Article Synopsis
- Paramphistome infections, particularly from juvenile flukes, are causing increased health issues in ruminants, especially noted in tropical regions but now emerging in Europe.
- Recent studies in Ireland show a significant rise in rumen fluke infections, specifically the species Calicophoron daubneyi, compared to five years ago, indicating it may not be as minimal a threat as previously thought.
- Genetic analysis reveals that the same haplotypes of C. daubneyi are widespread across Ireland, suggesting the potential for resistance to current treatments, emphasizing the need for awareness in clinical diagnosis.
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 histology and ultrastructural alterations were visualised via transmission electron microscopy.
