“…The results of this study are similar to the prevalence (78%) among Irish dairy farms (Selemetas et al, 2015c), but higher than the prevalence of 65% found in culled cows during autumn and summer (Murphy et al, 2006), which could be the result of different climatic and environmental conditions or different sampling time period, as the peak of the annual cycle of fasciolosis is expected in late autumn due to pasture contamination at the end of summer (Salimi-Bejestani et al, 2005a). In general, the high prevalence observed in Irish dairy farms can be associated with the combination of temperate climate and high level of grass-based diet during grazing period that can raise the exposure to parasites (O'Farrell et al, 1986).…”

“…In the present study, the overall F. hepatica seroprevalence was 28.7% (454/1,584), which was lower than that reported in yaks in Xinghai tested by autopsy method [9,10], cattle in Switzerland [14], Poland [14], Australia [15], Ireland [16], and Vietnam [17] examined by ELISA, but higher than that of cattle in Spain [5] and Denmark [18], cow in Germany [19] tested by ELISA. It has been demonstrated that F. hepatica infection mainly occurs in cattle [20] and goats [20], otherwise, F. gigantica usually infect water buffaloes.…”

The aim of this study was to determine the seroprevalence and risk factors of fascioliasis in yaks, Bos grunniens, from 3 counties of Gansu Province in China. A total of 1,584 serum samples, including 974 samples from white yaks from Tianzhu, 464 from black yaks from Maqu, and 146 from black yaks from Luqu County, were collected and analyzed using ELISA to detect IgG antibodies against Fasciola hepatica. The overall F. hepatica seroprevalence was 28.7% (454/1,584), with 29.2% in white yaks (284/974) and 27.9% in black yaks (170/610). The seroprevalence of F. hepatica in yaks from Tianzhu, Luqu, and Maqu was 29.2%, 22.6%, and 29.5%, respectively. Female yaks (30.9%) had higher F. hepatica seroprevalence than male yaks (23.4%). Also, F. hepatica seroprevalence varied by different age group from 24.1% to 33.8%. Further, the seroprevalence ranged from 21.8% to 39.1% over different seasons. Interestingly, the season and age of yaks were associated with F. hepatica infection in yaks in the investigated areas. These findings provided a basis for further studies on this disease in yaks from 3 counties of Gansu Province in northwestern China, which may ultimately support the development of effective control strategies of fascioliasis in these areas.

“…Het aantal geïnfecteerde melkveebedrijven lijkt in andere landen toe te nemen (Fairweather, 2011;Fitzpatrick, 2013;KnubbenSchweizer & Torgerson, 2015;Olsen et al, 2015;Selemetas et al, 2015b). De prevalentie van leverbot in Nederland wordt niet gemonitord (buiten de gegevens die zijn verkregen van bedrijven die deelnamen aan GD tankmelkonderzoek) waardoor onbekend is of in Nederland eveneens sprake is van een toename in leverbot.…”

“…Het verschil tussen deze naburige bedrijven zal minder bepaald worden door de aan-of afwezigheid van een geschikte habitat voor de leverbotslak (Bennema et al, 2009;Olsen et al, 2015). Verschillen zullen waarschijnlijk bepaald worden door het toegepaste management, bijvoorbeeld de manier van weidegang en aankoop van (besmette) dieren (Olsen et al, 2015;Selemetas et al, 2015b). Verschillen tussen groepen in het aandeel besmette dieren binnen een besmet bedrijf worden vooral veroorzaakt door verschil in blootstelling van de verschillende diercategorieën aan leverbot (Byrne et al, 2016).…”

. Wat zijn de mogelijkheden om een leverbotinfectie van melkvee te voorkomen? Wageningen Livestock Research, Louis Bolk Instituut, Rapport 1029.Samenvatting NL Infecties met leverbot zijn in toenemende mate een knelpunt in de diergezondheid van grazende (of vers gras gevoerde) herkauwers. Leverbotinfectie leidt tot ziekte met economische gevolgen en voor melkgevende dieren zijn geen anthelmintica vrij beschikbaar. In dit project is het leverbotinstrument ontwikkeld met als doel om veehouders inzicht en handelingsperspectief te geven ten aanzien van de leverbotsituatie op hun bedrijf. In dit rapport worden de resultaten van het leverbotinstrument weergegeven en van een drietal preventieve maatregelen die zijn uitgeprobeerd.Summary UK Liverfluke infections are increasingly a bottleneck in the animal health of grazing (or fresh grass fed) ruminants. Liverfluke leads to disease with economic consequences and for lactating animals no anthelmintics are freely available. This project has been working on the development of the liverfluke instrument with the aim of providing dairy farmers insight and action perspective regarding the liverfluke situation on their farm. This report presents the results of the liverfluke instrument and of three preventive measures that have been investigated.
