A study on fasciolosis prevalence, gross pathological lesions, fluke genetic identification and coprological analysis was carried out in slaughtered cattle from one abattoir in Cape Verde. Of the 131 cattle inspected over two months, 12 (9.0%) presented fasciolosis-compatible lesions (FCL) that resulted in liver condemnation. The genetic characterization of the flukes collected, through restriction fragment length polymorphism analysis of PCR-amplified fragments (PCR-RFLP), confirmed the presence of ; therefore, being the first identification of this species in cattle from Cape Verde. Animals that released spp. eggs and, thus, responsible for environment contamination (positive shedders), were identified through coprological analysis (natural sedimentation technique). Of the 12 animals with FCL, samples from 11 were submitted to coprological analysis and 7 (63.6%) were found to be positive shedders. Furthermore, of the 82 animals with non-FCL, randomly selected for coprological analysis, 4 (4.9%) were also found to be positive shedders for spp. The results of this study, regarding species identification and coprological analysis, are epidemiologically important to update the information regarding fasciolosis in Cape Verde. The new data could help implement effective strategies for disease control and mitigation, consequently reducing economic loss and the level of animal and human infection from the One Health perspective.
对佛得角一个屠宰场宰杀的牛进行了一项关于片形吸虫病患病率、大体病理病变、吸虫基因鉴定和粪便学分析的研究。在两个月内检查的131头牛中,有12头(9.0%)出现了与片形吸虫病相符的病变(FCL),导致肝脏被判定不合格。通过对PCR扩增片段的限制性片段长度多态性分析(PCR-RFLP)对采集的吸虫进行基因特征分析,证实了 的存在;因此,这是在佛得角牛中首次鉴定出该物种。通过粪便学分析(自然沉淀技术)确定了排出 虫卵、从而造成环境污染的动物(阳性排虫者)。在12头有FCL的动物中,11份样本进行了粪便学分析,7头(63.6%)被发现是阳性排虫者。此外,在随机选择进行粪便学分析的82头无FCL的动物中,有4头(4.9%)也被发现是 物种的阳性排虫者。这项关于物种鉴定和粪便学分析的研究结果在流行病学上具有重要意义,可更新佛得角片形吸虫病的相关信息。这些新数据有助于实施有效的疾病控制和缓解策略,从而从“同一健康”的角度减少经济损失以及动物和人类的感染水平。
