongly labeled in vivo were labeled slowly or not at all in vitro

    Clostridium difficile infection is the leading cause of hospital-acquired diarrhoea and pseudomembranous colitis. Disease is mediated by the actions of two toxins, TcdA and TcdB, which cause the diarrhoea, as well as inflammation and necrosis within the colon. The toxins are large (308 and 270 kDa, respectively), homologous (47% amino acid identity) glucosyltransferases that target small GTPases within the host. The multidomain toxins enter cells by receptor-mediated endocytosis and, upon exposure to the low pH of the endosome, insert into and deliver two enzymatic domains across the membrane. Eukaryotic inositol-hexakisphosphate (InsP6) binds an autoprocessing domain to activate a proteolysis event that releases the N-terminal glucosyltransferase domain into the cytosol. Here, we report the crystal structure of a 1,832-amino-acid fragment of TcdA (TcdA1832), which reveals a requirement for zinc in the mechanism of toxin autoprocessing and an extended delivery domain that serves as a scaffold for the hydrophobic α-helices involved in pH-dependent pore formation. A surface loop of the delivery domain whose sequence is strictly conserved among all large clostridial toxins is shown to be functionally important, and is highlighted for future efforts in the development of vaccines and novel therapeutics.

  13. Clostridium difficile – From Colonization to Infection

    2018-01-01

    Clostridium difficile is the most frequent cause of nosocomial antibiotic-associated diarrhea. The incidence of C. difficile infection (CDI) has been rising worldwide with subsequent increases in morbidity, mortality, and health care costs. Asymptomatic colonization with C. difficile is common and a high prevalence has been found in specific cohorts, e.g., hospitalized patients, adults in nursing homes and in infants. However, the risk of infection with C. difficile differs significantly between these cohorts. While CDI is a clear indication for therapy, colonization with C. difficile is not believed to be a direct precursor for CDI and therefore does not require treatment. Antibiotic therapy causes alterations of the intestinal microbial composition, enabling C. difficile colonization and consecutive toxin production leading to disruption of the colonic epithelial cells. Clinical symptoms of CDI range from mild diarrhea to potentially life-threatening conditions like pseudomembranous colitis or toxic megacolon. While antibiotics are still the treatment of choice for CDI, new therapies have emerged in recent years such as antibodies against C. difficile toxin B and fecal microbial transfer (FMT). This specific therapy for CDI underscores the role of the indigenous bacterial composition in the prevention of the disease in healthy individuals and its role in the pathogenesis after alteration by antibiotic treatment. In addition to the pathogenesis of CDI, this review focuses on the colonization of C. difficile in the human gut and factors promoting CDI. PMID:29692762

    2017-04-01

    Clostridium difficile infections are characterized by a high recurrence rate despite antibiotic treatments and there is an urgent need to develop new treatments such as fecal transplantation and immonotherapy. Besides active immunotherapy with vaccines, passive immunotherapy has shown promise, especially with monoclonal antibodies. Areas covered: Herein, the authors review the different assays performed with monoclonal antibodies against C. difficile toxins and surface proteins to treat or prevent primary or recurrent episodes of C. difficile infection in animal models and in clinical trials as well. Notably, the authors lay emphasis on the phase III clinical trial (MODIFY II), which allowed bezlotoxumab to be approved by the Food and Drug Administration and the European Medicines Agency. They also review new strategies for producing single domain antibodies and nanobodies against C. difficile and new approaches to deliver them in the digestive tract. Expert opinion: Only two human Mabs against TcdA and TcdB have been tested alone or in combination in clinical trials. However, many animal model studies have provided rationale for the use of Mabs and nanobodies in C. difficile infection and pave the way for further clinical investigation.

  15. [Epidemiology of Clostridium difficile infection in Spain].

    Asensio, Angel; Monge, Diana

    2012-06-01

    There has been increasing interest in Clostridium difficile infection (CDI) due its association with healthcare and its impact on morbidity and mortality in the elderly. During the last few years there has been a growing increase in the number of published studies on the incidence, changes on the clinical presentation and on the epidemiology, with the description of new risk factors. The frequency of CDI in Spain is not sufficiently characterised. The available data indicates that incidence is within the range of that of surrounding countries but increasing. Furthermore, the high and growing use of broad spectrum antibiotics, both in our hospitals and in the community setting, are factors that favour the increase of the disease. The hyper-virulent ribotype 027 has not spread in our hospitals. We need to know with enhanced validity and accuracy the incidence of CDI, both community and healthcare-associated, the information on outbreaks, the incidence on certain population groups, the characterisation of circulating ribotypes and the impact of the disease in terms of mortality and health costs. We need to implement programs for the improvement of antibiotic therapy in the hospital, as well as in the community. Furthermore, the knowledge and the performance of standard precautions need to be improved, particularly hand hygiene, and the specific measures to limit the transmission of C. difficile among the healthcare institutions.

    BACKGROUND: Broad-spectrum antibiotics, particularly intravenous cephalosporins, are associated with Clostridium difficile diarrhoea. Diarrhoea due to C. difficile is a growing problem in hospitals, especially among elderly patients. AIM: To establish whether changing an antibiotic policy with the aim of reducing the use of injectable cephalosporins leads to a reduction in the incidence of C. difficile diarrhoea in elderly patients. DESIGN: Retrospective analysis. METHODS: A group of patients who were subject to the new antibiotic policy from the period following July 2000, were compared with patients who were admitted prior to July 2000 and were not subject to the new policy. Infections, antibiotic prescriptions and mortality rates were determined from case notes, and C. difficle diarrhoea rates from microbiological data. RESULTS: Intravenous cephalosporin use fell from 210 to 28 defined daily doses (p < 0.001) following the change in antibiotic policy, with a corresponding increase in piperacillin-tazobactam (p < 0.001) and moxifloxacin (p < 0.001) use. The new policy led to a significant reduction in C. difficile diarrhoea cases. The relative risk of developing C. difficile infection with the old policy compared to the new policy was 3.24 (95%CI 1.07-9.84, p = 0.03). DISCUSSION: The antibiotic policy was successfully introduced into an elderly care service. It reduced both intravenous cephalosporin use and C. difficile diarrhoea.

    Clostridium septicum is an unusual anaerobic, gram-positive, gas-producing bacillus, which has been identified as a cause of fulminant rapidly fatal infection in humans. Infection with C. septicum usually occurs in patients with cancer, patients receiving immunosuppressive chemotherapy, or patients with a nonmalignant hematological disorder such as hemolytic uremic syndrome. C. septicum infection most commonly involves the abdomen, and a recent review article has identified 164 cases in the medical literature describing the abdominal findings in this disease. Intracranial manifestation of C. septicum infection are less common and include meningitis, cerebritis, abscess formation and pneumocephalus. There have been only 12 documented cases in the English literature describing central nervous system lesions associated with C. septicum. We present a case report of a 56-year-old man in whom septicemia due to C. septicum developed as a complication of Crohn's disease. To our knowledge, there has never been a previous report of C. septicum sepsis related to underlying Crohn's disease. Our case is also remarkable in that an intracerebral gas collection developed at the site of a mycotic infarct related to C. septicum bacteremia, Intracranial, intraparenchymal gas formation related to anaerobic infection is extremely rare; to our knowledge, this radiological finding related to C. septicum sepsis has been described in only 1 previous case report in the medical literature. We also describe the intra-abdominal manifestations of C. septicum sepsis that occurred in this patient as well as the associated radiographic and pathologic findings. (author)

    The anaerobic bacterium Clostridium perfringens expresses multiple toxins that promote disease development in both humans and animals. One such toxin is perfringolysin O (PFO, classically referred to as θ toxin), a pore-forming cholesterol-dependent cytolysin (CDC). PFO is secreted as a water-soluble monomer that recognizes and binds membranes via cholesterol. Membrane-bound monomers undergo structural changes that culminate in the formation of an oligomerized prepore complex on the membrane surface. The prepore then undergoes conversion into the bilayer-spanning pore measuring approximately 250-300 Å in diameter. PFO is expressed in nearly all identified C. perfringens strains and harbors interesting traits that suggest a potential undefined role for PFO in disease development. Research has demonstrated a role for PFO in gas gangrene progression and bovine necrohemorrhagic enteritis, but there is limited data available to determine if PFO also functions in additional disease presentations caused by C. perfringens. This review summarizes the known structural and functional characteristics of PFO, while highlighting recent insights into the potential contributions of PFO to disease pathogenesis.

  1. Developing a professional poster: four "ps" for advanced practice nurses to consider.

    2013-01-01

    Professional posters play an important role in the dissemination of knowledge and the professional development of advanced practice nurses, graduate students, and clinical faculty. Posters should be considered an integral component in communication of professional work in practice, research, and education. The invitation to submit a poster abstract is an important opportunity for clinicians and faculty alike to consider. Though sometimes misperceived as less prestigious than a podium presentation, posters add a unique element to professional and academic events. The argument is made for posters as an equal among scholarly presentation formats. The poster serves as a tremendous opportunity for collaboration between partners and a way to communicate important findings and advertise the presenters' work. For the advanced practice nurse who is a novice in presenting best practice or evidence from research trials, the poster format may be less intimidating while allowing the invaluable sharing of results. Four critical elements of professional poster development are deciding on a clear Purpose, targeting the right People, outlining key steps in the Process, and delivering a memorable Presentation. Using the "4 Ps" as cornerstones for the work of developing, preparing, and delivering the poster to an audience, the authors aim to help organize the entire process into these essential considerations. The poster, as a means of scholarly work, is a viable and essential activity, as interdisciplinary collaboration and sharing of best practice becomes the expectation for all professional development.

    Residents demonstrate scholarly activity by presenting posters at academic meetings. Although recommendations from national organizations are available, evidence identifying which components are most important is not. To develop and test an evaluation tool to measure the quality of case report posters and identify the specific components most in need of improvement. Faculty evaluators reviewed case report posters and provided on-site feedback to presenters at poster sessions of four annual academic general internal medicine meetings. A newly developed ten-item evaluation form measured poster quality for specific components of content, discussion, and format (5-point Likert scale, 1 = lowest, 5 = highest). Evaluation tool performance, including Cronbach alpha and inter-rater reliability, overall poster scores, differences across meetings and evaluators and specific components of the posters most in need of improvement. Forty-five evaluators from 20 medical institutions reviewed 347 posters. Cronbach's alpha of the evaluation form was 0.84 and inter-rater reliability, Spearman's rho 0.49 (p words. Our evaluation tool provides empirical data to guide trainees as they prepare posters for presentation which may improve poster quality and enhance their scholarly productivity.

    Currently poster presentations offer a common visual medium for knowledge transfer by a wide range of health professionals. Our study aimed to determine the scientific importance of poster presentations for Medical and Radiation Oncologists. A survey form including 40 questions was distributed to a total of 131 oncologists experienced in poster presentations. One hundred completed survey forms were included in the study. Descriptive statistics and modified thematic analyses were performed on the responses. Overall 64% of the participants agreed that posters were a good medium for knowledge transfer. Some 88% agreed that concise and clear styled presentations would increase appealing interests for poster contents. Visual appearance was cited more influential than content of the subject; 70% of participants agreed that appearances of posters could help to draw more viewer attention. Of respondents, 63% believed that posters accompanied by their author were more attractive for congress attendees, and 33% of them declared that the halo effect of the poster presenter was also important. The present study indicated that intelligibility, appearance and visuality of posters are most important factors from the aspect of oncologist participants. Presenters must take into account these important points when preparing their academic posters.

    The presentation of scientific posters gives young scientists the opportunity to present their data in the setting of a medical congress. In preparation of the organization of the 116th Congress of the German Society of Internal Medicine (DGIM) 2010, the authors evaluated the poster rounds at the 115th Congress of the DGIM 2009 by using a questionnaire that was given to poster presenters, poster chairmen, and visitors. The authors sought to receive an instructive criticism for the organization in 2010. Distribution of questionnaires containing ten questions with preformulated response options and an additional field for further comments to all presenters, chairmen, and visitors of the poster rounds during the 115th Congress of the DGIM (April 2009). 159 questionnaires were returned and evaluated. Almost all respondents quoted the poster presentation as being important for their scientific work (98%). In general, they were satisfied with the discussion at the poster rounds (83%). The amount of posters within one round was criticized by 41%, as was the inadequate adherence to time constraints and time frame and room conditions themselves. The poster exhibition of the 115th Congress of the DGIM 2009 was evaluated positively by most of the respondents to the survey. Nevertheless, helpful hints were retrieved as how to further improve poster rounds. They should be respected when planning the exhibition at the congress in 2010.

