D'un commun accord avec les chirurgiens et avec le soutien des directions médicale et inFirmière, nous avons mis sur pied "les 12 actions au BOP", dans le but de réduire ces inFections, avec le leitmotiv "où il n'y a pas de standard, il ne peut pas y avoir d'amélioration". Méthode Chaque mois: • Un nouveau thème est abordé avec l'appui d'ambassadeurs proFessionnels du terrain, dans le but de gagner en discipline et en standardisation des pratiques. • Une procédure est établie. • Un slogan court et percutant est mis en évidence. • Si nécessaire, du matériel pédagogique est élaboré (ex: une vidéo de la désinFection chirurgicale des mains tournait en boucle près des lavabos). Les thèmes abordés jusqu'ici sont: • DésinFection chirurgicale des mains: et si vous... preniez 1 minute 30 pour réaliser une désinFection chirurgicale des mains dans les règles de l'art? • Antibioprophylaxie: et si vous... optimisiez l'antibioprophylaxie? • Protections Faciale et oculaire: et si... les têtes intelligentes (se) protégeaient? • Limitation des dérangements: s'il vous plait, j'ai besoin de calme pour travailler! • Le sondage vésical: et si le sondage vésical était... plus rare, plus court, plus sûr? • Normothermie: et si vous... mainteniez le patient au chaud: objectiF commun 36.5°! • Préparation cutanée du patient: le patient / la patiente a Fait sa part, à vous de Faire la vôtre! Résultats Le succès des diFFérentes actions est variable. La technique de désinFection chirurgicale des mains a été largement adoptée et des progrès ont été constatés dans l'administration de l'antibioprophylaxie. Par contre, les lunettes de protection sont toujours peu portées et les bijoux sont réapparus presqu'aussi vite qu'ils avaient disparu. Les chirurgiens apprécient de pouvoir pointer le poster pour demander du silence, mais les va-et-vient n'ont pas diminué. Le choix de l'antiseptique avant pose d'une sonde vésicale n'est pas toujours le bon. Conclusion Le projet n'est pas terminé, mais son impact est mitigé. Certains nous reprochent que les actions visant à la discipline et la standardication ne sont pas evidence based. Et les mêmes nous disent "oui, mais..." lorsque l'évidence est présente! L'impact sur les taux d'inFection sera difFicile à démontrer. Cependant, les proFessionnels renouent peu à peu le dialogue entre corporations, pour un but commun. HH-2 "Neues Hygienekonzept für das Universitätsspital Zürich" – Eindeutig, benutzerfreundlich, zugänglich A WolFensberger; M Meier; L Clack; H Sax Universitätsspital Zürich Aims: SchriFtlich Festgelegte Weisungen (Standard Operating Procedures) bilden die Basis einer zuverlässigen Organisation. Die unvollständige Umsetzung dieser Regeln in der Praxis scheitert u.a. häuFig an einer geringen Zugänglichkeit und Benutzerfreundlichkeit. Durch ein grundlegendes Re-Design des Hygienekonzepts sollte die Umsetzung der Regeln erleichtert werden – mit dem Ziel, das inFektiöse Risiko Für Patienten, Besucher und Mitarbeitende im UniversitätsSpital Zürich zu reduzieren. Methods: Das Re-Design erFolgte mit einem Human Factors Engineering-Ansatz, d.h. einer Analyse der Arbeitsabläufe, einer interdisziplinären Erarbeitung der Regeln und einer iterativen Testung von Prototypen. Folgende Prinzipien wurden verFolgt: Hohe Zugänglichkeit der benötigten InFormation, Darstellung mit AbstuFung des Detailgrades (das einfache, aktionsrelevante zuerst), hohe Konsistenz und Eindeutigkeit durch durchgehende Terminologie und Symbolik, Erleichterung der Merkbarkeit durch Symmetrien und Symbole, maximale Usability und zuletzt Implementierung durch eine multidimensionale Strategie bottom-up und top-down. Results: Das neue Hygienekonzept des USZ besteht aus Folgenden Elementen. 1) Hygieneorder: wurde von mehr als 100 auF 35 meist zweiseitige, klar strukturierte Dokumente reduziert. 2) Intranetseite Spitalhygiene: grafisches Design, einheitlich strukturiert und schnell Lesbar. 3) Signage: Türschilder Für isolierte Patienten nach Prinzipien der InfograFik. 4) Pocket-Card: Drehscheibe mit Information zu Isolationsmassnahmen und InFektionsprävention. 5) Minuten-Videos: Lehrvideos zu Isolationsmassnahmen. 