A sheep trial was performed to evaluate two diagnostic assays, a faecal egg count reduction test (FECRT) and a coproantigen reduction test (CRT), for the diagnosis of resistance of Fasciola hepatica to triclabendazole (TCBZ). The FECRT defines successful TCBZ treatment as a 95% or greater reduction in fluke faecal egg counts (FECs) at 14 days post-treatment(More)
A sheep trial was performed to standardise a coproantigen reduction test (CRT) protocol for the diagnosis of resistance to triclabendazole (TCBZ) in Fasciola hepatica). The CRT employs the BIO K201 Fasciola coproantigen ELISA (Bio-X Diagnostics, Jemelle, Belgium) to test for the presence of F. hepatica coproantigens in a faecal sample. If it is(More)
The economic, veterinary, and medical impact of the parasite Fasciola hepatica, liver fluke, is difficult to alleviate due to increasing incidences of resistance to the principal anthelmintic drugs. These have occurred in widely separated regions. The rate of response to selection imposed by such drugs will be dependent on the genetic variation present in(More)
The tegument of the paramphistome, Gastrodiscoides hominis, is basically similar to that of other digeneans. It is folded into concentrically arranged furrows and ridges bearing numerous tightly packed tubercules, and extends into the oral cavity. An area of specialized tegument is present on the ventral surface, anterior to the disc region. Mitochondria(More)
Seventy indoor-reared sheep were divided into 10 groups to test the efficacy of the experimental fasciolicide, compound alpha (15mg/kg) against triclabendazole (TCBZ)-resistant and TCBZ-susceptible F. hepatica infections. Activity against the Sligo TCBZ-resistant isolate was tested at three time points post-infection (p.i.): 3 days, 4 weeks and 12 weeks(More)
Sheep infected with the Cullompton isolate of Fasciola hepatica were treated with triclabendazole at a concentration of 10 mg/kg at 12 weeks post-infection. Adult flukes were recovered from the liver and, where present, from the gall bladder at 48, 72 and 96 h post-treatment (pt). Gross changes to the spermatogenic cells of the testis were examined by(More)
