| dc.description.abstract | Fascioloides magna is a trematode that occurs in the liver of infected wild and domestic ruminants mainly in North America. Previous research has shown a high occurrence of F. Magna in Southwestern Alberta. The following study was performed to produce an overview of the distribution of F. magna in Southwestern Alberta, because concerns were raised of this parasite circling within the wildlife population and possible transmission to cattle. To acquire the necessary data nine herds were selected for having contact with cattle (Beauvais Lake, Crowsnest Pass, Waterton, Castle Carbondale, Livingstone, Porcupine and Whaleback) or having no interaction with cattle (Jasper, Yaha Tinda). Fecal samples were obtained from March-May 2010. The fecal samples were processed using the flukefinder (Visual Difference, Moscow, Idaho, USA). Animals shedding F. Magna were demonstrated in five of the nine herds with percentages between 1,4 % and 76.7 %. Several factors that can affect the differences in occurrence of F.magna between the herds have been considered and options for further research are given. | |
