Resumen de Editorial: Towards cost-effective fluke control in cattle
CATTLE and sheep farmers across the UK are concerned that it is becoming increasingly difficult to control the liver fluke, Fasciola hepatica, in their livestock. There is considerable variability in the incidence of clinical fasciolosis between years but, for the past 15 years, the overall trend has definitely been upwards, while the area where fasciolosis risk is significant has increased (van Dijk and others 2010). At least in part, these trends can be explained by changes in weather patterns, which increase the abundance of infective stages at pasture and/or the mud snail intermediate host (Caminade and others 2015). Meanwhile, in sheep flocks, resistance to triclabendazole, the only flukicide with activity against immature and adult flukes, is limiting treatment options (Fairweather 2011, Daniel and others 2012).