  5. The Clostridium sporulation programs: diversity and preservation of endospore differentiation.

    Bacillus and Clostridium organisms initiate the sporulation process when unfavorable conditions are detected. The sporulation process is a carefully orchestrated cascade of events at both the transcriptional and posttranslational levels involving a multitude of sigma factors, transcription factors, proteases, and phosphatases. Like Bacillus genomes, sequenced Clostridium genomes contain genes for all major sporulation-specific transcription and sigma factors (spo0A, sigH, sigF, sigE, sigG, and sigK) that orchestrate the sporulation program. However, recent studies have shown that there are substantial differences in the sporulation programs between the two genera as well as among different Clostridium species. First, in the absence of a Bacillus-like phosphorelay system, activation of Spo0A in Clostridium organisms is carried out by a number of orphan histidine kinases. Second, downstream of Spo0A, the transcriptional and posttranslational regulation of the canonical set of four sporulation-specific sigma factors (σ(F), σ(E), σ(G), and σ(K)) display different patterns, not only compared to Bacillus but also among Clostridium organisms. Finally, recent studies demonstrated that σ(K), the last sigma factor to be activated according to the Bacillus subtilis model, is involved in the very early stages of sporulation in Clostridium acetobutylicum, C. perfringens, and C. botulinum as well as in the very late stages of spore maturation in C. acetobutylicum. Despite profound differences in initiation, propagation, and orchestration of expression of spore morphogenetic components, these findings demonstrate not only the robustness of the endospore sporulation program but also the plasticity of the program to generate different complex phenotypes, some apparently regulated at the epigenetic level.

    Clostridium difficile is posing urgent health threats. Older studies have shown that metronidazole and vancomycin are equally effective in the treatment of Clostridium difficile infection (CDI). Given its inexpensive cost and low propensity to select antimicrobial resistant organisms, metronidazole became rapidly the drug of choice despite its pharmacokinetic limitations in the treatment of CDI. However, newer studies demonstrated that metronidazole is inferior to vancomycin, prompting clinicians to change their long-standing position on using metronidazole for mild to moderate infections and on reserving vancomycin for severe infections. Moving forward, metronidazole will fall out of favor in the treatment of CDI.

Abstract Objective – To map the development and use of poster presentations in order to determine disciplines in which they are particularly prolific and how their popularity or presence may have changed over time. This will potentially assist health and interdisciplinary librarians asked to search for poster presentations in systematic reviews. Design – Informetric mapping review. Setting – An unnamed UK University Library search facility which processes 249 international databases and research publications. Databases and publications range across 37 research disciplines, including literature, medicine, and engineering. Subjects – Published literature connected to poster presentations – the authors state that this could be poster presentations themselves, abstracts, title listings in conference proceedings, or any variety of materials. They also state that over 99% of the results of this review were title citations or abstracts of conference poster presentations. Methods – An informetric mapping review was conducted via a UK University Library search facility by searching for the term “poster presentation” in 249 databases spanning 37 research areas. An index of databases used is provided as an appendix to the article. Results were not connected by the search facility to an individual database. Search results were categorized by discipline and decade of publication. Scholarly and peer-reviewed search limiters were used to obtain an idea of the themes and contributions to what could be considered core literature, and the search was also run in Google Scholar to provide a comparator. Duplications across databases were removed by the search service, although several results appeared both in aggregate (for example, conference proceedings encompassing all poster presentations and

  8. Pleiotropic roles of Clostridium difficile sin locus

    Clostridium difficile is the primary cause of nosocomial diarrhea and pseudomembranous colitis. It produces dormant spores, which serve as an infectious vehicle responsible for transmission of the disease and persistence of the organism in the environment. In Bacillus subtilis, the sin locus coding SinR (113 aa) and SinI (57 aa) is responsible for sporulation inhibition. In B. subtilis, SinR mainly acts as a repressor of its target genes to control sporulation, biofilm formation, and autolysis. SinI is an inhibitor of SinR, so their interaction determines whether SinR can inhibit its target gene expression. The C. difficile genome carries two sinR homologs in the operon that we named sinR and sinR’, coding for SinR (112 aa) and SinR’ (105 aa), respectively. In this study, we constructed and characterized sin locus mutants in two different C. difficile strains R20291 and JIR8094, to decipher the locus’s role in C. difficile physiology. Transcriptome analysis of the sinRR’ mutants revealed their pleiotropic roles in controlling several pathways including sporulation, toxin production, and motility in C. difficile. Through various genetic and biochemical experiments, we have shown that SinR can regulate transcription of key regulators in these pathways, which includes sigD, spo0A, and codY. We have found that SinR’ acts as an antagonist to SinR by blocking its repressor activity. Using a hamster model, we have also demonstrated that the sin locus is needed for successful C. difficile infection. This study reveals the sin locus as a central link that connects the gene regulatory networks of sporulation, toxin production, and motility; three key pathways that are important for C. difficile pathogenesis.

    Virulent strains of Clostridium difficile have become a global health problem associated with morbidity and mortality. Traditional typing methods do not provide ideal resolution to track outbreak strains, ascertain genetic diversity between isolates, or monitor the phylogeny of this species on a global basis. Here, we investigate the occurrence and diversity of clustered regularly interspaced short palindromic repeats (CRISPR) and CRISPR-associated genes (cas) in C. difficile to assess the potential of CRISPR-based phylogeny and high-resolution genotyping. A single Type-IB CRISPR-Cas system was identified in 217 analyzed genomes with cas gene clusters present at conserved chromosomal locations, suggesting vertical evolution of the system, assessing a total of 1,865 CRISPR arrays. The CRISPR arrays, markedly enriched (8.5 arrays/genome) compared with other species, occur both at conserved and variable locations across strains, and thus provide a basis for typing based on locus occurrence and spacer polymorphism. Clustering of strains by array composition correlated with sequence type (ST) analysis. Spacer content and polymorphism within conserved CRISPR arrays revealed phylogenetic relationship across clades and within ST. Spacer polymorphisms of conserved arrays were instrumental for differentiating closely related strains, e.g., ST1/RT027/B1 strains and pathogenicity locus encoding ST3/RT001 strains. CRISPR spacers showed sequence similarity to phage sequences, which is consistent with the native role of CRISPR-Cas as adaptive immune systems in bacteria. Overall, CRISPR-Cas sequences constitute a valuable basis for genotyping of C. difficile isolates, provide insights into the micro-evolutionary events that occur between closely related strains, and reflect the evolutionary trajectory of these genomes. © The Author(s) 2016.

    Despite some case reports, the importance of Clostridium perfringens and Clostridium difficile for wild carnivores remains unclear. Thus, the objective of this study was to identify C. perfringens and C. difficile strains in stool samples from wild carnivore species in Brazil. A total of 34 stool samples were collected and subjected to C. perfringens and C. difficile isolation. Suggestive colonies of C. perfringens were then analyzed for genes encoding the major C. perfringens toxins (alpha, beta, epsilon and iota) and the beta-2 toxin (cpb2), enterotoxin (cpe) and NetB (netb) genes. C. difficile strains were analyzed by multiplex-PCR for toxins A (tcdA) and B (tcdB) and a binary toxin gene (cdtB) and also submitted to a PCR ribotyping. Unthawed aliquots of samples positive for C. difficile isolation were subjected to the detection of A/B toxins by a cytotoxicity assay (CTA). C. perfringens was isolated from 26 samples (76.5%), all of which were genotyped as type A. The netb gene was not detected, whereas the cpb2 and cpe genes were found in nine and three C. perfringens strains, respectively. C. difficile was isolated from two (5.9%) samples. A non-toxigenic strain was recovered from a non-diarrheic maned wolf (Chrysocyon brachyurus). Conversely, a toxigenic strain was found in the sample of a diarrheic ocelot (Leopardus pardallis); an unthawed stool sample was also positive for A/B toxins by CTA, indicating a diagnosis of C. difficile-associated diarrhea in this animal. The present work suggests that wild carnivore species could carry C. difficile strains and that they could be susceptible to C. difficile infection. Copyright © 2014 Elsevier Ltd.

    Boullata, Joseph I; Mancuso, Carissa E

    2007-12-01

    The preparation of an abstract or poster to share information from a project or case report with colleagues is a professional goal for many nutrition support practitioners. This paper provides an approach to help practitioners prepare an abstract for submission and subsequently a poster for presentation at a meeting. A nutrition support question that required collecting and evaluating information, or a unique patient case or case series, can serve as the focus of an abstract and subsequent poster. The professional meeting selected should be appropriate for the abstract topic, and the authors should closely adhere to the organization's abstract submission guidelines. The well-prepared abstract will then serve as the outline for the poster content; the visual aspect of the poster is also important to effectively communicate the information to colleagues at the meeting. Adequate time is required to prepare both the abstract and the poster in order to fittingly reflect the value of the information. Efforts in preparing the abstract will be worthwhile once the abstract has been accepted by reviewers for a poster session at the meeting. Likewise, the effort in preparing the poster in advance allows the presenter to enjoy the poster session and discuss the project with colleagues.

  20. Uterine Clostridium perfringens infection related to gynecologic malignancy.

    Kremer, Kevin M; McDonald, Megan E; Goodheart, Michael J

    2017-11-01

    Uterine gas gangrene caused by Clostridium perfringens is a serious, often life-threatening infection that is rarely encountered in the practice of gynecologic oncology. However, the hypoxic nature of gynecologic cancers due to necrosis and/or prior radiation therapy creates a microenvironment optimal for proliferation of anaerobic bacteria such as the Clostridium species. Early recognition and aggressive treatment with IV antibiotics and surgical debridement remain the cornerstones of management in order to decrease morbidity and mortality. Here we present the case of a 52 year-old woman with a remote history of cervical cancer who was previously treated at our institution with primary chemotherapy and radiation and was then admitted decades later with Clostridium perfringens bacteremia and CT evidence of intrauterine abscess. The patient received a prolonged course of IV antibiotic therapy and subsequently underwent definitive surgical management with a total abdominal hysterectomy, bilateral salpingo-oophorectomy, small bowel resection with anastomosis for a utero-ileal fistula identified intraoperatively. Pathology from the uterine specimen demonstrated a primary poorly differentiated uterine adenocarcinoma. The patient recovered fully from her Clostridium perfringens infection and was discharged from the hospital shortly after surgical intervention.

    The Advanced Photon Source (APS), which is currently under construction as a national user facility at Argonne National Laboratory is a third-generation synchrotron x-ray source, one of only three in the world. It is expected to produce x-rays that are 10,000 times brighter than any currently produced elsewhere for use in research in a wide range of scientific areas. Users from industry, national laboratories, universities, and business will be able to come to the APS to conduct research either as members of Collaborative Access Teams (CATS) or as Independent Investigators. Principal users will be members of CATS, which will be building and operating all of the beamlines present in the first phase of APS beamline development. The first set of CATs has been selected through a competitive proposal process involving peer scientific review, thorough technical evaluation, and significant management oversight by the APS. This document is a compilation of posters presented at the Fifth Users Meeting for the Advanced Photon Source, held at Argonne National Laboratory on October 14--15, 1992. All CATs whose scientific cases were approved by the APS Proposal Evaluation Board are included. In addition, this document contains a poster from the Center for Synchrotron Radiation and Research and Instrumentation at the Illinois Institute of Technology

  6. Ontario FIT - From poster child to industry crisis

    International Nuclear Information System (INIS)

    Roeper, Uwe

    2011-01-01

    Ortech is a consulting firm that provides engineering services to investors and developers in planning and operating solar, wind and water projects. This study discusses the issues involved in the renewable energy Feed-in Tariff (FIT) program in Ontario. Initially hailed as the poster child of innovative renewable programs in North America, the FIT program has been under increasing attack from political parties, anti wind groups and legal suits. The reason was the negative media coverage of noise, birdlife and health effects. Criticism was first voiced over health concerns and lack of consultation. Local governments and the legislature debated these issues and began to split along political lines over them. The lack of public support was because there was insufficient effort put into creating public awareness. Boosting grass-roots support by creating awareness is a recommendation of the paper, which also emphasises the need for a win-win strategy when the government is involved. It can be concluded that the FIT program has gone from poster child to industry crisis but has provided several learning opportunities along the way.

  7. Posters That Teach – Blended Learning and Total Engagement

    2017-08-01

    Full Text Available Electronically mediated technologies are prohibited from use in a major assessment component of a blended learning subject. This subject employs a multidisciplinary problem-based approach to explore international issues and perspectives using a rich blend of face-to-face, electronically mediated, individual and team-based activities. The assessment is a role-play which occurs during the second half of a year-long pathway to university program. Belief in the importance of helping students integrate knowledge with an understanding of learning strategies informs the design of this particular assessment task. To complete the task, small teams develop and display a hand-drawn poster summarising their understanding of a real life 'wicked problem' explored in depth during the semester. Composing and preparing their poster ensures that students create visual evidence of their learning about the context of a complex contemporary international issue, which varies from year to year. It also introduces students to higher order thinking and develops critical and creative thinking skills. This paper aims to introduce and describe the learning principles informing the design of the assessment strategy. The task compels students to question information, seeking deeper engagement with data and generating first-hand engagement with the issue. The learning design also facilitates students’ crucial skills of knowledge generation and learning management, and helps them apply this knowledge to other aspects of their future learning. This task bridges the gap between the technical and non-technical skills essential for success in the 21st century.

