Seasonality of bovine amphistomosis in the Southern province of Zambia was established after examining 268 faecal samples from cattle presented for slaughter at Turnpike slaughter slab, Mazabuka. Amphistomosis was found present throughout the year but the highest abundance rate was found during the post-rainy season (47.8%) and the lowest during the cold dry season (24.8%). In the rainy and post-rainy seasons, higher mean egg counts and cattle found positive were recorded than in any other season. The distribution of amphistome eggs was significantly different (p < 0.001) among the four seasons, with the rainy season having higher median egg counts than others. There were no significant differences in abundance rates between sexes or between ages of cattle. A similar seasonality to that of fasciolosis exists and may help in strategic management of Fasciola and amphistomes.
在对赞比亚南部省份马扎布卡收费站屠宰场宰杀的268份牛粪便样本进行检测后，确定了赞比亚南部省份牛双口吸虫病的季节性规律。双口吸虫病全年均有发现，但感染率最高的是雨后季节（47.8%），最低的是寒冷干燥季节（24.8%）。与其他任何季节相比，雨季和雨后季节的平均虫卵计数更高，检测呈阳性的牛数量也更多。四个季节中双口吸虫虫卵的分布存在显著差异（p < 0.001），雨季的虫卵计数中位数高于其他季节。牛的性别和年龄之间的感染率没有显著差异。双口吸虫病与肝片吸虫病存在相似的季节性规律，这可能有助于对肝片吸虫和双口吸虫进行战略管理。
