Dr. Natascha Meunier, Beef HealthCheck Programme Manager, is on this week's Beef Edge podcast to discuss how to control liver fluke effectively and understand it better. Liver fluke is estimated to cost at least €90m to the Irish industry through reduced production and Natascha highlights how the incidence of liver fluke on this year's Beef HealthCheck reports have doubled from 1% to 2%: https://animalhealthireland.ie/programmes/beef-healthcheck/beef-healthcheck-online/ Each year, the Department of Agriculture, Food and the Marine (DAFM) in collaboration with Met Éireann, UCD, Teagasc and Animal Health Ireland advises farmers of the predicted risk of disease caused by liver fluke (Fasciola hepatica) infection in livestock for the following winter.  This year's forecast, based on meteorological data gathered between May and October 2024 by Met Éireann, predicts infection being most prevalent in the west and northern half of the country, with a somewhat lower disease prevalence in the southeast of the country.  Further details here:https://www.gov.ie/ga/preasraitis/48ce4-liver-fluke-forecast-november-2024/ Natascha explains that while the Beef Health Check report is retrospective, it's important to review when cattle are finished if the health plan is working. Natascha also discusses the importance of faecal sampling and the different treatment options.  It's important for farmers to be vigilant especially if liver fluke has never been an issue on their farm in the past and she explains how rumen fluke can be identified and when to take action. With the majority of stock housed in the past few weeks, Natascha advises in relation to respiratory issues, anthelmintics and importance of housing ventilation and air quality. For further information on AHI Liver Fluke - The Facts:https://www.animalhealthireland.ie/ckfinder/userfiles/files/Animal%20Health%20Liver%20Fluke%206pp-web(1).pdf  For more episodes from the Beef Edge podcast, visit the show page at:https://www.teagasc.ie/thebeefedge Produced on behalf of Teagasc by LastCastMedia.com

Back in series 1 we discussed Liver Fluke but today we're going to dive into the subject in more detail and talk about how to approach a season where the risk of liver fluke is predicted to be high. In the past many farmers would have heard the risk is high and simply reached for the drench gun - today we want to explore why that is no longer an effective option and talk about the available alternatives. Host Ben Eagle is joined by Lesley Stubbings, Independent Consultant working with SCOPS. We are also joined by John Graham-Brown from the University of Liverpool, Joe Angell a vet from Wern Vets in North Wales and farmer Alex Crossley. Useful Links:https://www.nadis.org.uk/parasite-forecast.aspxhttps://www.scops.org.uk/internal-parasites/liver-fluke/Testing for liver fluke: A joint SCOPS and COWS webinar to introduce the new lateral flow test | Webinars | National Sheep AssociationLiver Fluke Rapid Antibody Test | Norbrook LaboratoriesLack of efficacy of triclabendazole against Fasciola hepatica is present on sheep farms in three regions of England, and Wales - Kamaludeen - 2019 - Veterinary Record - Wiley Online Library