6) Spitalhygiene-Film «Willkommen an Bord – InFektionsprävention am USZ»: FünFminütiger Film mit «Edutainment»-Charakter zum Thema Standardmassnahmen. Conclusion: Das neue Hygienekonzept des USZ wurde im Juni 2016 im USZ implementiert und hat aufgrund des ansprechenden Designs, seiner Klarheit und EinFachheit und der teilweise verspielten und unterhaltenden Elemente viel Lob erhalten Shared First Authorship: Aline Wolfensberger and Marie-Theres Meier. HH-3 Erfolgreiche Umsetzung eines neuen Hygiene-Schulungskonzeptes I Schürmann; D Jegher; C Rohrer; E Sidler; E Rohrer; E MossdorF; S Ambauen; J Weber; C Orasch Hirslanden Klinik St. Anna Einleitung Spitalhygiene dient der Prävention nosokomialer InFektionen und ist wichtig Für die Patientensicherheit und Behandlungsqualität. Sie ist Aufgabe eines jeden Mitarbeiters (MA). Durch regelmässige Schulungen soll das notwendige Hygiene-Wissen vermittelt und auFgefrischt werden. Klassische Hygienefortbildungen wurden in unserer Klinik schlecht besucht. Ziel Umstrukturierung des Hygiene-Schulungskonzepts mit einem Angebot, welches das notwendige Wissen vermittelt, im Arbeitsalltag integriert ist und möglichst viele MA erreicht. Methode Nach der Analyse bisheriger Kommunikations-/SchulungsplattFormen wurde das neue Hygiene- Schulungskonzept entwickelt. Die wichtigsten Hygienethemen wurden definiert und jeweils ein Schulungsthema pro Monat in 15 minütige, patientenzentrierte und praxisbezogene und kurzweilige Fortbildungen mit verschiedenen PräsentationsFormen (Poster, Rollen- /Fragespiel etc.) gepackt. Die Fachexpertin Hygiene (FaH) schult auF jeder Abteilung das gleiche Thema, direkt auF Station/im Arbeitsbereich und während der Arbeitszeit. Für die Schulung der nicht-anwesenden MA sind die link nurses Hygiene (LNH) verantwortlich. Sie organisieren mit den von der FaH zur VerFügung gestellten Fortbildungs-Unterlagen die Nachschulungen. Es wurden 2 Punktprävalenzmessungen mit Fokus Venenkatheter sowie Händehygiene-Beobachtungen (vorher – nachher) durchgeFührt. Nach 9 Monaten wurde mit einem strukturierten Fragebogen das Feedback der Geschulten eingeholt. Resultate Der RücklauF der Fragebogen lag bei 75% (n=207). Die Fragen „Sind die Hygiene-Schulungen Für meine Arbeit wichtig“ wurden in 96.6% (n=200); „Kann das Gelernte in der täglichen Arbeit umgesetzt werden“ in 91%(n=188); „Wird mein Wissen auFgeFrischt/lerne ich dazu“ in 89% (n=185) und „Ist das neue Schulungskonzept besser“ in 93% (n=160) positiv beantwortet. 60.3 % (n=1123) der 1863 angebotenen Schulungen wurden besucht, 79.8% davon von der FaH und 19.9% von den LNH durchgeFührt. An messbaren Parametern wurden ein nach den Schulungen verbesserter Umgang mit Venenkathetern mit einer Abnahme der Venenkatheter-InFektionen und eine Verbesserung der Händehygiene festgestellt. Konklusion Das neue Hygiene-Schulungskonzept mit kurzen, praxisbezogenen Fortbildungen direkt am Arbeitsplatz ist bei den MA sehr gut angekommen und hat zu messbar verbesserten Hygiene-Parametern geführt. Wir werden es weiterFühren und die Nachschulungen optimieren, mit dem Ziel, möglichst alle MA den Schulungen zuzuFühren. HH-4 Hand Hygiene campaign to improve compliance in nursing homes L Qalla-Widmer; D Héquet; M Attinger; C Petignat CHUV Unité HPCI The Unit For InFection Control and Prevention oF Canton Vaud (Switzerland) gives a high priority to preventing healthcare associated infections. Several studies have demonstrated that hand hygiene can signiFicantly reduce the cross-transmission of pathogens. Unfortunately, health-care worker’s observance to guidelines remains limited. In 2012-2014, a First successFul hand hygiene campaign was conducted in nursing homes (NH) oF the Canton Vaud. In order to sustain achievements, a second campaign was planned in 2016. The purpose oF this campaign was to assess hand hygiene compliance amongst the NH stafF in 2016 and to determine the evolution over time, comparing the Findings to previous campaign. First, hand hygiene and gloves workshops were organized in NH. Then, direct observations were perFormed according to the WHO moments For hand hygiene. NH were

Królewicza 4, 71-550, Szczecin, Poland Abstract Most diseases induced by herpesviruses are host-specific; however, exceptions exist within the family Alloherpesviridae. Most members of the Alloherpesviridae are detected in at least two different species, with and without clinical signs of a disease. In the current study the Koi herpesvirus (KHV) was used as a model member of the Alloherpesviridae and rainbow trout as a model salmonid host, which were infected with KHV by immersion. KHV was detected using direct methods (qPCR and semi-nested PCR) and indirect (enzyme-linked immunosorbant assay; ELISA, serum neutralization test; SNT). The non-koi herpesvirus disease (KHVD)-susceptible salmonid fish were demonstrated to transfer KHV to naïve carp at two different temperatures including a temperature most suitable for the salmonid (15°C) and cyprinid (20°C).

