Veröffentlichung Antibiotics and Antibiotic Resistances in the Environment(2018) Adler, Nicole; Balzer, Frederike; Blondzik, Katrin; Brauer, Frank; Chorus, Ingrid; Ebert, Ina; Fiedler, Traute; Förster, Christina; Heidemeier, Joachim; Grummt, Tamara; Hein, Arne; Helmecke, Manuela; Hilliges, Falk; Kirst, Ingo; Konradi, Sabine; Klasen, Jutta; Küster, Anette; Krause, Bernd; Pirntke, Ulrike; Roskosch, Andrea; Schönfeld, Jens; Selinka, Hans-Christoph; Straff, Wolfgang; Szewzyk, Regine; Westphal-Settele, Kathi; Deutschland. UmweltbundesamtEnvironmental aspects have so far only partially been addressed in the discussion of antimicrobial resistance. To bring this issue into focus, UBA compiled background information and data on the topic 'Antibiotics and antimicrobial resistance in the environment'. The results show that previously considered requirements for reduction, from the perspective of UBA, are insufficient to adequately protect health and the environment. UBA sees urgent need for improvement and proposes possible options for action.Veröffentlichung Experimental Design for Efficacy Testing of Baits Against Monomorium pharaonis (Hymenoptera: Formicidae)(2014) Krüger, Anne; Klasen, Jutta; Schmolz, ErikIn the European Union, baits against pharaoh ants (Monomorium pharaonis) have to be authorized asbiocidal products. The dossier to be submitted for authorization of the product has to include a proof of productefficacy. No consistent test standards have been established by the European Commission. A test method forefficacy testing of baits against Pharaoh ants was published by the Federal Environment Agency Germany in1998 and is in use for efficacy tests according to the German Infectious Diseases Protection Act. The test systemis a test arena of interconnected test boxes (each 25 cm x 25 cm). In our study, this test system was comparedwith a dish (diameter 23 cm) as test arena. Test duration was 50 days for both arena types (boxes and dish) forchoice and 20 days for no-choice tests. The results for choice tests revealed that in the box system more colonieswere eradicated (boxes: 75%, dishes: 0%) within 50 d, and more queens died (average number of survivingqueens was 0.5 in boxes and 29.7 in dishes).

UmweltbundesamtDie Rolle der Umwelt wird bei der Entwicklung von Antibiotikaresistenzen bisher nur ansatzweise diskutiert. Um dieses Thema in den Focus zu bringen, veröffentlicht das UBA eine Zusammenstellung von Hintergründen und Daten zu dem Thema "Antibiotika und Antibiotikaresistenzen in der Umwelt". Die Ergebnisse zeigen, dass die bisher berücksichtigten Anforderungen zur Minderung aus Sicht des UBA nicht reichen, um Umwelt und Gesundheit ausreichend zu schützen. Das UBA sieht dringenden Nachbesserungsbedarf und schlägt mögliche Handlungsoptionen vor.
