摘要

Reports of Calicophoron daubneyi infecting livestock in Europe have increased substantially over the past decade; however, there has not been an estimate of its farm level prevalence and associated risk factors in the UK. Here, the prevalence of C. daubneyi across 100 participating Welsh farms was recorded, with climate, environmental and management factors attained for each farm and used to create logistic regression models explaining its prevalence. Sixty-one per cent of farms studied were positive for C. daubneyi, with herd-level prevalence for cattle (59%) significantly higher compared with flock-level prevalence for sheep (42%, P = 0.029). Co-infection between C. daubneyi and Fasciola hepatica was observed on 46% of farms; however, a significant negative correlation was recorded in the intensity of infection between each parasite within cattle herds (rho = -0.358, P = 0.007). Final models showed sunshine hours, herd size, treatment regularity against F. hepatica, the presence of streams and bog habitats, and Ollerenshaw index values as significant positive predictors for C. daubneyi (P < 0.05). The results raise intriguing questions regarding C. daubneyi epidemiology, potential competition with F. hepatica and the role of climate change in C. daubneyi establishment and its future within the UK.

Daubneyi阳性，牛水平患病率（59％）显着高于绵羊植绒水平患病率（42％，P = 0.029）。在46％的农场观察到C. Daubneyi和FasciolaHepatica之间的共同感染;然而，在牛群中的每个寄生虫之间的感染强度中记录了显着的负相关性（rho = -0.358，p = 0.007）。最终模型显示阳光小时，畜群大小，对F.Hepatica的治疗规律，溪流和沼泽栖息地的存在，以及ollerenshaw指数值作为C.Aubneyi的显着阳性预测因子（P <0.05）。结果提高了有关C. Daubneyi流行病学的兴趣问题，具有F.Hepatica的潜在竞争以及气候变化在C. Daubneyi的作用及其在英国内的未来的作用。
