Última Untersuchungen zur Wirksamkeit von Anthelminthika bei erstsömmrigen Rindern in Europa Organic Eprints Demeler, J.; Kleinschmidt, N.; Koopmann, R.; Samson-Himmelstjerna, von, G.. Resistance to anthelmintics is a threat to several animal industries world wide. Nevertheless, the use of effective anthelmintics to control nematode infections in cattle still remains irreplaceable. Anthelmintic resistance in cattle has been reported in New Zealand, North and South America and England but so far not in Europe. To be able to determine the extent of anthelmintic resistance in nematodes of farm animals and to monitor the success of any resistance management requires reliable tests for the detection of anthelmintic resistance. One of the objectives of PARASOL, a European Framework 6 funded project, is to produce standard operating procedures for the running of a faecal egg count reduction test (FECRT). Standardized procedures for the... Tipo: Conference paper, poster, etc. Palavras-chave: Health and welfare. Ano: 2009 URL: http://orgprints.org/14455/1/Demeler_14455.pdf Incidence of anthelmintic resistance in cattle farms in Northern Germany – first results Organic Eprints Kleinschmidt, N.; von Samson-Himmelstjerna, G.; Demeler, J.; Koopmann, R.. Anthelmintic resistance (AR) is an increasing problem worldwide especially for small ruminants and it is also rising in cattle. To maintain the efficacy of anthelmintics is an important objective. The current project aims at the investigation of the current efficacy of macrocyclic lactone anthelmintics for strongylid nematodes in first season grazing (FSG) calves in Northern Germany. On 8 participating farms in Northern Germany faecal egg count reduction tests (FECRT) with ivermectin (IVM) were performed. On 3 farms the efficacy of IVM was found to be ≤90% and on only 4 farms it was > 95% at 14 days post treatment (d.p.t.). Only 2 farms showed a reduction ≥ 95% at 21 d.p.t.. This survey reveals a rising problem of AR. The problem of drug resistance... Tipo: Conference paper, poster, etc. Palavras-chave: Health and welfare.
