In order to establish seasonality of bovine fasciolosis in the Southern province of Zambia, 288 cattle were examined at slaughter at Turnpike slaughter slab for 1 year. The examination involved liver inspection and coprological examination. Liver condemnation rates were relatively high at the beginning of both the cold dry season and the rainy season (May/June and December, respectively). All cattle, regardless of age, had higher fluke abundances in the post-rainy season (39.1% young and 42.1% adult) while the lowest rates were in the hot dry season (13.3% young and 14.3% adult). On coprological examination, the highest abundance was in the post-rainy season (45.0%) and the lowest in the cold dry season (24.9%). From November (end of dry season) to February/March (end of rains), more fluke eggs were found than in any other period. The distribution of fluke eggs was significantly different (p<0.001) among the four seasons. Identified associations were: egg counts were highest in post-rainy (mean abundance=146) and lowest in cold dry season (mean abundance=118) at 95% confidence (CI 0.64-1.25). Differences in abundance observed according to origin, sex and age of cattle were not significant on both methods. Based on these results, it may be concluded that Fasciola gigantica was present throughout the year in cattle in Zambia but the abundance was highest in the post-rainy season and lowest in the cold dry season.
为确定赞比亚南部省份牛片形吸虫病的季节性规律，在Turnpike屠宰场对288头牛进行了为期1年的屠宰检查。检查包括肝脏检查和粪便检查。在寒冷干燥季节和雨季开始时（分别为5月/6月和12月），肝脏 condemnation率相对较高。所有牛，无论年龄大小，在雨季过后吸虫数量都较高（幼牛为39.1%，成年牛为42.1%），而在炎热干燥季节最低（幼牛为13.3%，成年牛为14.3%）。粪便检查显示，吸虫数量在雨季过后最高（45.0%），在寒冷干燥季节最低（24.9%）。从11月（旱季结束）到2月/3月（雨季结束），发现的吸虫卵比其他任何时期都多。四个季节中吸虫卵的分布有显著差异（p<0.001）。确定的关联为：在95%置信区间（CI 0.64 - 1.25）下，吸虫卵计数在雨季过后最高（平均数量 = 146），在寒冷干燥季节最低（平均数量 = 118）。两种检查方法中，根据牛的来源、性别和年龄观察到的吸虫数量差异均不显著。基于这些结果，可以得出结论，赞比亚的牛全年都感染巨片形吸虫，但数量在雨季过后最高，在寒冷干燥季节最低。
原文中“Liver condemnation rates”这里“condemnation”结合语境推测可能是“不合格率”之类意思，但不太确定准确专业术语，暂保留英文未翻译。