    National orthopaedic meetings are used to disseminate current research through podium and poster abstract presentations. Not all of these abstracts go on to full-text journal publication. The purpose of this study was to determine the publication rates of podium and poster presentations from the American Orthopaedic Foot & Ankle Society (AOFAS) annual meetings between 2008 and 2012. All accepted podium and poster abstracts from the 2008-2012 AOFAS annual meetings were compiled from the AOFAS office, Physician Resource Center website, and hardcopy meeting programs. PubMed and Google Scholar searches were performed for journal publications using key words in the presentation abstracts and authors' names. Full-text journal publication rates for the presentations were calculated per year, as were the most common journals of publication. Overall full-text publication rate was 73.7% for podium presentations and 55.8% for posters. Podium presentations were published in a journal significantly more often than posters ( P poster presentations, respectively ( P = .124). The most common journal for podium and poster publications was Foot & Ankle International. Podium abstracts were significantly more likely to be published compared to posters. The AOFAS overall full-text journal publication rate was one of the higher reported rates compared with other national orthopedic society meetings, which have ranged from 34% to 73%.

    2015-01-01

    Cystic fibrosis (CF) health care professionals recognize the need to motivate people with CF to adhere to nebulizer treatments, yet little is known about how best to achieve this. We aimed to produce motivational posters to support nebulizer adherence by using social marketing involving people with CF in the development of those posters. The Sheffield CF multidisciplinary team produced preliminary ideas that were elaborated upon with semi-structured interviews among people with CF to explore barriers and facilitators to the use of nebulized therapy. Initial themes and poster designs were refined using an online focus group to finalize the poster designs. People with CF preferred aspirational posters describing what could be achieved through adherence in contrast to posters that highlighted the adverse consequences of nonadherence. A total of 14 posters were produced through this process. People with CF can be engaged to develop promotional material to support adherence, providing a unique perspective differing from that of the CF multidisciplinary team. Further research is needed to evaluate the effectiveness of these posters to support nebulizer adherence.

    2017-03-01

    : Background: Nurses developing a poster presentation for the first time who look for guidance in the literature will find many articles offering recommendations on format and style, but these are based on opinion rather than evidence. The purpose of this study was to identify the attributes of a poster that improved the chance that nursing conference attendees would read it. A mixed-methods descriptive study employing survey methodology was used to assess the perceptions of nurses attending poster sessions at a two-day nursing conference. The survey consisted of basic demographic questions, 25 items asking respondents to identify and rate the importance of variables that influenced their decision to read a poster, and several open-ended questions. Both a qualitative and quantitative analysis of the responses was performed. The two major themes that emerged from the qualitative analysis were that poster-viewing decisions were based first on aesthetics and then on relevance. The quantitative analysis identified aesthetic characteristics that were most important to nurse viewers, including overall visual appeal, color, organization, and layout; viewers determined the relevance of a poster primarily by reading its title. To develop a poster that will attract an audience, nurse researchers should keep in mind the attributes that are important to their peers and colleagues. Conference attendees are more likely to read a poster if it's on a topic that interests them, is pleasing to the eye, and has a title that's easy to read.

    Grass hay is one of assailable cellulose containing non-food agricultural wastes that can be used as a carbohydrate source by microorganisms producing biofuels. In this study three Clostridium strains Clostridium acetobutylicum, Clostridium beijerinckii and Clostridium tetanomorphum, capable of producing acetone, butanol and ethanol (ABE) were adapted to convert enzymatically hydrolyzed hay used as a growth media additive. The results of growth curves, substrate degradation kinetics and FT-IR analyses of bacterial biomass macromolecular composition showed diverse strain-specific cell response to the growth medium composition.

    Clostridium difficile infection is a healthcare-associated infection resulting in significant morbidity. Although immunosuppression is associated with Clostridium difficile infection acquisition and adverse outcomes, the epidemiology of Clostridium difficile infection in HIV-infected patients has been little studied in the era of antiretroviral therapy. This study identifies the risk factors for acquisition of Clostridium difficile infection in HIV-infected patients. A retrospective, propensity score-matched case-control study design was employed, with patients selected from our institution's outpatient HIV clinic. Clostridium difficile infection cases were defined as having positive stool testing plus an appropriate clinical presentation. The propensity score was generated via multiple logistic regression from year of HIV diagnosis, age at first contact, duration of follow-up, gender, and initial CD4 count. The 46 cases included were matched to a total of 180 controls. Prior antibiotic treatment was a significant predictor of Clostridium difficile infection (odds ratio: 13, 95% confidence interval: 3.49-48.8, p  Clostridium difficile infection in the multivariable model (odds ratio: 15.17, confidence interval: 1.31-175.9, p  = .021). As in the general population, frequent hospitalizations and exposure to antimicrobials are independent predictors of Clostridium difficile infection acquisition in patients with HIV. Additionally, low CD4 count and proton pump inhibitor use are new potentially modifiable variables that can be targeted for prevention of Clostridium difficile infection in future interventional studies.

    2015-09-01

    To determine if an opioid prescribing guideline poster, meant to be posted in an emergency department (ED) triage area, would deter patients with chronic pain from seeking care. We prospectively enrolled patients presenting to a chronic craniofacial pain clinic affiliated with an urban academic Level I trauma center. Patients were surveyed with a close-ended, structured questionnaire. Included patients were aged 18 and older with pain lasting 12 weeks or longer. Patients were shown a sample pain poster. The primary outcome was determination if such a poster would prevent the patient from staying to receive care in the ED. One hundred patients were surveyed. Most patients (77%) reported having been a patient in the ED in the past, and of these, 23% reported visiting the ED for worsening of chronic pain. After being shown the poster, 97% believed the recommendations in the poster were reasonable and 97% thought that the poster should be displayed in the ED. Seven patients (7%) reported that seeing the poster in the ED waiting room or triage area would intimidate them, and two patients within this group (2% of total sample) reported that it would prevent them from staying to get care. The vast majority of patients with chronic pain in this cohort believes that a pain guideline poster is reasonable and should be posted in the ED. However, a small percentage of patients reported that they would feel intimidated by such a poster and that it would prevent them from staying to get care, a result meant to inform hospitals and policy-makers deciding if such posters should be displayed.

    2013-01-01

    Bacteria of the Clostridium genus are often described only as a biological threat and a foe of mankind. However, many of them have positive properties and thanks to them they may be used in many industry branches (e.g., in solvents and alcohol production, in medicine, and also in esthetic cosmetology). During the last 10 years interest in application of C. botulinum and C. tetani in medicine significantly increased. Currently, the structure and biochemical properties of neurotoxins produced by these bacterial species, as well as possibilities of application of such toxins as botulinum as a therapeutic factor in humans, are being intensely researched. The main aim of this article is to demonstrate that bacteria from Clostridium spp. are not only pathogens and the enemy of humanity but they also have many important beneficial properties which make them usable among many chemical, medical, and cosmetic applications.

  12. Models for the study of Clostridium difficile infection

    Best, Emma L.; Freeman, Jane; Wilcox, Mark H.

    2012-01-01

    Models of Clostridium difficile infection (C. difficile) have been used extensively for Clostridium difficile (C. difficile) research. The hamster model of C. difficile infection has been most extensively employed for the study of C. difficile and this has been used in many different areas of research, including the induction of C. difficile, the testing of new treatments, population dynamics and characterization of virulence. Investigations using in vitro models for C. difficile introduced the concept of colonization resistance, evaluated the role of antibiotics in C. difficile development, explored population dynamics and have been useful in the evaluation of C. difficile treatments. Experiments using models have major advantages over clinical studies and have been indispensible in furthering C. difficile research. It is important for future study programs to carefully consider the approach to use and therefore be better placed to inform the design and interpretation of clinical studies. PMID:22555466

    Public-display systems are still far from being a medium for meeting people's diverse communication goals. Moving toward open displays will require publication paradigms that can overcome the challenges of meaningful engagement and enable users to fully understand and control the publication process. The metaphors of pins and posters have inspired two complementary paradigms for public displays. Researchers implemented these paradigms in the Instant Places system, which they deployed on 10 displays in diverse urban locations for six months. They collected user and system data regarding the users' practices. The findings improve the understanding of what might drive user-generated content in networks of urban displays. Such knowledge can inform the design of tools and procedures for situated publication in public displays.

    2012-02-01

    To evaluate the pharmacology, microbiology, safety, and efficacy of fidaxomicin for treatment of Clostridium difficile infections (CDI). Literature was identified through Ovid MEDLINE (1948-December 2011) and International Pharmaceutical Abstracts (1970-December 2011) using the search terms fidaxomicin, OPT-80, PAR-101, OP-118, difimicin, tiacumicin, lipiarmycin, Clostridium difficile, Clostridium difficile infection, Clostridium difficile-associated diarrhea, and cost. Drug monographs were retrieved from manufacturers' Web pages, and the Red Book component of Micromedex was used for cost information. All pertinent Phase 1, 2, and 3 studies published in English were included. Fidaxomicin is a macrocyclic compound bactericidal against C. difficile and inhibits toxin and spore production. It has poor oral absorption with high fecal concentrations. Available Phase 2 and 3 data with fidaxomicin 200 mg orally every 12 hours demonstrate similar effectiveness in treating CDI compared to oral vancomycin. Fidaxomicin was shown to have less frequency of recurrent infections. Adverse effects are uncommon and occur at similar rates as with oral vancomycin. The most frequently reported adverse effects are gastrointestinal, hematologic, and electrolyte disorders. Available data are lacking in several areas, including the efficacy and safety of fidaxomicin compared to established regimens for mild-to-moderate, life-threatening, and recurrent CDIs. The cost of a 10-day course of fidaxomicin is significantly more than that of metronidazole and vancomycin for treatment of mild-to-moderate CDI. Fidaxomicin appears to be an effective and safe alternative to oral vancomycin for treatment of mild-to-moderate and severe CDI. Data on its use compared to guideline-recommended therapies for mild-to-moderate and life-threatening CDI are needed. Further data assessing the cost-effectiveness of fidaxomicin are needed. Currently, it cannot be recommended over vancomycin for treatment of CDI

    Clostridium thermocellum, a thermophilic anaerobe, directly converts cellulose to EtOH. To estimate its EtOH production from cellulose, we used a new method based on material balance by which the efficiencies of the enzymes that convert cellulose to ethanol were calculated. Using this method, the maximum efficiency of ethanol production of two strains of C. thermocellum was estimated to be 0.05, with 0.67 as the theoretical maximum. 3 references.

    Healthcare decision-makers are increasingly expected to balance increasing demand for health services with a finite budget. The role of economic evaluation in healthcare is increasing and this research provides decision-makers with new information about the management of Clostridium difficile infection, from an economic perspective. A model-based economic evaluation was undertaken to identify the most cost-effective healthcare intervention relating to the reduction of Clostridium difficile transmission. Efficacy evidence was synthesised from the literature and was used to inform the effectiveness of both bundled approaches and stand-alone interventions, where appropriate intervention combinations were coupled together. Changes in health outcomes were estimated by combining information about intervention effectiveness and its subsequent impact on quality of life. A bundled approach of improving hand hygiene and environmental cleaning produces the best combination of increased health benefits and cost-savings. It has the highest mean net monetary benefit when compared to all other interventions. This intervention remains the optimal decision under different clinical circumstances, such as when mortality rate and patient length of stay are increased. Bundled interventions offered the best opportunity for health improvements. These findings provide healthcare decision-makers with novel information about the allocation of scarce resources relating to Clostridium difficile. If investments are not made in interventions that clearly yield gains in health outcomes, the allocation and use of scarce healthcare resources is inappropriate and improvements in health outcomes will be forgone.

  3. SEVERE CLOSTRIDIUM DIFFICILE INFECTIONS. A SYSTEMATIC LITERATURE -review-

    Directory of Open Access Journals (Sweden)

    Adriana Elena NICA

    2016-06-01

    Full Text Available Clostridium difficile is a bacterium that has been brought to the attention of the medical community recently, as the number of infections related to it has increased dramatically. This is happening mainly because of the excessive and defective use of antibiotic therapy. The pathology of a Clostridium Difficile infection is very complex, as it ranges from easy symptoms like abdominal pain and diarrhea to severe complications, like toxic megacolon. The management of these infections has become even more difficult, as they are not appearing only in the hospital environment anymore, but also outside of it. The bacterium spreads through poor hands hygiene. Also, we don’t have a clear strategy for overcoming an infection like this, so it gets even more difficult as most of the times the doctors need to rely only on their experience and knowledge to find ways of battling it. We would like to underline the research opportunities that are available in this domain as very few things are known about Clostridium difficile and also the crucial importance of research, as these infections are common and dangerous not only for patients, but for the medical staff and their families too.

