Dicrocoelium dendriticum in cattle from Cypress Hills, Canada: Humoral response and preliminary evaluation of an ELISA

Fluke abundance versus host age for an invasive trematode (Dicrocoelium dendriticum) of sympatric elk and beef cattle in southeastern Alberta, Canada

“…Given the high prevalence in our sample of 1- and 2-year olds, this is unlikely. An alternative explanation is that in contrast to elk, some cattle accumulate worms as they age, despite the presence of anti- Dicrocoelium antibodies (Colwell and Goater, 2010). This interpretation is consistent with the results of studies involving domestic stock exposed to Fasciola hepatica , in which the presence of anti-fluke antibodies was not associated with protection from further infection (Bossaert et al., 2000; Cleary et al., 1996).…”

Constraints of using historical data for modelling the spatial distribution of helminth parasites in ruminants

“…Clinical signs in ruminants are not usually manifest, even in severe infections, and therefore, major lesions, due to liver impairment are detectable only at post-mortem examination [31,34]. Lesions are directly proportional to the parasitic burden [23] and chronic inflammation of the bile ducts [8]. In the early stages of the infection, reduced weight gain can be detected, but the infection is usually asymptomatic [34] resulting only in livers being discarded during meat inspection at slaughterhouses or with an appropriate coprodiagnostic analysis [35].…”

Evaluation of molecular methods for the field study of the natural history of Dicrocoelium dendriticum

“…Dicrocoeliosis has been reported in sheep Senlik et al, 2008;Sargison et al, 2012;Bosco et al, 2015), goats (Jithendran and Bhat, 1996;Khanjari et al, 2014), cattle (Colwell and Goater, 2010), buffalo (Rinaldi et al, 2009), deer (Otranto et al, 2007), camels (Wahba et al, 1997), pigs (Capucchio et al, 2009) and llamas (Dadak et al, 2013) in specific ecological niches around the world. This generalist definitive host strategy extends to sympatric rodent (Berry and Tricker, 1969), lagomorph (Sargison et al, 2012) and ungulate (Goater and Colwell, 2007;Beck et al, 2014) wildlife.…”