In der vorliegenden Arbeit wurden insgesamt 497 Patienten mit mikroskopisch gesicherten Helminthiasen hinsichtlich epidemiologischer und klinischer Daten sowie auf indirekte Laborparameter (Eosinophilie und Gesamt-IgE-Erhöhung) und die Resultate immundiagnostischer Verfahren untersucht. Hierbei wurden die Ergebnisse von 329 Reiserückkehrern und 168 Migranten mit jeweils 8 Diagnosen (Ankylostomiasis, Askariasis, Fasziolose, Filariose, Schistosomiasis, Trichinose, Trichuriasis, Mischinfektionen) miteinander verglichen. Für die Evaluation der immundiagnostischen Verfahren wurden vorhandene Seren mit 9 Antigenen (Schistosoma mansoni, Onchocerca volvulus, Dirofilaria imitis, Trichinella spiralis, Fasciola hepatica, Toxocara canis, Strongyloides ratti, Ascaris lumbricoides, Ascaris suum) getestet. Vorbestehende Ergebnisse aus der Routinediagnostik wurden mit einbezogen. Als Kontrollen dienten die Seren von 80 gesunden Personen ohne Hinweise auf eine Wurmerkrankung in der Vorgeschichte und ohne einen vorherigen Aufenthalt in den Tropen oder Subtropen. Die epidemiologischen Daten zeigen eine eindeutige Zuordnung von Schistosomiasis und Filariosen auf den afrikanischen Kontinent, während die Geohelminthiasen (Erkrankungen durch Helminthen, deren präadulte Stadien sich im Erdboden entwickeln und die eine reise- bzw. migationsmedizinisch wichtige Bedeutung haben) von den Reiserückkehrern vorwiegend in Asien, vorzugsweise in Südostasien, akquiriert wurden. Die Migranten stammten hauptanteilig aus Afrika, es waren dennoch alle wesentlichen tropischen und subtropischen Gebiete vertreten. Die Auswertung der klinischen Symptomatik zeigte ein klares Erscheinungsbild der Filariosen mit Hauterscheinungen und Juckreiz sowie die überdurchschnittlich häufige Angabe von Harnwegsbeschwerden bei Infektionen mit Schistosoma haematobium. Bei allen Geohelminthosen und Infektionen mit Schistosoma mansoni herrschte bei den Reiserückkehrern eine gastrointestinale Symptomatik vor, während die Migranten insgesamt mehr unspezifische Beschwerden aufwiesen. Circa ein Drittel der Patienten war asymptomatisch. Die Sensitivität der Eosinophilie als indirekter Parameter lag in dieser Arbeit für Wurmerkrankungen im Allgemeinen bei 45%, variierte aber von Diagnose zu Diagnose erheblich, wobei kein signifikanter Unterschied zwischen Reiserückkehrern und Migranten zu finden war. Eine Hypereosinophilie fand sich überdurchschnittlich häufig bei Migranten mit Filariose und bei Reiserückkehrern mit Strongyloidiasis; die Patienten mit Askariasis und Trichuriasis zeigten dagegen kaum Abweichungen von der Kontrollgruppe. Eine Gesamt-IgE-Erhöhung fand sich insgesamt bei 43% der Patienten, wobei es einen signifikanten Unterschied zwischen Reiserückkehrern (25%) und Migranten (75%) gab. Besonders hohe IgE-Serumspiegel konnten bei Migranten mit Schistosomiasis, Strongyloidiasis und Ankylostomiasis gefunden werden. Davon abweichend waren allerdings die Resultate von Reiserückkehrern mit Mischinfektionen. Bei diesen Patienten konnte eine unerwartet häufige Gesamt-IgE-Erhöhung verzeichnet werden (75%). Die serologischen Untersuchungen zeigten zumeist eine gute Sensitivität, aber erhebliche Kreuzreaktionen mit verwandten und nicht verwandten Wurmarten, sodass eine Differenzierung nur für die Schistosomiasis und die Filariosen valide gewährleistet ist. Der im Rahmen dieser Arbeit entwickelte Ascaris suum-ELISA, ergab eine Sensitivität von 60% und eine Spezifität von 90% und hat in der Routinediagnostik eine gewisse Berechtigung, da der Ascaris lumbricoides-ELISA inakzeptable Ergebnisse erbrachte. Zusammengefasst stellt die Eosinophilie einen wichtigen hinweisenden Parameter auf eine Wurminfektion dar, ist aber keine ausreichende Screeningmethode bei Rückkehr aus Endemiegebieten. Die serologischen Untersuchungen ergaben eine sinnvolle diagnostische Ergänzung bei der Schistosomiasis und den Filariosen. Eine Differenzierung der Geohelminthosen ist weiterhin nur durch direkte Nachweismethoden, wie z. B. dem Ei- bzw. Larvennachweis im Stuhl oder in einem Körpergewebe, verlässlich möglich.