    Full Text Available Fredy Chaparro-Rojas, Kathleen M MullaneDepartment of Medicine, Section of Infectious Diseases, University of Chicago, Chicago, IL, USAAbstract: The epidemiology of Clostridium difficile infections (CDI has evolved during the last decades, with an increase in the reported incidence, severity of cases, and rate of mortality and relapses. These increases have primarily affected some special populations including the elderly, patients requiring concomitant antibiotic therapy, patients with renal failure, and patients with cancer. Until recently, the treatment of CDI was limited to either metronidazole or vancomycin. New therapeutic options have emerged to address the shortcomings of current antibiotic therapy. Fidaxomicin stands out as the first-in-class oral macrocyclic antibiotic with targeted activity against C. difficile and minimal collateral damage on the normal colonic flora. Fidaxomicin has demonstrated performance not inferior to what is considered the “gold standard” available therapy for CDI, vancomycin, in two separate Phase III clinical trials, but with significant advantages, including fewer recurrences and higher rates of sustained clinical cures. Fidaxomicin constitutes an important development in targeted antibiotic therapy for CDI and must be considered as a first-line agent for patients with risk factors known to portend relapse and severe infection.Keywords: fidaxomicin, Clostridium difficile-associated diarrhea, CDAD, Clostridium difficile infection (CDI, vancomycin, metronidazole

    2016-01-01

    Environmental cues can affect food decisions. There is growing evidence that environmental cues influence how much one consumes. This article demonstrates that environmental cues can similarly impact the healthiness of consumers' food choices. Two field studies examined this effect with consumers of vending machine foods who were exposed to different posters. In field study 1, consumers with a health-evoking nature poster compared to a pleasure-evoking fun fair poster or no poster in their visual sight were more likely to opt for healthy snacks. Consumers were also more likely to buy healthy snacks when primed by an activity poster than when exposed to the fun fair poster. In field study 2, this consumer pattern recurred with a poster of skinny Giacometti sculptures. Overall, the results extend the mainly laboratory-based evidence by demonstrating the health-relevant impact of environmental cues on food decisions in the field. Results are discussed in light of priming literature emphasizing the relevance of preexisting associations, mental concepts and goals. Copyright © 2015 Elsevier Ltd. All rights reserved.

    The objective of this study was to evaluate the clinical characteristics and outcomes of hospitalized patients tested for Clostridium difficile and determine the correlation between pretest probability for C. difficile infection (CDI) and assay results. Patients with testing ordered for C. difficile were enrolled and assigned a high, medium, or low pretest probability of CDI based on clinical evaluation, laboratory, and imaging results. Stool was tested for C. difficile by toxin enzyme immunoassay (EIA) and toxigenic culture (TC). Chi-square analyses and the log rank test were utilized. Among the 111 patients enrolled, stool samples from nine were TC positive and four were EIA positive. Sixty-one (55%) patients had clinically significant diarrhea, 19 (17%) patients did not, and clinically significant diarrhea could not be determined for 31 (28%) patients. Seventy-two (65%) patients were assessed as having a low pretest probability of having CDI, 34 (31%) as having a medium probability, and 5 (5%) as having a high probability. None of the patients with low pretest probabilities had a positive EIA, but four were TC positive. None of the seven patients with a positive TC but a negative index EIA developed CDI within 30 days after the index test or died within 90 days after the index toxin EIA date. Pretest probability for CDI should be considered prior to ordering C. difficile testing and must be taken into account when interpreting test results. CDI is a clinical diagnosis supported by laboratory data, and the detection of toxigenic C. difficile in stool does not necessarily confirm the diagnosis of CDI.

    In our course of Biomedical Imaging, we introduced a research project as an assignment that included an online poster presentation. To assess the assignment, an adjusted criteria sheet was created, where it facilitated providing students with an effective feedback linked to particular criteria. Students are expected to produce a scientific poster to present the result of their investigation and upload it to an online discussion board. In addition, they are required to read their colleagues' works and provide peer-feedback by asking quality questions about principles and results, also on-line. Subtle distribution of marks in the rubric balances focus between preparing poster and providing peer-feedbacks.

    Full Text Available Abstract Background Communities of microorganisms control the rates of key biogeochemical cycles, and are important for biotechnology, bioremediation, and industrial microbiological processes. For this reason, we constructed a model microbial community comprised of three species dependent on trophic interactions. The three species microbial community was comprised of Clostridium cellulolyticum, Desulfovibrio vulgaris Hildenborough, and Geobacter sulfurreducens and was grown under continuous culture conditions. Cellobiose served as the carbon and energy source for C. cellulolyticum, whereas D. vulgaris and G. sulfurreducens derived carbon and energy from the metabolic products of cellobiose fermentation and were provided with sulfate and fumarate respectively as electron acceptors. Results qPCR monitoring of the culture revealed C. cellulolyticum to be dominant as expected and confirmed the presence of D. vulgaris and G. sulfurreducens. Proposed metabolic modeling of carbon and electron flow of the three-species community indicated that the growth of C. cellulolyticum and D. vulgaris were electron donor limited whereas G. sulfurreducens was electron acceptor limited. Conclusions The results demonstrate that C. cellulolyticum, D. vulgaris, and G. sulfurreducens can be grown in coculture in a continuous culture system in which D. vulgaris and G. sulfurreducens are dependent upon the metabolic byproducts of C. cellulolyticum for nutrients. This represents a step towards developing a tractable model ecosystem comprised of members representing the functional groups of a trophic network.

    1993-10-01

    Posters are increasingly recognised as both a method of professional communication and a strategy for learning and assessment in nurse education. Rapid technological developments in health care and the nursing practice environment are generating specific educational needs in relation to the use of technology. There is a move to incorporate within the traditional rational technical focus a broader, more comprehensive understanding of technology, technological equipment and procedures. Technological innovations are an ideal subject matter for poster presentations at the graduate level particularly as broader dimensions such as the impetus for introduction, the research base, the evaluation strategy and the cost can be incorporated. Each poster can become a teaching focus for a student presentation to classmates or other professional forums in order to catalyse discussions of these wider dimensions. A description of the use of posters for these purposes with examples and comments by participants is included.

  1. Drupal as the platform of choice for the Skolr digital meeting poster service

    Science.gov (United States)

    Caron, B. R.

    2011-12-01

    In the Winter of 2011, a small team received funding from the Alfred P. Sloan Foundation to build a pilot digital science meeting poster service (working name: Skolr). Skolr was successfully tested at the summer ESIP Federation meeting in Santa Fe. This talk will outline the issues for building out this service within Drupal. The use of Drupal as the framework/platform for Skolr is expected to facilitate the rapid development of the code base, an ability to then develop a mobile device application for meetings, and improved data-mining and searching. Each year in the USA (and elsewhere), professional academic societies host academic meetings where they provide for a poster session. Collectively, it is not difficult to imagine upwards of a quarter-million posters created, displayed, and discarded in a single year in the U.S. The Skolr service does not propose to replace the current poster activity with a digital activity, the direct person-to-person conversational aspects of these events remain worthwhile. When fully built, Skolr promises to enhance current poster session activities at academic meetings in several ways. For the poster presenter, Skolr offers the following opportunities: 1. Easy upload into an archive where the poster can be viewed by researchers across the globe. 2. Support for a wide range of metadata to improve search-ability. 3. Search and browse capabilities, combined with ratings and other user-generated value added capabilities (tagging and commenting). 4. The poster remains visible and findable for as long as the presenter wishes. 5. The presenter's profile and other information becomes available to those who view her poster, increasing the networking potential. 6. The presenter can activate their own RSS feeds to view similar posters from meetings across the planet and over years. For the meeting host organization, Skolr offers the following opportunities: 1. Social networking for meeting attendees/organizataion members. 2. Poster session

  2. Anti-alcohol posters in Poland, 1945-1989: diverse meanings, uncertain effects.

    Gorsky, Martin; Krajewski-Siuda, Krzysztof; Dutka, Wojciech; Berridge, Virginia

    2010-11-01

    We provide a historical study of the anti-alcohol public health poster in Poland between 1948 and 1990. Our case study illuminates public health policies under communism, with the state as the dominant force in health communication. Poland has a distinctive history of poster art, moving from a Stalinist phase of socialist realism to the diverse styles of the later Polish School. Quantitative and qualitative analysis of 213 posters establishes the major themes and differentiates community approaches, which depict the drinker as a social or political deviant, from those emphasizing individual risk. Medical issues were a minor theme, reflecting public policies geared more toward confinement than treatment. However, Polish School artists used metaphor and ambiguity, and references to the contested cultural symbolism of drink, to complicate and subvert the narrow propaganda intent. Thus, although apparently unsuccessful in restraining overall consumption, these posters offer valuable lessons for policymakers on the use of visual media in health campaigns.

    2015-01-01

    The Royal Society of Chemistry held, to our knowledge, the world's first Twitter conference at 9am on February 5 (th), 2015. The conference was a Twitter-only conference, allowing researchers to upload academic posters as tweets, replacing a physical meeting. This paper reports the details of the event and discusses the outcomes, such as the potential for the use of social media to enhance scientific communication at conferences. In particular, the present work argues that social media outlets such as Twitter broaden audiences, speed up communication, and force clearer and more concise descriptions of a researcher's work. The benefits of poster presentations are also discussed in terms of potential knowledge exchange and networking. This paper serves as a proof-of-concept approach for improving both the public opinion of the poster, and the enhancement of the poster through an innovative online format that some may feel more comfortable with, compared to face-to-face communication.

    2017-10-01

    Academic posters are a common means of disseminating information at conferences. Presentation at conferences is frequently given weight in postgraduate training programme recruitment. Some conferences provide guidance for visual presentation of posters. For the Association of the Study of Medical Education (ASME) Annual Scientific Meeting (ASM) 2015, poster abstract guidance was provided; however, the guidance on poster design was limited to size and orientation. The aim of this study was to investigate academic poster quality at a national medical education conference to identify where standards could be promoted and improved. Presentation at conferences is frequently given weight in postgraduate training programme recruitment METHODS: Six auditors assessed all posters displayed at the ASME ASM (15-17 July 2015) using guidelines based upon a modified checklist for academic posters. Ten criteria were agreed as assessment standards for poster design quality. One-hundred-and-eighty posters were assessed: 29 per cent had appropriate copyright for the materials displayed (n = 52); 41 per cent included suitable contact details (n = 73); 48 per cent (n = 87) had a text to graphic ratio of 50 : 50; 72 per cent (n = 130) met ASME guidance for layout and orientation; 76 per cent (n = 137) had appropriate referencing; 78 per cent showed evidence of proofreading for grammar and spelling (n = 140); 79 per cent (n = 142) were readable at a distance of 2 metres; and 87 per cent used appropriate academic logos (n = 156). There was variability in design quality as assessed by these criteria. We recommend that detailed guidance should be produced and disseminated by the organising conference. This may improve poster quality and aid in the communication of presented material. We aim to re-audit following the production and dissemination of poster presentation guidance. © 2016 John Wiley & Sons Ltd and The Association for the Study of Medical

  13. AAVSO and the International Year of Light (Poster abstract)

    Larsen, K.

    2015-06-01

    (Abstract only) The United Nations General Assembly has officially designated 2015 to be the International Year of Light (IYL). Modeled in part on the earlier International Year of Astronomy (IYA), this cross-disciplinary, international educational and outreach project will celebrate the importance of light in science, technology, cultural heritage, and the arts. It ties in with several important anniversaries, such as the 1000th anniversary of the publication of Ibn Al Haythem's “Book of Optics,” the 150th anniversary of Maxwell's equations of electromagnetism, the centenary of Einstein's General Theory of Relativity, and the 50th anniversary of the discovery of the Cosmic Microwave Background Radiation. Because variable stars are defined as such due to the variability of the light we observe from them, all of the AAVSO programs, regardless of type of variable or instrumentation (eye, DSLR, PEP, or CCD) have natural tie-ins to the study of light. This poster will highlight a number of specific ways that AAVSO members and the organization as a whole can become intimately involved with this unique outreach opportunity.

  14. Jet Vertex Charge Reconstruction Poster for LHCP 2015

    CERN Document Server

    Nektarijevic, Snezana; The ATLAS collaboration

    2015-01-01

    B-jet reconstruction algorithms used so far in ATLAS data analyses do not provide the b-jet charge information, which could potentially play a major role in reducing the combinatorial backgrounds in final states with multiple b-jets. This missing point is addressed by the newly developed JetVertexCharge (JVC) algorithm presented in this poster. Inspired by the decay chain of B-hadrons, the JVC algorithm provides a multi-variate b-jet charge estimate relying on tracks, displaced vertices and muons contained in the jet. In this algorithm, the established concept of estimating jet charge as a transverse momentum weighted sum of track charges is used to reconstruct the charge of the jet as whole, as well as the charges of up to two displaced vertices in the jet, using the corresponding sets of associated tracks. The charge of the associated muon is interpreted as the same-sign or opposite-sign relative to the b-jet charge, according to its transverse momentum and geometrical match to vertices. Jets are divided in...

    2012-06-01

    This was a poster displayed at the Symposium. Advances on previous high throughput screening of biomass recalcitrance methods have resulted in improved conversion and replicate precision. Changes in plate reactor metallurgy, improved preparation of control biomass, species-specific pretreatment conditions, and enzymatic hydrolysis parameters have reduced overall coefficients of variation to an average of 6% for sample replicates. These method changes have improved plate-to-plate variation of control biomass recalcitrance and improved confidence in sugar release differences between samples. With smaller errors plant researchers can have a higher degree of assurance more low recalcitrance candidates can be identified. Significant changes in plate reactor, control biomass preparation, pretreatment conditions and enzyme have significantly reduced sample and control replicate variability. Reactor plate metallurgy significantly impacts sugar release aluminum leaching into reaction during pretreatment degrades sugars and inhibits enzyme activity. Removal of starch and extractives significantly decreases control biomass variability. New enzyme formulations give more consistent and higher conversion levels, however required re-optimization for switchgrass. Pretreatment time and temperature (severity) should be adjusted to specific biomass types i.e. woody vs. herbaceous. Desalting of enzyme preps to remove low molecular weight stabilizers and improved conversion levels likely due to water activity impacts on enzyme structure and substrate interactions not attempted here due to need to continually desalt and validate precise enzyme concentration and activity.

