A study was carried out to determine the prevalence and the species of liver flukes in indigenous adult cattle, to compare the diagnostic efficiency of fecal and post mortem examination and to assess the economic significance of bovine fasciolosis due to liver condemnation in the abattoir. Of the 406 livers and fecal samples examined, 57 (14.0%) and 20 (4.9%) were positive for fasciolosis. The most common liver fluke species affecting the cattle was Fasciola gigantica, 9.1% of cattle were infected with F. gigantica while, Fasciola. hepatica, mixed infections and unidentified or immature forms of Fasciola spp. were present in 3.2 %, 0.7% and 1 % of cattle, respectively. A retrospective abattoir survey revealed that the prevalence of fasciolosis was 12.7%. The prevalence of fasciolosis recorded in this study was lower than that reported by other researchers in this country. There was a strong relationship between fecal examination and postmortem findings of liver lesions, (K = 0.23) but under local conditions, postmortem examination was considered a better diagnostic tool for fasciolosis. Fasciolosis is of significant economic importance as the resultant liver condemnations caused an average loss of 4000 USD per annum. Hence, this disease deserves serious attention by the various stakeholders in order to promote the beef industry in the study area in particular and in the country in general.
开展了一项研究,以确定本地成年牛肝吸虫的流行率和种类,比较粪便检查和死后检查的诊断效率,并评估屠宰场因肝脏病变导致的牛片形吸虫病的经济重要性。在所检查的406份肝脏和粪便样本中,57份(14.0%)和20份(4.9%)的片形吸虫病检测呈阳性。感染牛的最常见肝吸虫种类是巨片形吸虫,9.1%的牛感染了巨片形吸虫,而肝片形吸虫、混合感染以及未鉴定或未成熟的片形吸虫种类分别在3.2%、0.7%和1%的牛中存在。一项屠宰场回顾性调查显示,片形吸虫病的流行率为12.7%。本研究记录的片形吸虫病流行率低于该国其他研究人员报告的流行率。粪便检查与肝脏病变的死后检查结果之间存在密切关系(K = 0.23),但在当地条件下,死后检查被认为是诊断片形吸虫病的更好工具。片形吸虫病具有重大的经济重要性,因为由此导致的肝脏病变平均每年造成4000美元的损失。因此,这种疾病值得各利益相关者予以认真关注,以促进特别是研究区域以及整个国家的牛肉产业发展。