Investigations on the seroprevalence of Fasciola hepatica in Bavarian dairy cattle 5278 bulk tank milk samples were randomly collected from 66 Bavarian districts over a period from February 2003 to March 2005. The samples were tested for antibodies against F. hepatica by the use of an ELISA (astablished by Pourquier/Montpellier/France). The period of examination was adapted to the lifecycle of the parasite and the intermediate host. The used »f2« antigen detecting ELISA presents a suitable screening method for the diagnosis on herd level and large scale surveillance programs and is to perform automatically from easily obtained bulk milk. The distribution and prevalence of fasciolosis showed huge differences in the 66 examined rural districts. An overall prevalence of 32.2% could be determined for Bavaria. Prevalences of 4.39% up to 47.23% were found in the 7 administrative districts. It is highly significant that more frequently the liver fluke was detected in Oberbayern (47.23%). A reason for this finding could be the traditional housing systems in this area as well as the geographical position. In Oberfranken (33.18%), Schwaben (33.71%) and Niederbayern (35.33%) similar seroprevalences were detected without significant differences to Bavaria as a whole. In Mittelfranken (24.29%), Unterfranken (4.39%) and Oberpfalz (18.04%) significant lower prevalences were found than in complete Bavaria. The overall prevalence in the alpine uplands of Bavaria amounts to 64.48%. In the alpine upland rural districts Lindau am Bodensee, Oberallgäu, Ostallgäu, Bad Tölz, Miesbach and Bad Reichenhall seroprevalences of 85% - 97.5% were determined. A remarkable high prevalence of 95% was found in the rural district Wunsiedel im Fichtelgebirge (Oberfranken). Because of the river systems in the Fichtelgebirge there exist a lot of wetlands and flood plains (Hermann 2005). Fürth (43.75%), Weißenburg-Gunzenhausen (43.75%) and Roth (46.75) showed the highest prevalences in Mittelfranken. In the three districts significant differences to the overall prevalence of Bavaria were detected.

During the year 2002 319 cattle from 31 farms (6 districts) of southern Bavaria were investigated for the presence of ticks during the grazing period and 287 serum samples were tested for the presence of antibodies against Borrelia burgdorferi and Babesia divergens. Ticks were detected in all 31 farms and the mean prevalence was 69 %. 3218 out of 3453 collected ticks were Ixodes ricinus. 139 nymphs, 19 larvae and 77 damaged adult specimens could only be determined to the Genus level (Ixodes). The seasonal pattern revealed the highest frequencies of ticks in May/June and September. The intensity of the infestation of the 221 positive animals was generally low. 76,5 % of parasitized individuals had 1-6 ticks/cattle and day of investigation. By contrast, individuals on pastures with appropriate tick-habitats showed up to 250 ticks/cattle and day of investigation. The percentage of infested animals in each herd varied within the period between 0 100 %. The investigation of 287 serum samples for the presence of antibodies against Borrelia burgdorferi by immunfluorescence techniques (IFAT), revealed antibody-titers ≥ 1:64 for 45,6 % of the animals. 27 of 31 farms showed prevalences of Borrelia burgdorferi ranging from 20 to 100 %. There were no significant differences of positive cattle between the various areas. However, a significant correlation could be detected between the number of ticks per cattle and the antibody concentration of anti-Borrelia IgG. By contrast, there was no significant correlation between the age of the animals and the serum antibody-titers. For comparative reasons, 64 IFAT-positive serum samples were tested by Westernblot techniques for the presence of antibodies cross-reacting with Borrelia garinii antigens. These analyses revealed that 69 % of the samples reacted positively, 28 % were unclear and 3 % were negative. The investigation of the 287 cattle sera for Babesia divergens by means of IFAT revealed one positive animal with an antibody-titer of 1:16. Finally, in an additional enzyme linked immunosorbent assay (ELISA) 105 serum samples from 18 farms and 13 pooled sera including 45 cattle from the other 13 farms were tested for the presence of antibodies against Fasciola hepatica. In 96,8 % of the farms antibodies against Fasciola hepatica could be detected.