    This poster presents the hot cell facility which is being constructed as part of the SUSEN project at the Rez research center (Czech Republic). Within this project a new complex of 10 hot cells and one semi-hot cell will be built. There will be 8 gamma hot cells and 2 alpha hot cells. In each hot cell a hermetic, removable box made of stainless steel will home different type of devices. The hot cells and semi hot cell will be equipped with devices for processing samples (cutting, welding, drilling, machining) as well as equipment for testing (sample preparation area, stress testing machine, fatigue machine, electromechanical creep machine, high frequency resonance pulsator...) and equipment for studying material microstructure (nano-indenter with nano-scratch tester and scanning electron microscope). An autoclave with water loop, installed in a cell will allow mechanical testing in control environment of water, pressure and temperature. A scheme shows the equipment of each cell. This hot laboratory will be able to cover all the process to study radioactive materials: receiving the material, the preparation of the samples, mechanical testing and microstructure observation. Our hot cells will be close to the research nuclear reactor LVR-15 and new irradiation facility (high irradiation by cobalt source) is planned to be built within the SUSEN project

    Full Text Available A Pre-design process in studio design class includes observation phase, analysis and programming, a directed process of searching and recording information. Based on an early observation, currently pre-design activities in class or studio often has been less optimal due to the low of students performance and the creativities. This causes the output generated from pre-design process was not maximized while undocumented or do not have a good track records. This paper aims to explore the use of posters as a creative ideas in the documentation of of pre-design stage. This is a class-action research as the result of the development of pre-design activities with inquiry methods using the poster as a medium track record in architectural design studio. Research methods include observation and assessment pre-design student outcomes, and questionnaire. Poster outcomes observation were ratings based on several criterias. The questionnnaires tested the posters feasibility in improving the performance and outcomes based on the process and student experiences. Because it is class-action reasearch, this study is limited to the studio class where the author conducted lectures and studio guidance. The results showed an increase in the performance of students in search of matter, observations, material analysis, as well as programming in the use of posters as track record media. In addition, students were satisfied and more creatively visualize their ideas in the pr e-design phase by using the poster media

    Clostridium septicum ( C. septicum ) aortitis is a rare condition frequently associated with colon adenocarcinoma and carries a poor prognosis. We report the case of a 66-year-old man who presented with abdominal pain, blood in the stool, fever and chills. Laboratory tests were significant for leukocytosis and microcytic anemia. Abdominal imaging revealed a right colon mass and aortitis. Colonoscopy confirmed the right colon mass and also discovered a rectal mass, both adenocarcinomas. Treatment consisted of antibiotics, aortic repair, right hemi-colectomy and later trans-anal excision of the rectal mass. Blood cultures and the aortic specimen grew C. septicum .

  4. Probiotics and Antibiotic-Associated Diarrhea and Clostridium difficile Infection

    Science.gov (United States)

    Surawicz, Christina M.

    Diarrhea is a common side effect of antibiotics. Antibiotics can cause diarrhea in 5-25% of individuals who take them but its occurrence is unpredictable. Diarrhea due to antibiotics is called antibiotic-associated diarrhea (AAD). Diarrhea may be mild and resolve when antibiotics are discontinued, or it may be more severe. The most severe form of AAD is caused by overgrowth of Clostridium difficile which can cause severe diarrhea, colitis, pseudomembranous colitis, or even fatal toxic megacolon. Rates of diarrhea vary with the specific antibiotic as well as with the individual susceptibility.

    2014-01-01

    Full Text Available Although classically pseudomembranous colitis is caused by Clostridium difficile, it can result from several etiologies. Certain medications, chemical injury, collagenous colitis, inflammatory bowel disease, ischemia, and other infectious pathogens can reportedly cause mucosal injury and subsequent pseudomembrane formation. We present the case of a middle-aged woman with vascular disease who was incorrectly diagnosed with refractory C. difficile infection due to the presence of pseudomembranes. Further imaging, endoscopy, and careful histopathology review revealed chronic ischemia as the cause of her pseudomembranous colitis and diarrhea. This case highlights the need for gastroenterologists to consider non-C. difficile etiologies when diagnosing pseudomembranous colitis.

    Full Text Available Clostridium difficile is a frequent cause of antibiotic-associated diarrhea in adults and older children. However, as many as 80% of infants can be asymptomatically colonized. The reasons for this have not been well established but are believed to be due to differences in toxin receptors or toxin internalization. Determining which children who test positive for C. difficile warrant treatment is exceedingly difficult, especially in the setting of increased rates of detection and the rising risk of disease in children lacking classic risk factors for C. difficile.

    2004-12-01

    A geologist/educator and a research curator of the New Mexico Museum of Natural History and Science and a geologist/middle school teacher from the Albuquerque Public Schools have created an educational poster that uses the landscape around Albuquerque in order to teach fundamental geoscience concepts. "Albuquerque's Geoscape" is based on the innovative "Geoscape Vancouver" produced by the Geological Survey of Canada. The Albuquerque poster required four years of development including the creation of unique graphics and text, evaluations, and reviews by geologists and classroom educators. The poster content is aligned with state and national science standards at the middle school level and can be modified by teachers from K-12. All information that a teacher might need in order to teach a thematic unit on major geological topics is included in the poster, and linked to the local landscape. An accompanying web site for teachers includes additional materials. The initial funding for the project was an Intel Innovations in Teaching Grant, in the amount of 3K, awarded to Newsom. Museum in-house resources in science, education and graphics were utilized in the poster design and development. Funding for printing required small contributions from many local and regional organizations supporting science education. These contributors included Sandia National Lab, Rocky Mountain Section AAPG Foundation, New Mexico Academy of Science, ExxonMobile Volunteer Involvement Grant, Federal Bureau of Land Management, Albuquerque Rotary Club and Albuquerque Geological Society. Printing at-cost through a local company produced a poster on high quality paper at low cost. An initial printing of 5000 copies has enabled the Museum to offer the poster free of charge to all greater Albuquerque area K-12 teachers. In addition, the poster is on sale to the general public at the museum store. The response by classroom educators, local geologists, and the general public has been enthusiastic. The

    The anaerobic gastrointestinal pathogen Clostridium difficile must form a metabolically dormant spore to survive in oxygenic environments and be transmitted from host to host. The regulatory factors by which C. difficile initiates and controls the early stages of sporulation in C. difficile are not highly conserved in other Clostridium or Bacillus species. Here, we investigated the role of two conserved oligopeptide permeases, Opp and App, in the regulation of sporulation in C. difficile. These permeases are known to positively affect sporulation in Bacillus species through the import of sporulation-specific quorum-sensing peptides. In contrast to other spore-forming bacteria, we discovered that inactivating these permeases in C. difficile resulted in the earlier expression of early sporulation genes and increased sporulation in vitro. Furthermore, disruption of opp and app resulted in greater virulence and increased the amounts of spores recovered from feces in the hamster model of C. difficile infection. Our data suggest that Opp and App indirectly inhibit sporulation, likely through the activities of the transcriptional regulator SinR and its inhibitor, SinI. Taken together, these results indicate that the Opp and App transporters serve a different function in controlling sporulation and virulence in C. difficile than in Bacillus subtilis and suggest that nutrient availability plays a significant role in pathogenesis and sporulation in vivo. This study suggests a link between the nutritional status of the environment and sporulation initiation in C. difficile. Copyright © 2014, American Society for Microbiology. All Rights Reserved.

Risk factors primarily associated with Peyronie's disease include Dupuytren's contracture, penile trauma, and family history. A variety of treatment strategies have been utilized, including oral and topical agents, electromotive drug administration, intralesional injections, extracorporeal shockwave therapy, penile traction, and surgery. However, most of these strategies are ineffective, with surgery being the only definitive treatment. Collagenase clostridium histolyticum is a newly US Food and Drug Administration-approved agent for intralesional injection. It is thought to downregulate many of the disease-related genes, cytokines, and growth factors and degrade collagen fibers. It also suppresses cell attachment, spreading, and proliferation. Collagenase clostridium histolyticum has been clinically proven to be a safe and effective therapeutic option, demonstrating decreases in penile curvature and plaque consistency, as well as increases in patient satisfaction. During clinical evaluation, the Peyronie's Disease Questionnaire was validated as an effective tool for assessing treatment outcomes.

    2001-01-01

    The toxigenic strains of Clostridium botulinum produce seven serologically distinct types of neurotoxins labeled A - G (EC 3.4.24.69), while Clostridium tetani produces tetanus neurotoxin (EC 3.4.24.68). Botulinum and tetanus neurotoxins (BoNTs and TeNT) are produced as single inactive chains of molecular mass of approximately 150 kDa. Most of these neurotoxins are released after being cleaved into two chains, a heavy chain (HI) of 100 kDa and a light chain (L) of 50 kDa held together by an interchain disulfide bond, by tissue proteinases. BoNT/E is released as a single chain but cleaved by host proteinases[1]. Clostvidium botulinum neurotoxins are extremely poisonous proteins with their LD(sub 50) for humans in the range of 0.1 - 1 ng kg(sup -1)[2]. Botulinum neurotoxins are responsible for neuroparalytic syndromes of botulism characterized by serious neurological disorders and flaccid paralysis. BoNTs block the release of acetylcholine at the neuromuscular junction causing flaccid paralysis while TeNT blocks the release of neurotransmitters like glycine and(gamma)-aminobutyric acid (GABA) in the inhibitory interneurons of the spinal cord resulting in spastic paralysis. In spite of different clinical symptoms, their aetiological agents intoxicate neuronal cells in the same way and these toxins have similar structural organization[3

    Full Text Available Introduction: Clostridium difficile is the most important definable cause of healthcare acquired diarrhea. Recommended treatments for Clostridium difficile infection (CDI are metronidazole, oral vancomycin and fidaxomicin (a new narrow spectrum macrocyclic antibiotic. Aim: The aim of this investigation was to review the treatment of CDI in Iran. Method: 1600 medical records and prescriptions were scrutinized for patients complaining of diarrhea, colitis and gastroenteritis. The therapeutic route was investigated in each individual case bearing in mind the medical and medication history as well as other co-morbidities. Results: The selection of antibiotic by many medical practitioners for the treatment of diarrhea, colitis and gastroenteritis were inappropriate and random. In most cases the chosen antibiotic, can itself be associated with initiation or worsening of CDI. Conclusion: The needs for antimicrobial stewardship program to preserve the effectiveness of current available therapies are strongly recommended. This program must focus on the overall reduction of inappropriate antibiotic prescribing and ultimately on enforcing the adherence to the reputable antibacterial guidelines.

    Clostridium difficile infection (CDI) is a major healthcare-associated infection that causes significant morbidity and an economic impact in the United States. In this review, we provide an overview of Clostridium difficile infection in solid organ transplant recipients with an emphasis on recent literature. C. difficile in solid organ transplant population has unique risk factors. Fecal microbiota transplantation has shown favorable results in treatment of recurrent C. difficile in this population. Preliminary data from animal studies suggests excellent efficacy with immunization against C. difficile toxins. Over the last decade, number of individuals receiving solid organ transplants has increased exponentially making peri-transplant complications a common occurrence.C. difficile is a frequent cause of morbidity in solid organ transplant recipients. Early and accurate diagnosis of C. difficile requires a stepwise approach. Differentiating between asymptomatic carriage and infection is a diagnostic challenge. Microbial diversity is inversely proportional to risk of C. difficile infection. Antimicrobial stewardship programs help to retain microbial diversity in individuals susceptible to CDI. Recurrent or relapsing C. difficile infection require fecal microbiota transplantation for definitive cure.

    Full Text Available Clostridium perfringens is an anaerobic gram positive rod that is found in normal vaginal and cervical flora in 1–10% of healthy women. Uterine infection with Clostridium perfringens is seen rarely but is often related to underlying uterine pathology and can progress quickly to sepsis. Early recognition of sepsis, prompt treatment with antibiotics, and source control with surgical management allow for optimal chance of recovery. We present a case of a postmenopausal woman who presented with sepsis, vaginal bleeding, and back pain who was found to have Clostridium perfringens infection in the setting of undifferentiated uterine sarcoma.

  1. What is the evidence that poster presentations are effective in promoting knowledge transfer? A state of the art review.

    Science.gov (United States)

    Ilic, Dragan; Rowe, Nicholas

    2013-03-01

    Poster presentations are a common form of presenting health information at conferences and in the community. Anecdotal evidence within the discipline indicates that health information framed in a poster presentation may be an effective method of knowledge transfer. A state of the art review of the literature was performed to determine the effectiveness of poster presentations on knowledge transfer. Electronic searches of various electronic databases were performed for studies published until 2012. Studies were eligible for inclusion if they provided empirical data on the effectiveness of poster presentations on changes in participant knowledge, attitude or behaviour. A total of 51 studies were identified through the database searches, of which 15 met the inclusion criteria. No study evaluated the effectiveness of posters in comparison with other educational interventions. Most studies utilised a before/after methodology, with the common conclusion that posters elicit greatest effectiveness in knowledge transfer when integrated with other educational modalities. The poster presentation is a commonly used format for communicating information within the academic and public health fields. Evidence from well-designed studies comparing posters to other educational modalities is required to establish an evidence base on the effectiveness of utilising posters in achieving knowledge transfer. © 2013 The authors.

