Bovine fasciolosis, caused by Fasciola gigantica (F. gigantica) and rarely F. hepatica, is an economically important disease affecting cattle in tropical Africa. The aims of this study were to determine a year prevalence of bovine fasciolosis and correlate determinants of infection in slaughtered cattle at the municipal abattoir in Zamfara, Nigeria. Fasciola gigantica was detected in 15% (1740/11,562) cattle slaughtered during a daily postmortem examination (PME) between November 2016 and October 2017. This approach demonstrated an increase risk of liver fluke infection in older cattle (p = 0.001, AOR = 1.476, 95% CI: 1.188-1.832) and during rainfall (p = 0.003, AOR = 1.604, 95% CI: 1.176-2.187). Liver condemnation had been significantly found in hot-dry season (p ≤0.001, AOR = 0.518, 95% CI: 0.417-0.643) and adult cattle (p = 0.003, AOR = 1.726, 95% CI: 0.586-0.899). This study is an account of bovine fasciolosis prevalence and infection dynamics in part of the northwest region of Nigeria, which provides preliminary information for further studies to guide the design of appropriate control steps to lower the impact of the disease and safeguard public health.
牛 Fasciolosis，由 Fasciola gigantica（F. gigantica）引起，很少由 F. hepatica 引起，是一种影响热带非洲牛的具有重要经济意义的疾病。本研究的目的是确定尼日利亚赞法拉州市屠宰场屠宰牛的 Fasciola gigantica 年流行率，并对感染的决定因素进行相关性分析。在 2016 年 11 月至 2017 年 10 月期间，通过每日死后检查（PME）对 11562 头屠宰牛进行检测，发现 Fasciola gigantica 的检出率为 15%（1740/11562）。这种方法表明，老牛（p=0.001，AOR=1.476，95%CI：1.188-1.832）和降雨期间（p=0.003，AOR=1.604，95%CI：1.176-2.187）感染肝吸虫的风险增加。在热干季（p≤0.001，AOR=0.518，95%CI：0.417-0.643）和成年牛（p=0.003，AOR=1.726，95%CI：0.586-0.899）时，肝脏废弃显著增加。本研究报道了尼日利亚西北部部分地区的牛 Fasciolosis 流行率和感染动态，为进一步研究提供了初步信息，以指导设计适当的控制措施，降低疾病的影响，保障公众健康。
