The study was conducted to determine the prevalence of gastrointestinal (GI) parasites in cattle and sheep from three municipalities in the Colombian Northeastern Mountain.
Overall, 200 fecal samples were collected directly from the rectum in cattle and sheep. The presence of helminths eggs and coccidial oocysts in fecal samples was detected using McMaster and Dennis techniques. Identification of eggs or oocysts was done on the basis of morphology and size of the eggs or oocysts.
The global prevalence of GI parasites was 56.3%. Regarding the prevalence by municipalities, there was no statistical association (p>0.05), indicating that the prevalence was similar in the three municipalities. The prevalence of parasitic infection was higher in sheep (63%) as compared to that of cattle (50.5%), but the difference was nonsignificant (p>0.05). The most prevalent parasites were spp., , and Strongylida order. Regarding the results for spp., different degrees of positivity were observed, but there was no statistical association (p>0.05) with respect to the age group. Likewise, there was no statistical association (p>0.05) between the prevalence for Strongylida order and with respect to the age group.
Cattle and sheep in Colombian Northeastern Mountain were infected with helminths and coccidia. The prevalence values of GI parasites were moderate in both species warranting treatment. The presence of represents a risk factor to health public. Future studies are required to evaluate the parasitic dynamics throughout the year and the impact on animal production.
开展本研究以确定哥伦比亚东北山区三个市镇的牛和羊胃肠道寄生虫的流行情况。
总共直接从牛和羊的直肠采集了200份粪便样本。使用麦克马斯特法和丹尼斯法检测粪便样本中蠕虫卵和球虫卵囊的存在情况。根据卵或卵囊的形态和大小对其进行鉴定。
胃肠道寄生虫的总体流行率为56.3%。就各市政当局的流行率而言，不存在统计学关联（p>0.05），这表明三个市政当局的流行率相似。与牛（50.5%）相比，羊的寄生虫感染流行率更高（63%），但差异不显著（p>0.05）。最常见的寄生虫是 spp.、 和圆线虫目。关于 spp. 的结果，观察到不同程度的阳性，但在年龄组方面不存在统计学关联（p>0.05）。同样，圆线虫目的流行率与年龄组之间也不存在统计学关联（p>0.05）。
哥伦比亚东北山区的牛和羊感染了蠕虫和球虫。两种动物胃肠道寄生虫的流行率值处于中等水平，需要进行治疗。 的存在对公众健康构成风险因素。需要开展进一步研究以评估全年的寄生虫动态以及对动物生产的影响。
