is one of the most common and fatal pathogenic gastrointestinal nematodes of small ruminants causing significant economic losses, particularly in low-income countries. A cross-sectional study was carried out in randomly selected small ruminants kept under traditional husbandry systems in the Apac district (now split into Apac and Kwania districts) in northern Uganda to assess the prevalence, intensity, and associated risk factors of infection from May 2018 to January 2019. Faecal samples were collected from a total of 768 randomly selected small ruminants (384 sheep and 384 goats) and examined for parasites using the floatation method and coproculture. The overall prevalence of in small ruminants was 73.3% (563/768) by faecal egg count and 70.6% (542/768) by coproculture. The mean number of eggs per gram of faeces in small ruminants was 2046 ± 107 and differed significantly across the host animals ranging from 1729 ± 120 (mean ± SE) in goats to 2364 ± 176 in sheep. Significant predictors of infection were the origin of study animals, animal species, breed of animal, age of study animal, faecal consistency, lactation, multispecies grazing, grazing method, and anthelmintic use. The findings of our study provide information on the current status of infections in goats and sheep under traditional husbandry systems in Uganda which are critical in designing effective control strategies for the disease.
是小型反刍动物中最常见且致命的致病性胃肠道线虫之一，会造成重大经济损失，尤其是在低收入国家。在乌干达北部阿帕克区（现分为阿帕克区和夸尼亚区），对随机选取的采用传统饲养方式的小型反刍动物进行了一项横断面研究，以评估2018年5月至2019年1月期间感染的流行率、感染强度及相关风险因素。总共从768只随机选取的小型反刍动物（384只绵羊和384只山羊）采集粪便样本，采用漂浮法和粪便培养法检测寄生虫。通过粪便虫卵计数，小型反刍动物的总体感染率为73.3%（563/768），通过粪便培养法的总体感染率为70.6%（542/768）。小型反刍动物每克粪便中的虫卵平均数为2046±107，不同宿主动物之间存在显著差异，山羊为1729±120（平均值±标准误），绵羊为2364±176。感染的显著预测因素包括研究动物的来源、动物种类、动物品种、研究动物的年龄、粪便稠度、泌乳情况、多物种放牧、放牧方式以及驱虫药使用情况。我们的研究结果提供了乌干达传统饲养方式下山羊和绵羊感染情况的现状信息，这对于设计该疾病的有效控制策略至关重要。