    Patients who visit online support groups benefit in various ways. Results of our earlier study indicated that participation in online support groups had a profound effect on the participants' feelings of "being empowered." However, most studies of online patient support groups have focused on the members of these groups who actively contribute by sending postings (posters). Thus far, little is known about the impact for "lurkers" (ie, those who do not actively participate by sending postings). In the present study, we explored if lurkers in online patient support groups profit to the same extent as posters do. We searched the Internet with the search engine Google to identify all Dutch online support groups for patients with breast cancer, fibromyalgia, and arthritis. Invitations to complete an online survey were sent out by the owners of 19 groups. In the online questionnaire, we asked questions about demographic and health characteristics, use of and satisfaction with the online support group, empowering processes, and empowering outcomes. The online questionnaire was completed by 528 individuals, of which 109 (21%) identified themselves as lurkers. Lurkers (mean age 47 years) were slightly older than active participants (mean age 43 years, P = .002), had a shorter disease history (time since diagnosis 3.7 years vs 5.4 years, P = .001), and reported lower mental well-being (SF 12 subscore 37.7 vs 40.5, P = .004). No significant differences were found in other demographic variables. Posters indicated visiting the online support groups significantly more often for social reasons, such as curiosity about how other members were doing, to enjoy themselves, as a part of their daily routine (all P posters did not differ in their information-related reasons for visiting the online support group. Lurkers were significantly less satisfied with the online support group compared to posters (P posters. However, lurkers did not differ significantly from posters with regard to

    Web 2.0 has improved interactions among peers on the Internet, especially for the many online patient communities that have emerged over the past decades. Online communities are said to be particularly beneficial peer support resources for patients with breast cancer. However, most studies of online patient communities have focused on those members who post actively (posters), even though there are many members who participate without posting (lurkers). In addition, little attention has been paid to the usage of online communities among non-English-speaking patients. The present study explored the differences in peer support received by lurkers and posters in online breast cancer communities. It also examined the effects of such support on both groups' mental health. We conducted an exploratory, descriptive, cross-sectional, Web-based survey among members of four Japanese online breast cancer communities. In an online questionnaire, we asked questions regarding sociodemographics, disease-related characteristics, mental health, participation in online communities, and peer support received from those communities. Of the 465 people who accessed the questionnaire, 253 completed it. Of the respondents, 113/220 (51.4%) were lurkers. There was no significant difference between lurkers and posters with regard to sociodemographic variables. About half of the posters had been given a diagnosis of breast cancer less than a year previously, which was a significantly shorter period than that of the lurkers (P = .02). The 5 support functions extracted by factor analysis were the same for both posters and lurkers. These were emotional support/helper therapy, emotional expression, conflict, advice, and insight/universality. When the support scores were calculated, insight/universality scored highest for both posters and lurkers, with scores that were not significantly different between the two groups. Among the 5 support scores, emotional support/helper therapy and emotional

    Full Text Available In the past few decades poster has imposed itself as a significant means of communicating messages, views and thoughts on current social and cultural life issues of the environment it originates in. It has tried to confirm by its rhetoric the engaged content in its own logical interrelation of the media: character/speech-sign-thought/message, placing emphasis on its genre feature: cultural poster. As the issue here is the means of development of ideas, critical thinking and social consciousness, in other words, the mediation of cultural values, I will try to shed some light on the phenomenon of cultural poster and to pinpoint its position among contemporary theoretical practices, as well as to point the ranges of design which have been created at the intersection of its artistic orientation and new commercial reality. One of the interesting and worthy prac­tices, Novi Sad Cultural Poster, originated in the sixties and reached its stellar status in the seventies and eighties, and in the past few decades its long tradition has yielded new names and exemplary works of world class. Novi Sad Cultural Poster can be viewed as a stylistically unique practice regardless of the diversity of artistic and design prin­ciples of its practitioners, their age or ways of thinking. Despite the attempts of some designers and professional circles, it still lacks appropriate methodological research and evaluation.

  5. A comparison of lurkers and posters within infertility online support groups.

    Current research shows that online support groups can offer people affected by infertility a unique and valuable source of social support. However, to date most research has focused on the experiences of people who post messages to online infertility support groups; in comparison, little is known about how "lurkers" (i.e., those individuals who read messages but do not post messages) use and benefit from online infertility support groups. The purpose of the present study was to compare the use and experience of online infertility support groups between lurkers and posters. A total of 295 participants who were recruited from several online infertility support groups completed an online questionnaire containing questions about their use and experience of online support groups and measures of loneliness, social support, marital satisfaction, and perceived infertility-related stress. Differences between lurkers and posters were analyzed using Mann-Whitney U and χ or Fisher exact tests. Results revealed that compared with posters, lurkers visited the online support groups less often and scored significantly lower in overall satisfaction with the online support group. However, both lurkers and posters reported gaining a range of unique benefits from access to an online support group. Furthermore, there were no significant differences in loneliness, social support, infertility-related stress, and marital satisfaction between lurkers and posters. These findings suggest that reading messages posted to online support groups may be as beneficial as interacting with the group.

    2015-01-01

    Full Text Available This paper looks at some similarities and differences between propaganda art used by Germany and the United States during World War I. The first section briefly looks at aesthetic theory and addresses the philosophical question of whether war propaganda posters are, in fact, ‘art’ at all. Then images of various posters that were popular and widely published by both nations are shown and discussed. This paper concludes that while there are many thematic similarities between the posters used by both sides, there are also some important differences. The most obvious difference between the German and American propaganda art was in regard to the overall tone of the posters and the colors used in the presentation. The images used have been downloaded from a reputable website that depicts reproductions of the posters that were used during WW1. Understanding the nature of the propaganda used by each side can help shed light on the attitudes and sentiments towards the war held by political elites and citizens alike.

  13. The potential economic value of screening hospital admissions for Clostridium difficile.

    2012-11-01

    Asymptomatic Clostridium difficile carriage has a prevalence reported as high as 51-85 %; with up to 84 % of incident hospital-acquired infections linked to carriers. Accurately identifying carriers may limit the spread of Clostridium difficile. Since new technology adoption depends heavily on its economic value, we developed an analytic simulation model to determine the cost-effectiveness screening hospital admissions for Clostridium difficile from the hospital and third party payer perspectives. Isolation precautions were applied to patients testing positive, preventing transmission. Sensitivity analyses varied Clostridium difficile colonization rate, infection probability among secondary cases, contact isolation compliance, and screening cost. Screening was cost-effective (i.e., incremental cost-effectiveness ratio [ICER] ≤ $50,000/QALY) for every scenario tested; all ICER values were ≤ $256/QALY. Screening was economically dominant (i.e., saved costs and provided health benefits) with a ≥10.3 % colonization rate and ≥5.88 % infection probability when contact isolation compliance was ≥25 % (hospital perspective). Under some conditions screening led to cost savings per case averted (range, $53-272). Clostridium difficile screening, coupled with isolation precautions, may be a cost-effective intervention to hospitals and third party payers, based on prevalence. Limiting Clostridium difficile transmission can reduce the number of infections, thereby reducing its economic burden to the healthcare system.

    Street, Annette F

    2004-12-01

    This paper examines two full-page A3 poster advertisements in mass magazines produced at two time points over a 60-year period depicting smoking and its effects, with particular relation to lung cancer. Each poster represents the social and cultural milieu of its time. The writings of Foucault are used to explore the disciplinary technologies of sign systems as depicted in the two posters. The relationships between government, tobacco companies and drug companies and the technologies of production are examined with regard to the development of smoking cessation strategies. The technologies of power are associated with the constructions of risk and lifestyles. The technologies of the self locate smokers as culpable subjects responsible for their individual health. Finally, the meshing of these technologies places the doctor in the frame as "authoritative knower" and representative of expert systems.

  16. What impact do posters have on academic knowledge transfer? A pilot survey on author attitudes and experiences

    Full Text Available Abstract Background Research knowledge is commonly facilitated at conferences via oral presentations, poster presentations and workshops. Current literature exploring the efficacy of academic posters is however limited. The purpose of this initial study was to explore the perceptions of academic poster presentation, together with its benefits and limitations as an effective mechanism for academic knowledge transfer and contribute to the available academic data. Methods A survey was distributed to 88 delegates who presented academic posters at two Releasing Research and Enterprise Potential conferences in June 2007 and June 2008 at Bournemouth University. This survey addressed attitude and opinion items, together with their general experiences of poster presentations. Descriptive statistics were performed on the responses. Results A 39% return was achieved with the majority of respondents believing that posters are a good medium for transferring knowledge and a valid form of academic publication. Visual appeal was cited as more influential than subject content, with 94% agreeing that poster imagery is most likely to draw viewer's attention. Respondents also believed that posters must be accompanied by their author in order to effectively communicate the academic content. Conclusion This pilot study is the first to explore perceptions of the academic poster as a medium for knowledge transfer. Given that academic posters rely heavily on visual appeal and direct author interaction, the medium requires greater flexibility in their design to promote effective knowledge transfer. This paper introduces the concept of the IT-based 'MediaPoster' so as to address the issues raised within published literature and subsequently enhance knowledge-transfer within the field of academic medicine.

    Research knowledge is commonly facilitated at conferences via oral presentations, poster presentations and workshops. Current literature exploring the efficacy of academic posters is however limited. The purpose of this initial study was to explore the perceptions of academic poster presentation, together with its benefits and limitations as an effective mechanism for academic knowledge transfer and contribute to the available academic data. A survey was distributed to 88 delegates who presented academic posters at two Releasing Research and Enterprise Potential conferences in June 2007 and June 2008 at Bournemouth University. This survey addressed attitude and opinion items, together with their general experiences of poster presentations. Descriptive statistics were performed on the responses. A 39% return was achieved with the majority of respondents believing that posters are a good medium for transferring knowledge and a valid form of academic publication. Visual appeal was cited as more influential than subject content, with 94% agreeing that poster imagery is most likely to draw viewer's attention. Respondents also believed that posters must be accompanied by their author in order to effectively communicate the academic content. This pilot study is the first to explore perceptions of the academic poster as a medium for knowledge transfer. Given that academic posters rely heavily on visual appeal and direct author interaction, the medium requires greater flexibility in their design to promote effective knowledge transfer. This paper introduces the concept of the IT-based 'MediaPoster' so as to address the issues raised within published literature and subsequently enhance knowledge-transfer within the field of academic medicine.

    Zoonoses are infections or diseases that can be transmitted between animals and humans through direct contact, close proximity or the environment. Clostridium difficile is ubiquitous in the environment, and the bacterium is able to colonise the intestinal tract of both animals and humans. Since domestic and food animals frequently test positive for toxigenic C. difficile, even without showing any signs of disease, it seems plausible that C. difficile could be zoonotic. Therefore, animals could play an essential role as carriers of the bacterium. In addition, the presence of the spores in different meats, fish, fruits and vegetables suggests a risk of foodborne transmission. This review summarises the current available data on C. difficile in animals and foods, from when the bacterium was first described up to the present.

    Basis on the results of the research was concluded that microwave radiation (700W and 900W shows disintegration action expressed in COD value in the supernatant increase: 12 times increase value of COD with power 700W and 13 times for 900W radiation power. Electromagnetic wave contributed to partial higienisation of surplus activated sludge. The number of Clostridium perfringens decrease about 52% and 56% during the 120s of higienisation process with power 700W and 900W, respectively. Reduction of the overall number of bacteria under the influence of microwave radiation was 42% and 51% (respectively for 700W and 900W, and sticks from the family Enterobacteriaceae from 54% to 70% depending on the power of radiation, the time of operation and biochemical properties.

    Clostridium difficile is a gastrointestinal pathogen but how the bacterium colonises this niche is still little understood. Sortase enzymes covalently attach specific bacterial proteins to the peptidoglycan cell wall and are often involved in colonisation by pathogens. Here we show C. difficile proteins CD2537 and CD3392 are functional substrates of sortase SrtB. Through manipulation of the C-terminal regions of these proteins we show the SPKTG motif is essential for covalent attachment to the cell wall. Two additional putative substrates, CD0183 which contains an SPSTG motif, and CD2768 which contains an SPQTG motif, are not cleaved or anchored to the cell wall by sortase. Finally, using an in vivo asymmetric cleavage assay, we show that despite containing a conserved SPKTG motif, in the absence of SrtB these proteins are localised to disparate cellular compartments.

    The Skylab Food System presented unique microbiological problems because food was warmed in null-gravity and because the heat source was limited to 69.4 C (to prevent boiling in null-gravity). For these reasons, the foods were manufactured using critical control point techniques of quality control coupled with appropriate hazard analyses. One of these hazard analyses evaluated the threat from Clostridium perfringens. Samples of food were inoculated with C. perfringens and incubated for 2 h at temperatures ranging from 25 to 55 C. Generation times were determined for the foods at various temperatures. Results of these tests were evaluated taking into consideration: food-borne disease epidemiology, the Skylab food manufacturing procedures, and the performance requirements of the Skylab Food System. Based on this hazard analysis, a limit for C. perfringens of 100/g was established for Skylab foods.

