BACKGROUND
Fasciolosis is a prevalent disease that significantly impairs the health and productivity of cattle and causes significant economic damage. Beyond the individually available studies with varying prevalence rates, there are no pooled national prevalence studies on bovine fasciolosis. Therefore, the current study aims to determine the pooled prevalence and economic significance of fasciolosis among cattle in Ethiopia.
METHODS
Cochrane's Q, inverse variance (I), sensitivity analysis, funnel plots, Begg's and Egger's regression tests were used to assess heterogeneity and publication bias. A random-effects model was used to calculate the pooled burden of fasciolosis among cattle.
RESULTS
The pooled prevalence of fasciolosis among cattle was 28.02% (7626/27,604) with (95% CI: 24.77%-31.26%). About 25.58% (3200/12,639) with (95% CI: 20.89, 30.27) and 30.45% (4426/14,965) with (95% CI: 26.05, 34.85) were found to harbour Fasciola through coprological inspection and post-mortem examination, respectively. Among a total of 14,965 livers of slaughtered cattle examined in municipal abattoirs, Fasciola hepatica (54.43%) was the predominant fluke identified compared to Fasciola gigantica (23.21%). Mixed infections of both species and unidentified immature flukes were detected in 15.04% and 7.02% of the affected livers, respectively. Regarding the severity of the pathological lesions observed, 35.08%, 49.31% and 15.61% of the livers were mildly, moderately and seriously infested, respectively. The total annual economic significance of fasciolosis among cattle from 21 reported studies was approximately 43,240,653.2 ETB (US$4,069,100.649). Increasing and decreasing trends of pooled fasciolosis prevalence were observed from 2010 to 2023 in coprological examination and post-partum inspection, respectively.
CONCLUSION
Therefore, bovine fasciolosis requires integrated control methods to address its influence on animal health and economic impact.
背景
肝片吸虫病是一种普遍存在的疾病，严重损害牛的健康和生产力，并造成重大经济损失。除了各项患病率不同的单独研究外，尚无关于牛肝片吸虫病的全国汇总患病率研究。因此，本研究旨在确定埃塞俄比亚牛群中肝片吸虫病的汇总患病率及其经济意义。
方法
采用Cochrane's Q检验、逆方差法（I）、敏感性分析、漏斗图、Begg检验和Egger回归检验来评估异质性和发表偏倚。使用随机效应模型计算牛群中肝片吸虫病的汇总负担。
结果
牛群中肝片吸虫病的汇总患病率为28.02%（7626/27604），95%置信区间为24.77%-31.26%。通过粪便学检查和死后剖检分别发现，约25.58%（3200/12639），95%置信区间为20.89%-30.27%，以及30.45%（4426/14965），95%置信区间为26.05%-34.85%的牛感染了肝片吸虫。在市立屠宰场检查的14965头屠宰牛的肝脏中，肝片形吸虫（54.43%）是检出率最高的吸虫，而巨片形吸虫的检出率为23.21%。在15.04%的患病肝脏中检测到两种吸虫的混合感染，7.02%的患病肝脏中检测到未鉴定的未成熟吸虫。关于观察到的病理损伤严重程度，分别有35.08%、49.31%和15.61%的肝脏受到轻度、中度和重度感染。21项报告研究中牛肝片吸虫病的年度总经济损失约为43240653.2埃塞俄比亚比尔（4069100.649美元）。在2010年至2023年期间，粪便学检查和产后检查中肝片吸虫病汇总患病率分别呈现上升和下降趋势。
结论
因此，牛肝片吸虫病需要综合防控措施来应对其对动物健康和经济的影响。
