The prevalence and level of infection with Fasciola hepatica were assessed monthly over a 12-month period in goats slaughtered in the Haouz area, in correlation with the dynamics of Lymnaea truncatula populations. The infection rate was high in winter (23.8%) in January), and summer (17.1% in August), and relatively low in spring and at the beginning of autumn. The infected animals had a fluke burden range of 1-48; a mean of 13 was recorded in July. Lymnaeid snails were observed in their habitat throughout the year, but were more abundant during the hot months (July and August). Snails infected with F hepatica were found in February, June, July and August; their infection rate did not exceed 3%. These data enabled us to hypothesize that the main periods for transmission of fascioliasis were spring and fall; however, potential infections during other periods of the year were possible. The susceptibility of goats to infection with F hepatica appears to be similar to that reported in sheep.
在豪兹地区屠宰的山羊中，每月评估肝片吸虫的感染率和感染水平，为期12个月，并与截口椎实螺种群动态相关联。冬季（1月感染率为23.8%）和夏季（8月感染率为17.1%）感染率较高，春季和秋季初感染率相对较低。受感染动物的吸虫负担范围为1至48；7月记录的平均值为13。全年在其栖息地均观察到椎实螺，但在炎热月份（7月和8月）数量更多。2月、6月、7月和8月发现感染肝片吸虫的螺；其感染率不超过3%。这些数据使我们能够推测，肝片吸虫病的主要传播期为春季和秋季；然而，一年中其他时期也可能存在潜在感染。山羊对肝片吸虫感染的易感性似乎与绵羊中报道的相似。