    Clostridium indolis DSM 755(T) is a bacterium commonly found in soils and the feces of birds and mammals. Despite its prevalence, little is known about the ecology or physiology of this species. However, close relatives, C. saccharolyticum and C. hathewayi, have demonstrated interesting metabolic potentials related to plant degradation and human health. The genome of C. indolis DSM 755(T) reveals an abundance of genes in functional groups associated with the transport and utilization of carbohydrates, as well as citrate, lactate, and aromatics. Ecologically relevant gene clusters related to nitrogen fixation and a unique type of bacterial microcompartment, the CoAT BMC, are also detected. Our genome analysis suggests hypotheses to be tested in future culture based work to better understand the physiology of this poorly described species.

    Full Text Available We present the case of a 58-year-old man who underwent urgent blowhole colostomy for toxic megacolon (TM secondary to Clostridium difficile infection (CDI. This infection occurred under antibiotic coverage with amoxicillin-clavulanic acid, four days after laparoscopic sigmoidectomy in our hospital. Although prospective clinical research regarding the surgical management of TM is lacking, decompressive procedures like blowhole colostomy are reported to carry a high risk of postoperative morbidity and mortality and are widely regarded as obsolete. Subtotal or total colectomy with end ileostomy is currently considered the procedure of choice. After presenting our case, we discuss the literature available on the subject to argue that the scarce evidence on the optimal surgical treatment for TM is primarily based on TM associated with inflammatory bowel diseases (IBD and that there might be a rationale for considering minimally invasive procedures like blowhole colostomy for CDI-associated TM.

    In the presence of 100 micrograms of caffeine per ml or 200 micrograms of theobromine per ml, sporulation of Clostridium perfringens NCTC 8679 rose from less than 1 to 80 or 85%. Enterotoxin concentration increased from undetectable levels to 450 micrograms/mg of cell extract protein. Heat-resistant spore levels increased from less than 1,000 to between 1 X 10(7) and 2 X 10(7)/ml. These effects were partially reversible by the addition of adenosine or thymidine. In the case of NCTC 8238, caffeine and theobromine caused a three- to fourfold increase in the percentages of cells possessing refractile spores and a similar increase in enterotoxin concentration. Heat-resistant spore levels, however, were unaffected. Inosine was ineffective in promoting sporulation in NCTC 8679. PMID:6271685

    Over the recent decades, Clostridium difficile infection (CDI) has emerged as a global public health threat. Despite growing attention, C. difficile remains a poorly understood pathogen, however, the exquisite sensitivity offered by next generation sequencing (NGS) technology has enabled analysis of the genome of C. difficile, giving us access to massive genomic data on factors such as virulence, evolution, and genetic relatedness within C. difficile groups. NGS has also demonstrated excellence in investigations of outbreaks and disease transmission, in both small and large-scale applications. This review summarizes the molecular epidemiology, evolution, and phylogeny of C. difficile, one of the most important pathogens worldwide in the current antibiotic resistance era.

    Clostridium difficile infection (CDI) is the leading cause of hospital-acquired diarrhea and is associated with a considerable health and cost burden. However, there is still not a clear consensus on the best laboratory diagnosis approach and a wide variation of testing methods and strategies can be encountered. We aim to review the most practical aspects of CDI diagnosis providing our own view on how to optimize CDI diagnosis. Expert commentary: Laboratory diagnosis in search of C. difficile toxins should be applied to all fecal diarrheic samples reaching the microbiology laboratory in patients > 2 years old, with or without classic risk factors for CDI. Detection of toxins either directly in the fecal sample or in the bacteria isolated in culture confirm CDI in the proper clinical setting. Nuclear Acid Assay techniques (NAAT) allow to speed up the process with epidemiological and therapeutic consequences.

    The Gram-positive anaerobic bacterium Clostridium difficile produces toxins A and B, which can cause a spectrum of diseases from pseudomembranous colitis to C. difficile-associated diarrhea. A limited number of C. difficile strains also produce a binary toxin that exhibits ADP ribosyltransferase activity. Here, the structure and the mechanism of action of these toxins as well as their role in disease are reviewed. Nosocomial C. difficile infection is often contracted in hospital when patients treated with antibiotics suffer a disturbance in normal gut microflora. C. difficile spores can persist on dry, inanimate surface for months. Metronidazole and oral vancomycin are clinically used for treatment of C. difficile infection but clinical failure and concern about promotion of resistance are motivating the search for novel non-antibiotic therapeutics. Methods for controlling both toxins and spores, replacing gut microflora by probiotics or fecal transplant, and killing bacteria in the anaerobic gut by photodynamic therapy are discussed.

    In recent years, Clostridium difficile infection (CDI) has become a global public health threat associated with increased morbidity, mortality, and economic burden, all of which are exacerbated with disease recurrence. Current guidelines informing treatment decisions are largely based on definitions of disease severity at diagnosis, with subjective components not well delineated across treatment algorithms and clinical trials. Furthermore, there is little evidence linking severity at onset to outcome. However, reducing the risk of recurrence may offer both a better outcome for the individual and decreased downstream economic impact. The authors present data supporting the opinion that patients deemed at low risk for recurrence should receive vancomycin (or metronidazole when cost is an issue), while those at higher risk of recurrence would benefit from fidaxomicin treatment. Although further prospective studies are needed, choosing treatment with the goal of preventing recurrent CDI may offer a better guide than disease severity. © 2016 Pharmacotherapy Publications, Inc.

    To determine the possible utility of pomegranate extract in the management or prevention of Clostridium difficile infections or colonization. The activity of pomegranate was tested against 29 clinical C. difficile isolates using the Clinical and Laboratory Standards Institute-approved agar dilution technique. Total phenolics content of the pomegranate extract was determined by Folin-Ciocalteau colorimetric method and final concentrations of 6.25 to 400 μg/mL gallic acid equivalent were achieved in the agar. All strains had MICs at 12.5 to 25 mg/mL gallic acid equivalent range. Our results suggest antimicrobial in vitro activity for pomegranate extract against toxigenic C. difficile. Pomegranate extract may be a useful contributor to the management and prevention of C. difficile disease or colonization. Copyright © 2014 Elsevier Inc. All rights reserved.

    This study was undertaken to examine phenotypic and genetic features of strains preliminary classified as Clostridium botulinum species. The phenotypic characteristics were assessed with different culture media and biochemical tests. The genetic characterization included detection of botulinum toxin genes by PCR and macrorestriction analysis with SmaI, XhoI and SacII by PFGE (Pulsed-field Gel Electrophoresis). Despite similar biochemical properties of all analysed strains, only 47% of them contained genes determining toxicity specific to C. botulinum species. The most valuable differentiation of C. botulinum and C. botulinum-like strains was obtained after SmaI digestion. The highest affinity was observed among C. botulinum type B profiles which was even up to 100%. It was found 100% of affinity between C. botulinum and C. botulinum-like strains, however, the similarity among C. botulinum and C. botulinum-like was generally lower than 80%.

    Clostridium difficile infection (CDI) is increasingly prevalent, dangerous and challenging to prevent and manage. Despite intense national and international attention the incidence of primary and of recurrent CDI (PCDI and RCDI, respectively) have risen rapidly throughout the past decade. Of major concern is the increase in cases of RCDI resulting in substantial morbidity, morality and economic burden. RCDI management remains challenging as there is no uniformly effective therapy, no firm consensus on optimal treatment, and reliable data regarding RCDI-specific treatment options is scant. Novel therapeutic strategies are critically needed to rapidly, accurately, and effectively identify and treat patients with, or at-risk for, RCDI. In this review we consider the factors implicated in the epidemiology, pathogenesis and clinical presentation of RCDI, evaluate current management options for RCDI and explore novel and emerging therapies.

    2015-02-01

    Full Text Available Clostridium perfringens beta-toxin is a key mediator of necrotizing enterocolitis and enterotoxemia. It is a pore-forming toxin (PFT that exerts cytotoxic effect. Experimental investigation using piglet and rabbit intestinal loop models and a mouse infection model apparently showed that beta-toxin is the important pathogenic factor of the organisms. The toxin caused the swelling and disruption of HL-60 cells and formed a functional pore in the lipid raft microdomains of sensitive cells. These findings represent significant progress in the characterization of the toxin with knowledge on its biological features, mechanism of action and structure-function having been accumulated. Our aims here are to review the current progresses in our comprehension of the virulence of C. perfringens type C and the character, biological feature and structure-function of beta-toxin.

    Poster presentations are an important part of presenting scientific techniques and represent an integral part of conferences and meetings. Traditionally, paper format is used; however, in recent years electronic posters and other methods, such as incorporating a DVD player as part of a poster, have been successfully used. We describe and demonstrate the use of an augmented reality application for smartphones and tablets as a potential future addition to the presentation of scientific work and surgical techniques in poster format. This method allows the audience to view surgical techniques and research as 3D animation or video by using a trigger image in a poster/journal/text book via their smart device. The author used the free Aurasma© application available on both iOS and Android 2.2 and higher platforms from iTunes App Store and Google Play. Once installed, any user with a 3G or WiFi connection via a smart phone or tablet can subscribe to the Medical Illustration channel for free. The user can then scan the trigger image placed on a poster with a mobile device to view videos, animations or 3D data. Further interaction can direct the user to a website for more content. The author has trialled this method at a regional burns and plastic surgery centre and found it to be highly effective. The use of this novel method adds a new dimension to the presentation of scientific work at surgical and medical conferences and as part of journals and textbooks by permitting users to view scientific data and techniques on mobile devices as videos or as three dimensional environments at their own leisure.

    The Virtual Poster Session (VPS) of the Association of Polar Early Career Scientists (APECS) was developed by early career scientists as an online tool for communicating and discussing science and research beyond the four walls of a conference venue. Poster sessions often are the backbone of a conference where especially early career scientists get a chance to communicate their research, discuss ideas, data, and scientific problems with their peers and senior scientists. There, they can hone their 'elevator pitch', discussion skills and presentation skills. APECS has taken the poster session one step further and created the VPS - the same idea but independent from conferences, travel, and location. All that is needed is a computer with internet access. Instead of letting their posters collect dust on the computer's hard drive, scientists can now upload them to the APECS website. There, others have the continuous opportunity to comment, give feedback and discuss the work. Currently, about 200 posters are accessible contributed by authors and co-authors from 34 countries. Since January 2010, researchers can discuss their poster with a broad international audience including fellow researchers, community members, potential colleagues and collaborators, policy makers and educators during monthly conference calls via an internet platform. Recordings of the calls are available online afterwards. Calls so far have included topical sessions on e.g. marine biology, glaciology, or social sciences, and interdisciplinary calls on Arctic sciences or polar research activities in a specific country, e.g. India or Romania. They attracted audiences of scientists at all career stages and from all continents, with on average about 15 persons participating per call. Online tools like the VPS open up new ways for creating collaborations and new research ideas and sharing different methodologies for future projects, pushing aside the boundaries of countries and nations, conferences

    The Gram-positive, spore-forming pathogen Clostridium difficile is the leading definable cause of healthcare-associated diarrhea worldwide. C. difficile infections are difficult to treat because of their frequent recurrence, which can cause life-threatening complications such as pseudomembranous colitis. The spores of C. difficile are responsible for these high rates of recurrence, since they are the major transmissive form of the organism and resistant to antibiotics and many disinfectants. Despite the importance of spores to the pathogenesis of C. difficile, little is known about their composition or formation. Based on studies in Bacillus subtilis and other Clostridium spp., the sigma factors σ(F), σ(E), σ(G), and σ(K) are predicted to control the transcription of genes required for sporulation, although their specific functions vary depending on the organism. In order to determine the roles of σ(F), σ(E), σ(G), and σ(K) in regulating C. difficile sporulation, we generated loss-of-function mutations in genes encoding these sporulation sigma factors and performed RNA-Sequencing to identify specific sigma factor-dependent genes. This analysis identified 224 genes whose expression was collectively activated by sporulation sigma factors: 183 were σ(F)-dependent, 169 were σ(E)-dependent, 34 were σ(G)-dependent, and 31 were σ(K)-dependent. In contrast with B. subtilis, C. difficile σ(E) was dispensable for σ(G) activation, σ(G) was dispensable for σ(K) activation, and σ(F) was required for post-translationally activating σ(G). Collectively, these results provide the first genome-wide transcriptional analysis of genes induced by specific sporulation sigma factors in the Clostridia and highlight that diverse mechanisms regulate sporulation sigma factor activity in the Firmicutes.

    OBJECTIVES The attributable cost of Clostridium difficile infection (CDI) in children is unknown. We sought to determine a national estimate of attributable cost and length of stay (LOS) of CDI occurring during hospitalization in children. DESIGN AND METHODS We analyzed discharge records of patients between 2 and 18 years of age from the Agency for Healthcare Research and Quality (AHRQ) Kids' Inpatient Database. We created a logistic regression model to predict CDI during hospitalization based on demographic and clinical characteristics. Predicted probabilities from the logistic regression model were then used as propensity scores to match 1:2 CDI to non-CDI cases. Charges were converted to costs and compared between patients with CDI and propensity-score-matched controls. In a sensitivity analysis, we adjusted for LOS as a confounder by including it in both the propensity score and a generalized linear model predicting cost. RESULTS We identified 8,527 pediatric hospitalizations (0.53%) with a diagnosis of CDI and 1,597,513 discharges without CDI. In our matched cohorts, the attributable cost of CDI occurring during a hospitalization ranged from $1,917 to $8,317, depending on whether model was adjusted for LOS. When not adjusting for LOS, CDI-associated hospitalizations cost 1.6 times more than non-CDI associated hospitalizations. Attributable LOS of CDI was approximately 4 days. CONCLUSIONS Clostridium difficile infection in hospitalized children is associated with an economic burden similar to adult estimates. This finding supports a continued focus on preventing CDI in children as a priority. Pediatric CDI cost analyses should account for LOS as an important confounder of cost.