C 2 Shichirigahama Senior High School, 2-3-1, Shichirigahama-higashi, Kamakura-shi, Kanagawa 248-0025 Japan E-mail• dp7a-tnkw@ j.asahi-net.or.jp Abstract - Five orb-weaving species of the families Tetragnathidae and Araneidae are newly recorded from Taiwan. These include tetragnatid species Leucauge argentina (Hasselt 1882), L. tessellata (Thorell 1887), Mesida gemmea Hasselt 1882 and araneid species Eriovixia excelsa (Simon 1889), E. sakiedaorum Tanikawa 1999. The tetragnathid genus Mesida is recorded from Taiwan for the first time. The morphology of these five orb-weaving species are described and illustrated, and the synonyms and distribution accounts are given in this paper. Key words - Eriovixia excelsa, Eriovixia sakiedaorum, Leucauge argentina, Leucauge tessel- lata, Mesida gemmea, Taiwan, new records Introduction Among around three hundred species of spiders recorded from Taiwan (Chen 1996), ecribellate orb-weavers (family Araneidae and Tetragnathidae) have received relatively greater attention. Although census methods such as pitfall trapping have been gradually adopted in the current investigation of Taiwanese spider fauna, in the past few decades most of the collections were performed by visual inspection. With this method, orb-weaving spiders are easier to be located and collected than other Araneae taxa, because orb web construction not only makes the spiders more conspicuous, but also restricts their movement (Robinson & Robinson 1974).

However, the diversity of the DNA and retro-transcribing viruses in these host groups was left uncharacterized. Given that RNA sequencing is capable of revealing viruses undergoing active transcription and replication, we collected previously generated datasets associated with lower vertebrate hosts, and searched them for DNA and retro-transcribing viruses. Our results revealed the complete genome, or “core gene sets”, of 18 vertebrate-associated DNA and retro-transcribing viruses in cartilaginous fishes, ray- finned fishes, and amphibians, many of which had high abundance levels, and some of which showed systemic infections in multiple organs, suggesting active transcription or acute infection within the host. Furthermore, these new findings recharacterized the evolutionary history in the families Hepadnaviridae, Papillomaviridae, and Alloherpesviridae, confirming long-term virus–host codivergence relationships for these virus groups.

    www.nature.com/scientificreports OPEN Bufonid herpesvirus 1 (BfHV1) associated dermatitis and mortality in free ranging common toads Received: 19 January 2018 Accepted: 17 September 2018 (Bufo bufo) in Switzerland Published: xx xx xxxx Francesco C. Origgi1, Benedikt R. Schmidt 2,3, Petra Lohmann4, Patricia Otten5, Roman K. Meier1, Simone R. R. Pisano1, Gaia Moore-Jones1, Marco Tecilla6, Ursula Sattler1, Thomas Wahli1, Veronique Gaschen7 & Michael H. Stofel7 Here we report the discovery and partial characterization of a novel herpesvirus tentatively named Bufonid herpesvirus 1 (BfHV1) from severe dermatitis in free ranging common toads (Bufo bufo) in Switzerland. The disease has been observed in toads every year since 2014, in spring, during the mating season, at diferent and distant locations. The virus is found in the skin and occasionally in the brain of infected toads. The genome of the virus is at least 158 Kb long and contains at least 152 open reading frames with a minimal length of 270 nt. The genome of BfHV1 contains all the signature genes that are present in alloherpesviruses. Phylogenetic analysis based on the amino acid sequence of the DNA polymerase and terminase proteins positions the novel virus among the members of the genus Batrachovirus, family Alloherpesviridae. This is the frst herpesvirus ever characterized in common toads. Amphibians are undergoing a major decline worldwide1,2. Te reasons for this unprecedented loss in biodiversity are only partially understood3. Among potential contributors, infectious diseases have recently raised attention as important players4,5. In addition to well-characterized amphibian pathogens including chytrids6–9 and rana- viruses5,10,11, it is likely that other pathogens or putative pathogens, whose role in amphibian disease ecology is basically unknown, though not irrelevant, are still to be discovered and better investigated12.
