Traditional methods for animal identification have a number of drawbacks. We evaluated a new system for individual identification using microchip implants in rabbits, guineapigs, woodchucks ( Marmota monax) and amphibians ( Xenopus laevis, Pleurodeles waltlii). Implantation procedure and long-term observations are described. Microchip implants proved to be a practicable and reliable system for animal identification without obvious adverse effects. The applicability of electronic animal identification in comparison with common methods and with regard to animal welfare and legal aspects is discussed.
SummaryAir filter sets lclasses EU6 and EU9, or EU6 and S) were tested for their efficiency in protecting laboratory animals against potential airborne infections. Flexible-film isolators were used as a smaller scale model. In the first experiment, lasting 7 months, it was tested whether minute virus of mice (MVM) was able to penetrate the airfilters between one isolator containing experimentally infected mice and another with MVM negative mice. In the second experiment we tested whether microorganisms in the incoming air were able to penetrate air filter sets. To assess this gnotobiotic mice in an isolator were monitored for 9 months for changes of their microbial flora. In both experiments a combination of EU6 and EU9 air filters proved to be sufficient to maintain the microbiological status of the animals. The same combination of medium efficiency filters (EU6 and EU9) is used on the air supply to 4 SPF-barrier units in which infections with MVM occurred repeatedly soon after the initial stocking. After a thorough disinfection no reinfection has been detected to date. This demonstrates that the relatively low efficiency of the air filters was not the cause of the repeated infection. The procedure for disinfection is described.
In den letzten Jahren sind verschiedene Empfehlungen herausgegeben worden, die eine Hilfestellung zur fachgerechten Bek?mpfung von Parasiten bei Hund und Katze leisten (z.?B. www.esccap.org). Sie bieten eine fundierte Basis, k?nnen aber naturgem?? nicht jederzeit die neuesten Erkenntnisse aus der Forschung enthalten. Aktuelle wissenschaftliche Ergebnisse zu vektor?bertragenen Krankheiten und Parasitosen sind in diesem Beitrag praxisnah zusammengefasst. Vorgestellt wurden sie k?rzlich bei einem Round-Table-Gespr?ch, bei dem es ein besonderes Anliegen war, die Themen interdisziplin?r aus verschiedenen Perspektiven zu beleuchten.
Parasitosen und durch Parasiten ?bertragene Krankheiten bei Hund und Katze werden vielfach thematisiert. Ihrer klinischen Bedeutung entsprechend wurden und werden Empfehlungen zu ihrer Bek?mpfung entwickelt (siehe z.?B. www.esccap.de). Neue Projekte und aktuelle Ergebnisse wurden k?rzlich von Experten aus Klinik und Parasitologie bei einem Round-Table-Gespr?ch vorgestellt und diskutiert.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