    Background. Limited data are available on direct medical costs and lost productivity due to Clostridium difficile infection (CDI) in Canada. Methods. We developed an economic model to estimate the costs of managing hospitalized and community-dwelling patients with CDI in Canada. The number of episodes was projected based on publicly available national rates of hospital-associated CDI and the estimate that 64% of all CDI is hospital-associated. Clostridium difficile infection recurrences were classified as relapses or reinfections. Resource utilization data came from published literature, clinician interviews, and Canadian CDI surveillance programs, and this included the following: hospital length of stay, contact with healthcare providers, pharmacotherapy, laboratory testing, and in-hospital procedures. Lost productivity was considered for those under 65 years of age, and the economic impact was quantified using publicly available labor statistics. Unit costs were obtained from published sources and presented in 2012 Canadian dollars. Results. There were an estimated 37 900 CDI episodes in Canada in 2012; 7980 (21%) of these were relapses, out of a total of 10 900 (27%) episodes of recurrence. The total cost to society of CDI was estimated at $281 million; 92% ($260 million) was in-hospital costs, 4% ($12 million) was direct medical costs in the community, and 4% ($10 million) was due to lost productivity. Management of CDI relapses alone accounted for $65.1 million (23%). Conclusions. The largest proportion of costs due to CDI in Canada arise from extra days of hospitalization. Interventions reducing the severity of infection and/or relapses leading to rehospitalizations are likely to have the largest absolute effect on direct medical costs. PMID:26191534

    Full Text Available Tomefa E Asempa, David P Nicolau Center for Anti-Infective Research and Development, Hartford Hospital, Hartford, CT, USA Abstract: The burden of Clostridium difficile infection (CDI is profound and growing. CDI now represents a common cause of health care–associated diarrhea, and is associated with significant morbidity, mortality, and health care costs. CDI disproportionally affects the elderly, possibly explained by the following risk factors: age-related impairment of the immune system, increasing antibiotic utilization, and frequent health care exposure. In the USA, recent epidemiological studies estimate that two out of every three health care–associated CDIs occur in patients 65 years or older. Additionally, the elderly are at higher risk for recurrent CDI. Existing therapeutic options include metronidazole, oral vancomycin, and fidaxomicin. Choice of agent depends on disease severity, history of recurrence, and, increasingly, the drug cost. Bezlotoxumab, a recently approved monoclonal antibody targeting C. difficile toxin B, offers an exciting advancement into immunologic therapies. Similarly, fecal microbiota transplantation is gaining popularity as an effective option mainly for recurrent CDI. The challenge of decreasing CDI burden in the elderly involves adopting preventative strategies, optimizing initial treatment, and decreasing the risk of recurrence. Expanded strategies are certainly needed to improve outcomes in this high-risk population. This review considers available data from prospective and retrospective studies as well as case reports to illustrate the merits and gaps in care related to the management of CDI in the elderly.

    Clostridium difficile infection (CDI) is a bacterial infection of the digestive tract. Acute infections are accompanied by increased risk for venous thromboembolism (VTE). To date, there have been no studies of the rheological properties of blood during the course of digestive tract infections. The aim of our study was to examine the effects of CDI on red blood cell (RBC) rheology, specifically RBC deformability, RBC aggregation, and plasma viscosity. In addition, the activity of glucose 6 phosphate dehydrogenase (G6PD) and acetylcholinesterase (AChE) in RBC was studied. Our study group included 20 patients with CDI, 20 healthy persons comprised the control group. We examined the effects of CDI on the rheology of RBCs, their deformability and aggregation, using a Laser-assisted Optical Rotational Cell Analyzer (LORCA). Plasma viscosity was determined using a capillary tube plasma viscosymeter. Moreover, we estimated the activity of AChE and G6PD in RBC using spectrophotometric method. A statistically significant increase was found in the aggregation index, viscosity and activity of G6PD whereas the amount of time to reach half of maximum aggregation (t½) and the amplitude of aggregation (AMP) both showed statistically significantly decreases among patients with CDI compared to the control group. We also observed that the Elongation Index (EI) was decreased when shear stress values were low, between 0.3 Pa and 0.58 Pa, whereas EI was increased for shear stress in the range of 1.13-59.97 Pa. These observations were statistically significant. We report for the first time that acute infection of the gastrointestinal tract with Clostridium difficile is associated with abnormalities in rheological properties of blood, increased serum viscosity as well as increased aggregation of RBCs, which correlated with severity of inflammation. These abnormalities may be an additional mechanism causing increased incidence of VTE in CDI.

    Full Text Available The author examines cinema posters as a source of visual information. Based on the materials of Ukrainian cinema posters collection of V. Vernadsky National Library of Ukraine, the article analyzes posters, the compositions of which contain portrait pictures of Ukrainian and world cinema actors. It characterizes approaches which were used by the artists during their work of posters creaton in order to present the cinema activity of the actors through the creation of cinema images in graphics or collage technique. The author traces main stylistic peculiarities of the posters with portrait pictures and creative style of certain poster artists. It is worth acknowledging that nowadays unique posters to some films of 1920-1930s which have not been preserved up to the present are of special value as important artistic documents in the history of cinema. Despite the fact that the period of the first third of the twentieth century was an age of silent black-and-white films in the history of cinema, all the posters that accompanied the films release were colored, and together they became a bright and unique page in the history of Ukrainian graphic art and cinema advertising

  5. An Enhancement of Campaign Posters for Human Error Prevention in NPPs

    Accidents in high reliability systems such as nuclear power plants (NPPs) give rise to not only a loss of property and life, but also social problems. One of the most frequently used techniques to grasp the current situation for hazard factors in the NPPs is an event investigation analysis based on the INPO's Human Performance Enhancement System (HPES), and the Korean Human Performance Enhancement System (K-HPES) in Korea, respectively. There are many methods and approaches for an HE assessment that is valuable for investigating the causes of undesirable events and counter-plans to prevent their recurrence in the NPPs. They differ from each other according to the objectives of the analysis; the explanation of the event, the investigation of the causes, the allocation of the responsibility, and the establishment of the counter-plan. Event databases include their own events and information from various sources such as the IAEA, regulatory bodies, and also from the INPO and WANO. As many as 111 reactor trips have occurred in the past 5 years ('01∼'05), and 26 cases of them have occurred due to HE. The trend of human error rate didn't decrease in 2004, so the KHNP started to make efforts to decrease HEs. The KHNP created as many as 40 posters for human performance improvement in 2006. The INPO has been using a traditional form of poster; additionally, the Central Research Institute of Electric Power Industry (CRIEPI) developed a type of caution report. The caution report is comprised of a poster name, a serial number, a figure, work situations, the point at issue, and a countermeasure. The preceding posters which KHNP developed in 2006 give a message about specific information related to HE events. However, it is not enough to arouse interest in the effectiveness of the posters because most people are favorably disposed toward a simple poster with many illustrations. Therefore, we stressed the need for worker's receptiveness rather than notification of information

    Deuterium nuclear magnetic resonance was used to investigate the structure of different lipid fractions isolated from the anaerobic bacteria Clostridium butyricum and Clostridium beijerinckii. The fractions isolated from C. butyricum were (1) phosphatidylethanolamine/plasmenylethanolamine and (2) the glycerol acetal of plasmenylethanolamine, and from C. beijerinckii similar fractions containing principally (1) phosphatidyl-N-monomethylethanolamine, along with its plasmalogen, and (2) the glycerol acetal of this plasmalogen were isolated. The third fraction from both species consisted largely of the acidic lipids phosphatidylglycerol and cardiolipin along with plasmalogen forms of these lipids. Palmitic acid with deuterium labels at C-2, C-3, or C-4 or oleic acid with deuterium labels at C-2 and C-9,10 was added to the growth medium and incorporated to various extents in the lipid fractions. Biochemical analysis showed that palmitic acid and oleic acid were preferentially bound to the sn-2 and sn-1 positions, respectively, of the glycerol backbone when both fatty acids were added to the medium. From the 2 H NMR spectra, the hydrocarbon chain ordering near the lipid-water interface could be determined and appeared to be similar for all three lipid fractions. The deuterium quadrupole splitting and order parameter were low at the C-2 segment and increased by almost a factor of 2 at positions C-3 and C-4 for cells fed with deuteriated palmitic acid along with unlabeled oleic acid. These results agree with previous findings on pure diacyl lipids in which the sn-2 chain was found to adopt a bent conformation at the carbon segment C-2. However, two unusual quadrupole splittings could be detected for the plasmalogens. By comparison with other model systems it could be concluded that the double bond is aligned essentially parallel with the long axis of the hydrocarbon chains

    The main purpose of the present research is to study the reaction of cells of the hematopoietic system and carcinogenesis in the lungs of linear mice which were in the zone of the Chernobyl disaster for 1 month and their posterity (F1). It is established that the increase in frequency of micronucleated polychromatic erythrocytes in bone marrow for posterity F1 from mouse-parents being in the zone of the Chernobyl disaster had no statistical significance in comparison with the control groups. It is shown that the raising sensitivity of the posterity of linear mice, which were in the zone of the Chernobyl disaster, to the carcinogenic effect of urethane had more significance in comparison with the sensitivity of their parents. The estimate of the tumor process has shown that a spontaneous frequency of adenomas in the lungs for posterity F1 statistically increased more than 5 times in comparison with the similar parameter for the posterity of intact mice.

    Full Text Available Background: In most areas of medical research, the label of ‘quality’ is associated with well-accepted standards. Whilst its interpretation in the field of medical education is contentious, there is agreement on the key elements required when reporting novel teaching strategies. We set out to assess if these features had been fulfilled by poster presentations at a major international medical education conference. Methods: Such posters were analysed in four key areas: reporting of theoretical underpinning, explanation of instructional design methods, descriptions of the resources needed for introduction, and the offering of materials to support dissemination. Results: Three hundred and twelve posters were reviewed with 170 suitable for analysis. Forty-one percent described their methods of instruction or innovation design. Thirty-three percent gave details of equipment, and 29% of studies described resources that may be required for delivering such an intervention. Further resources to support dissemination of their innovation were offered by 36%. Twenty-three percent described the theoretical underpinning or conceptual frameworks upon which their work was based. Conclusions: These findings suggest that posters presenting educational innovation are currently limited in what they offer to educators. Presenters should seek to enhance their reporting of these crucial aspects by employing existing published guidance, and organising committees may wish to consider explicitly requesting such information at the time of initial submission.

    Full Text Available The action reserach aims at improving the students’ writing skill especially to write advertsements and posters. Both are the short functional texts to be learned at the second semester. According to the data on pre cycle, the students of second semester got difficulties to write advertisements and posters. A treatment was necessary to help the students overcome their problem. To consider the related literature, the writer decided to implement ESA sequence (Harmer 2001 in the class. The elements of teaching in ESA Sequence are Engage (to arouse the students’ interests, Study (learn the language focus, and Activate (use the language freely and communicatively. The data were taken from the test of the linguistic competence mastery, the students writing, and the questionnaire. The students’ linguistic competence got increased as shown by the score (58 in pre-cycle, 66 in cycle 1, and 70 in cycle 2. The students’ ability to write the short functional texts also get improved as indicated by the average score on writing tasks (53 in pre-cycle, 63 in cycle 1, 72 in cycle 2. The interest also gets better as shown by the score of the questionnaire (22,3 in pre-cycle, 33,5 in cycle 1, and 37 in cycle 2. It means ESA Sequence can improve the studets’ ability to write advertisements and posters.Key words : advertisement, ESA (Engange Study Activate, poster

    We have redesigned a tried-and-true laboratory exercise into an inquiry-based team activity exploring microbial growth control, and implemented this activity as the basis for preparing a scientific poster in a large, multi-section laboratory course. Spanning most of the semester, this project culminates in a poster presentation of data generated from a student-designed experiment. Students use and apply the scientific method and improve written and verbal communication skills. The guided inquiry format of this exercise provides the opportunity for student collaboration through cooperative learning. For each learning objective, a percentage score was tabulated (learning objective score = points awarded/total possible points). A score of 80% was our benchmark for achieving each objective. At least 76% of the student groups participating in this project over two semesters achieved each learning goal. Student perceptions of the project were evaluated using a survey. Nearly 90% of participating students felt they had learned a great deal in the areas of formulating a hypothesis, experimental design, and collecting and analyzing data; 72% of students felt this project had improved their scientific writing skills. In a separate survey, 84% of students who responded felt that peer review was valuable in improving their final poster submission. We designed this inquiry-based poster project to improve student scientific communication skills. This exercise is appropriate for any microbiology laboratory course whose learning outcomes include the development of scientific inquiry and literacy. PMID:29904518
